Part 1: Introduction

The deadline for the tender is: 12/02/2018

Part 2: About the EEB and the Zero Mercury Working Group

  • Created in 1974, the EEB is now the largest federation of environmental citizens’ organisations in Europe. It currently consists of over 140 member organisations in more than 30 countries (virtually all EU Member States plus some accession and neighbouring countries), including a growing number of European networks, and representing some 15 million individual members and supporters.
  • We work on a vast array of environmental issues and our policy officers work with experts, our members, politicians and the media to protect and further develop environmental policies.
  • The Zero Mercury Working Group (ZMWG) is an international coalition of over 95 public interest environmental and health non-governmental organizations from more than 50 countries from around the world formed in 2005 by the European Environmental Bureau and the Mercury Policy Project.  ZMWG strives for zero supply, demand, and emissions of mercury from all anthropogenic sources, with the goal of reducing mercury in the global environment to a minimum.  Our mission is to advocate and support the adoption and implementation of a legally binding instrument which contains mandatory obligations to eliminate where feasible, and otherwise minimize, the global supply and trade of mercury, the global demand for mercury, anthropogenic releases of mercury to the environment, and human and wildlife exposure to mercury.

Part 3: Tender


The Zero Mercury campaign at the EEB would like to build a new website for Zero Mercury Campaign/Zero Mercury Working Group based on the existing website available at www.zeromercury.org – while maintaining the URL.

Active since 2005 the Zero Mercury Campaign, having grown into the Zero Mercury Working Group has a long history of action. We would like to see a visual update of the website, to a more modern and user-friendly visual look. The division of sections, and their related subsections should be divided between introductory and advanced mercury issues.

-          We would like to convey through our website an approachable and educational tool for mercury related issues.

-          On the other hand, on separate tabs we would like to make available the recent activity related:

  1.  to project implementation through our members in different countries, and
  2. the developments related to policy at international and EU levels.

The distinction between the “introduction to mercury” section and the “Policy” and “Projects” sections should be clear. We would like a visualization of introducing the general public to mercury through its various topics (processes, products etc), and then at the end of the page have a link where an individual can arrive at how the Zero Mercury Working Group is working on that specific issue at project and policy level as relevant. Simultaneously however, we would like to have a tab where stakeholders familiar with mercury issues and/or our work, can get directly to the advanced information without going through the introductory informational section or tabs.

We are looking for a proposal that explains in detail how the concept note below can be implemented.

Tender: revamp a website

  • The Zero mercury Working Group is looking to revamp its website. It currently does not do justice to the work carried out by the 95+ members organisations. This means a much more advanced structure with more visuals, conveying the image of a serious, trustworthy NGO coalition.
  • The new website should be Wordpress-based, allow for easy management internally and coded in an open and accessible way to permit other third party developers to easily adjust.
  • We would like the website to be a one-stop-shop for individuals that are new to mercury issues and simultaneously provide a platform where stakeholders familiar with mercury issues can find updates on international policy developments and relevant project information. 
  • The audience of the Zero Mercury Working Group website includes our members, representatives of EU institutions and member state governments, journalists, academics, other NGOs, progressive business and members of the public.

Please include the following and their related costs (separately) in your quote:

  • Design and development of new easy to navigate website
  • Transfer of data from the current our current CMS system, Joomla.  
  • Annual costs for domain name and hosting (including backup). We may decide to handle this ourselves depending on the quotes provided.

  • Possibility of archiving the content of the existing website

Home page

The home page is meant to be a public oriented landing page for individuals wishing to learn about mercury. The first image should be a large slider which in principle will not change over time. The slider will include 4-5 pictures referring to introductory information about the challenges surrounding mercury pollution, but also to some of the priority areas we work on.

Above it, a horizontal menu, with dropdown elements can be displayed, dividing between general mercury information, the policy work that ZMWG does along with current projects and other elements (to be detailed at a later stage e.g about us etc). Below the slider there will be some space to describe ZMWG group as an organization and post our latest news. There should also be space to include a footer providing our location and contact information.

As examples please see http://www.artisanalgold.org/ or www.sradev.org


The website should provide country-specific pages/posts with contact information for our different national partners, in addition to a description and updates of relevant projects that they do appearing within our website (via posts) apart from linking back to national websites. Accessing these country specific pages should be done through a map, e.g.  found on “About us” page. The map needs to highlight somehow differently countries where EEB/ZMWG are funding (or have funded) directly projects, whilst providing a link to that campaign (page/post).

We would also need to post updates about the relevant projects/campaigns, that will simultaneously appear in the “What’s new” section of the home page.

Technical prerequisites:

The CMS should be WordPress to align with our other websites. The current site is working with Joomla.

Visual identity / look and feel:

We do want to update, but not reinvent the visual identity of the Zero Mercury Campaign/ Working Group.

The Zero Mercury logo stays unchanged and is our branding basis. We would like the look and feel of the new website to be more visually oriented, as now it feels a bit text-heavy.

Footer: Logos and disclaimers of EC will need to go somewhere at the bottom 

Measuring devices PDF Print

Mercury is used in many measuring devices mainly in hospitals, clinics and doctors’ offices but also for in other measuring and control equipment.

Mercury is contained in many common medical measuring devices: sphygmomanometers (blood pressure devices), thermometers (specifically body temperature thermometers but also others) and a number of gastro-intestinal devices, such as cantor tubes, esophageal dilators (bougie tubes), feeding tubes and Miller Abbott tubes.

As in other types of instruments, mercury has traditionally been used in these devices because of its unique physical properties, including the ability to provide highly precise measurements. These instruments include barometers, manometers, but also porosimeters, pycnometers, hygrometers, tensiometers, gyrocompasses, mercury-containing reference electrodes, hanging drop mercury electrodes, gas flow meters, and coulter counters among others.

Relevant legislation and NGO policy work

 In the EU - the European Commission included an action (Action 7) in view of  restricting the marketing for consumer use and healthcare of nonelectrical or electronic measuring and control equipment containing mercury, in the 2005 EU Strategy on Mercury.

Directive 2007/51/EC, was published on 2 October 2007 in the Official Journal of the European Union.  
It can also  be found in all EU languages. It prohibits the placing on the market of all mercury fever thermometers (for consumer and professional use), and for  all other measuring devices intended for sale to the general public (e.g. manometers, barometers, sphygmomanometers, thermometers other than fever thermometers).  It came into force on 3 April 2009.

The NGO activities and follow up of this issue are presented  here in chronological order :

In October 2009, Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) published their Opinion on: Mercury Sphygmomanometers in Healthcare and the Feasibility of Alternatives (380KB)

Beyond the above restriction, the EC prepared a report with all relevant elements concerning potential restrictions in the use of mercury in measuring devices for professional use and in healthcare (e.g. sphygmomanometers in hospitals/clinics, porosimeters etc) which was sent this to the European Chemicals Agency (ECHA).  The EC  requested ECHA to evaluate the report  and prepare, if appropriate, an Annex XV Dossier as foreseen by Article 69 of REACH. Subsequently, further discussion and consultation with the stakeholders will be carried out by appropriate means by ECHA when preparing Annex XV restriction report. ECHA will make the finalised Annex XV report publicly available and invite all interested parties to submit comments and contributions (see Art 69(6)). The Annex XV report is now available.; comments are due by 24 March 2011.

The Risk Assessment and Socio-economic Analysis Committees of ECHA (RAC, SEAC) will give their opinions on the suggested restriction taking into account comments submitted by the interested parties during the public consultation (see Art 70 and 71). [expected by March 2011]. Furthermore, interested parties will have a possibility to comment the draft opinion of SEAC. [expected summer-autumn 2011]

For more information, about the timetables and procedures, please, consult the new ECHA website at http://echa.europa.eu/reach/restriction_en.asp

Please see the EEB comments on the suggested restrictions on mercury use in measuring devices that was submitted during the public consultation that was concluded on the 24 March 2011. Additional comments on Phenymercury compounds were also submitted at the same time.

Furthermore,  some individual countries have already taken action to ban or restrict the use of some or all products containing mercury such as Denmark, France, the Netherlands, Sweden, Norway.  Canada and the UShave also taken similar steps


US: As of October 2, 2008, thirteen states have laws that limit the manufacture, sale and/or distribution of mercury fever thermometers: California, Connecticut, Illinois, Indiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, Rhode Island, Oregon, Washington. The Health Care Without Harm Web site presents information on specific state laws and municipal ordinances.

Information is also provided at http://www.epa.gov/hg/consumer.htm#bat bat and at http://www.newmoa.org/prevention/mercury/modelleg.cfm

HCWH has been working globally to promote mercury free hospitals. The Health Care Without Harm Web site presents information on specific state laws and municipal ordinances.

Health Care Without Harm and the World Health Organization are co-leading a global initiative - Mercury Free Healthcare-  to achieve virtual elimination of mercury-based thermometers and sphygmomanometers over the next decade and their substitution with accurate, economically viable alternatives.  The initiative is a component of the UN Environment Programme's Mercury Products Partnership.


Information on the measuring devices


Mercury is used in certain thermometers, where a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts in a consistent manner and the temperature can be read from the scale. A mercury thermometer can be easily identified by the presence of a silver bulb. If the bulb is red, blue, purple, green or any other color, then it is not a mercury thermometer.

Mercury thermometers can be used to determine body temperature (fever thermometers), liquid temperature, and vapor temperature. Mercury thermometers are used to measure the temperature of liquids and vapors in households, laboratory experiments at educational and medical institutions, and industrial applications. Common household uses of mercury thermometers include fever thermometers and oven, candy and meat thermometers.

Fever thermometers

Mercury fever thermometers are made of glass the size of a straw, with a silvery-white liquid inside, and are a common item in many households, schools and medical facilities. There are two general types of mercury thermometers that measure body temperature:

  • oral/rectal/baby thermometers, containing about 0.61 grams of mercury; and
  • basal temperature thermometers, containing about 2.25 grams of mercury.

Alternative Mercury-free Fever Thermometers that are reliable and accurate, are available in the market today.  Alternatives that are most comparable in cost and use to the mercury fever thermometer include battery and solar powered digital thermometers.  These can all be used orally, rectally, or in the armpit. 

When choosing a battery powered digital thermometer, it is advisable to select one that contains a replaceable battery. The battery is a button cell battery and may contain a small amount of mercury, so it should be recycled through a local battery collection program or the existing household hazardous waste collection center.

Within the educational and medical sectors, mercury thermometers may be used in many applications, including chemical experiments, water and acid baths, blood banks, ovens and incubators

Industrial uses of mercury include: use in power plants and piping, chemical tanks and vats, heating and cooling equipment, breweries, canneries, bakeries, candy making, dairies, ships, wineries and distilleries, and paint kettles.

Thermometer cleanup and disposal:When a thermometer breaks during usage or if it is not properly disposed of, it will release mercury vapors that are harmful to human and ecological health. The US EPA website has information on what to do when a thermometer breaks or spills.

Many states and local agencies have developed collection/exchange programs for mercury-containing devices such as thermometers. Some counties and cities also have household hazardous waste collection programs. 


Blood pressure gauges (Shpygmomanometers)

A sphygmomanometer or blood pressure meter is a device used to measure blood pressure, comprising an inflatable cuff to restrict blood flow, and a mercury or mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded. Manual sphygmomanometers are used in conjunction with a stethoscope.

The mercury sphygmomanometer has long been considered the “gold standard” of blood pressure measurements because all medical personnel have been trained to use it, the blood pressure readings are fairly reliable, it is often (mistakenly) believed that the device never needs to be calibrated, and it can be used universally – including in special clinical conditions such as arrhythmia, pre-eclampsia and certain vascular diseases where
electronic sphygmomanometers may be less reliable. While mercury-free semi-automated and automated (electronic) sphygmomanometers that measure blood pressure without a stethoscope are, in recent years, more commonly used than mercury devices, they have some limitations.
“Manual” mercury-free sphygmomanometers – used together with a stethoscope –  are direct substitutes for mercury sphygmomanometers. Such substitutes include the aneroid sphygmomanometer, which typically uses a pressure dial instead of a mercury manometer; the digital sphygmomanometer, which shows blood pressure readings on a digital display; and the newer hybrid sphygmomanometer, which shows blood pressure
readings on a non-mercury (e.g. liquid crystal display) column.
In past years, most manual mercury-free sphygmomanometers were subject to a range of problems such as unreliability, fragility, need for more frequent calibration, etc., that gave them a reputation for substandard performance. Even now, the reliability and performance of a sphygmomanometer depends to a large extent on the design and manufacture, although it may also be strongly influenced by the frequency of
maintenance and calibration, the training and experience of the user, the manner in which it is used, etc.
While a number of manual mercury-free sphygmomanometers now on the market have been independently tested (“validated”) and determined to be fully substitutable for mercury sphygmomanometers, some are more expensive to purchase and may have a shorter lifetime than a mercury sphygmomanometer. Combined with the reticence of some health care professionals to trust mercury-free instruments, some hospitals and especially general practitioners in some countries have been reluctant to adopt them.Mercury may be released from manometers and valves during use, as it is often necessary to top up the mercury. Furthermore, end of life sphygmomanometers (and other mercury containing devices) would need to be discarded carefully - as hazardous waste. Especially at health care facilities, hazardous waste management is a critical task not only because of the diversity and quantities of waste handled, but also because substandard practices have the potential to harm the reputation of the entire facility. The failure of a number of health care facilities to treat mercury (and probably other hazardous wastes) properly, may have as a result mercury wastes ending in waste incinerators, or landfills causing emissions to air, water and soil,  increasing the risks to human health and the environment.

 Other measuring devices


A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries. Barometers use large quantities of mercury (around 999 g more than a fever thermometer). Any barometer breakage poses an enormous risk of contamination and severe health effects, not to mention significant clean up costs. Mercury free barometers, both aneroid and digital, are already available in the market, and can be transported without the need for hazardous packaging. Breakage of mercury barometers does not only happen in the manufacturers’ workshop, but  can and do occur in schools, homes, and other buildings. These breakages can involve significant clean up costs (evacuation & closure of schools, hazardous waste clean up & disposal measures), risk of contamination into the environment through improper disposal, and risk of health effects (e.g. through direct inhalation).


Porosimetry is a major mercury user.The purpose of porosimeters is the measure of the porosity of a sample – that could be sintered filters, catalytic converters, fuel cells, bone replacement materials, ceramics, etc. The advantage of mercury is that it is a fast, reliable technique covering a wide range of pores from 0.003 ìm to 400 ìm. There are various alternatives, but none is ideal for certain substances and/or certain pore sizes. Further, as in the case of sphygmomanometers, there are certain validation standards that would also have to be revised in order to move away from mercury porosimetry. After testing, about 4% of mercury remains in a typical sample, the rest is recovered for re-use by the company that is doing the testing. That means that over a period of time, testing 25 samples, you use 100% of your quantity of mercury in the machine. The question is what happens to the mercury that remains in the samples. Industry assures us that it is possible to recycle 100%. Due to the fact that this process is normally done in research labs, one would hope that a high rate of recycling is carried out – but there is no information to confirm that. For the research that was done for the 2008 COWI/Concorde study for DG Environment, there was an estimation of 25-30% of recycling in addition to a certain amount of mercury in samples that goes to final disposal – for example in salt mines in Germany. However, there is little real data to back up these numbers.

Even though several measures have been taken to control the use and emissions of mercury in the EU, some uses of mercury still remain, such as its use in the following measuring devices used by industry and professionals: Barometers, manometers, sphygmomanometers and strain gauges used to measure pressure, and thermometers to measure temperature. Porosimeters, pycnometers and metering devices for determination of the softening point measure different parameters related to the structure and porosity of a sample. Mercury electrodes used with specific devices like polarographs, for instance to determine trace elements in the environment and in biological fluids.

Barometers, manometers, sphygmomanometers, strain gauges and thermometers contain mercury as an integral part of the device whereas metering devices for determination of the softening point, polarographs (using mercury electrodes), porosimeters and pycnometers use mercury during the measurement and need to be refilled regularly.

Mercury-free alternatives are already available and dominate the market for most of the measuring devices. The alternatives are often electronic devices or devices making use of other liquids such as alcohols for their functioning. For porosimeters and mercury electrodes used in voltammetry no technically feasible alternatives have been identified which would cover all application areas.

Mercury electrodes (polarography) 

Polarography is an electrochemical analytical technique which is used in chemical labs, in universities, in industry. Mercury is used as a sensor electrode. Voltage is applied, and currents are measured to this sensor. It is mainly used to determine toxic traces and low concentrations of heavy metals such as lead, cadmium, chromium or mercury.The center of the whole device is a glass vessel and three electrodes immersing in this glass vessel, including the mercury sensor. The mercury electrode is a glass capillary, from which a small mercury drop is extruded. In the glass vessel the sample we want to analyze is introduced. At the end of the determination the mercury drop falls off to the bottom of the vessel and from there it can be collected at the end of the measurement. Filling of the electrode is typically 6 milliliters which is approximately 80g mercury. Under normal circumstances this will last for half a year to one year of every day use. Based on the consumption of mercury and estimated number of polarographs worldwide we assume that the total consumption is about 250 to 350kg worldwide. From a (mercury) life cycle perspective of the user, usually, the mercury is purchased from a supplier, it is used in a lab, collected in a close container and finally returned to a recycler.

Alternatives: the technique is used for the determination of heavy metals. There are other techniques existing that have a similar application. They are either non-electric techniques – for example optical/spectroscopic techniques – or other sensors (with reduced mercury content or completely mercury-free sensors) using similar principals of measurement as polarography. There are spectroscopic techniques that are very well established, which are usually the standard techniques in most of the labs worldwide. They are good for the majority of application. However,there are some limitations:

 Only total element concentration detection.
 High investments (purchase, running)
 Problems with some sample matrices (e.g. sea water, pure chemicals)
 Limited mobility
 Laboratory infrastructure required

Besides liquid mercury as a sensor there are other sensors existing, some of them are commercially available and some others are still in a research state. Typically they are based on carbon or on noble metals like gold or platinum. These sensors have quite severe restrictions – this is why most of them are only used in research fields and not in routine. If we look into industry we have nearly no users using such sensors because of the restrictions. Their advantages are that they can replace some mercury applications and they are sometimes even more sensitive than the mercury sensor.

However, the most important restriction is that they are not as robust as the mercury sensor, so when it comes to reliability the classic electrode is better. The alternative sensors need more maintenance, show more interferences, require more operator skills and sometimes the alternatives even contain toxic metals like mercury.
