Minamata Convention: COP4
Minamata Convention: COP4

Fourth Conference of Parties (COP) to the Minamata Convention on Mercury

November 1-5, 2021  Bali, Indonesia

The Government of Indonesia will host the fourth meeting of the Conference of the Parties to the Minamata Convention at the Nusa Dua Convention Centre, Bali.

The Minamata Convention on Mercury is the first global agreement specifically designed to address contamination from a heavy metal. The 50-ratification milestone required for the Convention to enter into force was reached in May 2017. As a result, the Convention became legally binding for all its Parties.

BRI's Contribution to the Minamata Convention

As experts in the field of mercury science, BRI researchers were invited by U.S. government officials to participate as a nongovernmental organization (NGO) during the negotiating process of the Convention. The meetings of the International Negotiating Committee (INC) that preceded and have continued since the adoption of the Convention include delegates from more than 140 countries and numerous NGOs interested in reducing mercury pollution. BRI has participated in five of the first seven INC meetings, and each subsequent Conference of Parties.

BRI serves as co-lead of the UN Environment’s Mercury Air Transport and Fate Research partnership area. As a co-lead, BRI assists developments for a globally coordinated mercury monitoring and observation system. In addition, BRI aids three UN agencies in implemention of Minamata Convention Initial Assessment (MIA) activities in many countries, as (1) an Executing Agency with UNIDO, (2) an International Technical Expert with UNDP, and (3) an International Technical Expert with UN Environment. These MIA activities are designed to assist countries with developing strategies for ratifying and ultimately implementing the Convention.

Global Mercury Monitoring in Biota (2019)

Technical Information Report on Mercury Monitoring in Biota (2019)

Monitoring mercury in biota (plants and animals) provides a pathway for understanding spatial gradients, temporal trends, and environmental magnitude of concern that cannot be ascertained in air, water, or sediment. Emphasizing upper trophic level biota for monitoring ultimately provides a confident ability to asess whether the global input of anthropogenic mercury into the environment is safe or harmful to fish, wildlife and humans.

Global Mercury Inventory Synthesis (2019)
Global Mercury Inventory Synthesis - Technical Report (2019)

This publication highlights the results of a pilot study that Biodiversity Research Institute, in collaboration with UN Environment, developed to examine and summarize the national mercury inventories of 43 countries that have completed the Minamata Initial Assessment process. This pilot study quantifies the relative contributions of sectors (ten primary source categories) to mercury emissions and releases, within a set of countries representing varied global regions and socio-economic backgrounds.

Mercury in the Global Environment: Understanding Spatial Patterns for Biomonitoring Needs of the Minamata Convention on Mercury (2018)

Mercury in the Global Environment presents data on mercury concentrations in marine and freshwater biota extracted from the GBMS database, as well as mercury data relative to global fisheries capture data from the Food and Agriculture Organization (FAO). Mercury concentrations from various taxa are presented and compared geographically. Together, these data help inform decision makers of species in which and locations where mercury presents a risk to human health and the environment. This report aids parties of the Minamata Convention on Mercury during their ratification and implementation processes.

Mercury in the Global Environment: Marine Mammals (2017)

Marine mammals migrate across the globe, either forgaging on the smallest of animals (krill) or prey on the largest, but all depending on uncontaminated food sources. Over the past century, mercury released through industrial processes has been entering and accumulating in the world’s oceans, putting marine mammals at risk. To help illustrate the impacts of methylmercury biomagnification (increased toxicity as toxins moves up the food web) and bioaccumulation on marine mammals, we have identified five particularly affected groups: toothed whales, baleen whales, pinnipeds (seals and walruses), people (in particular, aboriginal subsistence communities), and the polar bear. 

Mercury in the Global Environment: Tuna (2018)

Tuna are regularly listed on fish consumption advisories. Yet, tuna are consistently among the top five commodities in the global fish market. Skipjack, albacore, and yellowfin are most commonly processed for canned products, while bluefin are valued for direct consumption. This publication summarizes GBMS and FAO data from nine tuna species, and examines trends by ocean basin through the lenses of human and environmental health.

Phasing Out/Phasing Down Mercury-added Products: What to Know about Consumer and Commercial Products Outlined in the Minamata Convention (2018)

The Minamata Convention aims to reduce mercury use in products and dental amalgam. This booklet focuses on mercury-added products, as outlined in Article 4, which prohibits the manufacture, import, and export of specific mercury-added products by 2020. In addition, it discusses Article 11, which addresses mercury wastes.

Local, Regional, and Global Biomonitoring: Understanding Mercury Exposure through Monitoring At-risk Species (2018)

Fish and wildlife provide important information on the risks and impacts of mercury pollution on environmental and human health. Biomonitoring is the process of assessing the health of organisms and ecosystems through changes in mercury risk and exposure over time. This publication describes biomonitoring efforts outlined in Article 19 of the Minamata Convention on Mercury, which lists fish, sea turtles, birds, and marine mammals as organisms to be monitored.
