Persistent Organic Pollutants (POPs) are a group of organic chemicals that remain stable over long periods of time and are toxic to humans, animals and the environment.
Some POPs are made for particular uses - these are known as intentional POPs, for example:
Other POPs are released into the environment from burning fossil fuels or waste -these are known as unintentional POPs, for example:
People are mainly exposed to POPs through food. POPs which are released into the environment can enter the food chain when they are deposited on soil or through our rivers, lakes and seas. Therefore, it is important to prevent the release of POPs into the environment in order to prevent damage to the environment and protect human health.
Under the international Stockholm Convention on POPs each participating country must take administrative and legislative actions to prevent the environmental impacts of POPs. The requirements of the Stockholm Convention are enacted into EU law by Regulation (EU) 2019/1021 and Irish law by S.I. No. 146 of 2020. The Republic of Ireland signed up to the Stockholm Convention in 2010 and under Article 7 of the Convention, is required to develop and regularly update a National Implementation Plan on POPs as new POPs are restricted or banned.
The EPA, as the competent authority, reviewed and updated the National Implementation Plan on POPs in 2018, in consultation with a number of public authorities, national stakeholders and the public. It includes an assessment of POPs in Ireland and details an Action Plan of measures to be carried out to support the control of POPs.
As part of the POP’s Action Plan, the EPA are investigating the risks posed by certain POPs to human health and the environment in the Irish context including PFAS in fire-fighting foams, POPs in landfill leachate and PCBs in building materials. Further details on these studies are available through the links provided below.
