Fluorinated substances pollute for billions of Euros every year
Perfluoroalkyl and polyfluoroalkyl substances (PFASs), also known as fluoroalkyl substances (or fluorinated substances), is a large group of substances used in a wide range of industrial applications as well as in consumer products to make them water- grease- and dirt repellent.
Fluorinated substances have been on top of the international agenda for some time. The substances degrade very slowly in the environment and some of them are bio accumulative and toxic. International agreements and EU-regulations have therefore been introduced, but exposure still take place.
The use of PFASs is widespread and these substances are highly persistent in the environment. Almost all people have PFAS in their bodies today. Exposure occurs primarily through contamination of drinking water. However, exposure via other routes also occurs. When these substances are released to the environment, there is a risk of causing long-term problems due to contamination of e.g. surface- and groundwater and at a later stage contamination of drinking water. Health- and environmental problems can therefore be built up and remain for a long time.
A growing number of health effects have been linked to the exposure of fluorinated substances. The findings indicate that the costs are substantial.
In Europe and the USA, hundreds of millions of euros have already been spent on upgrading drinking water treatment and remediation of contaminated soil with fluorinated substances. If all the estimated polluted areas were to be treated, similarly the cost for such activities would be between 46 million and 11 billion euros for the Nordic countries. The corresponding figure for the EEA is estimated to be between 17 and 171 billion euros. The writers of the report underline that the uncertainties of the estimations are quite large. However, based on the literature review carried out, there is a firm basis for concluding that the lower bound estimates will be exceeded and that a best estimate in the order of 10-20 billion euros for the whole EEA is plausible for the environmental related costs for the EEA.
To raise awareness
This study is providing an assessment that is intended to be used to raise better awareness of the costs and long-term problems that the use of fluorinated substances may cause for the environment or human health. This information can be used as an input to the work with further risk management of fluorinated substances.
The project was carried out by consultants from the companies Milieu and EMRC and financed by the Nordic Council of ministers, the Swedish Chemicals Agency and the Danish Environmental Protection Agency. The Norwegian Environmental Agency and the Environment Agency of Iceland also supported the work of this project.
