A report on chlorinated paraffins in urban air in Nordic countries has been published by the Nordic Council of Ministers. Air samples were collected in three Nordic countries (Finland, Iceland and Norway) both during winter and summer. Short-, medium- and long-chain chlorinated paraffins (SCCPs, MCCPs, LCCPs) were screened for and were detected in almost all samples.

In October 2021 the Nordic Screening Group held an online seminar on Prioritization of Substances with the goal to exchange information on the prioritization of hazardous substances for environmental monitoring. Presentations and the agenda for the workshop can be found on our website!

About Nordic Screening

There are approximately 100.000 different chemical substances in use within the EU borders. We know that some of these are very hazardous and pose a risk to the environment. However, for the vast majority of substances, we simply don’t have the knowledge to decide whether they pose a risk to the environment at the present time or maybe will do so in the future. To better understand such risks, one important first step is to measure these chemicals in the environment, to see whether they can be detected in water, soil or in living organisms. If the substances are persistent, bioaccumulative or toxic (PBT), they are regarded as hazardous. Substances with known hazardous properties are to a large extent regulated and included in national monitoring programs in the Nordic countries.

The aim of the Nordic environmental screening is to obtain a snapshot of the occurrence of potentially hazardous substances, both in regions most likely to be polluted as well as in some pristine environments. The focus is on less known, anthropogenic substances and their derivatives, which either are used in high volumes or are likely to be persistent and hazardous to humans and other organisms.
