Experts find dangerous chemicals in Czech fish

Czech scientists and environmental experts have found evidence of dangerous chemicals in Czech fish. Research carried out by the environmental organisation Arnika, which studied fluvial sediment and fish throughout the Czech Republic for the course of one year, found that a majority of them contained bromine and fluorine substances that persist in the environment for long periods of time and are not normally monitored. Perfluorinated compounds found the water system will, if consumed, be stored in the body and remain there. Some of the substances discovered are forbidden by the Stockholm Convention on Persistent Organic Pollutants, however legal limits have not yet been established.
