A mechanism for monitoring potential emerging contaminants which may pose a risk to the water environment was established when the Directive on Environmental Quality Standards was updated in 2013. The first watch list was adopted in 2015 (in Decision 2015/495) and includes the following chemicals:
- the natural hormone oestrone (E1);
- three (macrolide) antibiotics;
- several pesticides;
- a UV filter (a chemical that prevents UV light getting though, as used in sun cream); and
- an antioxidant used as a food additive.
Issue 473 (7 October 2016) of the EU Science for Environmental Policy has just highlighted the findings of a study reviewing data on the worldwide occurrences of these substances and options for their removal from wastewater, and from surface and groundwater used to produce drinking water.
