And besides these collective efforts, most large companies now also have lists of chemicals they ban and those they prefer, such as Nike's Considered Chemistry, Boots' Priority Substances List, SC Johnson's Greenlist and Sony's Green Partners Standards.
The minimum measuring frequency for priority substances is currently set at once per month.
They comprise a combination of two priority substances and two rivers, representative for Western Europe.
They should be used to identify individual priority substances for more specific testing.
Chemical analyses were mainly focused on compounds which are identified as priority substances.
The European Water Framework Directive classifies diuron as one of the priority substances, being a hazardous pollutant [1].
Additional analytical challenges may arise when Member States have identified their river basin specific pollutants and after revision of the list of priority substances.
For instance, MP have been shown to contain the WFD priority substances di ethylhexyl) phthalate (DEHP), nonylphenol, octylphenol, and PAHs (2008/105/EC, Annex II).
Monitoring studies often focus on the list of priority substances as defined in the EU water framework directive [7, 9, 10].
However, the present process of ranking and selection of priority substances and setting of EQS does not adequately address persistent and mobile substance properties.
The chemical status assessment is based on compliance with legally binding Environmental Quality Standards (EQSs) for selected chemical pollutants (priority substances) of EU-wide concern.
