The release of any of these substances into waterways must be avoided. In case of accidental spillage cleaning must be carried out using absorbent materials instead of rinsing or pouring jets of water.

In the case of substances included in the list of priority hazardous chemicals under EU water policies, elimination or substitution must be recommended according to the principles stated in Directive 2000/60/EC about “the cessation or phasing-out of discharges, emissions and losses of the substances, including an appropriate timetable for doing so. The timetable shall not exceed 20 years after the adoption of these proposals by the European Parliament and the Council”.
