§ Dr. David ClarkTo ask the Secretary of State for the Environment what assessment he has made of the amount of pesticides which enter rivers each year; and if he will make a statement.
§ Mr. Trippier[holding answer 26 March 1990]: Surveys were undertaken in 1989 to identify the concentrations in rivers of their pesticides included on the red list of substances most dangerous to water. Results of the surveys are expected shortly. Further monitoring for these substances will be undertaken this year as part of a Paris Commission comprehensive survey of riverine inputs, in which all signatories of the Paris convention are participating.
