§ 25. Mr. Jacques ArnoldTo ask the Secretary of State for the Environment what proportion of pollution entering the North sea comes from rivers; and what proportion comes from British rivers.
§ Mr. Heathcoat-AmoryRivers are the most important source of North sea pollution, but not all other inputs can be reliably quantified. The combined effect of all United Kingdom rivers flowing into the North sea is to contribute about 20 per cent. of riverborne pollutants.
