Abstract:
Routine river quality sampling for pesticides in the Chyandour Brook on 30 January 1990 revealed 290 ng/1 of tecnazene at the A30 roadbridge monitoring point. Although the concentration of tecnazene was below the tentative EQS (= 1000 ng/l) adopted by the SW Region, an investigation was undertaken to trace the source of tecnazene and to gain more information about the variation in concentration of this scantly studied pesticide. Three chemical surveys traced the source of tecnazene to a fish and chip shop at Treneere where potato washings are discharged directly to the river. The study demonstrated that discharges are intermittent and that routine river monitoring may miss periods of maximum contamination.
