Conteúdo: 	A method based on Hasse diagrams is adopted to detect priority pesticides among the 130 most used in Europe. Hasse diagrams rank pesticides in groups of potential hazard to the water environment, according to pesticide properties (water solubility, vapour pressure and persistence in soil) and usages. The procedure is applied on a terretorial scale, selecting Germany, U.K and Italy as case studies and validated with the experimental results of monitoring programs. Most of the pesticides ranked as a first priority by the model and analyzed for in water were effectively found. The percentage of positive findings decreases from class 1 to 6 of priority in agreement with the theoretical predictions. The model suggests that each contry must develop its own analytical protocoladdressed to the detection of the most problable pesticides. Pesticide metabolities of Italian priority pesticides are appraised in detail and their risk is assessed according to the their occurance in surface and groundwater, persistence estimated from field data an ecotoxicity data. The proposed procedure can steer research efforts towards compounds that really represent a risk for human health and aquatic life.
