摘要

The work presented in this paper is related to the identification of the pressures on surface water bodies, as a result of diffuse pollution from the Plant Protection Products (PPPs) used during the agricultural activity in Greece. The pressures are quantified and expressed as loads from the PPPs' active substances that enter surface water bodies by implementing the methodology presented by the FOrum for the Co-ordination of pesticide fate models and their Use (FOCUS Surface Waters). The methodological approach and its implementation have been conducted in the framework of the Switch-On project.A database of loads to surface waters, for the most common active substances of PPPs in Greece, has been developed through the use of numerical simulations in accordance to the methodology presented by the FOCUS Surface Waters group for establishing relevant Predicted Environmental Concentrations in surface water bodies. The database includes 15 different active substances which were identified as the most significant for Greece. Two out of ten sets of modelling parameters scenarios, developed by the FOCUS SW group as a series of standard agriculturally relevant scenarios for the European Union, were used. The relevancy of these scenarios was estimated to be more than 30% for the Greek agricultural conditions, reaching up to 56% under certain conditions. According to the simulation results, all runoff scenarios resulted to less than 1% of the substance applied to the plants entering surface waters, whereas drainage could result up to 9%. On average, the percentage of a substance that reaches the surface waters is of the order of 1% of the quantity applied, when the drainage scenarios are implemented. In the case of runoff, the amount is lower and does not exceed, on average values, 0.3%. Although drift is a small transport component as to the total amount of substance transported into surface waters, it can result to greater concentrations in the water body than drainage or runoff.
