摘要

根据产品授权中使用的沥滤液中的模拟浓度，开发并验证了一种简单有效的启发式方法，用于预测地下水和饮用水资源中农药非相关代谢物（nrM）的浓度。对 50 nrM 大量监测数据的评估表明，启发式方法具有很高的预测性能，即在 1 米深土壤非饱和带浅层沥滤液中 10 µg/l 的浓度在 98% 的情况下（49/50 nrM）可保护地下水和原水不超过 1 µg/l。启发式方法之所以具有出色的预测能力，是因为从沥滤液到地下水和原水的浓度衰减很大，平均分别为 25 倍和 45 倍。

A heuristic approach to attenuation of non-relevant metabolites in groundwater and drinking water in Germany

A simple and effective heuristic approach was developed and validated to predict the concentration of non-relevant metabolites (nrM) of pesticides in groundwater and drinking water resources based on the simulated concentrations in leachate as used in product authorizations. The evaluation of extensive monitoring data for 50 nrM has demonstrated that the heuristic has a high predictive performance, i.e., concentrations of < 10 µg/l in shallow leachate in the unsaturated zone of the soil in 1 m depth are protective of 1 µg/l in groundwater and raw water in 98 % of cases (49/50 nrM). The reason for the excellent predictive power of the heuristic approach is the large concentration attenuation from leachate to groundwater and to raw water, which was determined to be, on average, 25- and 45-fold, respectively.

期刊介绍： The JCF publishes peer-reviewed original Research Articles and Opinions that are of direct importance to Food and Feed Safety. This includes Food Packaging, Consumer Products as well as Plant Protection Products, Food Microbiology, Veterinary Drugs, Animal Welfare and Genetic Engineering. All peer-reviewed articles that are published should be devoted to improve Consumer Health Protection. Reviews and discussions are welcomed that address legal and/or regulatory decisions with respect to risk assessment and management of Food and Feed Safety issues on a scientific basis. It addresses an international readership of scientists, risk assessors and managers, and other professionals active in the field of Food and Feed Safety and Consumer Health Protection. Manuscripts – preferably written in English but also in German – are published as Research Articles, Reviews, Methods and Short Communications and should cover aspects including, but not limited to: · Factors influencing Food and Feed Safety · Factors influencing Consumer Health Protection · Factors influencing Consumer Behavior · Exposure science related to Risk Assessment and Risk Management · Regulatory aspects related to Food and Feed Safety, Food Packaging, Consumer Products, Plant Protection Products, Food Microbiology, Veterinary Drugs, Animal Welfare and Genetic Engineering · Analytical methods and method validation related to food control and food processing. The JCF also presents important News, as well as Announcements and Reports about administrative surveillance.
