The limit values prescribed by German drinking water regulations for "pesticides and their toxic main metabolites" (PBSM) protect the consumer from imponderable toxicological risks. It therefore complies with the "principle of concern" which is part of several statutory instruments of the FRG to protect ground and drinking water. Moreover, for about 10% of the permissible active ingredients, health-based limit concentrations in drinking water can be derived which are of the same order of magnitude as the legal limit value for PBSM. The main purpose of the "PBSM Recommendation" of the Federal Health Office of July 1989 is to preserve and to restore a pesticide-free ground and drinking water situation mainly by agricultural measures with at the same time maximum possible health protection for the consumers of drinking water. The bureaucratic handling of this "Recommendation" by the Commission of the EC and the standardised pesticide admittance procedure as envisaged by the EC could seriously endanger this purpose. A consequence would be that, as already in the USA, the same situation could arise in Europe that more and more active ingredients are found in ground water in concentrations which are up to 1,000 fold higher than the respective toxicological limit values for drinking water.
德国饮用水法规对“农药及其主要有毒代谢物”（PBSM）规定的限值保护消费者免受难以估量的毒理学风险。因此，它符合“关注原则”，该原则是德意志联邦共和国保护地表水和饮用水的多项法定文书的一部分。此外，对于约10%的允许使用的活性成分，可以得出饮用水中基于健康的限值浓度，其与PBSM的法定限值处于同一数量级。联邦卫生部1989年7月发布的“PBSM建议”的主要目的是主要通过农业措施保持和恢复无农药的地表水和饮用水状况，同时为饮用水消费者提供最大可能的健康保护。欧盟委员会对该“建议”的繁琐处理以及欧盟设想的标准化农药准入程序可能会严重危及这一目标。结果将是，正如美国已经出现的情况那样，欧洲可能会出现越来越多的活性成分在地下水中的浓度比饮用水各自的毒理学限值高出多达1000倍的情况。
