The recently derived Dutch Environmental Quality Standards (EQS) for water, soil, and sediment for approximately 170 substances have been evaluated. Three methods have been used to derive the Dutch EQS. Independent of how the EQS were derived, they are given equal weight in Dutch environmental policy. Scientifically, the three methods may deserve different weights. For example, for soil and sediment, the least reliable method had to be applied to derive most of the EQS. Ecological effects in these compartments may be either overestimated or underestimated. A multitiered approach is proposed, which is relevant for all parties involved, including other countries, and which may help improve ecological effect assessment.
近期制定的荷兰针对约170种物质的水、土壤和沉积物环境质量标准（EQS）已得到评估。推导荷兰EQS采用了三种方法。无论EQS是如何推导出来的，它们在荷兰环境政策中具有同等权重。从科学角度来看，这三种方法可能应赋予不同权重。例如，对于土壤和沉积物，在推导大多数EQS时不得不采用最不可靠的方法。这些介质中的生态效应可能被高估或低估。本文提出了一种多层方法，这对包括其他国家在内的所有相关方都具有相关性，并且可能有助于改进生态效应评估。
