摘要

1 Introduction Diuron is a phenylurea herbicide that has been frequently detected in surface waters (the US Environmental Protection Agency, USEPA 2003), including periods when relatively low amounts were used, because it is moderately persistent in the water column (Ensminger et al. 2008). Diuron poses a risk to aquatic life because it, and other herbicides, can cause adverse effects on algae and vascular plants, which are the foundation of the aquatic food chain. Water quality standards are used to regulate pesticides in surface waters, and these standards are typically based on water quality criteria for the protection of aquatic life. When pesticide concentrations do not exceed water quality criteria, no adverse effects on aquatic life are expected. The derivation of acute and chronic water quality criteria for diuron using a new methodology developed by the University of California, Davis (TenBrook et al. 2010), is described in this chapter. The UC Davis methodology (UCDM) was designed to be more flexible than the USEPA method (1985) for deriving water quality criteria, although many aspects of the methods are similar.
