Environmental Risk Limits for Alkylphenols andAlkylphenol ethoxylates

摘要

In this report Environmental Risk Limits (ERLs) are derived fornonylphenol, octylphenol 1+2 ethoxylate (OPEO1+2), octylphenol 3-8ethoxylate (OPEO3-8), octylphenol >8 ethoxylate (OPEO>8), nonylphenol 1+2ethoxylate (NPEO1+2), nonylphenol 3-8 ethoxylate (NPEO3-8), nonylphenol>8 ethoxylate (NPEO>8), carboxylated octylphenol 1+2 ethoxylate (OPE1+2C)and carboxylated nonylphenol 1+2 ethoxylate (NPE1+2C). The derived ERLswere shown to be protective for endocrine effects of these compounds,based on the in vivo effect studies available. Nearly all ERLs for soiland sediment were calculated from ERLs for the aquatic environment usingequilibrium partitioning theory because soil and sediment toxicity datawere virtually absent. Recent (1999, 2001) measurements of nonylphenolor nonylphenol ethoxylates in the Netherlands in rivers, estuaries andsediments showed slight exceedance of the maximum permissibleconcentration (MPC) in some cases.
