Additional information

Should read > 100 mg/L. No toxic effects against algae were observed at a limit test concentration of 100 mg/L. The results are expressed in terms of Effective Loadings (EL). As the test item is a multi constituent and no information about the correlation between molecular weight and the structural formula of the test item are available, a Water Accommodated Fraction (WAF) was used to test effects at a limit concentration of 100 mg/L, and no specific analysis was performed. With the sponsor’s agreement, the content of the test item during the exposure period was verified by DOC determination.
