The report presents a study on the environmental behaviour of melamine (CAS: 108-78-1), investigated in adsorption and desorption experiments with five different soils.
As part of the study, the organic carbon-normalized adsorption coefficients (Koc values) were determined. Koc describes the relative distribution of a substance between soil and water, normalized to the fraction of organic carbon in the soil. Under the CLP Regulation, Koc is a key parameter for evaluating the mobility of substances in the aquatic environment, and thus provides an essential basis for environmental hazard classification.
The results of this study deliver important data for assessing melamine with respect to its classification in the regulatory hazard categories PMT (persistent, mobile, toxic) and vPvM (very persistent, very mobile).
