Chemical safety assessment
According to REACH legislation, a chemical safety assessment "has to be performed by registrants for substances manufactured and imported in quantities starting at 10 tonnes per year and by downstream users if their uses are not addressed by their supplier."The CSA includes the evaluation of all...

Measured environmental concentration
An Measured Environmental Concentration relates to a chemical substance found in an environmental sample. The concentration of the compound may result from direct contamination, transformation and/or metabolization of an different chemical contaminant, natural origin or a combination of these...
