Log K_OW = Logarithmic octanol water partition coefficient; BCF = Bioconcentration Factor (L kg⁻¹); B = Bioaccumulative; BAF = Bioaccumulation Factor (L kg⁻¹); BMF = Biomagnification Factor (kg lipid kg lipid⁻¹); BSAF = Biota-Sediment Accumulation Factor (kg organic carbon kg lipid⁻¹); CEPA = Canadian Environmental Protection Act; REACH = European Union Registration, Evaluation, Authorization, and Restriction of Chemicals; N/A = not available; NL = indicates that the B metric is not listed under a regulatory program
