Milieurisicogrenzen voor alcoholen, glycolen en enkele andere relatief oplosbare of vluchtige stoffen. 2. Integratie van risicogrenzen voor mens en ecosystemen

Environmental risk limits are concentrations of a substance in water, air, sediment and soil that are expected to be protective of the environment. In this report environmental risk limits (ERLs) are derived, based on a comparison of human and ecotoxicological risk limits. Ecotoxicological risk limits, derived previously, were compared to risk limits for human health for the following substances: 1-butanol, n-butyl acetate, cyclohexylamine, diethylene glycol, ethylene glycol, ethyl acetate, methanol, methyl ethyl ketone (MEK), methyl tert-butyl ether (MTBE), tribromomethane and triethanolamine. The lowest value (human health or ecosystems) determines the final risk limit of a substance. Environmental risk limits based on ectoxicological information were calculated in part 1 of this report (RIVM report 601501016). The scientific basis for the human risk evaluation model Humanex is described in a companion report (RIVM report 601501022).
