The impact values for the environmental emissions of 52 solvents are estimated and expressed in monetary units. The impact values of solvents present in the air are calculated on the basis of 13 impact indicators and additional 2 impact indicators for solvents present in water. These impact values are weighed with the results obtained with a multi-compartment distribution model, allowing the calculation of the fraction of solvent emitted to the environment present in each of the compartments. The results show that the impact values of solvent emissions are in the range of 0.7–1179.51 $ L−1, with a mean value of 20.69 $ L−1, expressed in USD2019. These impacts are considerably lower for short-chain aliphatic hydrocarbons, alcohols, ethers, aldehydes, ketones, and esters. High impact values are obtained for long-chain aliphatic hydrocarbons, aromatic hydrocarbons, terpenes, and an extremely high value for carbon tetrachloride. Monetary values calculated to assess the solvent emission impact have the advantage that they are quantitative and easily applicable.

溶剂排放的货币价值估算

对52种溶剂的环境排放的影响值进行了估算,并以货币单位表示。空气中存在的溶剂的影响值是根据13种影响指标和另外2种对水中存在的溶剂的影响指标计算得出的。将这些影响值与通过多隔室分布模型获得的结果进行权衡,从而可以计算排放到每个隔室中存在的环境的溶剂分数。结果表明,溶剂排放的影响值在0.7–1179.51 $ L -1范围内,平均值为20.69 $ L -1,以美元2019年表示。对于短链脂族烃,醇,醚,醛,酮和酯,这些影响要小得多。对于长链脂族烃,芳族烃,萜烯,可以获得很高的冲击值,而四氯化碳的冲击值则很高。计算得出的用于评估溶剂排放影响的货币值具有定量且易于应用的优点。
