Tobiszewski, Marek | Bystrzanowska, Marta
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.
