Pharmaceutical and personal care products (PPCPs) are being increasingly included in Life Cycle Assessments (LCAs) since they have evidenced ecological and human adverse effects and due to their presence in different environmental compartments, wastewater facilities and industry. Therefore, the main goal of this research was to estimate characterization factors (CFs) of 27 PPCPs widely used worldwide for incorporating these values in LCIA studies or to generate impact score rankings. Physicochemical properties, degradation rates, bioaccumulation, ecotoxicity and human health effects were collected from experimental data, recognized databases or estimated by EPI SuiteTM. USEtoxTM software was used for estimating CFs. An impact score ranking was done for 49 PPCPs using the new CFs calculated and the CFs already available and besides the data of PPCPs occurrence in the environment in Spain. Emission to continental freshwater compartment showed the highest CFs for human effects (ranging on 10-9 to 10-3), following by air (10-9 to 10-5), soil (10-11 to 10-5) and sea water (10-12 to 10-4). CFs of the affectation of freshwater aquatic environments were the highest from emission to continental freshwater (between 1 to 104) due to the direct contact between the source of emission and the compartment affected, followed by soil (among 10-1 to 104), air (among 10-2 to 104) and the lowest were continental sea water CFs (among 10-28 to 10-3). Freshwater aquatic ecotoxicological CFs are much higher than human toxicity CFs which involves that ecological impact of PPCPs in aquatic environments is a matter of urgent attention …
