AbstractEstimating exposure to phthalate plasticizers is crucial to perform appropriate risk assessment and develop control measures. In this study, we analyze wastewater to estimate the exposure to six phthalates within thirteen Spanish cities. Composite daily samples were collected over four consecutive days in Spring 2018 at seventeen wastewater treatment plants serving ca. 6 million people. Concentrations of phthalate metabolites were converted into population-normalized loads and used to estimate (i) metabolite levels in urine, and (ii) values of daily exposure to the parent phthalates. Population-weighted means of the estimated concentrations in urine varied between 0.7 ng/mL and 520 ng/mL. Compared to human biomonitoring data, very high levels were obtained for monomethyl phthalate, metabolite of dimethyl phthalate. This fact, together with literature data pointing to other sources of this metabolite in sewage led to its exclusion for exposure assessment. As for the remaining metabolites, results obtained on a local scale revealed the butylated phthalates as the ones posing the highest concern, particularly for toddlers. On a national scale, including all the sampled sites, di-(2-ethylhexyl) phthalate accounted for the highest percentage of total risk, followed closely by diethyl phthalate and di-iso-butyl phthalate.
