Resumo(s)
This study modeled the impact on freshwater ecosystems of pharmaceuticals detected in biosolids following
application on agricultural soils. The detected sulfonamides and hydrochlorothiazide displayed
comparatively moderate retention in solid matrices and, therefore, higher transfer fractions from biosolids
to the freshwater compartment. However, the residence times of these pharmaceuticals in freshwater
were estimated to be short due to abiotic degradation processes. The non-steroidal anti-inflammatory
mefenamic acid had the highest environmental impact on aquatic ecosystems and warrants further
investigation. The estimation of the solid-water partitioning coefficient was generally the most influential
parameter of the probabilistic comparative impact assessment. These results and the modeling approach
used in this study serve to prioritize pharmaceuticals in the research effort to assess the risks and the
environmental impacts on aquatic biota of these emerging pollutants.
