abstract
Emerging micropollutants are substances found in the environment in very low concentrations, as micrograms or nanograms per liter, but that can cause harmful effects even in these low quantities. Since this is a recent issue, these pollutants are not legislated yet, but depending on the results of toxicity, bioaccumulation and other studies, they can be regulated in the future.
The Pharmaceuticals and Personal Care Products (PPCP’s) are a subclass of emerging micropollutants. Although they are very relevant to society, these compounds are eliminated in high quantities by the human body and are not efficiently removed from water in sewage treatment plants. Since they are present in very low concentrations, the analysis and study of PPCP’s is a tough task, demanding sophisticated instrumental methods of analysis.
Therefore, the aim of this study is to develop a method of analysis to quantify and to monitor the concentration of some PPCP´s, such as, ibuprofen, diclofenac, naproxen, sulfamethoxazole, azithromycin and carbamazepine in aqueous media from Bragança region. These were the pharmaceutical drugs chosen since they are compounds most likely to be found in the aqueous matrices of the area.
