Priorization of aquatic emerging contaminants from São Paulo State

Abstract

The United Nations Environment Programme and the World Health Organization classifies as essential and urgent knowledge of the sources, transformations and fate of emerging contaminants in the environment due unequivocal evidence about numerous observed effects to wild populations, as well as possible damages observed in humans. These are thousands of chemicals that are present in the environment and may cause risks to the intended uses of water. The prioritization of these substances is essential to the beginning of the regulatory process, whether for prevention or control of input. Brazil, due to their socioeconomic and environmental amplitude, is a country that has environmental problems similar to developed countries, while that magnifies problems typical of areas with fragile economies such as the serious problems associated with poor of sanitation. This scenario is further aggravated in São Paulo due to the water crisis now ravaging virtually the entire state, and whose consequences involve socioeconomic, environmental and public health problems. This scenario is aggravated in São Paulo State due to the water crisis that currently include all State, and whose consequences involve socioeconomic, environmental and public health problems. This project aims to prioritize compounds of relevance to surface and drinking waters, for this, will be developed and validated an analytical method using SPE and LC MS/MS for determination of 80 different contaminants (pharmaceuticals, personal care products, industrial compounds, natural and synthetic estrogens, pesticides) in nanogram per liter levels in about 200 samples from different water sources and drinking waters from the State of São Paulo, collected monthly for a period of one year. The occurrence data will be compared with the water quality criteria for different uses of water, obtaining a list of priorities contaminants for the State of São Paulo, which would subsidize public policies that contribute to ensuring the source water quality, and thus the water destined for human consumption.
