Avaliação dos níveis de pesticidas organoclorados em águas na região de Apucarana-PR usando a microextração em fase líquida com cromatografia gasosa acoplada à espectrometria de massa

Abstract

The environment is constantly changing, mainly due to human influence. Environmental monitoring has object to environment, predict future damage and remedy potential impacts. Surface water is a dynamic medium, with constant changes and increasing demand, requiring quality assurance for their use, performed by physical-chemical, microbiological and analysis compounds traits. In this study, surface water samples of 12 different points of the city of Apucarana, Paraná (Brazil), were collected within one year. The samples were subjected to physical, chemical and microbiological analyzes, analyzed based on chemometrics in order to demonstrate the influence of urban and rural areas, and the most important factors to characterize the environment. Considering the influence of rural environments were analyzed the presence of organochlorine pesticides in the optimization of the method of liquid-liquid microextraction dispersive, and instrumental use of gas chromatography-mass spectrometry. Data indicates that the environments are free from contamination and within the acceptable standards for both the physical-chemical and microbiological parameters. The environments of interest also presented free of contamination by organochlorine pesticides in the research period.
