Determinação de pesticidas organoclorados em água de manancial, água potável e solo na região de Bauru (SP)

Abstract: Recebido em 6/10/03; aceito em 2/3/04; publicado na web em 17/6/04 DETERMINATION OF ORGANOCHLORATED PESTICIDES IN THE WATER SUPPLY SYSTEM, DRINKING WATER AND SOIL OF THE REGION OF BAURU (SP). This paper evaluates the presence of organochlorinated pesticides in the water supply system of the city of Bauru, State of São Paulo, Brazil. Soil samples were collected in agricultural areas and water samples at several points of the water source (river) and the distribution net. The results of the analyses of the water… Show more

“…[8][9][10] A cromatografia gasosa (GC; Gas Chromatography) com a utilização do detector por captura de elétrons (ECD; Electron Capture Detection) ou acoplado à espectrometria de massas (MS; Mass Spectrometry) é relatada como uma técnica bem definida para análise de organoclorados. 11 A exatidão e a precisão na análise de pesticidas depende do preparo da amostra (extração e pré-concentração) e da performance do instrumento.…”

“…Various techniques have been used for the extraction of pesticide residues in aqueous matrices, such as liquid-liquid extraction and solid-phase extraction (SPE). [8][9][10] Although efficient techniques are known, appropriate adaptation is needed in order to reduce the volume of organic solvents and the analysis time.…”

“…Solid-phase microextraction is simple and fast, therefore, the technique has been applied for the determination of micro-pollutants, including non-volatile and volatile organic compounds, phenolics, polycyclic aromatic hydrocarbons, and pesticides. 11,12 The application of SPME for retention of pesticides has been reported in various matrices including soil, 8 food, 13,14 river water, 15 rain water, 16 raw and treated water, 17 groundwater 18,19 and aqueous matrizes. [20][21][22][23][24][25][26] The technique consists in the extraction of analytes using a silica fiber coated with a layer of sorbent, which is exposed directly in the sample or in the headspace.…”

“…Studies on pesticide occurrence in environmental samples from the tropics are increasing [4][5][6][7] but still focus mainly on organochlorine pesticides, 8 which have been banned in most countries during the last decades. 4 As air and soil temperatures are higher in tropical than in temperate regions, an increased pesticide loss to the atmosphere by volatilization has to be expected, 4 as well as by biodegradation.…”
