“…However, considering the size of the country and the total amounts of pesticides applied, the number of studies describing pesticides in surface water [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] and in ground water [16][17][18][19][20][21][22][23][24][25] is not large. Most of these studies have examined organochlorine pesticides, most of which have been banned in Brazil since the 1980s, except for endosulfan, which will be prohibited beginning in 2013.…”

Este estudo fornece dados sobre a presença dos pesticidas atrazina, clorpirifós, a-endossulfam, β-endossulfam, flutriafol, malatiom e metolacloro em água de áreas urbanas e rurais das cidades de Campo Verde e Lucas do Rio Verde, no estado do Mato Grosso, Brasil. Amostras de água superficial, de chuva e subterrânea foram coletadas nas estações de seca e chuva em 2007 e 2008 nessas importantes áreas produtoras de grãos. Os resultados revelaram maior diversidade de substâncias e frequência de detecção em amostras de água de chuva. Concentrações de atrazina, endossulfam e malatiom foram encontradas acima dos níveis permitidos pela legislação brasileira em algumas amostras de água superficial e subterrânea, e os metabólitos DIA (de-isopropil-atrazina) e endossulfam sulfato foram encontrados em níveis maiores do que os compostos parentais em algumas amostras. Nossos resultados demonstram a vulnerabilidade dos recursos hídricos nessas áreas e apontam para o risco de contaminação de áreas de nascentes de importantes córregos por pesticidas.This study provides data on the presence of the pesticides atrazine, chlorpyrifos, a-endosulfan, β-endosulfan, flutriafol, malathion and metolachlor in water matrices in urban and rural areas of Campo Verde and Lucas do Rio Verde Cities, Mato Grosso State, Brazil. Surface, rain, and groundwater samples were collected in the rainy and dry seasons during 2007 and 2008 in these important grain-producing areas. The findings revealed a higher diversity of compounds and frequency of detection in the rain water than in surface and groundwater samples. Concentrations of atrazine, endosulfan and malathion above those permitted by Brazilian regulations were found in some surface and groundwater samples, and the degradation products DIA (deisopropylatrazine) and endosulfan sulfate, rather than their parental compounds, were found at higher levels in some samples. Our findings show the vulnerability of water systems in these areas and point to the risk of pesticide contamination in important headwater streams.

1 Quais agrotóxicos estão contaminando os solos brasileiros?Which pesticides are contaminating a brazilian soils? ¿Qué agrotoxicos contaminan los suelos brasileños? ResumoOs pesticidas têm uma importante função dentro da sociedade, entretanto seu uso excessivo pode causar problemas para a saúde do ambiente. Dentre estes problemas, a contaminação do Research, Society and Development, v. 9, n. 3, e114932569, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i3.2569 2 solo por agrotóxicos tem sido pouco discutida, fato preocupante, pois a qualidade do solo está relacionada diretamente ao funcionamento ecológico, a produção primária e a saúde humana.A contaminação do solo por agrotóxicos depende de diferentes fatores como os edáficos, propriedades do solo e da substância. O uso de agrotóxicos tem sido alvo de diferentes discussões mundiais, entretanto, estas discussões no cenário brasileiro tornam-se ainda mais necessárias devido ao vasto consumo e aplicação destas substâncias no país. Esta revisão apresenta uma visão crítica quanto a contaminação do solo por agrotóxicos dentro do território brasileiro utilizando como ferramentas o calculo do quociente de risco e comparação entre os valores de referência para solo canadenses e brasileiros. Vale ressaltar que apenas 12 unidades federativas brasileiras tinham dados disponíveis sobre concentrações de pesticidas em solos reais brasileiros (Amazonas, Bahia, Maranhão, Mato Grosso, Minas Gerais, Pará, Paraná, Rondônia, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, São Paulo). Os pesticidas mais detectados no solo e em maiores concentrações foram o Diclorodifeniltricloroetano, Hexaclorociclohexano e Hexaclorobenzeno. Em geral, os locais de estudo possuíam cenários de exposição com particularidades e não estavam relacionados ao atual uso de agrotóxicos no país. Neste contexto, é enfatizado a importância de estudos adicionais sobre resíduos de pesticidas em solos brasileiros. Palavras-chave: Monitoramento ambiental; Pesticidas; Defensivos agrícolas; Terra. AbstractPesticides play an important role within society, but their overuse can cause problems for the health of the environment. Among these problems, soil contamination by pesticides has been little discussed, a matter of concern, since soil quality is directly related to ecological functioning, primary production and human health. Soil contamination by pesticides depends on different factors such as soil, soil and substance properties. The use of pesticides has been the target of different worldwide discussions, however, these discussions in the Brazilian scenario are even more necessary due to the vast consumption and application of these substances in the country. This review presents a critical view of soil contamination by pesticides within the Brazilian territory using as tools the calculation of the risk quotient and comparison between the reference values for Canadian and Brazilian soil. It is noteworthy that only 12 Brazilian federative units had data available on pesticide concentrat...

“…One of the soil samples was classified as Udorthent Eutrophic, predominantly sandy, and the other as Chernosol Argiluvic Orthic and Ultisol Dystrophic soil, mostly clayey. They found soil samples with pH in the range of 3.87 to 4.50, which is considered high acidity for soil [24].…”

Technological advances have promoted improvements in several science fields, especially related to environmental and analytical areas with the improvement of detection and development of environmentally friendly extraction techniques. This study applied Quick, Easy, Cheap, Effective, Rugged and Safe method (QuEChERS) for soil extraction and assessed its performance through a validation study using samples from the soil of a contaminated area in Caieiras, SP, Brazil. Nine organochlorine pesticides, including the isomers alpha, beta, gamma and delta- hexachlorocyclohexane; cis- and trans-heptachlor epoxide; cis- and trans-chlordane and heptachlor were analyzed by gas chromatography coupled to electron capture detector. The method was validated according to ISO 5725-4 (2020), EURACHEM (2014) and DOQ-CGCRE-008 (2016). The limits of detection and quantification of the method for the nine organochlorines were α-HCH (1.2 and 12.6 µg kg−1), β-HCH (1.7 and 12.0 µg kg−1), γ-HCH (1.5 and 11.6 µg kg−1), δ-HCH (0.8 and 11.6 µg kg−1), heptachlor (1.0 and 10.8 µg kg−1), cis-heptachlor epoxide (0.9 and 11.5 µg kg−1), trans-heptachlor epoxide (0.9 and 11.5 µg kg−1), cis-chlordane (0.4 and 7.9 µg kg−1) and trans-chlordane (0.5 and 10.9 µg kg−1), respectively, and all of them were within the maximum limits recommended by the EPA for the compounds α-HCH (86.0 and 360.0 µg kg−1), β-HCH (300.0 and 1.3 × 103 µg kg−1), γ-HCH (570.0 and 2.5 × 103 µg kg−1), δ-HCH (not defined), heptachlor (130.0 and 630.0 µg kg−1), cis-/trans-heptachlor epoxide (7.0 and 330.0 µg kg−1), cis-/trans-chlordane (1.77 × 103 and 7.7 × 103 µg kg−1) in residential and industrial soil, respectively. Recovery results were between 65% and 105% for almost all compounds, which is an optimum result for multi-residue analytical methods, considering the complexity of the matrix used in the study. Caieiras presented contamination levels of α-HCH in the range of 2.0 to 66.0 µg g−1, which was higher than the limits established by EPA, corresponding to 0.077 µg g−1 for residential soil and 0.27 µg g−1 for industrial soil. According to the validation study, the analytical method proposed was reliable for organochlorine quantification, and the QuEChERS was considered efficient for organochlorine extraction from soil.
