“…The study conducted by Moreira et al, 11 in the 62 samples of water from artesian wells, found the presence of residues of atrazine, metolachlor, chlorpyrifos, apha and beta endosulfan, flutriafol, and permethrin. Remembering that the use of endosulfan was prohibited in the European Union due to its carcinogenic potential.…”

“…Moreira et al 11 suggested the potential of environmental and human contamination by pesticides used in the production of grains and cotton in the state of Mato Grosso, and their impacts on the biota, however, more in depth studies are required to characterize this impact. Studies must also be conducted with this population in the short, medium and long term with the purpose of following-up the evolution of its health, seeking to analyze the increase in or appearance of neoplasias in this group; However, the concentration of cases of epidermoid carcinoma was greater in the municipalities of Cuiabá, Várzea Grande and Rondonópolis, with 50 cases (38.7%), contrary to the hypothesis raised.…”

ObjectiveTo assess the prevalence of epidermoid carcinoma cases, georeference their locations, and seek to correlate them to areas with higher agricultural production and use of pesticides. Methods This was a cross-sectional, descriptive and retrospective study conducted by searching the histopathological reports with confirmed diagnosis of epidermoid carcinoma of the mouth issued from August 2005 to December 2011 by the public oral pathology laboratory of the State of Mato Grosso, Brazil. Data were plotted with the IBM SPSS Statistics software and spatial analysis used the ArcGIS 10.1 software. Results There were a higher number of diagnoses in 2007 (26.6%); 99 cases (75%) of patients were male; 96 cases (72.8%) were patients aged between 41 and 70 years; and the cities of Cuiabá, Várzea Grande and Rondonópolis respectively showed the highest number of occurrences. ConclusionNo relationship was found between the occurrence of cases of epidermoid carcinoma and the municipalities with high agricultural production and pesticide use.

R E S U M OOs pesticidas utilizados na agricultura para combater pragas e doenças têm causado contaminação dos recursos hídricos cujas consequências são alterações nos ecossistemas e prejuízos à saúde, sobretudo quando as águas são utilizadas para consumo humano. A contaminação ocorre principalmente em áreas próximas aos locais de aplicação por deflúvio superficial ou contaminação do lençol freático. Alguns fatores que afetam o transporte para o meio aquático são as propriedades do agente químico e variáveis ambientais, como tipo de solo, declividade, presença de cobertura vegetal e clima; alguns desses fatores, como relevo planáltico e solo quartzoso, estão presentes em grande parte do país fazendo com que a poluição do meio aquático seja acentuada. A adoção de práticas agrícolas mais racionais pelos agricultores e medidas como proteção das matas ciliares, podem prevenir a contaminação por pesticidas dos recursos hídricos, sendo a forma mais eficiente de controle da poluição agrícola nas condições locais.Main aspects of the pollution in Brazilian rivers by pesticides A B S T R A C T Pesticides, which are used in agriculture for pest and disease control, has caused contamination of water resources. The consequences are changes in ecosystems and damage to health, especially when the waters are used for human consumption. The contamination occurs mainly in areas near the application site by surface runoff or groundwater contamination. Some factors affecting transport to the aquatic environment are the properties of the chemical and environmental conditions, such as soil type, slope, land cover and climate. Some factors such as plateau relief and quartzose soil are present in the most part of the country, causing the water pollution more severe. The adoption of more rational agricultural practices by farmers and measures for protection of riparian forests can prevent pesticide contamination of water resources, which consists in the most efficient control practice for agricultural pollution in the tropical regions. Palavras IntroduçãoPesticidas são um dos grupos mais representativos de poluentes no ambiente devido ao seu uso intensivo na agricultura (Choudhury et al., 2008). O Ministério do Desenvolvimento Agrário, MDA (2012) e a Agência Nacional de Vigilância Sanitária, ANVISA (2013) mostram que o Brasil é o maior consumidor e produtor de agrotóxicos do mundo, desde 2009. O mercado desses produtos cresceu aproximadamente 176% na última década sendo quatro vezes maior que a média mundial (ANVISA, 2013).O impacto do aumento da produção de bens agrícolas no ambiente é notado pela perda da biodiversidade e da qualidade dos recursos hídricos. Os estudos de monitoramento de resíduos de agrotóxicos têm aumentado ano a ano e sinalizado que resíduos de agroquímicos estão presentes nos alimentos (ANVISA, 2013), na atmosfera (Moreira, et al., 2012), nas precipitações secas e úmidas, como chuvas (Nogueira et al., 2012) e águas superficiais e subterrâneas .A ocupação desordenada do solo origina a supressão da vegetação compact...

Potential effect of chemical and thermal treatment on the Kinetics, equilibrium, and thermodynamic studies for atrazine biosorption by the Moringa oleifera pods

et al. 2017

View full text Add to dashboard Cite

The effectiveness of chemical and thermal pretreatments on Moringa oleifera pods for the atrazine removal from water was investigated. The untreated pods (MOPun), the chemically treated pods (MOPC), and the chemically treated pods followed by the thermally treated pods (MOPT) were physico‐chemically and morphologically characterized by elemental, pHZPC, N2 physisorption, FTIR, and SEM analysis. The effect of modified pods was significant in increasing surface porosity, favouring the surface chemistry, and improving the atrazine biosorption capacity. Kinetics data were best explained by pseudo‐second order model for all biosorbents. The equilibrium data for biosorption were analyzed by using Langmuir, Freundlich, Sips, and Polanyi‐Manes (PMM) isotherm models to define the best correlation for atrazine biosorption capacity. Among the four isotherm models, both Sips and PMM were the models best fitted with the equilibrium isotherm for atrazine. The maximum atrazine adsorption capacities were 0.629, 1.580, and 7.47 mg · g−1 for MOPun, MOPC, and MOPT respectively with a maximum removal percentage of 65 %, 82 %, and 99 %. The thermodynamic studies showed that atrazine biosorption is favourable. The biosorption experiments demonstrated that Moringa oleifera pods have great potential for removing atrazine and other organic contaminants from water.
