“…In urban environments, other risk factors of birth defects may prevail, including exposure to other environmental chemicals such as pesticides different than those used in field crops or rural activities. The relationship observed in the rural microregions is of particular concern taking into account that, although agricultural workers in the South and Southeast Region of Brazil might have a higher risk perception from pesticide exposure [31,32] compared to other regions, it has been shown that knowledge and awareness of pesticide risks do not always lead to safety practices among Brazilian farmers [33,34]. Moreover, lower pesticide risk perception has been shown among women in agricultural population in Brazil [20,34], which may lead to a higher pesticide exposure even during pregnancy.…”

Objectives: To investigate the association between per capita pesticide consumption and infant mortality rates from CNS and CVS congenital malformations in microregions in the South and Southeast Region of Brazil. Material and Methods: An ecological study was conducted using data on pesticide expenditure in 1985 and 1996, and deaths caused by CNS and CVS malformations in infants under 1 year old in 1986-1990 and 1997-2001, respectively. Per capita pesticide consumption and infant mortality rates were calculated for each microregion. Microregions were grouped according to quintiles of pesticide consumption, taking the first quintile as reference. The association between pesticide consumption and infant mortality was examined by calculating Spearman correlation coefficients (r) and mortality rate ratios (RR), stratifying by gender and type of microregion (urban or rural). Results: Significant and positive correlations between per capita pesticide consumption and rates of mortality due to CNS and CVS defects were observed in rural but not urban microregions. In general, mortality RRs for the 2 types of malformations in rural microregions were significantly higher in each quintile of pesticide consumption compared to the lowest quintile in the 2 study periods, with elevations ranging between 10% and 30%. Likewise, mortality RRs in these microregions showed significant trends of increase across quintiles of pesticide consumption in both study periods. In urban areas, however, mortality RRs from both CNS and CVS malformations were weak and not statistically significant, and a trend of increase of mortality with increasing pesticide usage was not observed. Conclusions:The results show the relevance of pesticide exposure in rural areas with intense agricultural activity, suggesting that such prenatal exposures may be related with the occurrence of certain congenital defects.

“…Organophosphates are used extensively in agriculture in different regions of Brazil (Faria et al, 2009;Stroparo;Braguini, 2011;Pasiani et al, 2012;Ribeiro et al, 2012), probably due to the large number of brands still available on the market and factors such as low cost and traditional use by farmers (Lima et al, 2011).…”

“…However, information such as efficiency, dosage, application intervals, persistence, and confidence interval is available only for crops in conventional cultivation and are scarce for protected cultivation (Vida et al, 2004). Occupational exposure to pesticides may be prolonged and intensified by environmentally specific conditions in protected cultivation such as high temperature, high humidity, and poor ventilation (Jurewicz et al, 2009;Ribeiro et al, 2012). Furthermore, as protected cultivation requires intensive care, workers are exposed more frequently to pesticides, especially those dispersed in confined areas (Siebers;Mattusch, 1996).…”

“…Furthermore, as protected cultivation requires intensive care, workers are exposed more frequently to pesticides, especially those dispersed in confined areas (Siebers;Mattusch, 1996). Despite this fact, there are few studies in this regard and, in Brazil, there are no specific guidelines or regulations for greenhouse activities (Ribeiro et al, 2012).…”

RESUMO:Os inseticidas organofosforados estão entre os agrotóxicos de maior toxicidade aguda disponíveis no mercado e são usados em várias regiões do Brasil. Avaliaram-se a concentração e o tempo de permanência do inseticida organofosforado clorpirifós no ar, após aplicação em uma casa de vegetação. O clorpirifós permaneceu no ar da casa de vegetação em concentração três vezes acima do limite de exposição ocupacional por mais de 24 horas, e ainda foi detectado após quatro dias. PALAVRAS-CHAVE: inseticidas organofosforados, exposiçãoocupacional, período de reentrada. ABSTRACT:Organophosphate pesticides are among those with the highest acute toxicity and are available on the market and used in several regions of Brazil. The concentration and residence time of the organophosphate pesticide, chlorpyrifos, in the air after application in a greenhouse were investigated. For more than 24 h, the chlorpyrifos remained in the greenhouse air at concentrations three times above the occupational exposure limit and was still detectable four days later.

“…Exposure to pesticides in agriculture is mainly through dermal and inhalation contact (IPCS, 2004), and use of personal protective equipment (PPE) may help reduce exposure levels (IPCS, 2004;Blanco and al 2005). Studies to determine knowledge, attitudes and practices (PAC) on the use of pesticides have been conducted around the world to understand the working environments and conditions in which pesticides are handled and applied by agricultural workers (Ngowi and al 2002;Recena and al 2008;Ospina and al 2009, Karunamoorthi 2011, Ribeiro 2012. The harmful effects of pesticides are divided into two categories: acute toxicity and chronic effects.…”

Pesticides including organophosphates (OPs) and carbamates are used extensively in public health and agriculture to increase crop yields. The abuse of pesticides can have a serious impact on farmer's health. The objective of this study is to study changes in serum cholinesterase activity (BChE) as a biological marker of PO poisoning. Workers in a palm tree oil unit during periods of exposure and non-exposure to pesticides, as well as a control group were selected randomly. The clinical signs reported are those observed in the subjects exposed to organophosphates and anticholinesterase carbamates. The serum enzymatic activity (AES) of cholinesterase was quantified by spectrophotometry. The average serum cholinesterase level during the exposure and non-exposure period was 4225.64 U / l ± 791.10 and 4766.47 ± 873.32 versus 6588.95 U / l ± 1303, respectively, 42 the control level (n = 43) (p <0.001). The average enzymatic activity of workers (n = 19) during non-exposure and exposure periods increased from (78.95%) to non-exposure (36.84%) (Data Not shown) with a significant difference (p = 0.00750). Inhibition of enzymatic activity greater than 40% was observed during the non-exposure phase in 21.05% of cases, and during the exposure period in 26.32% of cases, a bi-annual biological factor necessary for these workers.
