“…For decades, the pattern of pesticide usage in agriculture industry has steadily increased both globally and simultaneously with the rise of population growth to meet the demands of food production (Caldas et al, 2011). Almost 30% global pesticide are from developing countries (Caldas et al, 2011) with Malaysia alone consuming more than 200000 tons pesticide annually comprising of more than 50000 tons of active compounds (Sabere et al, 2013). Pesticides are also classified into different classes depending on its purpose or target organism, and this includes herbicide, insecticide, fungicide, nematicide, and bactericide (Mohd Fuad et al, 2012).…”

For decades, the percentage of pesticide usage has steadily increased in order to meet the demands of food production. The aim of this study is to estimate the risk posed towards farmers through exposure to surface water containing imazapic herbicide using dermal exposure assessment (DEA). For this purpose, hazard index (HI) value was calculated to estimate the risk posed towards the farmers. Although calculated HI showed a minimum level of risk, there are concerns toward the danger of long-term exposure to the farmers of an agricultural system that could affect their quality of life.Keywords: Dermal exposure assessment; farmers; imazapic; hazard indexeISSN 2398-4279 © 2018.

“…Consequently, according to Pelaez, Terra and Silva (2010) there is a conflict of interests due to the ability of regulators, regulated companies and the companies themselves in adapting to the more stringent criteria for registering toxic substances (PELAEZ; TERRA; SILVA, 2010; GONÇALVES, 2016). There are studies that prove the contamination caused by the indiscriminate use of pesticides in different regions of Brazil (ALBUQUERQUE et al, 2016;ZANELLA;PRIMEL, 2011;RISSATO et al, 2007;CALDAS et al, 1999;ALHO;VIEIRA, 1997); however, this gap between Brazilian and state legislation leads to a panorama of uncertainties about the extent and degree of environmental contamination, as well as the dimension of effects to the human health and to the environment. Since there are no equal control procedures throughout the national territory, there are vulnerabilities associated with the use of agrochemicals.…”

Brazil is the third largest market and the eighth largest consumer of pesticides per hectare in the world, with herbicides and insecticides accounting for 60% of the products traded in the country. The use of pesticides has increased worldwide in the last decades, which may represent a risk for several diseases in humans, including cancer. Although in Brazil the research on the impact of the use of pesticides on human health has grown in recent years, it is still insufficient to really know the real dimension of health damage caused mainly by occupational and food exposure, due to the intensive use of pesticides. This article aims to review the use of pesticides by rural workers in Brazil, highlighting the importance of preventive measures for their health.

“…Penoxsulam, propanil and 2,4-D show different classifications by the US-EPA and GUS methods, or due to the lack of physicochemical parameters the prediction was not possible. These differences between the methods can occur because they consider different physicochemical characteristics (Caldas et al, 2011).…”
