“…The concentration of DMA was also associated with tAs (r = 0.644, p < 0.01). These phenomena conform with our previous study (Ma, Wang, Jia, & Yang, 2016) and other reports (Zhao, Zhu, & Meharg, 2013;Zhu et al, 2008). Besides concentration, the percentages of As(III) and DMA were used to investigate correlation with tAs.…”

“…Arsenic in mine-affected vineyard soils in Italy ranged from 4 – 283 mg/kg and positive correlations were observed between soil concentrations and arsenic levels in vine leaves and grapes, however, levels in wine were low (< 1.62 μg/L) 47 . In the Hunan province, China, the high levels of inorganic arsenic in rice have been traced to mining activities in the area 48–50 .…”

This review is on arsenic in agronomic systems, and covers processes that influence the entry of arsenic into the human food supply. The scope is from sources of arsenic (natural and anthropogenic) in soils, biogeochemical and rhizosphere processes that control arsenic speciation and availability, through to mechanisms of uptake by crop plants and potential mitigation strategies. This review makes a case for taking steps to prevent or limit crop uptake of arsenic, wherever possible, and to work toward a long-term solution to the presence of arsenic in agronomic systems. The past two decades have seen important advances in our understanding of how biogeochemical and physiological processes influence human exposure to soil arsenic, and this must now prompt an informed reconsideration and unification of regulations to protect the quality of agricultural and residential soils.

“…Moreover, high concentrations of potentially toxic metals such as Cd, Pb and As was found in edible mushrooms in China (Liu et al, 2015). Even rice shows high concentrations of Pb and As, which represents carcinogenic health risks (Omar, 2015, Ma et al, 2016. Products derived of plants also can transfer heavy metal to human body.…”

Heavy metal contamination in soils is a major environmental concern that affects large areas worldwide. Agricultural practices have been the main source of heavy metals in soil such as lead, chromium, arsenic, zinc, cadmium, copper and nickel. Plants can uptake this toxic metals and have evolved defense mechanisms to avoid or minimize damages. Exposure to toxic metals can intensify the production of reactive oxygen species (ROS), which are continuously produced in both unstressed and stressed plants cells. Some of the ROS are highly toxic and must be detoxified by cellular stress responses, if the plant is to survive and grow. Heavy metals contaminated plants cause losses in crop production and risks for human health. Thus, this review aims to compile some information about research work on concentration of heavy metals until they reach the food chain for transferring to crops.Additional keywords: agriculture; contamination; heavy metals; reactive oxygen species. ResumoA contaminação de solos por metais pesados é um grande problema ambiental que afeta várias regiões do mundo. As práticas agrícolas é uma das principais fontes de contaminação de metais pesados no solo, como chumbo, cromo, arsênio, zinco, cádmio, cobre e níquel. As plantas podem absorver estes metais tóxicos, com isso desenvolveram mecanismos de defesa para evitar ou minimizar danos. A exposição a metais pesados pode aumentar a produção de espécies reativas de oxigênio (EROs) que são continuamente produzidas em plantas sob estresse ou em condições normais. Algumas desta EROs são altamente tóxicas e devem ser detoxificadas por respostas celulares ao estresse, possibilitando a sobrevivência e crescimento do vegetal. A contaminação de vegetais por metais pesados causam perdas na produtividade agrícola e riscos para a saúde humana. Assim, esta revisão tem o objetivo de unir informações sobre como os metais pesados chegam aos solos e afetam a nutrição e fisiologia com reflexos na produção agrícola.Palavras-chave adicionais: agricultura; contaminação; espécies reativas de oxigênio; metais pesados.
