Cadmium in agricultural soils, vegetables and rice and potential health risk in vicinity of Dabaoshan Mine in Shaoguan, China

Cadmium contamination of rice from various polluted areas of China and its potential risks to human health

“…1. Industrial activities such as mining and smelting are one of most important sources of Cd contamination (Li et al 2009;Wang et al 2014). Therefore, five provinces where Cd contamination is mainly caused by mining and smelting were included in this study.…”

“…Other confounding factors including age, diet, lifestyle, history of diseases, and economic status may also be related to Cdinduced health risks. Recent studies have reported that rice from the vicinity of mining and smelting sites such as villages near the Dabaoshan mine in Shaoguan, Guangdong, were contaminated by Cd, thereby causing a significant health risk to local communities Wang et al 2014). Environmental heavy metal pollution markedly increased the accumulation of Cd in the crops of vicinity of these areas, which poses significant health risks for the local residents.…”

“…Huang et al (2013) reported that the mean Cd intake level of 0.037 mg·kg −1 among residents of Zhejiang, China, did not exceed the maximum allowable concentration (MAC) of 0.2 mg·kg −1 in the national standard of China, and the assessment in the mean levels indicated no health risk. Cd concentrations in rice obtained in areas within the vicinity of mining and smelting sites were higher than Cd MAC and posed a significant health risk to the population even in mean levels Wang et al 2014). Given the high rice consumption and the serious Cd pollution in many areas in China today (MEPC 2013), investigating the Cd contamination of rice and its health risk certainly deserve more research attention.…”

Modest amendment of sewage sludge biochar to reduce the accumulation of cadmium into rice(Oryza sativa L.): A field study

“…The safety of rice production plays an important role in the social and economic development of China. In some area of China, including Guangdong and Hunan, Cd concentrations, particularly in paddy soils, have become elevated due to the mining activities and the use of mining wastewater in field irrigation (Zhai et al, 2008;Wang et al, 2014). Rice produced under these circumstances has been shown to have greater accumulation of Cd and as a consequence consumption of this 'tainted' rice results in much greater exposure to Cd (Simmons et al, 2005;Meharg et al, 2013).…”

Phyto-Microbial Degradation of Glyphosate in Riyadh Area

“…Phytoremediation has been defined as the use of green plants and their associated micro-organisms, soil amendments and agronomic techniques to remove contain or render harmless environmental contaminants [14,15]. Phytoremediation increases soil organic carbon, soil bacteria, and mycorrhizal fungi, all factors that encourage degradation of organic chemicals in soil.…”
