One of cadmium's major exposure routes to humans is through rice consumption. The concentrations of cadmium in the global polished (white), market rice supply-chain were assessed in 2270 samples, purchased from retailers across 32 countries, encompassing 6 continents. It was found on a global basis that East Africa had the lowest cadmium with a median for both Malawi and Tanzania at 4.9 μg ...
A total of 484 rice samples were collected from five polluted areas in China to investigate the cadmium (Cd) contamination of rice and its potential health risks. The mean Cd contents of analyzed rice samples obtained from different areas ranged from 0.149 to 0.189 mg·kg−1. Cd concentrations in more than 18 % of rice samples exceeded the maximum allowable Cd concentration, and the highest ...
Environmental exposure to cadmium causes renal dysfunction and bone damage. Cadmium contamination in food is regarded as the main environmental source of non-occupational exposure. The aim of this study was to assess the contribution of dietary cadmium exposure in environmental cadmium exposure and its health risk among adults in Shanghai, China.

The trophic transfer and bioaccumulation of Cd through progression of the food chain has widely been studied around the world, such as China, UK, Jamaica, etc [5,15,17,22]. For example [ 17 ], in their study in Chenzhou City (Southern China) found 0.01–4.43 mg/kg of Cd concentrations in rice plants grown near mining areas.
"Cadmium rice" is a well-known term in China since a Guangdong province government report last year that 44 per cent of rice samples had excessive levels of cadmium attracted attention.
China, South Korea, and Japan are the leading producers of cadmium in the world, followed by North America. Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body's cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.

Cadmium is a heavy metal of considerable environmental and occupational concern. It is widely distributed in the earth's crust at an average concentration of about 0.1 mg/kg. The highest level of cadmium compounds in the environment is accumulated in sedimentary rocks, and marine phosphates contain about 15 mg cadmium/kg .
Mercury, cadmium, and lead concentrations of ashed plants and insects samples were investigated and compared with those of soil to reveal their biogeochemical processes along food chains in Huludao City, Liaoning Province, China. Concentration factors of each fragments of the soil-plant-the herbivor …

It crystallizes in the monoclinic space group P 2 1 / c, and its structure features an interesting {[TePO 6 ] 3– } ∞ chain constructed by corner-sharing connected PO 4 and TeO 4 tetrahedra. Meanwhile, we obtained a new phase of Cd 3 (PO 4 ) 2 and Cd 1.725 Mg 1.275 (PO 4 ) 2 in the exploration of tellurite-phosphates, and they also ...
Soil contamination in some areas of southern China has resulted in elevated dietary intake of cadmium (Cd), posing a potential risk to human health. A survey of paired soil-rice (n = 200) and soil-vegetable (n = 142) samples was conducted in Xiangtan county of Hunan province, southern China. The con …
China's Cadmium-Tainted Rice Scandal. The news, reported by Xinhua, that rice believed grown in China's Hunan province contains unacceptable traces of cadmium, is the latest scandal to beset the country's food chain and probably means imports will have to rise sharply to meet the shortfall. China had already emerged as the second-largest ...
For China's low-cost jewelry-makers, it was an open trade secret: The metal cadmium is shiny, strong and malleable at low temperatures, regardless of its health hazards. And it's cheap.
