“…Studies of rice in other countries have shown Cd levels ranging between N.D. and 0.07 mg/kg (Alam et al 2002 ; Gorbunov et al 2003 ; Jorhem et al 2008 ; Phuong et al 1999 ; Shimbo et al 2001 ; Wolnik et al 1985 ). In Japan, rice is a major source of Cd intake for general Japanese populations.…”

Cadmium (Cd) is a toxic pollutant that is widely spread through industrial production and agricultural practices. Epidemiological data has revealed that lifetime exposure to environmentally relevant levels of Cd increases the risk of developing various organ diseases, including chronic kidney, heart, and lung diseases, as well as nervous tissue disorders. This study assessed Cd levels in rice to determine the health risks associated with rice consumption in various age-gender subgroups in Taiwan. The distribution of Cd concentration, the lifetime average daily dose (LADD), and the hazard index (HI) were estimated by Monte Carlo simulation. In the general population, the 50th percentile LADD of Cd for male rice consumers between the ages of 19–65 years was 0.06 μg/kg body weight per day, and the hazard index (HI) 50th, 90th, and 95th percentiles were 0.16, 0.69, and 1.54, respectively. According to the HI heat map for the exposure of the general population to Cd from rice in Taiwan, the highest exposure to Cd was noted in the Yilan area (HI 0.64). Therefore, rice production in the Yilan area should be further monitored to evaluate the levels of Cd contamination.

“…Because of its high mobility in soil, the bioaccumulation of cadmium in plant‐based food is usually high compared to the other trace elements (Lebeau and others ; Satarug and others ; Cui and others ; Azizur and Hiroshi ). According to various surveys from different countries, the range of cadmium concentrations in rice was <0.006 to 0.01 μg/g, depending on the cadmium concentration in the soil or the differences between plant genotypes in cadmium uptake (Jung and Thornton ; Phuong and others ; Shimbo and others ; Alam and others ; Gorbunov and others ; Cui and others ; Lin and others ; Jorhem and others ). A high amount of cadmium (0.9 to 2.5 μg/g) has been reported in mushrooms from the eastern Black Sea (Tuzen and others ).…”

Toxic elements such as mercury, arsenic, cadmium, and lead, sometimes called heavy metals, can diminish mental and central nervous system function; elicit damage to blood composition as well as the kidneys, lungs, and liver; and reduce energy levels. Food is considered one of the main routes of their entry into the human body. Numerous studies have been performed to examine the effects of common food processing procedures on the levels of toxic elements in food. While some studies have reported negative effects of processing, several have shown that processing practices may have a positive effect on the reduction of toxic elements in foodstuffs. A number of studies have also introduced protocols and suggested chemical agents that reduce the amount of toxic elements in the final food products. In this review, the reported methods employed for the reduction of toxic elements are discussed with particular emphasis on the chemical binding of both the organic and inorganic forms of each element in various foods. The molecular groups and the ligands by which the food products bind with the metals and the types of these reactions are also presented.

“…Comparable results were reported by Shimbo et al (2001), Lin et al (2004) and Jorhem et al (2008) with means of 0.002 and 0.016 ppm, respectively. Others have, however, reported much higher levels: Jahed Khaniki and Zazoli (2005) reported a mean level of 2.23 ± 18 ppm dry weight, Al-Saleh and Shinwari (2001) reported a mean level of 0.135 ppm, Gorbunov et al (2003) reported a mean of 1.58 ppm, Bennet et al (2000) reported a mean for wild rice as 0.96 ppm and Alam et al (2002) found a mean as high as 7.71 ppm dry weight (range 2.60–15.89). Such high Pb levels are remarkable, considering that the rice samples were not reported as coming from contaminated areas.…”

“…No sample exceeded the MAC. Several studies on rice carried out in recent years have found slightly lower or similar levels of Cd, ranging between <0.006 and 0.09 mg/kg (Afshar et al, 1995; Alam et al, 2002; Gorbunov et al, 2003; Jorhem et al, 2008; Lin et al, 2004; Liu et al, 2007; Phuong et al, 1999; Shimbo et al, 2001; Wolnik et al, 1985). Regarding the information in previous literature about Iran, Falahi et al (2010) and Afshar et al (1995) reported Cd concentrations with the means of 0.07 ppm and 0.09 ppm for the Iranian type rice.…”

The aim of this study was to investigate the cadmium (Cd) and lead (Pb) content of several commercially available brands of rice grains (Oryza sativa) in central Iran. A total of 67 samples of the most widely consumed brands of rice grains were purchased from local bazaar markets in Shahrekord, Iran. The first step, grains of raw rice were digested by acid digestion method and then were analyzed by atomic absorption spectrometer. The results showed that Cd concentration in rice grains ranged from 0.0378 to 0.1225 ppm dry weight and its average concentration was 0.062 ± 0.019 ppm and Pb content ranged from 0.0405 to 0.1281 ppm dry weight and its average concentration was 0.068 ± 0.0185 ppm. Cd and Pb concentrations in the sampled rice grains were lower in comparison with their upper limits (0.2 and 0.2 ppm for Cd and Pb, respectively) approved by food sanitary standard. Therefore, it can be concluded that there is no health problems due to the consumption of brands of rice grains, for these two elements. The results indicated that weekly intake of Cd and Pb from rice grains was below the provisional tolerable weekly intakes recommended by WHO/FAO.
