“…Single samples of Cd in wheat and traces of Cd in barley were detected [19]. According to literature data on cereals, higher values of Pb are found in rice, followed by Cd, especially in rice imported from China, India and Pakistan [20]. Cereals were consumed in the recommended amounts by the study participants and the results obtained for Pb and Cd content, except for rice, would not be likely contributors to heavy metal exposure.…”

Purpose of the study is to investigate food consumption in young people and the contribution of food to heavy metal pollution. Methods: The object of the study are 60 healthy young people aged 19-29 years (average age – 23,9 ± 2,6) from Pleven and the Pleven district. Assessment of food intake was made according to A two-day, 24-hour diet recall method and Food Frequency Questionnaire (FFQ) method. A documentary method was used to assess the content of heavy metals- data provided by the Food Chain Risk Assessment Centre Data provided by the Food Chain Risk Assessment Centre. 2,471 food samples were analyzed for lead and cadmium over a 7-year period. Result: The food group importing complex carbohydrates could have a probable contribution to the dietary exposure to Pb and Cd, as they are consumed in the recommended amounts, although no content of lead and cadmium above the maximum permissible amounts was found in the studied foods. Intake of vegetables and fruits is significantly below recommended - vegetables and fruits would likely contribute to dietary exposure to Pb and Cd provided they were consumed as recommended. The average daily intake of dairy products is compared to the references. Game meat and offal could contribute to dietary exposure to both heavy metals, but these were also not consumed by the respondents. Fish and seafood likely contribute to dietary exposure to heavy metals, but their consumption is low and significantly below recommendations. Conclusion: The obtained results confirm the importance of a healthy food model for the protection of human health, including protection from chemical hazards in food.

“…Despite the cessation of mining for 20 years, local environmental Hg levels (in soil, water, and rice) are still evidently higher than the standard limitation ( 6 ). The concentrations of Hg are 1.3 ~ 360 mg/kg in local topsoil variation, 13 ~ 2,100 ng/L in water, and 6.0 ~ 113 in rice ng/g ( 22 , 23 ). Different from Wuchuan, Hg and other heavy metals are within safe thresholds in Anshun ( 24 , 25 ).…”

ObjectiveMercury (Hg) contamination in the environment around mercury mines is often accompanied by heavy metal contamination.MethodsHere, we determined concentrations of chromium (Cr), zinc (Zn), strontium (Sr), barium (Ba), and lead (Pb) in duck eggs from a Hg mining area in Southwest China to assess the contamination and health risk.ResultsDuck eggs obtained from the mining area exhibit higher concentrations of Cr, Zn, Sr, Ba, and Pb compared to those from the background area, with egg yolks containing higher metal levels than egg whites. Specifically, the mean Cr, Zn, Sr, Ba, and Pb concentrations of duck eggs from the Hg mining area are 0.38, 63.06, 4.86, 10.08, and 0.05 μg/g, respectively, while those from the background area are only 0.21, 24.65, 1.43, 1.05, and 0.01 μg/g. Based on the single-factor contamination index and health risk assessment, heavy metal contamination in duck eggs poses an ecological risk and health risk.ConclusionThis study provides important insight into heavy metal contamination in duck eggs from Hg mining areas.

“…Huang 12 reported that Cd and As were the major non-carcinogenic and carcinogenic factors in rice from Hubei, China. Li 13 reported that Cd, Cu, Zn, and Ni had a different spatial contamination pattern in rice, and that Pb and Cd were the main health risk 14 . In addition, higher than the acceptable level (1 × 10 −6 ) for the carcinogenic risk of As was found in rice samples from Iran 15 , but Takamoto A 16 found that Cd and As in milled rice grown in Japan, Vietnam, and Indonesia do not pose a non-carcinogenic health risk, and same result by Bielecka 17 .…”

Pigmented and non-pigmented rice varieties (grown in different areas) were collected in China, Yunnan, to investigate the content of macro-, trace elements and potentially toxic elements (PTEs), and to assess the health risk associated with dietary intake. The order of elemental concentrations in rice was Mn > Zn > Fe > Cu > Se for trace elements, P > K > Mg > Ca > Na for macro elements, and Cr > As > Cd for PTEs. Rice with a high concentration of essential elements also associated with a high content of PTEs. In addition, higher content of Cr, Mn and Na were found in pigmented rice. The health risk assessment showed that the daily intake of all elements was below the tolerable limit (UL). Moreover the intake of Fe, Zn and Se was far from sufficient for the nutrient requirement. The PTEs in rice dominated the health risk. Of concern is that this rice consumption is likely to contribute to carcinogenic risks in the long term and that adults are at higher health risk from pigmented rice compared to non-pigmented rice. This study confirms that the lack of essential micronutrients in rice and the health risk associated with rice diets should remain a concern.
