Interactions of plant zinc and plant species on the bioavailability of plant cadmium to Japanese quail fed lettuce and spinach

Exposure to metal mixtures and human health impacts in a contaminated area in Nanning, China

“…The reason for this difference is unknown; one possible explanation could be the relatively higher intake of Fe, Ca and Pb from vegetables in V2 (Cui et al, 2004). It has been suggested that high Fe, Zn and Ca intake can reduce the body burden of Cd (McKenna et al, 1992;Goyer, 1997;Reeves and Chaney, 2001). One could argue that higher Fe and Ca intake in the present study did not result in a significant increase in levels of S-Fe and S-Ca (Table 1).…”

“…It has been well documented that a number of factors, such as mineral status, play an important role in metal absorption and accumulation in the human body through the food chain (McKenna et al, 1992;Fox, 1988;Smolders, 2001;Chaney et al, 2001;Reeves, 2001;Reeves and Chaney, 2001). In a rat feeding study, Reeves and Chaney (2001) demonstrated that marginal mineral deficiencies in calcium and iron could readily enhance the body burden of Cd from the diet; and other natural competitors of Cd, such as Zn, contained in foods can independently minimize Cd absorption.…”

Heavy Metals, Resting Metabolism Rates and Breeding Parameters in Two Populations of Black-Headed GullLarus ridibundusfrom the Industrially Polluted Areas of Upper Silesia, Poland

“…Laboratory studies with the Japanese Quail gave some opposite results. In birds fed zinc-deficient diet elimination of cadmium from the intestine, liver and kidneys was higher than in birds fed zinc-sufficient diet , McKenna et al 1992. Probably in this situation cadmium replaced zinc in metalloenzymes, however with adverse results.…”

How Does Contamination of Rice Soils with Cd and Zn Cause High Incidence of Human Cd Disease in Subsistence Rice Farmers

“…The interaction between Zn and Cd in rice is clearly an anomaly compared to other foods. In addition, Zn in test diets with food levels of Cd (not the high levels used by most toxicological researchers) limited increase of Cd in kidney and liver even when Cd was significantly increased compared to basal diets [21][22][23][24][25]. At food Cd levels, the co-contamination with Zn significantly reduces crop Cd bioavailability and risk except for rice consumption.…”

“…Research using food levels of Cd has clearly shown that absorption of Cd is inhibited by Zn in the test meal [23][24][25]93] and strongly increased by Fe deficiency status of the individual [94][95][96]. Research by Reeves and collaborators attempted to clarify the role of the nutrient deficiencies of rice subsistence diets in increased Cd absorption [97].…”
