The aim of the present work was to report on the occurrence of contaminants and trace elements in organically grown commercial cereal products, available in the Greek market. Moreover, the level of contamination of domestic organic cereals was compared with that of imported ones. To this end, the level of contamination by heavy metals (Pb, Cd), nitrates, trace elements (Cu, Fe, Mn, Zn, Cr, Ni, Co) and mycotoxins (aflatoxins, deoxynivalenol, zearalenone, ochratoxin, and T-2) were reported. Seventy-six organic cereals and derived products of domestic and imported origin were tested including rice, barley, oat, wheat, maize and two samples made of a mixture of grains. The levels of contamination were calculated and compared to the recommended or regulated maximum levels. The maximum levels were exceeded for lead (2), cadmium (1), aflatoxins (4), and ochratoxin (1). Contamination of samples by nitrate was below the allowed level. The level of contamination in domestic organic samples was similar to that of imported ones, except for cadmium with imported samples being more contaminated. The findings of this study are important in terms of risk to human health, but they do not support nor reject the hypothesis that organic cereals are less contaminated than the conventional ones.

希腊市场出售的有机谷物商业食品中存在霉菌毒素,重金属和硝酸盐残留

本工作的目的是为了对污染物的发生报告和微量元素的有机种植的商业谷物产品,可在希腊市场上购买。此外,还比较了国内有机谷物和进口有机谷物的污染水平。为此,重金属(Pb,Cd),硝酸盐,微量元素(Cu,Fe,Mn,Zn,Cr,Ni,Co)和霉菌毒素(黄曲霉毒素,脱氧雪茄烯醇,玉米赤霉烯酮,曲毒素和T- 2)报道。测试了76种国内和进口的有机谷物和衍生产品,包括大米,大麦,燕麦,小麦,玉米以及两种由谷物混合物制成的样品。计算出污染水平,并将其与建议的或规定的最大水平进行比较。铅(2),镉(1),黄曲霉毒素(4)和曲毒素(1)的最高含量被超过。硝酸盐对样品的污染低于允许的水平。国内有机样品的污染水平与进口有机样品相似,但镉的污染程度更大,进口样品受到的污染更大。这项研究的发现对人类健康具有重要意义,但它们既不支持也不反对有机谷物污染程度低于传统谷物这一假设。
