In recent years, there is an increasing trend to consume organic foods instead of the conventional foodstuffs. This tendency is mainly due to the concern raised by the potential adverse health effects derived from the intake of pesticides, fertilizers, hormones and antibiotics, which are widely used in regular food production. Although organic label forbids the use of these products, environmental contamination is likely to occur in both, conventional and organic foodstuffs. The main purpose of this review was to compare the levels of a number of environmental pollutants such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), mycotoxins, trace elements, polycyclic aromatic hydrocarbons (PAHs), etc., in organic and conventional food items. The results show that, in general, the presence of nearby anthropogenic sources of pollution is the key issue influencing the occurrence of environmental pollutants in foodstuffs, regardless their organic or conventional origin. Based on this, we suggest that environmental contaminants should be monitored in both conventional and organic foods. Finally, the safety feature, which has been globally attributed to organic foods, might be questionable depending on the potential environmental contamination of these foods.
近年来，人们越来越倾向于选择有机食品而不是传统食品。这种趋势主要是由于人们担心摄入农药、化肥、激素和抗生素等广泛用于常规食品生产的物质会对健康产生潜在的不利影响。尽管有机标签禁止使用这些产品，但常规食品和有机食品都可能受到环境污染。本综述的主要目的是比较有机和常规食品中一些环境污染物的水平，如多氯二苯并对二恶英和二苯并呋喃（PCDD/Fs）、多氯联苯（PCBs）、霉菌毒素、微量元素、多环芳烃（PAHs）等。结果表明，一般来说，附近人为污染源的存在是影响食品中环境污染物发生的关键因素，而不论其是有机还是常规来源。基于此，我们建议对常规食品和有机食品进行环境污染物监测。最后，由于这些食品可能受到潜在的环境污染，因此全球归因于有机食品的安全特性可能值得质疑。
