Pot-culture experiments showed that organically grown Vicia faba, influenced by atmospheric deposition, accumulated (μg g(-1)) 0.088-3.246 Cadmium, 0.19-42.48 Chromium, 0.0124-30.43 Copper, 0.075-4.28 Lead and 0.63-67.68 Zinc. Similar trends appeared for Abelmoschus esculentus. At high deposition sites, Cadmium, Lead and Zinc exceeded the safe limits of Prevention of Food Adulteration standards. Health risk index for Cadmium, Copper and Lead exceeded the safe limits of United States Environmental Protection Agency. The study suggests that atmospheric deposition could substantially elevate metal levels in organically grown vegetables in 2011.
盆栽实验表明，受大气沉降影响，有机种植的蚕豆（Vicia faba）中积累了 0.088-3.246μg/g 的镉、0.19-42.48μg/g 的铬、0.0124-30.43μg/g 的铜、0.075-4.28μg/g 的铅和 0.63-67.68μg/g 的锌。蕹菜（Abelmoschus esculentus）也呈现出类似的趋势。在高沉降点，镉、铅和锌超过了《防止食品掺假法》的安全限量标准。镉、铜和铅的健康风险指数超过了美国环境保护署的安全限量标准。研究表明，大气沉降可能会使 2011 年有机种植蔬菜中的金属含量大幅上升。
