Abstract

Cadmium (Cd) and chromium (Cr), as nonessential elements, are considered as very important pollutants, which greatly affects human health. To reduce food chain risk for vegetable soils contaminated by Cd, and/or Cr, the pot experiments were conducted to investigate Cd or Cr uptake by 9 cultivars of familiar leaf vegetables and to screen leaf vegetables with lower Cd or Cr content in Hainan Province. The results showed that the leaf Cd or Cr contents of 8 vegetables were lower than national limit of contaminants in foods under the treatments of 0.61 mg/kg Cd and 3.07 mg/kg Cd. Only for Lactuca sativa var. longifoliaf, Cd accumulation (fresh weight, 0.2275 mg/kg) exceeded the limit of Cd (0.2 mg/kg) under the treatments (3.07 mg/kg Cd and 104 mg/kg Cr). About Cr accumulation, all tested vegetables were lower than national limit of Cr (0.5 mg/kg). Considering the yield and Cd content (fresh weight), Brassica rapa ssp. chinensis (181.5 g, 0.0172 mg/kg) has the greatest advantage. Brassica pekinensis (11.824 g, 0.0204 mg/kg), Brassica campestris ssp. chinensis 328 (11.8 g, 0.0129 mg/kg) and Lactuca sativa var. ramose (8.2 g, 0.0144 mg/kg) have also the relative advantage.

Cr/Cd污染对海南省蔬菜品种的影响
镉(Cd)和铬(Cr)作为非必需元素,被认为是非常重要的污染物,极大地影响着人类的健康。为降低蔬菜土壤Cd、Cr污染的食物链风险,采用盆栽试验研究了海南省9个常见叶菜品种对Cd、Cr的吸收情况,筛选了Cd、Cr含量较低的叶菜品种。结果表明,8种蔬菜在0.61 mg/kg Cd和3.07 mg/kg Cd处理下,叶片Cd或Cr含量均低于国家食品污染物限量,只有长叶莴苣的Cd积累量(鲜重0.2275 mg/kg)在3.07 mg/kg Cd和104 mg/kg Cr处理下超过了Cd限量(0.2 mg/kg)。在Cr积累方面,所有蔬菜均低于Cr国家限量(0.5 mg/kg)。从产量和Cd含量(鲜重)两方面考虑,对油菜品种进行了改良。紫草(181.5 g, 0.0172 mg/kg)优势最大。北京芸苔(11.824 g, 0.0204 mg/kg);中国草芥328 (11.8 g, 0.0129 mg/kg)和芥花(8.2 g, 0.0144 mg/kg)也具有相对优势。
