分析了来自纽约市和纽约州布法罗花园的成对蔬菜/土壤样本中的铅（Pb）、镉（Cd）和钡（Ba）。测定植物铝（Al）以评估土壤粘附性。土壤和蔬菜的金属浓度没有相关性，蔬菜浓度因作物类型而异。几乎所有水果的铅含量都低于健康指导值（欧盟标准）。47%的块根作物和9%的绿叶蔬菜超过指导值;超过一半的蔬菜超过了市场篮子铅浓度的第95百分位数。蔬菜铅与铝，土壤颗粒粘附/掺入更重要的是通过根吸收铅。镉是类似的市场篮子浓度和指导值以下，几乎所有的样品。蔬菜中Ba含量远高于Pb和Cd，而土壤中Ba含量低于Pb。蔬菜和土壤金属浓度之间的关系不佳是由于颗粒污染的蔬菜和土壤特性，影响植物的有效性。
Paired vegetable/soil samples from New York City and Buffalo, NY, gardens were analyzed for lead (Pb), cadmium (Cd) and barium (Ba). Vegetable aluminum (Al) was measured to assess soil adherence. Soil and vegetable metal concentrations did not correlate; vegetable concentrations varied by crop type. Pb was below health-based guidance values (EU standards) in virtually all fruits. 47% of root crops and 9% of leafy greens exceeded guidance values; over half the vegetables exceeded the 95th percentile of market-basket concentrations for Pb. Vegetable Pb correlated with Al; soil particle adherence/incorporation was more important than Pb uptake via roots. Cd was similar to market-basket concentrations and below guidance values in nearly all samples. Vegetable Ba was much higher than Pb or Cd, although soil Ba was lower than soil Pb. The poor relationship between vegetable and soil metal concentrations is attributable to particulate contamination of vegetables and soil characteristics that influence phytoavailability.
