A Survey of Copper Concentrations in Vegetables and Soils in Guilin and the Potential Risks to Human Health
摘要
Abstract
In order to assess the potential human health risk posed by elevated concentrations of copper in vegetables, a large scale survey of copper levels in soil and vegetables planted or sold in Guilin was conducted. One hundred and sixty soil samples were collected from fields used to grow vegetable plants. In addition, 566 fresh vegetable samples were obtained from vegetable production fields and vegetable stalls. Copper concentrations in soils ranged from 11.69 to 348.8 mg· kg-1, with median, arithmetic and geometric means of 27.41, 34.62 mg· kg-1 and 29.43 mg · kg-1, respectively. Compared with the background copper concentrations of soil from Cuilin, there was no significant accumulation of copper in soil collected from vegetable plots. Copper concentrations in the edible plant portions was 0.032~3.530 mg·kg-1 fresh weight, with median and geometric means of 0.321 and 0.325 mg·kg-1 fresh weight, respectively. In all of the samples and vegetable varieties, copper was less than the tolerance limit of copper in foods of 100 mg·kg-1 fresh weight for pulse and 20 mg· kg-1 for other vegetables. Compared with the copper concentrations of vegetables in other area, the copper concentrations of vegetables in Guilin at the lower level. The average inges-tion rate of copper from vegetables was 1.01 mg·individual-1·d-1 for people of Guilin, and it's make up 5.6% of the quantity demanded( 18 ing·individual-1·d-1) and 1.85% of No-Observed-Adverse Effect-Level(NOAEL), Consuming vegetables with elevated copper concentrations may no) pose a health risk to local residents.关键词
