ABSTRACT

Some heavy metals were detected in organs of the tomatoes grown in the discharge area of effluents of a municipal wastewater treatment plant. Also, the health risk potentials of heavy metals in the tomatoes consumed by human were investigated. The highest concentrations for Cu, Ni, Cr, Mn and Pb were followed the order of root>leaf>stem>fruit. When the bioconcentration factors values calculated for bioconcentration of metals from effluent to stem and root were examined, the highest values were determined for Cu. When translocation factors values are examined, the highest translocation from root to leaf was determined for Cd. The highest translocation from stem to leaf was determined for Pb. The estimated total exposure dose for male, female and children was listed as Zn>Mn>Cu>Cr>Ni>Pb>Cd. In terms of dietary, we can list the non-carcinogenic risks of heavy metals as children> female> male. The highest carcinogenic risk was calculated for Cr via dietary intake.

摘要

某市政污水处理厂污水排放区种植的番茄器官中检测到一些重金属。此外，还调查了人类食用的西红柿中重金属的潜在健康风险。Cu、Ni、Cr、Mn、Pb的最高浓度依次为根>叶>茎>果实。当检查从流出物到茎和根的金属生物富集计算的生物富集因子值时，确定了铜的最高值。当检查易位因子值时，确定了镉从根到叶的最高易位。从茎到叶的最高易位被确定为铅。男性、女性和儿童的估计总暴露剂量为 Zn>Mn>Cu>Cr>Ni>Pb>Cd。在饮食方面，我们可以将重金属的非致癌风险列为儿童>女性>男性。通过膳食摄入计算出 Cr 的最高致癌风险。
