In this paper, the distribution of mercury (Hg) in agricultural soil and biological material (chard, cabbage, kale, moss and tree bark) collected from agricultural plots in Sarajevo, Bosnia and Herzegovina (B&H), was monitored. The method of atomic absorption spectrometry-cold vapor technique (CVAAS) was used for Hg analysis. By concentrations of Hg, all samples were arranged as the following diminishing series: soil > moss > chard > kale > cabbage > bark. Very strong correlation of Hg in cabbage, chard and kale was obtained, with correlation factor above 0.950. Bioconcentration factors (BCF) for plant materials were all below 1. The degree of Hg soil contamination ranged from the category of clean, unburdened soil to the category of Hg-contaminated soil. Human exposure to Hg through soil and vegetable consumption was also estimated. Contributor that most impacts the health risk is the ingestion followed by the dermal and inhalation pathways for both, children and adults. The probable weekly intake (PWI) values were all below 1 μg/kg body weight, suggesting that there is no potential health risk to the local residents.

土壤-植物系统中汞的人类健康风险评估

在本文中,监测了从波斯尼亚和黑塞哥维那萨拉热窝 (B&H) 的农田收集的农业土壤和生物材料(甜菜、卷心菜、羽衣甘蓝、苔藓和树皮)中汞 (Hg) 的分布。使用原子吸收光谱-冷蒸气技术(CVAAS)方法进行汞分析。根据汞浓度,所有样品按以下递减系列排列:土壤>苔藓>甜菜>羽衣甘蓝>卷心菜>树皮。卷心菜、甜菜和羽衣甘蓝中汞的相关性很强,相关系数在 0.950 以上。植物材料的生物富集系数(BCF)均低于 1。汞土壤污染程度从干净、无负担的土壤类别到汞污染土壤类别不等。还估计了人类通过土壤和蔬菜摄入而接触到的汞。对健康风险影响最大的因素是摄入,其次是儿童和成人的皮肤和吸入途径。每周可能摄入量 (PWI) 值均低于 1 μg/kg 体重,表明对当地居民没有潜在的健康风险。
