Abstract

The purpose of this research work is to evaluate the degree of eight heavy metals (Fe, Mn, Cu, Zn, Cd, Pb, Cr, and Ni) contamination and health risks of three regularly consumed vegetables (papaya, bottle gourd, and esculent) near one of Bangladesh's busiest roadways, the Dhaka-Mymensingh highway. The heavy metal concentrations in 45 vegetable samples were analyzed using an atomic absorption spectrometer (AAS). These samples were collected from five different sampling sites based on various land use patterns adjacent to the highway. The average concentrations (mg/kg) of Cu, Fe, Mn, Zn, Cr, and Ni were found to be 9.86, 246.8, 16.9, 28.0, 9.02, and 2.02, respectively, for papaya; 14.9, 281.2, 387.6, 49.0, 10.1, and 2.92, respectively, for bottle gourd; and 17.6, 183.4, 107.2, 80.7, 7.98, and 2.34, respectively, for esculent. The mean concentrations of Cr, Zn, and Mn in papaya, bottle gourd, and esculent were higher than the acceptable limit. Correlation analysis revealed a significant positive correlation between Fe-Cu, Zn-Fe, Cu-Fe, and Fe-Zn in papaya; Cu-Zn, Fe-Cr, Zn-Ni, and Cr-Fe in bottle gourd; and Mn-Cr, Mn-Ni, Mn-Fe, and Cr-Ni in esculent, thereby indicating their common anthropogenic sources like agricultural activities, waste from the commercial area, filling station, and vehicular emissions. Health risk assessment through target hazard quotient (THQ) revealed the highest THQ of 9.52 for Cr in bottle gourd, which poses a high non-carcinogenic health risk to the localities upon the intake of these contaminated vegetables. Target cancer risk (TCR) was found to be highest for Cr in papaya (0.013) and bottle gourd (0.014). TCR trends were found for Cr in the following order: bottle gourd > esculent > papaya. This study contributed the greatest concern for both carcinogenic and non-carcinogenic health impacts through ingesting contaminated vegetables.

摘要

本研究工作的目的是评估孟加拉国最繁忙的道路之一——达卡-迈门辛高速公路附近三种常见食用蔬菜(木瓜、葫芦和食用蔬菜)中八种重金属(铁、锰、铜、锌、镉、铅、铬和镍)的污染程度及健康风险。使用原子吸收光谱仪(AAS)分析了45个蔬菜样品中的重金属浓度。这些样品是根据高速公路附近不同的土地利用模式从五个不同的采样点采集的。木瓜中铜、铁、锰、锌、铬和镍的平均浓度(mg/kg)分别为9.86、246.8、16.9、28.0、9.02和2.02;葫芦中分别为14.9、281.2、387.6、49.0、10.1和2.92;食用蔬菜中分别为17.6、183.4、107.2、80.7、7.98和2.34。木瓜、葫芦和食用蔬菜中铬、锌和锰的平均浓度高于可接受限值。相关性分析表明,木瓜中铁-铜、锌-铁、铜-铁和铁-锌之间存在显著正相关;葫芦中铜-锌、铁-铬、锌-镍和铬-铁之间存在显著正相关;食用蔬菜中锰-铬、锰-镍、锰-铁和铬-镍之间存在显著正相关,从而表明它们有共同的人为来源,如农业活动、商业区废物、加油站和车辆排放。通过目标危害商数(THQ)进行的健康风险评估显示,葫芦中铬的THQ最高,为9.52,摄入这些受污染蔬菜会对当地居民造成较高的非致癌健康风险。发现木瓜(0.013)和葫芦(0.014)中铬的目标癌症风险(TCR)最高。铬的TCR趋势如下:葫芦>食用蔬菜>木瓜。本研究对通过摄入受污染蔬菜造成的致癌和非致癌健康影响最为关注。
