为了评估重金属引起的潜在健康风险,根据达卡的年龄和吸烟状况,从塑料行业工人那里收集了26份血液样本。孟加拉国。用原子吸收光谱仪分析重金属。铅(Pb)的平均浓度,镉(Cd),镍(Ni),暴露工人的血液样本中发现的锌(Zn)分别为32.78±9.47、1.08±0.47、1.42±1.01和9.08±1.95μgL-1。吸烟工人的血液样本中的平均重金属浓度比非吸烟工人的波动范围窄。对不同年龄段的行业工人的审查显示,年龄在26至40岁之间的工人更容易受到Pb(35.90±8.06μgL-1)和Ni(1.61±1.31μgL-1)的污染。在>40岁的工人中发现较高的Cd(1.26±0.46μgL-1)和Zn(9.91±2.80μgL-1)。不同工业分区的室内粉尘样品中Pb的平均浓度为40.27±10.33、3.24±0.83、18.08±3.61和103.64±8.16mgkg-1,Cd,Ni,Zn,分别。从平均每日摄入量(ADI)得出的结论是,暴露的工人对健康的影响相对较小,危险商(HQs),和危险指数(HI)值。Pb的HI值,Cd,Ni,和锌分别为2.0×10-2、4.64×10-4、1.62×10-3和5.49×10-4,这给工人的健康带来了最小的风险(如HI<1)。铅的癌症风险,Cd,和Ni分别低于阈值为1.46×10-10、1.77×10-9和1.31×10-9。因此,与1×10-6~1×10-4的EPA限值相比,暴露的产业工人的癌症风险可能较低.
To assess the potential health risk caused by heavy metals twenty-six blood samples were collected from plastic industry workers based on ages and smoking status in Dhaka, Bangladesh. Heavy metals were analyzed with an atomic absorption spectrometer. The mean concentrations of Lead (Pb), Cadmium (Cd), Nickel (Ni), and Zinc (Zn) found in blood samples of the exposed workers were 32.78 ± 9.47, 1.08 ± 0.47, 1.42 ± 1.01, and 9.08 ± 1.95 μgL-1, respectively. The average heavy metal concentrations in blood samples of smoking workers show a narrow range of fluctuation than that of non-smoking workers. A review of different age groups of industry workers shows the workers between the ages of 26 and 40 are more likely to contaminated with Pb (35.90 ± 8.06 μgL-1) and Ni (1.61 ± 1.31 μgL-1). The higher level of Cd (1.26 ± 0.46 μgL-1) and Zn (9.91 ± 2.80 μgL-1) was found in >40 years old workers. The mean concentration in indoor dust samples of different industrial subsections reported as 40.27 ± 10.33, 3.24 ± 0.83, 18.08 ± 3.61, and 103.64 ± 8.16 mg kg-1 for Pb, Cd, Ni, and Zn, respectively. Exposed workers have relatively less critical health implications concluded from the average daily intake (ADI), hazard quotient (HQs), and hazard index (HI) values. The HI values of Pb, Cd, Ni, and Zn were reported as 2.0 × 10-2, 4.64 × 10-4, 1.62 × 10-3, and 5.49 × 10-4, respectively, which have imparted minimal risks (as HI < 1) to the health of the workers. The cancer risks of Pb, Cd, and Ni were reported as 1.46 × 10-10, 1.77 × 10-9, and 1.31 × 10-9, respectively lower than the threshold values. Therefore, the result divulged a potentially lower cancer risk compared to EPA limit value of 1 × 10-6 to 1 × 10-4 for exposed industrial workers.
