Abstract

The non-carcinogenic and carcinogenic health risks arising from potential exposure to heavy metals pose a negative threat to human health. In this study, heavy metals (Hg, As, Cd, Cr, Pb, Ni, Cu, Zn) analyses were conducted in the waters of four creeks in the Mogan Lake Basin (Sukesen Creek, Başpınar Creek, Yavrucak Creek, Gölcük Creek) under anthropogenic pressure. In the water samples taken from the creeks that also contribute to Mogan Lake, which has significant recreational importance in the basin: a) The non-carcinogenic health risks (HQ) of exposure to heavy metals through ingestion and dermal routes were identified for adults and children, b) The total potential non-carcinogenic health risks for adults and children were determined using the hazard index (HI). The total HI (THI) value was calculated as the sum of individual HIs (HIingestion + HIdermal), c) Carcinogenic health risk (CR) values were calculated for three heavy metals (Cr, Ni and As). According to the findings: a) Ingestion HQ values were found to be higher in adults and children due to As compared to dermal HQ values. According to the HI values, there was a high level of non-carcinogenic health risk in terms of heavy metals in Sukesen, Başpınar, and Gölcük Creeks, varying according to the month and age group. However, for Yavrucak Creek, there has not been appeared to be a non-carcinogenic health risk for adults and children, b) According to the calculated HQdermal and HIdermal values, there was no significant adverse health risk due to dermal exposure for adults and children, c) Children hazard index values were found to be higher than adult hazard index values, highlighting that children were at higher health risk most particularly when it comes to the considered heavy metals, d) The THI values for Sukesen and Başpınar Creeks indicated a significant non-carcinogenic health risk possibility for both adults and children in all sampled months. In Gölcük Creek, a serious non-carcinogenic health risk probability was observed for adults in April and for children during the sampling period, e) The calculated CR values for chromium, nickel, and arsenic indicated that the ingestion pathway poses a higher risk compared to the dermal route, expressing the likelihood of cancer incidence in adults and children. In the context of potential health hazards, to take administrative measures regarding heavy metal contamination, particularly in Başpınar and Sukesen Creeks, is important not only for the protection of public health but also for the sustainability of Mogan Lake.
莫干湖水源中重金属对健康风险的评估,黑龙江
潜在接触重金属所产生的非致癌性和致癌性健康风险对人类健康构成负面威胁。本文对莫干湖流域4条河流(Sukesen Creek、Başpınar Creek、Yavrucak Creek、Gölcük Creek)在人为压力下的水体重金属(Hg、As、Cd、Cr、Pb、Ni、Cu、Zn)进行了分析。在对盆地具有重要娱乐意义的莫干湖也有贡献的小溪的水样中:a)确定了成人和儿童通过摄入和皮肤途径暴露于重金属的非致癌健康风险(HQ); b)使用危害指数(HI)确定了成人和儿童的总潜在非致癌健康风险。总HI (THI)值计算为个体HIs (hiinestion + HIdermal)的总和;c)三种重金属(CR、Ni、as)的致癌健康风险(CR)值计算。根据研究结果:a)与皮肤HQ值相比,成人和儿童由于As摄入的HQ值更高。根据HI值,就Sukesen、Başpınar和Gölcük溪的重金属而言,存在高水平的非致癌健康风险,根据月份和年龄组有所不同。然而,对于Yavrucak Creek,似乎没有对成人和儿童产生非致癌的健康风险,b)根据计算的HQdermal和HIdermal值,成人和儿童没有因皮肤接触而产生重大的不利健康风险,c)发现儿童危害指数值高于成人危害指数值,突出表明儿童面临更高的健康风险,特别是当涉及所考虑的重金属时。d) Sukesen和Başpınar creek的THI值表明,在所有采样月份中,成人和儿童均存在显著的非致癌健康风险可能性。在Gölcük Creek中,4月份观察到成人和儿童在采样期间存在严重的非致癌健康风险概率,e)计算出的铬、镍和砷的CR值表明,摄入途径比皮肤途径具有更高的风险,表达了成人和儿童发生癌症的可能性。在潜在健康危害的背景下,对重金属污染采取行政措施,特别是在Başpınar和Sukesen creek,不仅对保护公众健康,而且对莫干湖的可持续性都很重要。
