In this study, Mn, Pb, Ni, Cd, and Cr concentrations in Advanced Biological Wastewater Treatment Plant sludge (ABWWTP) (Turkey) were investigated. The health risks associated with the use of sludge as manure were also calculated. In this context, the metal pollution index (MPI) was determined to assess the pollution degree. According to the obtained data, the highest concentration in ABWWTP sludge was seen in Autumn as 411.33 ± 20.5 mg/kg for manganese and the minimum value was seen in Winter as 0.77 ± 0.04 mg/kg for cadmium. In this study, maximum MPI was calculated as 29.59 in the Summer season, while minimum MPI was calculated as 25.01 in the Spring season. In terms of ingestion and inhalation, we can list the highest HQ_ing and HQ_inh risk of metals in all seasons as male < female < children. The non-carcinogenic risk (HQ) and hazard index (HI) values in terms of ingestion, inhalation, and dermal ways calculated for all heavy metals in all seasons were less than 1. Also, the total HI values were < 1. There were no non-carcinogenic and carcinogenic risks associated with the usage of sludge as manure.

在这项研究中，调查了高级生物废水处理厂污泥（ABWWTP）（土耳其）中的Mn，Pb，Ni，Cd和Cr浓度。还计算了与使用污泥作为肥料有关的健康风险。在这种情况下，确定了金属污染指数（MPI）以评估污染程度。根据获得的数据，秋季发现ABWWTP污泥中的最高浓度为锰，为411.33±20.5 mg / kg，而冬季则为最小值，镉为0.77±0.04 mg / kg。在本研究中，夏季的最大MPI计算为29.59，而春季的最小MPI计算为25.01。在摄取和吸入的方面，我们可以列出最高的HQ _ING和HQ _INH男性<女性<儿童>在所有季节中都有金属风险。在所有季节计算的所有重金属的摄入，吸入和皮肤吸收途径的非致癌风险（HQ）和危害指数（HI）值均小于1。而且，总HI值<1。没有与使用污泥作为肥料相关的非致癌和致癌风险。
