Abstract

Heavy Metals (HMs) concentrations in a sediment sample from Habbaniyah Lake (HL), Iraq (Cr, Cd, Ni, Fe, Co, Zn, Pb, and Cu). 33 locations have been selected in the field of study from October 2020 to April 2021 to evaluate the contamination of HMs in sediments by using pollution load index (PLI), contamination factor (CF), Contamination degree (CD), and geo-accumulation index (I-geo). Atomic Absorption Spectrometer AAS was used to determine heavy metal concentrations (USA Phoenix-986). The following are the average concentrations: 2152.97 mg/kg for Fe, 47.35 mg/kg for Pb, 25.18 mg/kg for Cr, 18.00 mg/kg for Ni, 10.60 mg/kg for Co, 9.57 mg/kg for Zn, 4.53 mg/kg for Cu and 3.53 mg/kg for Cd during the research time. The average concentration of Pb, Ni, Fe, and Cd surpassed the USEPA recommendation. Cd is responsible for extremely high contamination; Pb is responsible for moderate pollution and severe contamination at some places based on the contamination factor (CF). According to contamination degree (CD), The Lake is classified as significant pollution degree and very pollution degree in some sites. Results indicated that HL is not contaminated with HMs according to geo-accumulation index and PLI for all sample locations during the study period. The lake is unpolluted by Fe, Cr, Co, Ni, Zn, and Cu according to contamination factor (CF), geo-accumulation index (I-geo), pollution load index (PLI), and Contamination degree (CD).

伊拉克Habbaniyah湖沉积物中重金属的评价

伊拉克Habbaniyah湖（HL）沉积物样品中的重金属（HM）浓度（Cr、Cd、Ni、Fe、Co、Zn、Pb和Cu）。从2020年10月到2021年4月，在研究领域选择了33个地点，通过使用污染负荷指数（PLI）、污染因子（CF）、污染程度（CD）和地质累积指数（I-geo）来评估沉积物中HMs的污染。原子吸收光谱仪AAS用于测定重金属浓度（美国Phoenix-986）。以下是研究期间的平均浓度：Fe 2152.97 mg/kg，Pb 47.35 mg/kg，Cr 25.18 mg/kg，Ni 18.00 mg/kg，Co 10.60 mg/kg，Zn 9.57 mg/kg，Cu 4.53 mg/kg，Cd 3.53 mg/kg。铅、镍、铁和镉的平均浓度超过了美国环保局的建议。镉是造成极高污染的原因；根据污染因子（CF），Pb在一些地方造成中度污染和严重污染。根据污染程度（CD），该湖在一些地点被划分为显著污染程度和非常污染程度。结果表明，根据地质累积指数和研究期间所有样本位置的PLI，HL未被HMs污染。根据污染因子（CF）、地质累积指数（I-geo）、污染负荷指数（PLI）和污染程度（CD），该湖未受到Fe、Cr、Co、Ni、Zn和Cu的污染。
