Abstract
This study aimed to determine the amount of heavy metal pollution in the Al Garraf River sediment in Wasit, Iraq. Seven samples were gathered from the Al-Gharraf River in July 2021. GPS was used to determine the geographic location of these samples. The pollution level in the Al Gharraf River sediments caused by manganese, chromium, cadmium, cobalt, zinc, nickel, copper, and lead pollution indices such as enrichment factor, geo-accumulation, contamination factor, and pollution load were used to analyze the situation. Although geo-accumulation has mostly been used to evaluate contamination in freshwater sediment, one of the most frequently utilized factors is an enrichment to quantify to determine degrees of anthropogenic contamination and ratios of enrichment. On the other hand, the pollution load index is calculated as the number of times the concentration of heavy metals in sediments exceeds the concentration and level and is used for estimating the total amount of toxicity of heavy metals in samples. At the same time, our study discovered that cadmium is heavily polluted (contamination value is 5.70) in Al Gharraf River sediments, while nickel (1.51) and lead (1.75) are moderately polluted, but that the metals manganese, cobalt, chromium, zinc, and copper are not.
