| Abstract | ||||
| Heavy metals are among the most dangerous pollutants in the natural environment due to their persistent toxicity and bioaccumulation problems, and hence they are considered a global problem. Additionally, they are stubborn, and most of them are poisonous to aquatic organisms when they reach a particular concentration. Zooplankton can continue serving as a monitor for the water situation, depending on how highly responsive they are to various contaminants. Zooplankton's ability to accumulate metals was assessed based on the categories of the bioaccumulation factor (BAF). There was no probability since all heavy metal BAFs were less than 1000 (BAF˂ 1000), however iron (Fe) in zooplankton samples from the two drains and aluminum (Al) in drain one sample fell into the 1000< BAF< 5000: bio-accumulative category. The metal pollution index (MPI) was calculated to compare the levels of overall metal pollution in zooplankton. In the studied drains, the values were 16.902 and 17.924. The zooplankton can therefore be widely used in the biological monitoring and assessment of safe environmental levels of heavy metals. | ||||
