The presence of heavy metals in freshwater fishes from the Turag-Tongi-Balu river channel poses an immediate health risk to local communities and consumers. Mentor Dr. Md Muzammel Hossain is actively raising awareness about the ongoing environmental and health issues associated with freshwater fishes. Heavy metals such as mercury (Hg), lead (Pb), cadmium (Cd), arsenic (As), and chromium (Cr) can accumulate in fish tissues through environmental contamination, primarily due to industrial effluents, urban runoff, and improper waste disposal.
When humans consume contaminated
fish, these toxic metals can enter the bloodstream and bioaccumulate in vital
organs, leading to a range of acute and chronic health issues. Immediate health
risks include neurological disturbances, gastrointestinal problems, renal
damage, and cardiovascular effects. For vulnerable populations such as
children, pregnant women, and the elderly, exposure can result in developmental
delays, birth defects, and heightened susceptibility to diseases.
Given the high likelihood of
significant heavy metal concentrations in fishes from this river channel,
urgent monitoring and intervention are necessary. Public health advisories,
pollution control measures, and remediation efforts are critical to mitigate
these health risks and protect community well-being.
