Metal Pollution Is a Foregone Conclusion of Haphazard Industrialization that Accelerate Human Health Problems

Concentrations of various heavy metals exceeded the permissible limits in some commercially important fishes at Meghna River adjacent to Narsingdi district most probably poses serious human health risks.

In the latest research, alarming level of heavy metals (Pb & Zn) concentrations was recorded in some fishes namely Amblypharyngnodon mola, Colisa lalia, Tetraodon cutcutia, Barbodes sarana, Labeo calbasu, Puntius sarena, Ompok pabda, Aila coila, Mastacembelus armatus, Glossogobius giuris, Nandus nandu, Tenualosa ilisha, Lepidocephalichthys guntea, Xenentodon cancila and Stinging catfish by Md. Simul Bhuyan, Muhammad Abu Bakar, Aysha Akhtar and Md. Shafiqul Islam. Gradual increase of metals in human body via fish consumption triggering some chronic diseases (irritability, muscular stiffness and pain, loss of appetite, nausea, kidney dysfunction, skeletal damage and reproductive deficiencies etc).

“In-situ detection of these metals can be great concern to general people but indispensable resources for the local and government authority for the meaningful as well as marginalized management of the river Meghna”, Bhuyan said.

In the paper, Bhuyan reported the values of heavy metals in 32 commercially important fish species for three consecutive seasons (Rainy, Winter and Pre-monsoon). Among the reported values, some values in 15 fish species surpassed the allowable limit set by FAO, WHO, EU, United States Food and Drug Administration (USFDA), US Environment Protection Agency (US/EPA) and England guidelines. Subsequent increase of heavy metals concentrations can be devastating factor for aquatic organisms and human being.

Bhuyan suggested that “Quantification of heavy metals concentrations in fishes of the Meghna River can be essential element for the ecological and biological ecosystem guard. Hopefully, this data resources would be helpful for the scientist community and policy makers of the country. Furthermore, it could bring revolution in the management of river water as the pollution is at shocking rate.”

In rapid developing world, industrialization is inevitable for the economic growth of the country. But economic development would be more sustainable if the industrialization is established in an eco-friendly way. Today’s world give less preference on the environment and that’s why environment considered us as prime opponent taking revenge. As many scientist noted that, heavy metal pollution is great problem for river water and its adjacent dwelling people. Heavy metals are long persistent non-biodegradable elements that enter into our daily meal through biological food chain. Ultimately, it not only harms the river ecosystem but also the health of human posing some long-lasting diseases. For improvement from this odd situations it must be encourage to establish eco-friendly development. Recent paper by Bhuyan emphasize on the human health risks related to heavy metals and ways for coping with the adverse condition.
