摘要

The rise of heavy metals (HMs) pollution at a higher level threatens both environmental and public health. The most toxic HMs include Arsenic (As), lead (Pb), Mercury (Hg), Cadmium (Cd), and Chromium (Cr) infiltrate soil and water and enter the food web. It is due to inadequate waste management practices, urbanization, and industrialization. Various traditional HMs decontamination approaches have been employed, but they are inefficient and costly. Therefore, there is need to develop environmentally friendly bioremediation techniques for the removal of HMs from contaminated environmental media. Thus, data on the reported native microorganisms were collected from various toxic metals-contaminated regions of Pakistan to be employed in the future for the remediation of the HMs. The data has shown exceptional HMs detoxification capabilities for Cr (100%), As (99%), Pb (95%), Hg (95%), Cd (98%) by Brevibacterium metallidurans, Micrococcus luteus, Aspergillus flavus, Bacillus thuringiensis, and Aspergillus niger respectively. Moreover, the elimination of Cr has reached to 90% by Pseudomonas aeruginosa, and Aspergillus niger has achieved 81% Ni removal. Further, the World Health Organization (WHO) has reported that HMs threshold levels have exceeded, specifically in Lahore industrial zones and Manchar Lake, displaying the local population's elevated blood metal levels. The microbial remediation mechanisms, including biosorption, bioaccumulation, and biotransformation, can offer eco-friendly, and cost-effective processes. Hence, bioremediation has been proven as an effective alternative for controlling HMs pollution to protect both human health and the environment.
