Water pollution is a significant problem stemming from several causes, with the contamination of heavy metal(oid)s being primary concern. This especially concerning because poisonous characteristics these and their effects on aquatic ecosystem. research distinguished by its unique methodology for assessing in surface water Bangladeshi rivers over period sixteen years, 2007 to 2022. work seeks elucidate recent results metal(oid) concentrations, levels, multivariate statistical analyses, source identification using positive matrix factorization models, probabilistic health risks. The findings reveal that concentrations chromium, nickel, arsenic, cadmium, lead exceeded acceptable limits drinking established World Health Organization (WHO) factors 4.64, 2.25, 22.51, 45.60, 10.13, respectively. Our meta-analysis, subsequent Principal Component Analysis, indicated increased hazardous metals account 85.47% variation both anthropogenic natural causes. Ecological risk indicators, including metal index (84.06) Nemerow (10.55), contamination. like indicate substantial (PMF) model detected following sources water: industrial (22%), mixed (32%), agricultural activities (27%), (19%). Furthermore, Monte Carlo-simulation-based assessments hazards mean hazard (HI) cancer values adults (301.89 422.76) children (51.56 39.45) significantly recommended limits, suggesting are vulnerable potential non-carcinogenic carcinogenic immediate execution control measures regulations essential avert escalating water, protect ecosystems, mitigate hazards.

BIOREMEDIATION: A SUPERIOR ALTERNATIVE FOR REMEDIATING TANNERY EFFLUENT-CONTAMINATED SOIL

FUDMA Journal of Sciences, Journal Year: 2025, Volume and Issue: 9(2), P. 193 - 208

Tannery effluent poses significant risks to soil health, primarily through contamination with heavy metals like chromium, sulphides, and persistent organic pollutants (POPs). These toxic substances inhibit microbial activity, reducing nutrient cycling matter decomposition essential for fertility. Beneficial microorganisms, including nitrogen-fixing bacteria, are particularly affected, leading altered communities dominated by less advantageous, metal-tolerant species. Accumulation of POPs disrupts enzymatic activities, interferes plant root growth, complicates remediation efforts due pollutant migration groundwater potential entry into the food chain. Prolonged exposure such contaminants diminishes fertility, reduces resilience, ecosystem services, posing threats agricultural productivity environmental health. This review was aimed outline what made bioremediation a superior treatment technology among other methods used in remediating tannery contaminated soil. Efforts mitigate impacts involve combination physical, chemical, biological technologies. Physical washing, flushing, thermal desorption focus on removing or isolating contaminants, while chemical approaches as oxidation, reduction, stabilization transform harmful forms immobilize them. Biological leverages microorganisms plants detoxify sustainably. Bioremediation strategies aid bioaugmentation biostimulation do enhance activity address inorganic effectively more than physical methods. Another excellent called phytoremediation can also effectively, Achieving better technique should be coupled stringent industrial regulations, sustainable tanning methods, stakeholder awareness
