Heavy metal pollution is a significant environmental concern in Nigeria, posing risks to ecological integrity and public health. This study aims evaluate the existing policies regulations addressing heavy pollution, assess their effectiveness, propose recommendations for improvement. The analysis reveals that while Nigeria has established robust legislative framework, challenges implementation, enforcement, funding persist. impact of reducing influenced by resource constraints, limited capacity, need stronger collaboration between regulatory bodies industries. Community involvement education play crucial role managing emphasizing importance awareness, sustainable practices, local engagement. Remediation strategies, such as bioremediation phytoremediation, offer potential solutions. However, gaps knowledge research exist, calling long-term monitoring, assessments, comprehensive health risk assessments. To enhance effectiveness current policies, periodic reviews, increased funding, community-based monitoring programs are recommended. By these implementing proposed recommendations, can make strides towards mitigating achieving sustainability.

Chromium contamination primarily originates from anthropogenic activities such as industrial discharges, mining operations, and the improper disposal of chromium-containing products, leading to its infiltration into soil groundwater. The persistence chromium in environment poses severe ecological health risks, including bioaccumulation aquatic organisms adverse effects on plant growth microbes. Human exposure through contaminated water or occupational settings is linked respiratory problems, skin disorders, heightened cancer risk. Addressing these challenges necessitates sustainable remediation approaches, highlighting potential biosurfactants eco-friendly alternatives conventional methods. This review was aimed provide an overview different properties application removal, covering key aspects introduction future perspectives. Biosurfactants microbial-derived surface-active agents, exhibit that make them highly effective reducing contamination. Their biodegradability, low toxicity, renewable production ensure minimal environmental impact. Moreover, their amphiphilic nature enhances bioavailability, facilitating microbial uptake reduction. Certain chelate metal ions, preventing migration secondary contamination, while synergistic interactions with microorganisms improve efficiency. By supporting transformation toxic Cr (VI) less harmful (III) promoting precipitation insoluble compounds, offer a versatile solution for mitigating pollution.

Contamination of potentially toxic elements (PTEs) has received widespread attention in urban children’s parks (UCPs) worldwide the past few decades. However, risk assessment PTEs drinking water sources UCPs is still unknown particularly developing countries. Hence, present study investigated spatial distribution, for (Cd, Cr, Pb, Ni, and Cu), health Khyber Pakhtunkhwa, Pakistan. Among PTEs, Cd, Pb had low to high concentrations exceeded safe limits WHO PAK-EPA most UCPs. PCA results showed anthropogenic natural sources, contributing release all Heavy-metal pollution index (PTE-PI) levels UCPs, with highest values 113 116 Sardaryab Park Charsadda (SPC) Zoo Peshawar (ZPP), respectively. evaluation (PTE-EI) also samples (50%) PTE-PI results. To contrary, exhibited PTE-EI The non-carcinogenic HQ HI were below permissible limit (<1) adults children via ingestion dermal contact. CR TCR that (Cr, Ni) carcinogenic (>1.00 × 10−4) both except Cd Ni route, while Cr some route. Consequently, long-term exposure could pose a local population. Thus, suggests government should implement enforcement firm protocols monitoring guidelines environmental regulations mitigate originating from order reduce risks improve public safety areas.

Groundwater quality was investigated in three urban semi-arid multi-industrial metropolitan areas i.e. (Hayatabad Industrial Estate, Peshawar (HIEP), Gadoon Swabi (GIES) and Hattar Haripur (HIEH). The main aim of the study to determine their physicochemical parameters, potentially harmful elements (PHEs) concentration, pollution sources public health risks Khyber Pakhtunkhwa (KPK), Pakistan. parameters (pH, TDS EC), PHEs (Cd, Zn, Pb, Cr Ni) concentrations Mg drinking water were found within permissible limits, except Fe, which exceeded World Health Organization (WHO) acceptable limit. Among PHEs, Zn had highest contribution rates 69.6%, 58.2% 67.64% HIEP, GIES HIEH, respectively, while Cd showed lowest (3.15%, 1.98% 2.06%) for HIEH respectively. Principal component analysis (PCA) significant correlations between with contributions industrial effluents wastewater discharge (46.81%), mixed (34.05%) geo-genic (19.14%) area. carcinogenic risk (CR) Cd, Cr, Ni threshold value 1 × 10 −4 . This suggests that groundwater should also be regularly monitored contamination as over-extraction, industrialization informal E-waste recycling events surges globally, facing related environmental difficulties groundwater.

Excessive heavy metal concentrations in water can pose a threat to human health. The research analyzed 160 groundwater samples used for hygiene and sanitation, of which 62 were consumption, 98 other types drinking analyzed. findings indicate that 6% sanitation 13% (7.8% groundwater, 5.2% refill water) deemed unfit use due elevated certain metals surpassing the maximum limits. As, Cd, Co, Hg, Mn, Pb detected several unsuitable consumption. Several suspected originate from natural sources are Fe, Zn, while Pb, Co have anthropogenic sources. Only arsenic exposure through ingestion pathway posed non-carcinogenic health risk local population. Children found be more susceptible than adult males females. estimated average levels based on > well rainwater spring water. Therefore, it is essential monitor raw at depots study area implement policies related quality sources, technology maintenance processes, processed depots. Additionally, community should educated about household-scale treatment minimize risks consider using untreated

Abstract Dermal contact, ingestion and inhalation of heavy metal poses significant health risk in human subjects. The exposure could be via potable water, soil or air. current experiment design focuses on media exposure. Advanced probabilistic geospatial methods are used this study which evaluates contamination levels risks associated with iron (Fe), arsenic (As), zinc (Zn), copper (Cu), nickel (Ni), chromium (Cr), lead (Pb), cadmium (Cd) samples. samples were collected analysed using ICP-OES after tri-acid digestion, indices such as Geoaccumulation Index (Igeo), Contamination Factor (CF), Pollution Load (PLI), Hazard Quotient (HQ), (HI), Carcinogenic Risk (CR) to assess environmental impacts across the age groups oral ingestion, dermal contact. indicates concentrations follow order Ni > Zn Pb Cu Cr As Cd, more than 60% demonstrating pollution levels. computational method revealed substantial non carcinogenic (HQ 1) (33%) population related Geospatial analysis Monte Carlo simulations helped identifying hotspots tropical coastal area emphasizing need for targeted remediation focusing Pb.

Abstract Urbanization and industrialization's influence on heavy metal contamination in soil surface/groundwater resources warrant ongoing attention to protect public health the environment, especially Nigeria. Soil samples from different depths (0–10 cm, 15–25 25–40 cm) borehole water were studied for physicochemical properties content. The result showed that pH ranged 5.6 6.8, while 5.0 7.5 which is below WHO limits of 6.5–8.5. Other such as organic matter, cationic exchange capacity, metals (zinc (Zn), arsenic (As), lead (Pb) chromium (Cr) assessed fertility pollution indicators. concentrations Zn, Pb Cr within standards, but As Sample C exceeded limits. Heavy concentration order was Zn > Pb. Pearson correlations (r) positive negative relationship between variances ranging − 0.17–0.99 with diverse chemical interactions across all variables analysed. Risk assessment average daily intake dominated through ingestion, low risks dermal contact. Hazard quotient index values one (1), indicating minimal non-carcinogenic adults children via pathways (inhalation, pathways). However, cancer risk slightly USEPA levels, due prolonged exposure. analysis further revealed are more at compared exposure (ingestion dermal) over a long period. study highlights importance continuous monitoring environmental regulations ensure sustainability.
