“…Rao [26] suggested that landfill sites are breeding grounds for many disease-carrying organisms and can impact human health [6]. In addition, studies have indicated that poor waste management can lead to surface and groundwater contamination [27], air pollution [28] soil contamination [29], and health risk [30]. The statistical analysis indicated that households within 250 m-500 m from the landfills faced similar environmental issues such…”

Aim: Urbanization and poor town planning have contributed to large waste generation, poor management, and landfill are sited close to the living environment; hence, high health risk. The study assessed households living near open landfills' health-related exposure and environmental challenges. Methods:The cross-sectional descriptive study was conducted among households living within a radius of 250m (Category A) and 500m (Category) from the landfill based on the World Health Organization (WHO) criteria. The survey identified 122 and 137 households, and one adult was randomly selected to represent each household, resulting in 259 respondents (Category A = 122, Category B = 137). Data was collected through a designed questionnaire and analyzed through descriptive (frequency counts and percentage) and Inferential (Chi-square) statistics. Result:The survey outcome revealed that respondents at both radius have health history of sickness such as malaria (42.6%, 42.3%), skin infection/irritation (13.9%, 24.1%), cholera and diarrhea (21.3%, 13.9%), asthma (12.3%, 5.8%), pneumonia (9.8%, 10.2%), and cancer (-, 3.6%). Individuals within both radii of 250-500m had health symptoms such as skin infection/irritation, nausea, and feverish cold; however, eye irritation, sore throat, diarrhea, and abdominal pain were peculiar symptoms with those within a radius of 250 m (category A). The statistical analysis indicated that households within 250m-500m from the landfills faced similar environmental issues such as littering of the environment, air and water pollution, bad odour, smoke from burning, dust, and infestation of diseasecarrying organisms; however, differences in landfill impact on the environment and noise pollution. Conclusion:Households living nearby landfill areas are at higher risk of health and environmental challenges; however, these risk reduces as households stay farther away (far beyond 500 m) from landfill areas.

“…CF was adopted to ascertain the extent of soil contamination with heavy metals. CF is expressed; of impact on soil [3,4], water [5][6][7], air [8,9], and not excluding human [10,11]. Waste generated in many urban areas of Nigeria comprises several materials and by-products [12,13] capable of releasing toxic agents such as lead, cadmium, mercury, cobalt, arsenic, and other toxic metals into the environment [14].…”

Landfill area is one of developing countries' most common anthropogenically contaminated sites. The pressure of urbanization has led to increased waste generation in major cities, commonly deposited in landfills; hence, heavy metals contaminations are closer to the human environment than ever. The study assessed the environmental risk of Arsenic (As), Cadmium (Cd), Zinc (Zn), Manganese (Mn), Copper (Cu), Colbat (Co), Cranium (Cr), Nickel (Ni), and Lead (Pb) in an abandoned landfill system and health-related risk using United State Environmental Protection Agency model. The Concentration of the elements descended as follows; Mn > Zn > Cr > Pb > Cu > Ni > Co > As > Cd and exceeded the WHO permissible limit. The Enrichment factor (EF) and potential ecological risk (ER) indicated no enrichment and low risk for all the elements except Cd (3.67, 426), with moderate enrichment and very high ecological risk. The hazard index (HI) value of the elements indicated no significant risk of non-carcinogenic effect for both Adults and Children except for Mn in Children with a value of 1.69 × 100; however, the HI value of the elements descended as; Co > Mn > Zn > As > Cd > Cu > Pb > Ni > Cr for adult and Mn > Cd > Co > Cr > As > Zn > Pb > Cu > Ni for children. The total carcinogenic risk (TCR) value of the toxic metals descended as Ni > Cd > Cr > As > Pb for both adults and Children, while the metals showed no carcinogenic to acceptable risk to humans. The PCA indicated that the source and distribution of the elements are lithogenic and anthropogenic influences. Engaging the environment through sustainable practices will ensure efficient waste disposal and management.

“…It is highly recommended to change the disposal of solid waste at high temperatures and anaerobic conditions (Sriram et al 2017;Ryue et al 2020). COD measures the oxygen used to oxidize organic wastes into inorganic constituents (Bhalla et al 2012), quantifying the chemical toxicity and oxidizable toxins (Enitan et al 2018). The measured COD and BOD 5 levels obtained in this study were more than 150 to 500 times higher than the disposal limits of 200 mg/L and 20 mg/L, respectively recommended by (MECA 1993) (Table 5).…”

Characterization and pollution potential of leachate from urban landfills during dry and wet periods in arid regions

Leachate originating from municipal solid waste landfills poses a serious contamination threat to public health. The study performed a bio-physicochemical characterization of leachate from two landfills in Oman, i.e., Multaqa landfill leachate (MLL) and Barka landfill leachate (BLL) before and after rainfall. Samples were characterized for ninety-two (92) parameters. Additionally, the leachate pollution index (LPI) was estimated to assess. The study found a high value of the leachate parameters without any rainfall incidents. Pearson correlations (±ve) have to be seen more than 90% in all cases, which is a strong association (r>0.75) for the measured parameters in both MLL and BLL. Rainfall significantly reduced the concentrations of organic contaminants and solids in leachate due to dilution. The study revealed about 18–29% and 14–28% reductions in the LPI sub-index for organic and inorganic contaminants, respectively, after the rainfall. The overall LPI values were higher compared to similar findings from the literature. Such deviations could be attributed to the unsegregated nature of solid wastes, resulting in the formation of contaminants or from the disposal of a high volume of solid wastes in a smaller area. Therefore, the study recommends efficient management strategies of landfills to reduce potential leachate groundwater contamination.
