ClearRecent status of water quality in Bangladesh: A systematic review, meta-analysis and health risk assessment
Researchers conducted a comprehensive review of water quality in Bangladesh, finding that heavy metals, pesticides, fecal bacteria, and emerging contaminants — including microplastics and antibiotic residues — are widespread in water bodies, posing serious health risks to a large portion of the population. The study highlights an urgent need for stricter water quality laws and enforcement in the country.
Heavy Metal Contamination in Surface Water of Harike Wetland, India: Source and Health Risk Assessment
Researchers measured levels of arsenic, cadmium, chromium, lead, and zinc in the surface water of Harike Wetland in India across different seasons. They found that cadmium and lead exceeded safe drinking water standards, particularly during winter months, with industrial discharge and agricultural runoff identified as primary sources. The health risk assessment indicated that these contaminated waters pose potential non-cancer health risks, especially for children.
Assessment of seasonal variation of heavy metal pollution and health risk in surface sediments at the Karnaphuli River confluences of Chattogram, Bangladesh
This paper is not directly about microplastics; it assesses seasonal heavy metal pollution in river sediments at Chattogram, Bangladesh, focusing on contamination indices and health risks from dermal exposure to metals like cadmium, lead, and arsenic.
Assessment of potentially toxic elements in groundwater through interpolation, pollution indices, and chemometric techniques in Dehradun in Uttarakhand State
Researchers assessed potentially toxic heavy metals (including iron, cadmium, lead, and chromium) in groundwater across an industrial region of northern India, finding contamination levels linked to agricultural runoff, industrial discharge, and land use patterns that pose ongoing health risks to local communities.
Many oil wells, one evil: comprehensive assessment of toxic metals concentration, seasonal variation and human health risk in drinking water quality in areas surrounding crude oil exploration facilities in rivers state, Nigeria
Researchers assessed toxic metal concentrations in drinking water near crude oil exploration facilities in Nigeria, finding seasonal variations and levels exceeding safety thresholds that pose serious health risks to surrounding communities.
Spatio-temporal evaluation of trace element contamination using multivariate statistical techniques and health risk assessment in groundwater, Khulais, Saudi Arabia
Researchers assessed trace element contamination in groundwater across 19 sites in the Khulais region of Saudi Arabia over two seasons. Using statistical analysis, they identified both agricultural runoff and natural geological sources as contributors to elevated levels of toxic metals in the water. The health risk assessment found potential non-carcinogenic and carcinogenic risks for local populations who rely on this groundwater for drinking and agriculture.
Assessment of Heavy Metal Contamination in Beach Sediments of Eastern St. Martin’s Island, Bangladesh: Implications for Environmental and Human Health Risks
Researchers measured heavy metal levels in beach sediments on St. Martin's Island, Bangladesh, and assessed the ecological and human health risks. While most metals were within acceptable ranges, some locations showed elevated levels of manganese and iron linked to human activities like tourism and fishing. Though focused on heavy metals, the study's methods for assessing coastal contamination are applicable to microplastic pollution monitoring in similar beach environments.
Distribution, Sources, and Heavy Metal Interactions of Microplastics in Groundwater and Sediment of Semi‐Arid Regions of Northwest India
Researchers found microplastics at every sampling location in groundwater and sediment in a semi-arid region of northwest India, with concentrations reaching up to 122 particles per liter in well water. The groundwater also contained dangerously high levels of arsenic and manganese, and while a direct link between microplastics and heavy metals was not confirmed in water samples, electron microscopy showed heavy metal particles attached to microplastic surfaces in sediment.
Many Oil Wells, One Evil: Potentially toxic metals concentration, seasonal variation and Human Health Risk Assessment in Drinking Water Quality in Ebocha-Obrikom Oil and Gas Area of Rivers State, Nigeria
Researchers assessed heavy metal concentrations and seasonal variation in drinking water from an oil and gas extraction area in Nigeria, finding contamination levels that pose significant human health risks including potential neurological and carcinogenic effects.
The seasonal assessment of heavy metals pollution in the waters of the Mediterranean and Atlantic seas of Morocco
This study measured heavy metal concentrations (Cd, Pb, Zn, Fe, Cu, Cr, Ni) in water samples from both the Mediterranean and Atlantic coasts of Morocco, evaluating seasonal variation in metallic pollution and associated health risks from seafood consumption.
Carcinogenic and non-carcinogenic health risk assessment of river Ganges in different climatic conditions and regions of Uttarakhand, India
Researchers assessed health risks from heavy metals in the Ganges River, finding elevated arsenic at some sites and correlations between physicochemical parameters and metal concentrations.
Negative Effects of the Urban River Pollution on the Environment and Human Health in Bangladesh
This study examines the severe pollution affecting Bangladesh's urban rivers, including the Buriganga and Karnaphuli, over the past 40 years. Researchers found that contaminants from industrial discharge, urbanization, and waste disposal have led to high metal concentrations, particularly during the dry season, posing threats to downstream ecosystems and public health.
Total Suspended Solids (TSS) Spatial Distribution of Manganese in Resident Well Impacted by Residential Activity: A Case Study of Medokan Ayu District-Surabaya
Researchers tested water quality in residential wells in Surabaya, Indonesia, finding that manganese levels exceeded safety standards in several wells, alongside high suspended solids concentrations. The results highlight how residential activities can contaminate local groundwater, raising public health concerns for communities relying on these wells.
A study on various pollutants in water and their effect on blood of the consumers
Researchers tested drinking water supplied to students in Sahiwal, Pakistan and found contamination with toxic metals, pesticides, and arsenic at levels exceeding WHO safety limits, and linked these pollutants to measurable effects in the blood of water consumers. The study illustrates how inadequate water infrastructure and industrial waste disposal create serious public health risks.
Minerals and Heavy Metal Composition in Seaweeds of the Eastern Coast, Northern Bay of Bengal, Bangladesh
Researchers analyzed mineral and heavy metal content across nine seaweed species collected from the Bangladesh coast, finding species- and phyla-specific variation in Ca, Mg, Fe, Zn, Mn, Cu, Pb, and Cd concentrations linked to environmental parameters and metabolic factors.

An overview of the occurrence and distribution of microplastics in multi-environmental components of Bangladesh
Researchers compiled and analyzed studies on microplastic pollution across multiple environments in Bangladesh, including water, soil, air, and food. They found that microplastic contamination is widespread throughout the country but that significant knowledge gaps remain, particularly regarding long-term health and environmental impacts. The study calls for standardized monitoring methods and stronger policies to address plastic pollution in one of the world's most densely populated nations.
