Microplastic particles in river sediments and water of southwestern Nigeria: insights on the occurrence, seasonal distribution, composition, and source apportionment
Researchers surveyed microplastic contamination in river water and sediments across southwestern Nigeria, providing some of the first baseline data for the region. They found microplastics at every sampling site, with fibers and fragments being the most common forms, and concentrations varying by season and location. The study points to urban runoff, agricultural activities, and inadequate waste management as the primary sources of this pollution.
Contamination, morphological and chemical characterization, and hazard risk analyses of microplastics in drinking water sourced from groundwater in a developing nation
Researchers analyzed groundwater from six coastal districts in a developing nation and found widespread microplastic contamination, with fibers and fragments of polyethylene and polypropylene being the most common types. Since groundwater is the primary drinking water source in many developing countries, this contamination represents a direct pathway for microplastic ingestion by millions of people.
Occurrence and Assessment of Human Exposure to Microplastic Particles in Bottled Water From Southwest, Nigeria
Researchers tested eight brands of bottled water from southwest Nigeria and found microplastics in all of them, averaging about 15 particles per liter, mostly in the form of fibers. Children were estimated to consume three to four times more microplastics per kilogram of body weight than adults from bottled water. The study adds to growing evidence that bottled water is a significant source of human microplastic exposure, especially for children.
From source to distribution channel: A baseline study of microplastic occurrence in drinking water in Ogun State, Nigeria
Researchers measured microplastics in the drinking water system of Ogun State, Nigeria, from raw water through treatment to tap water, finding 10-16 particles per liter at every stage. Treatment plants removed about 40% of microplastics, but levels actually increased again in tap water, likely from contamination in the distribution pipes. Children were estimated to consume more microplastics per body weight than adults, highlighting the need for better water treatment in developing countries.
Environmental and Toxicological Perspectives of Soil Microplastics in Northern Nigeria
This study examined microplastic occurrence and toxicological implications in soils of Northern Nigeria, identifying agricultural plastics, industrial waste, and urban runoff as key sources. The research addressed a gap in African soil MP research and highlighted ecosystem and food safety risks in the region.
Groundwater quality and associated health risks in the Eastern Region of Ghana
Researchers assessed groundwater quality across 136 boreholes in eastern Ghana and found that about 32% had poor to unsafe water quality, with contamination from iron, manganese, fluoride, and nitrates. While not focused on microplastics specifically, the study reveals that groundwater relied on by millions of people in developing regions faces multiple contamination threats. These findings connect to microplastics research because plastic particles in soil can also leach into groundwater supplies.
Abundance and Distribution of Microplastics as Emerging Contaminants in Public Water Supply Dams of Jos-Bukuru Metropolis, Plateau State
Researchers measured microplastic concentrations in raw water from public water supply dams in the Jos-Bukuru metropolitan area of Nigeria using oil extraction methods. Microplastics were detected across all sampled facilities, with concentrations varying alongside physicochemical water parameters, pointing to infrastructure and catchment management as key risk factors.
First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
Researchers conducted the first investigation of microplastic pollution in groundwater in Latin America, analyzing six capped boreholes in a coastal aquifer in northwest Mexico for microplastic abundance, concentration, and characteristics. The study detected microplastics in groundwater samples, establishing baseline contamination data for this understudied environmental compartment and raising concerns about drinking water quality in the region.
First evidence of microplastics and their characterization in bottled drinking water from a developing country
Scientists in a developing country analyzed 10 brands of bottled drinking water and found microplastics in all samples, with concentrations varying by brand. The most common particles were polyethylene and polypropylene fragments and fibers, likely originating from the plastic bottle caps and packaging. This study adds to evidence that bottled water is a significant source of daily microplastic intake for people worldwide.
Distribution and transport of microplastics in groundwater (Shiraz aquifer, southwest Iran)
Researchers investigated microplastic contamination in groundwater from an alluvial aquifer in a semi-arid region of Iran. They identified microplastics in all sampled wells, with fibers and fragments being the most common shapes and polyethylene the dominant polymer type. The study demonstrates that groundwater, an important source of drinking water, is not immune to microplastic contamination and calls for more research on transport mechanisms in subsurface environments.
Microplastic Presence in Sediment and Water of a Lagoon Bordering the Urban Agglomeration of Lagos, Southwest Nigeria
