ClearPresence and Abundance of Microplastics in Benthic Organisms from Some Niger Delta, Nigeria Coastal Rivers
Researchers investigated the presence and abundance of microplastics in benthic organisms collected from coastal rivers in the Niger Delta region of Nigeria, documenting contamination levels in organisms from these ecologically significant waterways.
Anthropogenic drivers of pollutant presence and composition in first-order streams of the Ona River System, Ibadan, Nigeria
Researchers assessed physicochemical parameters, heavy metals, and microplastic contamination across eight urban rivers in southwestern Nigeria, examining how rapid urbanization drives pollutant loading and shapes contaminant composition in first-order streams of the Ona River system.
Accumulation of cadmium and lead in macroinvertebrates in relation to sediment concentration and the dynamics of environmental parameters in a tropical estuary of the Colombian Pacific
This paper is not relevant to microplastics research — it investigates the accumulation of cadmium and lead heavy metals in macroinvertebrates from a tropical Colombian estuary, focusing on metal pollution rather than microplastic contamination.
Occurrence and Health Implications of Heavy Metals in Microplastics from Otuoke Surface Waters
This study investigated the occurrence of heavy metals associated with microplastics in surface waters in Otuoke, Nigeria, finding that MPs adsorb and concentrate toxic metals and may serve as vectors for metal exposure in local communities consuming fish. (Duplicate record of ID 11006.)
Seasonal variations of water physico-chemistry, heavy metal concentrations and ecological abundance and biodiversity of fish from two Lagoon streams
Researchers monitored water chemistry, heavy metal concentrations, and fish biodiversity across seasons in two Nigerian lagoon streams. Heavy metals often adsorb to microplastics in aquatic environments, and documenting baseline contamination levels is important for understanding cumulative pollution impacts on freshwater fish communities.
Occurrence and Health Implications of Heavy Metals in Microplastics from Otuoke Surface Waters
Microplastics collected from surface waters in Otuoke, Nigeria were analyzed for adsorbed heavy metals, with health risk assessments indicating that consumption of contaminated aquatic organisms could pose risks to local populations from metal-laden plastic particles.
Assessment of Microplastic Pollution in Surface Water and Sediments of Otammiri River, Imo State, Nigeria
Researchers assessed microplastic pollution in the surface water and sediments of Otammiri River, characterizing the abundance, morphology, polymer types, and spatial distribution of microplastics to evaluate contamination levels and ecological risks in this Nigerian freshwater system.
Investigation of microplastics and potentially toxic elements (PTEs) in sediments of two rivers in Southwestern Nigeria
Researchers investigated microplastic and toxic element contamination in sediments of two rivers in southwestern Nigeria. They found microplastic abundances ranging from 67 to 433 particles per kilogram, with polyethylene being the most common polymer type, along with elevated levels of chromium and lead. The study highlights how indiscriminate waste dumping is contaminating Nigerian river ecosystems and calls for stricter enforcement of environmental regulations.
Evaluation of the Effects of Heavy Metals on Water from Illegal Crude Oil Refineries: a Case Study of Three Selected Communities in the Niger Delta Region, Nigeria
This paper is not about microplastics; it measures heavy metal contamination (and associated health risk indices) in surface water near illegal crude oil refineries in three communities of Nigeria's Niger Delta region.
Levels of heavy metals in water and Nile tilapia fish (Oreochromis niloticus) of Eleyele Lake in Ibadan, Nigeria
This is not a microplastics study; it measures heavy metals in water and Nile tilapia from a Nigerian lake, finding that lead concentrations in fish tissue exceeded WHO and FAO limits even though water concentrations appeared acceptable, raising food safety concerns for local consumers.
Geochemical evolution of dissolved trace elements in space and time in the Ramganga River, India
This paper is not about microplastics; it analyzes spatiotemporal variation in dissolved trace element concentrations in the Ramganga River in India across pre-monsoon, monsoon, and post-monsoon seasons.
Heavy Metals and their Effects on Macroinvertebrates Present in the Ojo River, Lagos, Nigeria
Researchers investigated heavy metal concentrations in the tissues of crab, prawn, and crayfish from the Ojo River in Lagos, Nigeria, assessing contamination levels in commercially harvested crustaceans and their implications for human health and aquatic ecosystem integrity.
Characterization of Macro Litter and Microplastics Abundance in the Ogunpa River, Ibadan: Intimation for Solid Waste Management and Environmental Policy
Researchers characterized macro litter and microplastic abundance across five sites on the Ogunpa River in Ibadan, Nigeria during the wet season, finding high plastic contamination driven by inadequate waste management and recommending targeted environmental policy responses.
Assessment of the incidence of microplastics at Ndibe, Cross River, Nigeria
Researchers assessed microplastic occurrence in water and fish samples from Ndibe Beach on the Cross River in Nigeria, documenting widespread contamination at a popular recreational site and highlighting the threat microplastics pose to aquatic ecosystems and local communities in the Niger Delta region.
Presence and Abundance of Microplastics in Benthic Organisms from Some Niger Delta, Nigeria Coastal Rivers
Researchers examined benthic organisms—crabs, oysters, shrimps, lobsters, and others—from seven rivers in Nigeria's Niger Delta, finding 100% microplastic presence across all species and all sampling sites.
Pollution Status of Inland Waterways Serving as Receptacles to Plastic Waste in Rivers State, Nigeria
This study assessed physicochemical water quality, PCB contamination, and PAH contamination in waterways receiving plastic waste in Rivers State, Nigeria. Plastic waste in these waterways contributes to microplastic contamination that compounds the chemical pollution burden on aquatic ecosystems and local communities.
