Preliminary Investigation of Microplastic as a Vector for Heavy Metals in Bye-ma Salt Mine, Wukari, Nigeria
This preliminary study investigated whether microplastics in surface sediments can carry heavy metals, finding that microplastic particles were associated with elevated concentrations of certain metals. This suggests microplastics may act as carriers for toxic heavy metal pollution, compounding the environmental risks they pose.
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.
Occurrence and distribution of micro(meso)plastic-sorbed heavy metals and metalloids in sediments, Gulf of Guinea coast (SE Atlantic)
Researchers analyzed the occurrence and distribution of heavy metals and metalloids associated with micro- and mesoplastics in sediments along the Gulf of Guinea coast in Nigeria. The study found that beach microplastics were dominated by polyethylene, polypropylene, and polystyrene, and carried a range of potentially toxic metals, providing baseline data for ecological risk assessment.
Evaluating the role of microplastics as a vector in metal cycling within the River Thames
Researchers characterized how microplastics in River Thames water adsorb toxic heavy metals, comparing adsorption capacity across different plastic types and water chemistry conditions. Microplastics consistently adsorbed metals including lead, cadmium, and copper, providing the first data on metal-binding capacity for Thames microplastics and supporting their role as carriers of inorganic pollutants in urban rivers.
Microplastics Contamination of Surface Water and Selected Fish Species in Ovia River, Southern Nigeria
Researchers examined microplastic contamination in surface water and two fish species (Notopterus afer and Heterobranchus bidorsalis) from Ovia River in Southern Nigeria, using SEM, FTIR, and EDX to characterize particle size distribution, polymer composition, and elemental contamination. The study provides baseline data on microplastic pollution in a West African river system and documents uptake of plastic particles by commercially important fish species.
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.
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.
A systematic review of microplastics in the environment: Sampling, separation, characterization and coexistence mechanisms with pollutants
Massive microplastic pollution was documented across Africa, Asia, India, South Africa, North America, and Europe, with MPs acting as carriers of heavy metals that enter organisms and cause harm. The adsorption capacity of organic pollutants onto microplastics correlated with hydrophobicity, surface area, and functional group characteristics.
Study on the Adsorption Behavior and Mechanism of Heavy Metals in Aquatic Environment before and after the Aging of Typical Microplastics
Researchers investigated the adsorption behavior and mechanisms of heavy metals by typical microplastics before and after environmental aging, finding that aging significantly alters microplastics' surface properties and capacity to bind metals such as cadmium and lead in aquatic systems.
Micro-nanoplastics and metals : Development of material models and sorption properties in natural environments
This dissertation examines how micro- and nanoplastics interact with heavy metals in natural environments, developing material models to understand their sorption properties. Since plastics can act as carriers for toxic metals — concentrating and transporting them through ecosystems — the research has important implications for understanding combined pollution risks.
Evaluation of microplastic contamination by metals in a controlled environment: A risk to be considered
Researchers found that polyethylene terephthalate microplastics readily adsorb nickel, copper, and zinc metals in aquatic environments, demonstrating that degraded plastics can act as carriers for metal contaminants and pose compounded environmental risks.

This review summarizes quantified levels of heavy metals and hydrophobic organic contaminants sorbed onto microplastics in environmental media, examining adsorption and desorption mechanisms and discussing health implications of ingested microplastics acting as vectors for toxic chemical transport.
The potential of microplastics as carriers of metals
Five types of microplastics were tested for their ability to adsorb heavy metals (Cd, Co, Cr, Cu, Ni, Pb, Zn) in different water matrices, finding significant adsorption of lead, chromium, and zinc—especially on polyethylene and PVC—with surface area and porosity as key drivers. The study identifies microplastics as potential vectors for heavy metal transport and transfer through aquatic food chains.
The Unseen Threat of the Synergistic Effects of Microplastics and Heavy Metals in Aquatic Environments: A Critical Review
This review examines how microplastics and heavy metals interact in water environments, finding that microplastics can attract and concentrate toxic metals on their surfaces through various chemical forces. This combination effect is a concern for human health because contaminated microplastics carrying heavy metals can be consumed through seafood, delivering a double dose of pollutants.
