Coastal lagoons of West Africa: a scoping study of environmental status and management challenges

This review examines the environmental status of 31 coastal lagoons across West Africa, finding that waste pollution, overuse of resources, and urban expansion are major threats to these ecosystems. Plastic pollution, including microplastics, is among the identified pressures degrading water quality and harming both aquatic life and the human communities that depend on these lagoons. The study highlights significant knowledge gaps about waste management and pollution levels in this region.

Groundwater is a hidden global keystone ecosystem

This study argues that groundwater should be recognized as a "keystone ecosystem" because of its critical role in sustaining surface environments, biodiversity, and human water supplies. Over half of the world's land surface has significant interaction with groundwater, yet it remains overlooked in conservation planning. Protecting groundwater is essential for planetary health, including safeguarding water sources from emerging contaminants like microplastics.

Abundance, morphology and chemical composition of microplastics in sand and sediments from a protected coastal area: The Mar Menor lagoon (SE Spain)

Microplastics were found throughout sand and sediments of the Mar Menor lagoon in southeastern Spain, a protected coastal wetland, with concentrations and polymer types varying by location and depth. The study documents that even legally protected coastal habitats are not shielded from microplastic contamination, raising concerns for the lagoon's fragile ecosystem.

Microplastic levels and sentinel species used to monitor the environmental quality of lagoons: A state of the art in Italy

Researchers reviewed studies on microplastic pollution in Italian lagoon ecosystems and found that only 9 of more than 100 coastal transition environments have been monitored, revealing a major data gap. The review highlights the urgent need for standardized monitoring methods and better-coordinated surveys to understand how microplastics move through these ecologically and economically important habitats.

Microplastic flux through submarine groundwater discharge in a subterranean estuary of Southwest India

Researchers investigated submarine groundwater discharge as a transport pathway for microplastics in a subterranean estuary on the southwest coast of India, finding that this understudied coastal process contributes measurably to marine MP inputs alongside rivers and surface runoff.

Groundwater systems under siege: The silent invasion of microplastics and cock-tails worldwide

This review reveals that groundwater, a critical drinking water source for billions of people, is increasingly contaminated with microplastics from surface pollution seeping downward through soil. Unlike ocean and river pollution, groundwater microplastic contamination has received far less research attention, leaving major gaps in understanding how plastics migrate underground. The findings are alarming because contaminated groundwater directly enters drinking water supplies with little to no treatment in many regions.

Assessment of microplastic pollution: distribution, composition, and sources in the El-Mellah (Algeria) and Bizerte (Tunisia) Mediterranean lagoons

Researchers assessed microplastic pollution in two North African Mediterranean lagoons — El-Mellah (Algeria) and Bizerte (Tunisia) — quantifying abundance, spatial distribution, morphological shapes, and polymer composition to characterize contamination sources and risk to coastal ecosystems.

A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

Scientists reviewed 129 studies and found that tiny pieces of plastic (called microplastics) are contaminating groundwater around the world, which is concerning because groundwater provides drinking water to billions of people. The research shows we don't know enough about this problem, especially in Latin America where only two studies have actually tested groundwater for plastic contamination. This matters because we need better monitoring and policies to protect our underground water sources from plastic pollution that could affect human health.

Subterranean estuaries: An overlooked pathway for microplastic transport to our oceans

Researchers quantified microplastic concentrations in the subterranean estuary of Malpe, India, and calculated the flux entering the Arabian Sea through submarine groundwater discharge, finding a mean concentration of 7.56 MPs/L and demonstrating that subterranean estuaries represent a significant but overlooked microplastic transport pathway.

Microplastics in sediments of artificially recharged lagoons: Case study in a Biosphere Reserve

Microplastics were found in sediments of shallow wetland lagoons in Spain, with wastewater-receiving lagoons having higher concentrations and more fibers and fragments. The study suggests that even protected wetlands declared UNESCO Biosphere Reserves are accumulating microplastic pollution from agricultural and urban water sources.

First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico

This is the first study to investigate microplastic contamination in groundwater in Latin America, examining a coastal aquifer in Northwest Mexico. Researchers found microplastics at all six sampled locations and at multiple depths, confirming that groundwater is not immune to this type of pollution. Since millions of people depend on groundwater for drinking water, these findings raise important questions about microplastic exposure through water supplies.

A review on microplastics pollution in coastal wetlands

Researchers reviewed existing studies on microplastic pollution in coastal wetlands — ecosystems like mangroves, salt marshes, and tidal flats — summarizing where microplastics accumulate, how they get there, and how they affect wildlife and ecosystem function. These habitats are especially vulnerable because they sit at the boundary between land and sea, trapping plastics carried by both rivers and ocean tides.
