Macroplastic and Microplastic Abundance at the Greenfield Mangrove Site in Guyana
AI summary Read the abstract
Researchers surveyed a mangrove site in Guyana and found both macroplastics and microplastics present across sampling locations. Plastic items including bags, bottles, and fragments were the most common forms of pollution found. The study documents plastic contamination in a coastal mangrove ecosystem that had not previously been assessed.
In the past decades, the use of plastic, particularly single-use plastics, has greatly increased. Guyana is among the developing countries struggling to deal with this new wave of plastic consumption, resulting in indiscriminate dumping and extensive pollution of the environment. This study was designed to determine the abundance and distribution of microplastics and macroplastics at the Greenfield mangrove site, East Coast Demerara, Guyana.

Scientists found microplastics, tiny plastic particles, mostly fibers, in every sediment sample they tested from Guyana's coastal mangrove forests, which protect shorelines and support local fisheries. This matters because these mangroves are a key part of the seafood supply chain, meaning the plastic contamination found there could work its way into the fish and shellfish people eat, and ultimately into our own bodies. The findings highlight the need for better plastic waste management to protect both these critical ecosystems and the food they help produce.

AI summary Read the abstract
Researchers assessed microplastic contamination levels in mangrove wetlands in Ghana, examining how mangrove tree morphology facilitates plastic accumulation and what concentrations and polymer types are present in these coastal ecosystems. The study addressed threats to mangrove ecological services including water quality improvement, carbon sequestration, and coastline protection posed by plastic pollution.
Microplastic in mangroves: A worldwide review of contamination in biotic and abiotic matrices
AI summary Read the abstract
This worldwide review analyzed 53 studies on microplastic contamination in mangrove sediments, water, and organisms across Asia, America, and Africa, finding that research is geographically limited and lacks wide-scale coverage of mangrove coastlines. Most studies characterized microplastic type, size, color, and morphology but did not assess ecological risks.
