OCCURRENCE OF MICROPLASTICS IN THE BURROWING CRABS C. armatum and C. amnicola FROM MANGROVE TIDAL MUDFLATS IN LAGOS, NIGERIA

Microplastics in the surface water, sediments, and mud crabs (Scylla serrata) from Gimaloto Mangrove, Sorsogon City, Philippines

Characterisation of Microplastics in an Isolated Mangrove Island Using Multiple Ecosystem Components Including Brachyuran Crabs

AI summary · Read the abstract

A comprehensive survey of an isolated mangrove island found microplastics in water, sediment, fallen leaves, and the gastrointestinal tracts of three brachyuran crab species, with fiber morphotypes dominant across all compartments, indicating trophic transfer from leaf litter to crabs. Mangroves serve as microplastic sinks and transfer points in coastal food webs, meaning contamination here propagates to higher trophic levels including species consumed by humans.

Protecting mud crabs from pollution by microplastics, per- and polyfluoroalkyl substances, polycyclic aromatic hydrocarbons, pesticides, and heavy metals in mangroves

AI summary · Read the abstract

Researchers reviewed how microplastics, PFAS, pesticides, and heavy metals are threatening mud crab populations in mangrove ecosystems across Southeast Asia, where these crabs are a key food source for millions of people. The study found that biochar application and microbial bioremediation show promise for reducing pollutant levels, but contamination remains a serious threat to food security.

Occurrence and Characteristics of Microplastics in the Surface Water and Sediment of Lagos Lagoon, Nigeria

AI summary · Read the abstract

Researchers characterized the occurrence, abundance, and physical properties of microplastics in the surface water and sediments of Lagos Lagoon, Nigeria, identifying key polymer types and potential local sources. This study fills an important data gap for West African urban water bodies, demonstrating that rapidly developing coastal megacities face acute microplastic contamination threatening both local fisheries and public health.

Presence of Microplastics in Macroinvertebrates of Mangroves in the Colombian Pacific: Are Feeding Behaviors Determinant for its Abundance?

AI summary · Read the abstract

Scientists found tiny plastic particles (microplastics) in every single shellfish and crab sample they tested from mangrove forests in Colombia, with an average of about 25 particles per animal. These particular species, cockles and crabs, are commonly eaten by local communities, meaning the plastic contamination in their environment could be making its way into the human food chain through seafood.
