Evaluation of microplastic and marine debris on the beaches of Niterói Oceanic Region, Rio De Janeiro, Brazil.

The characterization of microplastics helps to improve sustainable management practices in aquatic ecosystems impacted by plastic litter. Plastic litter and microplastics from four ocean beaches in the Niterói municipality was evaluated in winter and summer. The collection and preparation of microplastic sample procedures followed on the protocol developed by the RLA7025 Project of the International Atomic Energy Agency.

Plastic debris and natural food in two commercially important fish species from the coast of Peru.

The aim of this study was to evaluate the presence of plastic debris in the stomach contents of two commercially important species Ethmidium maculatum and Mugil cephalus from Peru and relate their characteristics to their diet. The contents of 1820 stomachs were analyzed visually to detect the presence of plastics and prey. Of the analyzed samples, 0.

Diversity, ecology, and bioprospecting of culturable fungi in lakes impacted by anthropogenic activities in Maritime Antarctica.

In this study, we accessed culturable fungal assemblages present in the sediments of three lakes potentially impacted anthropogenically in the Fildes Peninsula, King George Island, Antarctica and identified 63 taxa. Cladosporium sp. 2, Pseudeurotium hygrophilum, and Pseudogymnoascus verrucosus were recovered from the sampled sediments of all lakes.

First evidence of microplastic pollution in the El Quetzalito sand beach of the Guatemalan Caribbean.

In Guatemala, assessment of the impacts of microplastic pollution in marine and coastal protected areas has not yet been carried out. Therefore, the main goal of this paper was to evaluate the abundance, composition, physical forms, and the possible sources of plastic debris in the El Quetzalito Beach. The area was intended for biodiversity conservation but has been excessively contaminated by plastic materials from land-based activities.
