Santas Basin is suffering from microplastic pollution, impact on the economy and biodiversity

The waters of Santas BasinBrazil’s southeastern coast, contaminated Micholsticks, Less than 5 millimeters of cells, with fatal effects Biodiversity Navy And the possible risks for human health.

This is a study from the State University of Rio de Janeiro (URJ) published in Ocean and Coastal Research. This research reveals the presence, shape, color and size of waste in one of the most strategic areas for production Oil and gas There is no country.

In an area of ​​about 350,000 square kilometers, the Santas Basin covers the coast of Rio de Janiro, Sao Paulo, Parana and Santa Caterina. Unlike a crucial item The oil industryThis area is a High sea biodiversityThis can cause more harm to pollution.

The federal government controls the import of solid waste to increase the circular economy

The study analyzed 30 water samples collected at seven points in 2020 and 2021 winter and all displayed somewhat somewhat Pollution By microplastics. In total, 1,006 cells were identified, most of which were strict fragments (51.8%), followed by movies (24%) and fiber (16.4%).

The waste found in the main Plastic packagingHow Bags, bottles and daily use containersIn addition to cosmetic residues.

Pollution by microplastics

The study shows that microplastics levels in the Santas Basin are comparable to other areas The Atlantic OceanWere, and,, and,, and,, and,.. Including areas with no exploration of oilCreams from Brazilian coast, Portugal and China.

Despite the proximity to fixed platforms and severe sea traffic, the statistical difference between the analyzed points is not found. This indicates that sea scientific factors such as winds, chains, waves and rain in disperse of these cells than industrial activities – indicates that these cells play a very important role.

Gisel Labo-Hazdu, one of the researchers, warns of the effects of pollution, which has crossed Sea atmosphere. “Microplastic fragments high incidence affecting local fishing, contamination Sea fruits And fish, what Can cause financial risks and losses to public health“He said.

Fish in space? The project wants to bring food to astronauts on the moon and create less garbage

It also highlights the possible impact on tourism Sea dwelling declineLike coral and mangroves, in the long run, environmental elasticity may lose.

Authors suggest that the study can support the results, based on the results Public policies To control sea pollution, strengthen the environmental protection areas and promote awareness campaigns Inappropriate disposal The remains.

Research also reinforces the need for continuous monitoring of the region and the most strict control of industrial activities in environmental sensitive areas.
