Characterization of Microplastics in Total Atmospheric Deposition Sampling from Areas Surrounding Industrial Complexes in Northwestern Colombia
AI summary Read the abstract
Researchers measured total atmospheric deposition of microplastics near an industrial complex in Cartagena, Colombia, finding that concentrations were highest closest to the industrial zone (9,472 MPs) and decreased with distance, with fiber shapes predominating and weather patterns influencing transport.
In this study, the total atmospheric deposition of microplastics in places near an industrial complex in Cartagena, Colombia is evaluated by taking samples at three points at different distances from the industrial zone. The samples obtained were treated to quantify and identify the type of plastic present, indicating the presence of polystyrene, polypropylene, polyethylene, polyvinyl chloride, and polyethylene terephthalate. The values of microplastics obtained were related to the climatic conditions of the areas (wind and rainfall) to determine these effects on the transport of microplastics. Values of 9472 ± 702 MP were obtained at the point closest to the industrial area and 1455 ± 14 MP at the farthest point, within which a greater proportion were fibers. In this study, it was also possible to determine that the microplastics most affected by the wind were the fragments.

Characterization of Atmospheric Microplastics in a Sub-urban area of northwest of Spain
AI summary Read the abstract
Atmospheric microplastics were characterized in a sub-urban area of northwestern Spain using bulk deposition collectors over an extended period. The study found microplastics in all samples, with fibers being the dominant type and polyester being the most common polymer. The findings contribute to the growing evidence that atmospheric microplastic deposition is widespread and highlight the need for standardized sampling protocols to compare results across studies.
