Quantification and characterization of atmospheric microplastics in a coastal urban area of the city of Lima, Peru
AI summary Read the abstract
This study quantified and characterized atmospheric microplastic deposition in a coastal urban area of Lima, Peru, finding that microplastics in the air are an emerging but understudied pollution problem in the region. The research addressed a gap in South American data on airborne microplastic behavior and distribution.
Microplastics are currently considered an emerging problem. That are mainly associated with the excessive use and poor disposal of plastic waste, a problem that has worsened worldwide in recent decades. Studies on the presence of microplastics are limited due to the lack of knowledge on their behaviour and incidence in ecosystems, especially in the atmosphere, and on their consequences on human health. We were conducted a study in a coastal urban area of the city of Lima-Peru, with the main of quantifying the presence of atmospheric microplastics and identifying their morphological characteristics such as shape, size and colour. The result obtained was in the presence of 1598 microplastic particles (in 30 days of monitoring), 68% were fragment type, 22% fiber type and 10% sphere type. The predominant colours were blue and green, and the average size found ranged from 2.495-216 μm. Meteorological conditions were also considered in relation to contaminant deposition. The study is one of the first carried out in Peru, so it is expected that the information generated will be useful to obtain more knowledge about this new pollutant.

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.
