Abstract Background While recognition of airborne microplastics is increasing, there are still limited data on the within aerosol size fractions most relevant to human inhalation (PM 10 and PM 2.5 ). Additionally, concerns that many additives used in plastic formulations have endocrine-disrupting properties, which could increase hazards associated with microplastic exposure. Objective To better understand toxicological risks microplastics, more urgently needed mass concentrations both related chemical air we breathe. Inhalation exposure plastic-related species currently uncertain laboratory workplaces. Methods Using a Pyrolysis Gas Chromatography Mass Spectrometry (Pyr-GC/MS) based method, polymeric material small molecule were determined inhalable from two indoor locations. This method represents fast, direct technique can be standardize measurements. Results The seven different polymers determined, average 0.51 μg m −3 for samples 1.14 µg samples. Polycarbonate, polyvinylchloride, polyethylene had highest fraction air. Simultaneously, phthalate-based plasticizers having an concentration 334 ng across all Impact Both their quantified ), using straight forward spectrometry minimal sample preparation. information furthers knowledge exposure, it presents useful methodology quantification pollutants.

Abstract The widespread use of polymers has made our lives increasingly convenient by offering a more and dependable material. However, the challenge efficiently decomposing these materials resulted in surge polymer waste, posing environment health risk. Currently, landfill incineration treatment approaches have notable shortcomings, prompting shift towards eco-friendly sustainable biodegradation approaches. Biodegradation primarily relies on microorganisms, with research focusing both solitary bacterial strain multi-strain communities for biodegradation. Furthermore, directed evolution rational design enzyme significantly contributed to process. previous reviews often undervaluing role communities. In this review, we assess current state three significant fields research, provide practical solutions issues biodegradation, outline potential future directions subject. Ultimately, whether facilitated single bacteria, communities, or engineered enzymes, now represents most effective method managing waste polymers. Graphical

Microplastics (MPs) have been extensively studied in the marine environment recent years, but their occurrence recreational waters, and activities as a source of MPs, less explored. In this study, we investigate temporal variation MPs Salt River, natural surface waterway heavily used for recreation, community swimming pools nearby Tempe, Arizona. Samples were processed using established methodologies MP shapes number concentrations obtained by optical microscopy. The samples water collected during activity ranged from 27,798 to 222,391 MPs/m3, with highest occurring at 16:00 lowest 8:00, consistent activities. Fibers dominant shape (≥ 71%) overall accounting much 96% all peak time (16:00). apartment 59,160 254,574 MPs/m3. terms shape, fibers again (sometimes high 87%) these samples.
