It is important to understand the fragmentation processes and mechanisms of plastic litter predict microplastic production in marine environment. In this study, accelerated weathering experiments were performed laboratory, with ultraviolet (UV) exposure for up 12 months followed by mechanical abrasion (MA) sand 2 months. Fragmentation low-density polyethylene (PE), polypropylene (PP), expanded polystyrene (EPS) was evaluated under conditions that simulated a beach PE PP minimally fragmented MA without photooxidation UV (8.7 ± 2.5 10.7 0.7 particles/pellet, respectively). The rate duration increased more than PE. A 12-month 2-month produced 6084 1061 20 8.3 respectively. EPS pellets susceptible alone (4220 33 particles/pellet), while combination 6 12,152 3276 particles/pellet. number polymer particles decreasing size all types. size-normalized abundance PE, PP, according particle after predictable. Up 76.5% initial volume unaccounted final pellet fragments, indicating large proportion had into undetectable submicron particles.

Emergence of Nanoplastic in the Environment and Possible Impact on Human Health

Environmental Science & Technology, Journal Year: 2019, Volume and Issue: 53(4), P. 1748 - 1765

Published: Jan. 10, 2019

On account of environmental concerns, the fate and adverse effects plastics have attracted considerable interest in past few years. Recent studies indicated potential for fragmentation plastic materials into nanoparticles, i.e., "nanoplastics," their possible accumulation environment. Nanoparticles can show markedly different chemical physical properties than bulk material form. Therefore risks hazards to environment need be considered addressed. However, effect nanoplastics (aquatic) has so far been little explored. In this review, we aim provide an overview literature on emerging topic, with emphasis reported impacts human health, including challenges involved detecting a biological We first discuss sources fates then describe entry routes these particles body, as well uptake mechanisms at cellular level. Since humans not yet extensively studied, focus demonstrating cell responses induced by polystyrene nanoparticles. particular, influence particle size surface chemistry are discussed, order understand recommendations future studies.

Nanoplastic in the North Atlantic Subtropical Gyre

Environmental Science & Technology, Journal Year: 2017, Volume and Issue: 51(23), P. 13689 - 13697

Published: Nov. 21, 2017

Plastics can be found in all ecosystems across the globe. This type of environmental pollution is important, even if its impact not fully understood. The presence small plastic particles at micro- and nanoscales growing concern, but nanoplastic has yet been observed natural samples. In this study, we examined four size fractions (meso-, large micro-, nanoplastics) debris collected North Atlantic subtropical gyre. To obtain portion, isolated colloidal fraction seawater. After ultrafiltration, occurrence nanoscale was demonstrated using dynamic light scattering experiments. chemical fingerprint colloids obtained by pyrolysis coupled with gas chromatography-mass spectrometry. We that signal anthropogenic attributed to a combination plastics. polymer composition varied among classes. At nanoscales, polyvinyl chloride, polyethylene terephthalate, polystyrene were observed. also changes pyrolytic signals decreasing size, which could related structural modification as consequence weathering.
