Plastic Debris in the Marine Environment: History and Future Challenges

Global Challenges, Год журнала: 2020, Номер 4(6)

Опубликована: Апрель 6, 2020

Abstract The success of plastic as a material has shaped the development modern society and challenged older materials in many their established uses. However, is now major component litter extensively reported within marine environment. Impacts from debris have been identified global conservation issue with implications for maritime industries, tourism, life, human health. Although there are benefits plastic, it clear that society's relationship reliance on plastics needs to be addressed. Conversely, alternative replace items, or solutions mitigating release, also need critiqued make sure properties environmental impacts more beneficial. This review examines history impact Current aim mitigate accumulation environment future challenges discussed.

Fourier transform infrared (FTIR) is a spectroscopy technique widely used to identify organic materials. It has recently gained popularity in microplastic (MP) pollution research determine the chemical composition of unknown plastic fragments. However, it could also be evaluate degree ageing MPs collected from environment. In this context, principal aim our been qualitatively natural weathering environmental an Italian freshwater body (the Ofanto River) using ATR-FTIR technology. Furthermore, we compared particles weathered artificial under controlled light and temperature conditions unaltered pristine materials assess results. FTIR spectra were acquired Nicolet Summit (ThermoFisher Scientific) equipped with Everest ATR diamond Crystal plate DTGS KBr detector (wavenumber range 4000-500 cm-1, 32 scans per spectrum, spectral resolution 4 cm-1). The was assessed three different indexes known related changes MPs: Carbonyl Index (CI), Hydroxyl (HI), Carbon-Oxygen (COI). overall results showed that regions reflecting (hydroxyl groups, peaks 3100 3700 alkenes or carbon double bonds, 1600 1680 carbonyl 1690 1810 cm-1) appeared significantly modified calculated for polymers degraded photo thermo displayed general tendency increase time contact irradiation time. Particular enhancements CI PS fragment PE pellet, HI fragments COI observed. Otherwise, following incubation same at constant 45 °C did not further affect particles. Moreover, new unique observed particles, almost all fingerprint region (1500-500 Differences CI, HI, evidenced among morphological MP shapes. On one hand, pellets values ranging 0.05 0.26 mean value 0.17 ± 0.10. Most samples (57%) presented between 0.16 0.30. other slicer modifications lower than (0.05 0.05). This index helps degradation by UV light, increasing enhancing residence Conversely, greater (5.90 2.57) (1.04 0.48) pellets, as well lines, which maximum (11.51). attributed bond vibrations hydroxyl, carboxyl, phenol groups. contrast, frequently C_O bonds found carbohydrates, alkanes, secondary alcohols, ketones. conclusion, characteristics aged ones. interpretation main emphasizes need conduct ecotoxicological experimental studies naturally due unicity their properties, are more helpful understanding effects.

Relationship between the Carbonyl Index (CI) and Fragmentation of Polyolefin Plastics during Aging

Environmental Science & Technology, Год журнала: 2023, Номер 57(21), С. 8130 - 8138

Опубликована: Май 17, 2023

The durability of plastics in the marine environment has emerged as a crucial environmental issue. However, contribution several factors and threshold point after which plastic product generates secondary micro- nanoplastics is still unclear. To investigate interaction parameters with physicochemical properties polyethylene (PE) polypropylene (PP) films environment, polyolefin were subjected to weathering emulated coastal environments for 12 months, focusing on relationship between radiation load, alteration surface, subsequent generation microplastics (MPs). weight average molecular (Mw) was found be strongly correlated generated particles Feret diameter, implying at decreased Mw. A significant strong carbonyl index (CI) diameter PP weathered beach sand identified. This CI-fragmentation involves three sequential stages suggests that spontaneous fragmentation occurs CI values above 0.7.

Plastics and the Environment

Annual Review of Environment and Resources, Год журнала: 2023, Номер 48(1), С. 55 - 79

Опубликована: Ноя. 13, 2023

Plastics are persistent and pervasive throughout the environment have now been reported from deepest parts of ocean to tops highest most remote mountains. There is a body information on sources, degradation, transport plastics as well variety research investigating ecotoxicological wider ecological consequences plastic ingestion accumulation. Such knowledge has obtained with developments in field laboratory methods for identification then well-publicized media public communications. However, although there large focus pollution within past decade, plenty that we do not yet know. Even five years, sources microplastics (1 μm–5 mm) confirmed had previously considered, example, road paints tire wear particles. Initial focused marine environment, but understanding accumulation impacts terrestrial freshwater environments growing. substantial lack basic science efficiency solutions aimed at mitigating pollution. This review highlights some recent (past years) including investigations accumulation, distribution, impacts, provides directions future work.
