Abstract The limited available data on human internal exposure poses a significant challenge in assessing the risks associated with micro and nanoplastics (MNPs) to health. A contributing factor this is scarcity of sensitive analytical methods quantify mass concentration plastic polymers blood. In study we present an improved validated method for quantitatively analysing polyethylene (PE), terephthalate (PET), poly(vinyl chloride) (PVC), poly(methyl methacrylate) (PMMA), polypropylene, polystyrene whole blood samples. We introduce apply stringent quality assurance control procedures, including validation using samples continuous monitoring batch analyses ensure reliability. Expanding upon prior pioneering work by Leslie et al. (2022), optimised pyrolysis-gas chromatography–mass spectrometry (Py-GC-MS) conditions enhance sensitivity selectivity. Recovery experiments demonstrated high level accuracy precision, values ranging from 68 109% Applying ( n = 68), identified 64 samples, PE as predominant polymer, followed PVC, PET, PMMA. 17 polymer concentrations were found exceed limit quantitation, mean 1070 ng/mL summed concentrations, between 170 2490 ng/mL. sum across all 68) was 268 These findings underscore pressing need further research aimed at comprehensive MNP quantification matrices, considering potential health implications.

Macro- and Microplastics in the Antarctic Environment: Ongoing Assessment and Perspectives

Environments, Год журнала: 2022, Номер 9(7), С. 93 - 93

The number of scientists and tourists visiting Antarctica is on the rise and, despite management framework for environmental protection, some coastal areas, particularly in Antarctic Peninsula region, are affected by plastic contamination. few data available occurrence microplastics (<5 mm) difficult to compare, due different methodologies used monitoring studies. However, indications emerging guide future research implement protocols. In surface subsurface waters Southern Ocean, debris >300 µm appears be scarce far less abundant than paint chips released from vessels. Yet, near scientific stations, fragmentation degradation larger items, as well microbeads microfibers into wastewater personal care products laundry, could potentially affect marine organisms. Some studies indicate that, through long-range atmospheric transport, fibers produced other continents can deposited Antarctica.

Microplastic exposure in aquatic invertebrates can cause significant negative effects compared to natural particles - A meta-analysis.

Environmental Pollution, Год журнала: 2022, Номер 315, С. 120434 - 120434

Опубликована: Окт. 20, 2022

Many studies have now reported adverse effects of exposure to microplastics in aquatic organisms. Still, relatively few compared the MPs with those natural particle controls, which makes it difficult separate from chemical effects. In this study, we carry out a meta-analysis 26 compare and particles on animals using three different endpoints - growth, reproduction, mortality. This analysis showed that capacity induce more mortality for some taxonomic groups. However, are not consistent across each endpoint or between We were able clearly discern differing impacts resulting specific polymer types shapes, though negative associated polylactic acid polyethylene, as well fragments opposed beads fibres. Additionally, meta-regression indicated larger MP sizes, higher experimental temperatures, longer periods all generally Future should continue make use controls allow better risk assessment nanoplastics ecosystems.

Microplastic Pollution: Threats and Impacts on Global Marine Ecosystems

Sustainability, Год журнала: 2023, Номер 15(17), С. 13252 - 13252

Опубликована: Сен. 4, 2023

This study investigates the scope of global marine microplastic pollution and its implications on ecosystems human health. We first delve into how plastic enters ocean, with an emphasis accumulation along coastlines, particularly formation impact Great Pacific Garbage Patch (GPGP). Through a concentration map microplastics across five continents, distribution is revealed. Furthermore, effects wildlife are explored, as well their potential entry food chain, posing public health risks. The results our research underscore serious threats to health, emphasizing need for more scientific policy measures address this challenge.

Sources, Degradation, Ingestion and Effects of Microplastics on Humans: A Review

Toxics, Год журнала: 2023, Номер 11(9), С. 747 - 747

Опубликована: Сен. 1, 2023

Celluloid, the predecessor to plastic, was synthesized in 1869, and due technological advancements, plastic products appear be ubiquitous daily life. The massive production, rampant usage, inadequate disposal of have led severe environmental pollution. Consequently, reducing employment has emerged as a pressing concern for governments globally. This review explores microplastics, including their origins, absorption, harmful effects on environment humans. Several methods exist breaking down plastics, thermal, mechanical, light, catalytic, biological processes. Despite these methods, microplastics (MPs, between 1 5 mm size) continue produced during degradation. Acknowledging significant threat that MPs pose human health is imperative. form pollution pervasive air food infiltrates our bodies through ingestion, inhalation, or skin contact. It essential assess potential hazards can introduce. There evidence suggesting may negative impacts different areas health. These include respiratory, gastrointestinal, immune, nervous, reproductive systems, liver organs, skin, even placenta placental barrier. encouraging see most countries taken steps regulate particles. measures aim reduce which today. At same time, this summarizes degradation mechanism impact health, reduction policies worldwide. provides valuable information future research regulatory development.
