The distribution and abundance of microplastics into the world are so extensive that many scientists use them as key indicators recent contemporary period defining a new historical epoch: Plasticene. However, implications not yet thoroughly understood. There is considerable complexity involved to understand their impact due different physical–chemical properties make multifaceted stressors. If, on one hand, carry toxic chemicals in ecosystems, thus serving vectors transport, they themselves, other cocktail hazardous added voluntarily during production additives increase polymer prolong life. To date, there lack knowledge major concern used plastic industry, fate once dispose environment, consequent effects human health when associated with micro nanoplastics. present study emphasizes most dangerous chemical substances contained all products describe these health, providing detailed overview studies have investigated microplastics.

Plastic Teabags Release Billions of Microparticles and Nanoparticles into Tea

Environmental Science & Technology, Journal Year: 2019, Volume and Issue: 53(21), P. 12300 - 12310

Published: Sept. 25, 2019

The increasing presence of micro- and nano-sized plastics in the environment food chain is growing concern. Although mindful consumers are promoting reduction single-use plastics, some manufacturers creating new plastic packaging to replace traditional paper uses, such as teabags. objective this study was determine whether teabags could release microplastics and/or nanoplastics during a typical steeping process. We show that single teabag at brewing temperature (95 °C) releases approximately 11.6 billion 3.1 into cup beverage. composition released particles matched original (nylon polyethylene terephthalate) using Fourier-transform infrared spectroscopy (FTIR) X-ray photoelectron (XPS). levels nylon terephthalate from several orders magnitude higher than loads previously reported other foods. An initial acute invertebrate toxicity assessment shows exposure only caused dose-dependent behavioral developmental effects.

A Review of Microplastics in Table Salt, Drinking Water, and Air: Direct Human Exposure

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(7), P. 3740 - 3751

Published: March 2, 2020

The ubiquity of microplastics in aquatic and terrestrial environments related ecological impacts have gained global attention. Microplastics been detected table salt, drinking water, air, posing inevitable human exposure risk. However, rigorous analytical methods for detection characterization remain scarce. Knowledge about the potential adverse effects on health via dietary respiratory exposures is also limited. To address these issues, we reviewed 46 publications concerning abundances, sources, air. We summarized probable translocation accumulation pathways within body. Human body burdens through inhalation were estimated to be (0–7.3)×104, (0–4.7)×103, (0–3.0)×107 items per person year, respectively. intake inhalation, especially indoor was much higher than those other routes. Moreover, air impose threats both digestive systems breathing ingestion. Given lifetime microplastics, urgently call a better understanding hazards health.

Microplastics in wild fish from North East Atlantic Ocean and its potential for causing neurotoxic effects, lipid oxidative damage, and human health risks associated with ingestion exposure

The Science of The Total Environment, Journal Year: 2019, Volume and Issue: 717, P. 134625 - 134625

Published: Nov. 14, 2019

Microplastics (MP) pollution has received increased attention over the last few years. However, while number of studies documentating ingestion microplastics by fish increased, fewer have addressed toxicological effects derived from these small items in wild conditions. Here, MP contamination and effect biomarkers were investigated three commercially important species North East Atlantic Ocean. From 150 analysed (50 per species), 49 % had MP. In 3 species, gastrointestinal tract, gills dorsal muscle found. Fish with significantly (p ≤ 0.05) higher lipid peroxidation levels brain, muscle, brain acetylcholinesterase activity than where no These results suggest oxidative damage neurotoxicity through induction relation to and/or MP-associated chemicals exposure. analysed, 32 a total mean (± SD) 0.054 ± 0.099 items/g.
