Human exposure to microplastics (MPs) through drinking water has drawn serious concern recently because of the potential adverse health effects. Although there are reports on occurrence MPs in bottled water, little is known about abundance a whole spectrum with sizes ranging from 1 µm 5 mm due restrictions conventional detection methods. Some studies using micro-Raman spectroscopy can achieve size <10 µm, however, quantitation all was extremely time consuming and only small portion (<10%) would be analyzed. The present study quantified nine brands fluorescence microscopy flow cytometry for ≥50 <50 respectively. average samples found 8–50 particles L−1, while were 1570–17,817 where mineral significantly more than distilled spring samples. modal shape at fragments, Besides, three tap obtained locally analyzed compared samples, less In addition, contamination bottle cap interference by addition salts studied, no significant difference these processes control sample found, suggesting major other manufacturing processes.

Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm length) and possibly even nanoplastics (<1 μm) has recently raised health concerns. In particular, believed be more toxic since their smaller size renders them much amenable, compared microplastics, enter the human body. However, detecting imposes tremendous analytical challenges on both nano-level sensitivity plastic-identifying specificity, leading a knowledge gap this mysterious nanoworld surrounding us. To address these challenges, we developed hyperspectral stimulated Raman scattering (SRS) imaging platform with an automated plastic identification algorithm that allows micro-nano analysis at single-particle level high chemical specificity throughput. We first validated enhancement narrow band SRS enable high-speed single nanoplastic detection below 100 nm. then devised data-driven spectral matching imposed by sensitive narrow-band achieve robust determination common polymers. With established technique, studied plastics from bottled water as model system. successfully detected identified major types. Micro-nano concentrations were estimated about 2.4 ± 1.3 × 10

A steep rise in global plastic production and significant discharge of waste are expected the near future. Plastics pose a threat to ecosystem human health through generation particulate plastics that act as carriers for other emerging contaminants, release toxic chemical additives. Since additives not covalently bound, they can freely leach into environment. Due their occurrence various environmental settings, exert ecotoxicity. However, only 25% have been characterized potential ecological concern. Despite market statistics highlighting substantial burden caused by unrestricted use additives, information on ecotoxicity remains incomplete. By focusing impacts present review aims provide detailed insights following aspects: (i) diversity environment, (ii) leaching from materials, (iii) trophic transfer, (iv) exposure, (v) risks health, (vi) legal guidelines mitigation strategies. These immense value restricting searching eco-friendly alternatives, establishing or revising agencies.

Plastic waste discarded into aquatic environments gradually degrades smaller fragments, known as microplastics (MPs), which range in size from 0.05 to 5 mm. The ubiquity of MPs poses a significant threat ecosystems and, by extension, human health, these particles are ingested various marine organisms including zooplankton, crustaceans, and fish, eventually entering the food chain. This contamination threatens entire ecological balance, encompassing safety health systems. Consequently, developing effective MP removal technologies has emerged critical area research. Here, we summarize mechanisms recently reported strategies for removing ecosystems. Strategies combining physical chemical pretreatments with microbial degradation have shown promise decomposing MPs. Microorganisms such bacteria, fungi, algae, specific enzymes being leveraged remediation efforts. Recent advancements focused on innovative methods membrane bioreactors, synthetic biology, organosilane-based techniques, biofilm-mediated remediation, nanomaterial-enabled strategies, nano-enabled demonstrating substantial potential enhance efficiency. review aims stimulate further innovation methods, promoting environmental social well-being.
