The ubiquitous occurrence of microplastics and nanoplastics in aquatic environments is major concern as these priority pollutants are readily ingested by a wide variety organisms. Although quantitative data on the interaction even more so freshwater their with food web still limited, studies have nevertheless demonstrated that micro- or nanosized plastic particles can be various members zooplankton functioning primary consumers. Bacterivorous ciliates crucial microzooplankton. These fascinating microorganisms critical components microbial loops essential links between different trophic levels within web.

Micro/nanoplastics (MPs/NPs) are a growing threat to environmental health as these particles dispersed remote locations. However, the migration process of NPs differs from MPs due their differences in sizes and physicochemical properties, thereby inducing different behaviours fates. While provide surfaces host microorganisms form plastisphere, smaller than microorganisms, which often encapsulated by protein or organic matter unique eco-corona. Both plastisphere eco-corona alter physiochemical property MPs/NPs, changing toxicity. To fully understand toxicity MPs/NPs after forming eco-corona, this review aims evaluate roles toxicities environment. Specifically, discusses formation on NPs, summarizes biochemical mechanisms assesses potential threats humans. Finally, perspectives provided better manage plastic pollution protect environment human health.

Multiple analytical techniques to measure microplastics (MPs) in complex environmental matrices are currently under development, and which is most suited often depends on the aim(s) of research question experimental design. Here, we further broaden suite possible can directly detect MPs suspension while differentiating carbon contained from other natural particles dissolved organic (DOC). Single particle inductively coupled plasma mass spectrometry (sp-ICP-MS) well measuring at trace concentrations, use ICP time-of-flight-MS (ICP-TOFMS) allows one simultaneously monitor entire elemental spectrum assess full composition individual through developing fingerprints. Because not detected a standard operation mode with icp TOF, dedicated optimization was necessary. Subsequently, feasibility monitoring 12C pulses for detection more waters, two proof-of-principle studies were performed waters environmentally relevant DOC backgrounds (≤20 mg/L) presence containing particles, here, algae. Elevated concentrations did impact enumeration suspension, MPs, single algae, aggregates algae clearly distinguished. The simultaneous identification different analytes interest multiplexed sp-ICP-TOFMS experiments utilizing fingerprinting step forward quantifying aqueous samples.

The increasing number of plastic particles in the environment gives rise to a unique ecological niche called plastisphere, which is characterized by dynamic assemblage microorganisms comprising autotrophs, heterotrophs, predators, and pathogens. This paper reviews formation, characteristics, factors influencing terrestrial aquatic plastisphere. plastisphere forms when hitchhiking microorganisms, often bacteria, adhere surfaces alter surface properties for subsequent colonization increasingly tightly clinging microorganisms. not as mobile defined characteristics soil anchoring it. on are dominant surroundings, particularly those phyla Proteobacteria, Actinobacteria, Bacteroidota, Firmicutes, Chloroflexi, Acidobacteria, Cyanobacteria, Ascomycota, Basidiomycota, Chytridiomycota, Ciliophora, Ochrophyta, Chlorophyta. However, compositions microbial species different vary widely they change with time, properties, biotic abiotic environmental factors. Temporal changes due succession.

Abstract Plastic waste comprises polymers of different chemicals that disintegrate into nanoplastic particles (NPLs) 1–100‐nm size, thereby littering the environment and posing a threat to wildlife human health. Research on NPL contamination has up now focused ecotoxicology effects pollution rather than health risks. This review aimed speculate about possible properties carcinogenic neurotoxic as pollutants. Given their low‐dimensional size high surface ratio, NPLs can easily penetrate biological membranes cause functional structural damage in cells. Once inside cell, interrupt autophagy flux cellular debris, alter proteostasis, provoke mitochondrial dysfunctions, induce endoplasmic reticulum stress. Harmful metabolic processes induced by include oxidative stress (OS), ROS generation, pro‐inflammatory reactions. Depending cell cycle status, may direct DNA damage, tumorigenesis, lately carcinogenesis tissues with self‐renewal capabilities like epithelia. In cells able live longest neurons, could trigger neurodegeneration promoting toxic proteinaceous aggregates, OS, chronic inflammation. genotoxicity neurotoxicity are discussed based gathered evidence, when available, within context intracellular uptake these newcomer nanoparticles. summary, this explains how risk evaluation for benefit from accurately monitoring toxicokinetics toxicodynamics at resolution level.
