Plastic pollution in terrestrial ecosystems: Current knowledge on impacts of micro and nano fragments on invertebrates

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 477, P. 135299 - 135299

The increasing accumulation of small plastic particles, in particular microplastics (>1 µm to 5 mm) and nanoplastics (< 1 µm), the environment is a hot topic our rapidly changing world. Recently, studies were initiated better understand behavior micro- (MNP) within complex matrices like soil, as well their characterization, incorporation potential toxicity terrestrial biota. However, there remains significant knowledge gaps understanding wide-extent impacts MNP on invertebrates. We first summarized facts global pollution generation MNP. Then, we focused compiling existing literature examining consequences exposure diversity investigated biological endpoints (from molecular individual levels) compiled get comprehension effects according different factors such shape, polymer type, organism, concentration duration. sublethal are acknowledged literature, yet no general conclusion was drawn highly dependent characteristic experimental design. Finally, synthesis highlighted some research remediation strategies, protocol standardize ecotoxicological studies.

The Development of Yellow Mealworm (Tenebrio molitor) as a Cheap and Simple Model to Evaluate Acute Toxicity, Locomotor Activity Changes, and Metabolite Profile Alterations Induced by Nanoplastics of Different Sizes

Journal of Applied Toxicology, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Due to the wide uses of plastic products, nanoplastics are ubiquitous contaminants in environment. Hence, extensive studies used various models evaluate toxicity nanoplastics. In present study, we developed yellow mealworm ( Tenebrio molitor ) as an alternative model investigate acute Our results showed that microinjection with 500 mg/kg significantly increased death rate mealworms after 24 or 48 h, 100 nm particles being more effective compared 20 ones. Meanwhile, dose‐dependent increase was observed injection 2–200 Exposure 2 but not also led hyperactivity mealworms. Both types altered metabolite profiles, up‐regulated and down‐regulated 9 12 metabolites, whereas 16 25 respectively. Enrichment analysis revealed affected alpha‐linolenic acid metabolism (ko00592) purine (ko00230). For metabolites belonging these pathways, stearidonic guanine. Combined, size‐dependent effects on toxicity, profile changes These indicated potential a cheap simple

Microplastic Passage through the Fish and Crayfish Digestive Tract Alters Particle Surface Properties

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 14, 2025

Most studies on the effects of organisms microplastic characteristics have focused microorganisms, while impact animal feeding behavior, particularly in aquatic species like fish and decapod crustaceans, has been less explored. This study examines how polyethylene spherical microplastics (275 μm diameter) passing through digestive tracts crucian carp (Carassius carassius) Australian crayfish (Cherax quadricarinatus) affect surface properties, particle size, bacterial colonization. The were fed diets with or without microplastics. particles underwent two rounds passage then exposed to known densities. Surface damage, biofilm coverage analyzed using scanning electron microscopy, alterations chemical composition assessed Fourier transform infrared spectroscopy attenuated total reflectance, formation penetration nanoplastics gut tissues glands determined Py-GC/MS. Results show that significantly altered properties reduced affecting nanoplastic into tissues. These changes promoted colonization compared controls. findings suggest activity may play an important role mechanical fragmentation environments, potentially leading their faster degradation.
