Vanadium(V) is a highly toxic multivalent, redox-sensitive element. It widely distributed in the environment and employed various industrial applications. Interactions between V (micro)organisms have recently garnered considerable attention. This Review discusses biogeochemical cycling of its corresponding bioremediation strategies. Anthropogenic activities resulted elevated environmental concentrations compared to natural emissions. The global distributions atmosphere, soils, water bodies, sediments are outlined here, with notable prevalence Europe. Soluble V(V) predominantly exists exhibits high mobility chemical reactivity. transport within media across food chains also discussed. Microbially mediated transformation evaluated shed light on primary mechanisms underlying microbial reduction, namely electron transfer enzymatic catalysis. Additionally, this highlights strategies by exploring their geochemical influences technical implementation methods. identified knowledge gaps include particulate speciation associated behaviors as well processes marine environments. Finally, challenges for future research reported, including screening hyperaccumulators V(V)-reducing microbes field tests approaches.

Nanoplastics induces oxidative stress and triggers lysosome-associated immune-defensive cell death in the earthworm Eisenia fetida

Nanoplastics (NPs) are increasingly perceived as an emerging threat to terrestrial environments, but the adverse impacts of NPs on soil fauna and mechanisms behind these negative outcomes remain elusive. Here, a risk assessment was conducted model organism (earthworm) from tissue cell. Using palladium-doped polystyrene NPs, we quantitatively measured nanoplastic accumulation in earthworm investigated its toxic effects by combining physiological with RNA-Seq transcriptomic analyses. After 42-day exposure, accumulated up 15.9 143.3 mg kg-1 for low (0.3 kg-1) high (3 dose groups, respectively. retention led decrease antioxidant enzyme activity reactive oxygen species (O2- H2O2), which reduced growth rate 21.3 %-50.8 % caused pathological abnormalities. These were enhanced positively charged NPs. Furthermore, observed that irrespective surface charge, after 2 h gradually internalized coelomocytes (∼0.12 μg per cell) mainly amassed at lysosomes. Those agglomerations stimulated lysosomal membranes lose stability even rupture, resulting impeded autophagy process cellular clearance, eventually coelomocyte death. In comparison negatively nanoplastics, exerted 83 higher cytotoxicity. Our findings provide better understanding how posed harmful have important implications evaluating ecological

Heavy metal toxicity in earthworms and its environmental implications: A review

Environmental Advances, Год журнала: 2023, Номер 12, С. 100374 - 100374

Опубликована: Май 1, 2023

Earthworms are important soil organisms, contributing to many beneficial ecological services that can be harmed by heavy metal contamination. Because of their permeable skin and constant contact with through digestive tract, they extremely sensitive Heavy metals get bioaccumulated in bodies cause major health problems. In this review, we describe the findings various studies on toxicity earthworms, mechanisms toxicity, detoxification responses consequences environment. have deleterious impact earthworms at all levels organization, including inhibiting enzyme activities, causing DNA damage, reducing survival, growth cocoon production, altering behavior total earthworm community diversity biomass. These negative effects disproportionate adverse for stability as well serious entire terrestrial ecosystem. So, pollution poses a threat activity posing risk environment human health.

Ecological adaptation of earthworms for coping with plant polyphenols, heavy metals, and microplastics in the soil: A review

Heliyon, Год журнала: 2023, Номер 9(3), С. e14572 - e14572

Опубликована: Март 1, 2023

In recent years, soil pollution by massive accumulation of heavy metals (HMs), microplastics, and refractory hydrocarbon chemicals has become an emerging global concern, drawing worldwide attention. These pollutants influence diversity hindering the reproduction, abundance, thereby affecting aboveground productivity. The scientific community recently emphasized contribution earthworms to metal accumulation, microplastic degradation, decomposition organic matter in soil, which helps maintain structure. This review paper aimed compile facts on how cope with effect HMs, plant polyphenols so that vermiremediation could be widely applied for well-being ecosystem environmentalists. Earthworms have special surface-active metabolites their guts called drilodefensins help them defend themselves against oxidative action polyphenols. They also combat effects toxic other compounds elevating antioxidant activities enzymes converting into harmless or useful nutrients. Moreover, act as biofilters, bioindicators, bioaccumulators, transformers polyphenols, pollutant hydrocarbons. Microorganisms (fungi bacteria) earthworms' gut assist fixation, transformation these toxicants prevent effects. As a potential organism application ecotoxicology, it is recommended propagate agricultural fields; isolate, culture enormously industry, inoculate polluted abate toxicity minimizing health caused well enhance productivity crops.
