Impacts of Plastics on Plant Development: Recent Advances and Future Research Directions

Plants, Journal Year: 2023, Volume and Issue: 12(18), P. 3282 - 3282

Published: Sept. 15, 2023

Plastics have inundated the world, with microplastics (MPs) being small particles, less than 5 mm in size, originating from various sources. They pervade ecosystems such as freshwater and marine environments, soils, atmosphere. MPs, due to their size strong adsorption capacity, pose a threat plants by inhibiting seed germination, root elongation, nutrient absorption. The accumulation of MPs induces oxidative stress, cytotoxicity, genotoxicity plants, which also impacts plant development, mineral nutrition, photosynthesis, toxic accumulation, metabolite production tissues. Furthermore, roots can absorb nanoplastics (NPs), are then distributed stems, leaves, fruits. As NPs harm organisms ecosystems, they raise concerns about physical damage effects on animals, potential impact human health via food webs. Understanding environmental fate is essential, along strategies reduce release mitigate consequences. However, full understanding different plastics, whether traditional or biodegradable, development yet be achieved. This review offers an up-to-date overview latest known plastics plants.

Abstract Residual antibiotics in agricultural soils can be of concern due to the development antibiotic resistant microorganisms. Among various antibiotics, oxytetracycline (OTC), streptomycin (ST), and validamycin A (VA) have been used for purposes South Korea; however, studies on biodegradation these soil are limited. Therefore, this study investigated effects pH (5.5, 6.8, 7.4) temperature (1.8, 23.0, 31.2 °C) conditions soil. The tests were carried out field (FS) rice paddy (RS) 30 d with OTC ST 10 VA, residual concentrations monitored over degradation period. Under conditions, rates was lower (11–69%) than that (60–90%) VA (15–96%). half-lives tend decrease increasing value, while half-life increase value. But, effect not statistically significant, except FS RS FS. three greater at higher temperatures (23.0 °C (1.8 °C), decreased temperature. different characteristics explained by (e.g., sorption affinity, chemical forms) organic matter content). results suggest need considered order properly manage

Microplastics and metals: Microplastics generated from biodegradable polylactic acid mulch reduce bioaccumulation of cadmium in earthworms compared to those generated from polyethylene

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 282, P. 116746 - 116746

Published: July 24, 2024

Biodegradable polylactic acid (PLA) mulch has been developed to replace conventional polyethylene (PE) in agriculture as a response growing concerns about recalcitrant plastic pollution and the accumulation of microplastics (MPs) soil.Cadmium is significant soil pollutant China.MPs have shown adsorb metals.In this study earthworm Lumbricus terrestris was exposed either Cd (1.0-100 mg / kg) or MPs (PE PLA, 0.1-3 % w w), combination two, for 28 days.Cd bioavailability significantly decreased presence MPs.In particular, at end experiment, PLA treatments had lower measured concentrations both earthworms (2.127-29.24mg pore water (below detection limits -0.1384 /L) relative PE (2.720-33.77mg kg below -0.2489 L).In our adsorption experiment adsorbed more than with maximum capacities 126.0 23.2 respectively.These results suggest that reduce exposure by removing it from solution reducing its bioavailability.

Effects of polyvinyl chloride and low-density polyethylene microplastics on oxidative stress and mitochondria function of earthworm (Eisenia fetida)

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 283, P. 116847 - 116847

Published: Aug. 10, 2024

Plastics are widely used worldwide due to their convenience. However, microplastics (MPs) accumulation poses a serious threat ecosystem health. Therefore, understanding the effects of MPs on living organisms within native is crucial. Previous studies have primarily focused impacts in aquatic environments, whereas terrestrial ecosystems remained largely understudied. our study assessed soil by characterizing toxic earthworms (Eisenia fetida). Here, we exposed two representative plastics environments: polyvinyl chloride (PVC) and low-density polyethylene (LDPE). Given known link between oxidative stress, next quantified stress markers mitochondrial function assess redox metabolism earthworms. Mitochondria crucial metabolic organelles that generate reactive oxygen species via uncontrolled ATP production. Our findings demonstrated exert different depending type. Neither PVC-exposed groups nor LDPE-exposed exhibited changes as worked action superoxide dismutase (SOD) glutathione (GSH). While treatment types MP did not significantly affect amount species/reactive nitrogen (ROS/RNS) generated, PVC more pronounced effect antioxidant system compared LDPE. was markedly decreased group high LDPE concentrations, suggesting examined concentrations were too low activate compensatory mechanisms. Collectively, exposure only influences defense mechanisms but also alters types.

Ubiquitous microplastics in urban waters have raised substantial public concern due to their high chemical persistence, accumulative effects, and potential adverse effects on human health. Reliable standardized methods are urgently needed for the identification quantification of these emerging environmental pollutants wastewater treatment plants (WWTPs). In this study, we introduce an innovative rapid approach that employs flow imaging microscopy (FlowCam) simultaneously identify quantify by capturing high-resolution digital images. Real-time image acquisition is followed semi-automated classification using customized libraries distinct polyethylene (PE) polystyrene (PS) microplastics. Subsequently, images subjected further analysis extract precise morphological details microplastics, providing insights into behavior during transport retention within WWTPs.
