Microplastic (MP) pollution is becoming a global problem due to the resilience, long-term persistence, and robustness of MPs in different ecosystems. In terrestrial ecosystems, plants are exposed MP stress, thereby affecting overall plant growth development. This review article has critically analyzed effects stress plants. We found that stress-induced reduction physical accompanied by two complementary effects: (i) blockage pores seed coat or roots alter water nutrient uptake, (ii) induction drought increased soil cracking MPs. Nonetheless, physiological under four excessive production ROS, alteration leaf root ionome, (iii) impaired hormonal regulation, (iv) decline chlorophyll photosynthesis. Considering that, we suggested targeting redox regulatory mechanisms could be beneficial improving tolerance plants; however, antioxidant activities highly dependent on species, tissue, type, dose. also indirectly reduces altering productivity. However, MP-induced negative vary presence surface functional groups particle sizes. end, utilization agronomic approaches, including application regulators, biochar, replacing plastic mulch with crop residues, diversification, biological degradation, ameliorate The efficiency these methods MP-type-specific dose-dependent.

The harmful effects of microplastics (MPs) pollution in the soil ecosystem have drawn global attention recent years. This paper critically reviews MPs on microbial diversity and functions relation to nutrients carbon cycling. Reports suggested that both plastisphere (MP-microbe consortium) MP-contaminated soils had distinct lower than non-contaminated soils. Alteration physicochemical properties interactions within facilitated enrichment plastic-degrading microorganisms, including those involved (C) nutrient conferred a significant increase relative abundance nitrogen (N)-fixing phosphorus (P)-solubilizing bacteria, while decreased nitrifiers ammonia oxidisers. Depending types, increased bioavailable N P contents nitrous oxide emission some instances. Furthermore, regulated functional activities owing combined toxicity organic inorganic contaminants derived from frequently encountered environment. However, thorough understanding among other still needs develop. Since currently available reports are mostly based short-term laboratory experiments, field investigations needed assess long-term impact (at environmentally relevant concentration) microorganisms their under different types agro-climatic conditions.

Polyethylene microplastics have been detected in farmland soil, irrigation water, and soil organisms agroecosystems, while plastic mulching is suggested as a crucial source of microplastic pollution the agroecosystem. Plastic mulch can be broken down from debris to through environmental aging degradation process farmlands, colonization polyethylene-degrading microorganisms on polyethylene eventually enzymatically depolymerize molecular chains with CO2 release tricarboxylic acid cycle. The selective by cause changes microbial community composition, it consequently elicit enzyme activities nutrient element content soil. biological uptake associated disturbance energy investment are main mechanisms impacting soil-dwelling animal development behavior. As highly hydrophobic, their presence among particles contribute water repellency influence availability. shown impacts crop plant growth, manifested effects properties biota agroecosystems. This review reveals process, impacts, agroecosystems could critical reference for risk assessment management.

The “Microplastome” – A Holistic Perspective to Capture the Real-World Ecology of Microplastics

Environmental Science & Technology, Год журнала: 2024, Номер unknown

Опубликована: Фев. 8, 2024

Microplastic pollution, an emerging pollution issue, has become a significant environmental concern globally due to its ubiquitous, persistent, complex, toxic, and ever-increasing nature. As multifaceted diverse suite of small plastic particles with different physicochemical properties associated matters such as absorbed chemicals microbes, future research on microplastics will need comprehensively consider their multidimensional attributes. Here, we introduce novel, conceptual framework the "microplastome", defined entirety various (<5 mm), found within sample overall toxicological impacts. novel concept, this paper aims emphasize call for collective quantification characterization more holistic understanding regarding differences, connections, effects in biotic abiotic ecosystem compartments. Deriving from lens, present our insights prospective trajectories characterization, risk assessment, source apportionment microplastics. We hope new paradigm can guide propel microplastic toward era contribute informed strategy combating important issue.

A critical review on plastic waste life cycle assessment and management: Challenges, research gaps, and future perspectives

Ecotoxicology and Environmental Safety, Год журнала: 2024, Номер 271, С. 115942 - 115942

The global production and consumption of plastics, as well their deposition in the environment, are experiencing exponential growth. In addition, mismanaged plastic waste (PW) losses into drainage channels a growing source microplastic (MP) pollution concern. However, complete understanding environmental implications throughout life cycle is yet to be fully understood. Determining potential extent which MPs contribute overall ecotoxicity possible through monitoring PW release MP removal during remediation. Life assessments (LCAs) have been extensively utilized many comparative analyses, such comparing petroleum-based plastics with biomass single-use multi-use alternatives. These typically yield unexpected or paradoxical results. Nevertheless, there still paucity reliable data tools for conducting LCAs on plastics. On other hand, impact so far not considered LCA studies. This due absence inventory-related regarding releases characterization factors necessary quantify effects MP. Therefore, this review paper conducts comprehensive literature order assess current state knowledge impacts that occur along strategies management LCA.
