Plastic products are widely used around the world, but waste plastic is not reasonably managed and causes serious pollution. Biodegradable plastics (BPs) provide an alternative to conventional plastics, all BPs can be completely degraded under natural conditions. Instead, they may break down into microplastics (MPs) faster than posing additional threat soil environment. In this paper, definition, applications, degradation behaviors of BPs, including biodegradable (BMPs), reviewed, we comprehensively summarized eco-toxicological effects BMPs in ecosystems, terms physical chemical properties soil, nutrient cycling, bacterial fungal communities, flora fauna. The compound other pollutants were also addressed. results revealed that made different or more severely compared MPs. Overall, review aims address gaps knowledge, shed light on ecological soil. a perfect substitute solve pollution, further exploration should focus their generation, environmental behavior, impact whether cause harm

Global pollution by plastics derived from petroleum has fostered the development of carbon–neutral, biodegradable bioplastics synthesized renewable resources such as modern biomass, yet knowledge on impact ecosystems is limited. Here we review polylactic acid plastic with focus synthesis, biodegradability tuning, environmental conversion to microplastics, and microbes, algae, phytoplankton, zooplankton, annelids, mollusk fish. Polylactic a low weight semi-crystalline bioplastic used in agriculture, medicine, packaging textile. one most widely biopolymers, accounting for 33% all produced 2021. Although vivo, not completely degradable under natural conditions, notably aquatic conditions. disintegrates into microplastics faster than petroleum-based may pose severe threats exposed biota.

As microplastic pollution has become an emerging environmental issue of global concern, microplastics in aquaculture have a research hotspot. For safety, economic efficiency and food safety considerations, comprehensive understanding is necessary. This review outlines overview sources effects aquaculture. External inputs processes are Microplastics may release harmful additives adsorb pollutants environment, cause deterioration as well toxicological effects, affect the behavior, growth reproduction products, ultimately reducing benefits entering human body through products also pose potential health risks at multiple levels. Microplastic removal strategies used various countries reviewed. Ecological interception purification considered to be effective methods. In addition, strengthening management improving fishing gear packaging currently feasible solutions. proactive measures, new portable monitoring system remote sensing technology broad application prospects. And it was encouraged comprehensively strengthen supervision talent exchange construction laws regulations.

Bioplastics are materials that biobased and/or biodegradable, but not necessarily both. Concerns about environmental plastic pollution constantly growing with increasing demand for substituting fossil-based plastics those made using renewable resource feedstocks. For many conventional bioplastics to completely decompose/degrade, they require specific conditions rarely met in natural ecosystems, leading rapid formation of micro-bioplastics. As global bioplastic production and consumption/use continue increase, there is concern regarding the potential from However, actual extent their occurrence impacts remains unclear, insufficient mass concentration-based quantitative data due lack analytical methods. This study developed validated an method coupling pressurized liquid extraction pyrolysis-gas chromatography-mass spectrometry combined thermochemolysis simultaneously identify quantify five targeted micro-bioplastics (i.e., polylactic acid (PLA), polyhydroxyalkanoate, polybutylene succinate, polycaprolactone, adipate terephthalate (PBAT)) samples on a polymer-specific mass-based concentration.

Abstract The negative impact of plastic accumulation in aquatic ecosystems is a known and undeniable problem. However, while many the scientific community’s countermeasures against such target effects most common commodity plastics, consequences so-called ‘biodegradable’ plastics those are seldom discussed. After all, though their alleged biodegradability sustains widespread belief that they harmless to environment, because material’s fate determines its classification as biodegradable or not, classified do not fact meet required norms standards ecosystems. Furthermore, during past five years, community has shown degradation can generate bio-microplastics have similar worse than conventional microplastics (MPs). Against background, this review details latest findings regarding how influence thus cause adverse health living organisms and/or act vectors chemical pollutants. Beyond that, it identifies key aspects trends be investigated greater depth, including need consider wider variety develop systematic methods allow quantifying identifying remains pollutants species. Other worth considering include arrival mobilisation dynamics MPs oceans. ways which small animals fed by filtering (e.g. red crabs other zooplankton organisms) move through water column into food webs also merit attention, for ingested numerous species at different trophic levels, point bioaccumulation tissues considered factor toxicity. This closes with series recommendations perspectives future studies on ‘biodegradable plastics’

Polyglycolic acid (PGA) is an emerging biodegradable plastic material. Together with polylactic (PLA), PGA considered a suitable alternative to conventional plastics and has been widely used in biomedical food packaging industries. However, degradable continue face the drawbacks of harsh degradation environment long time, may harm human body. Therefore, our study focused on assessing effects microplastics PLA development neurobehavior zebrafish. The results showed that had little effect 3-10 hpf embryos. developmental stunting was observed a100 mg/L PLA-exposed group at 24 hpf. In addition, exposure decreased survival hatching rates, increased wakefulness, reduced sleep This indicates affect circadian behavior zebrafish by affecting brain-derived neurotrophic factor (BDNF). suggest induces toxicity, reduces voluntary locomotion, anxiety-like behaviors, impairs sleep/wake behaviors larvae. also suggests potentially toxic cannot be ignored biological require further research.
