Bioplastics are currently and increasingly used as substitutes of conventional plastics; furthermore, they mainly utilised in order to cope with problems related plastic-based pollution. Certified international standard methods identify the criteria a bioplastic must comply be labelled compostable and/or biodegradable. In addition, this is particularly case when operating under conditions that expected full-scale waste facilities. However, biodegradation natural environments occurs manifold different conditions, such aim research studies estimate extent which can biodegrade simulated conditions. For reason, specific indexes quantitatively degree degradation. present paper, description methods, assess biodegradability bioplastics environmental provided. By summarising results obtained by study, it concluded that: (i) biopolymers claimed biodegradable may not degrade plants due fact process industrial treatment cannot completely reproduced at lab-scale; (ii) static set representative dynamic processes occur or environments; (iii) experimental tests difficult compare one other differences multitude matrixes (i.e., inocula, soils, biopolymers).

Natural polymer-based nanocomposites have received significant attention in both scientific and industrial research recent years. They can help to eliminate the consequences of application petroleum-derived polymeric materials related environmental concerns. Such consist natural biopolymers (e.g., chitosan, starch, cellulose, alginate many more) derived from plants, microbes animals that are abundantly available nature, biodegradable thus eco-friendly, be used for developing agriculture food industry applications. Biopolymer-based act as slow-release nanocarriers delivering agrochemicals (fertilizers/nutrients) or pesticides crop plants increase yields. Similarly, biopolymer-based nanofilms hydrogels may direct product coating extend shelf life improve seed germination protection pathogens pests. Biopolymers huge potential food-packaging. However, their packaging properties, such mechanical strength gas, water microbial barriers remarkably improved when combined with nanofillers nanoparticles. This article provides an overview strategic applications polymer active compounds, hydrogels, nanocoatings nanofilms. risk, challenges, chances, consumers' perceptions nanotechnology production been also discussed.

Micro- and nanoplastics (MNPs) are attracting increasing attention due to their persistence potential ecological risks. This review critically summarizes the effects of photo-oxidation on physical, chemical, biological behaviors MNPs in aquatic terrestrial environments. The core this paper explores how photo-oxidation-induced surface property changes affect adsorption toward contaminants, stability mobility water porous media, as well transport pollutants such organic (OPs) heavy metals (HMs). It then reviews photochemical processes with coexisting constituents, highlighting critical factors affecting MNPs, contribution phototransformation other contaminants. distinct mechanism aged pointed out, terms toxicity organisms, biofilm formation, planktonic microbial growth, soil sediment community function. Furthermore, research gaps perspectives put forward, regarding underlying interaction mechanisms natural constituents under conditions, combined fate microbiological effect photoaged especially biotransformation pollutants.

Pollution due to microplastics and nanoplastics is one of the major environmental issues last decade represents a growing threat human animal health. In aquatic species, there large amount information regarding perturbation marine organisms; instead, are only few studies focusing on pathophysiological consequences an acute chronic exposure micro- in mammalian systems, especially reproductive system. There several that have described damage caused by plastic particles, including oxidative stress, apoptosis, inflammatory response, dysregulation endocrine system accumulation various organs. addition this, recently been found influence evolution microbial communities increase gene exchange, antibiotic metal resistance genes. Special attention must be paid farm animals, because they produce food such as milk, eggs meat, with consequent risk biological amplification along chain. The results indicate tissues, negative effects, but all effects body not ascertained, considering long-term consequences. This review provides overview possible adverse livestock assesses potential risks for disruption physiological functions.

Microplastics (MPs) are abundant in aquatic systems. The ecological risks of MPs may arise from their physical features, chemical properties, and/or ability to concentrate and transport other contaminants, such as per- polyfluoroalkyl substances (PFAS). PFAS have been extracted found natural waters. Still, there needs be a mechanistic investigation the effect chemistry water physicochemical properties on how partition onto secondary MPs. Here, we studied influence pH, organic matter (NOM), ionic strength, temperature adsorption generated PET bottles. was thermodynamically spontaneous at 25 °C, based Gibb's free energy (ΔG = -16 -23 kJ/mol), primarily due increased entropy after adsorption. Adsorption reached equilibrium within 7-9 h. Hence, will surface hours fresh saline Natural decreased capacity for through electrosteric repulsion, while higher strength favored by decreasing electrostatic repulsion. Increased pH which negated study provides fundamental information developing models predict interactions between PFAS.

The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver.
