Plastic pollution is a global crisis, especially in the marine environment. Excessive consumption and unsound disposal are responsible for the constant accumulation of plastic waste, resulting in plastic litter and microplastic contamination on a global scale. Establishing a new global framework is regarded as a promising tool to address plastic pollution, including marine plastic litter. However, there is a need to raise awareness of the role of consumers at individual and national levels in reducing the use of unnecessary plastics and increasing the recycling of plastic waste. The global framework should incorporate aspects of the importance of consumption responsibility in solutions addressing the issue of plastic pollution.

When microplastics (MPs) enter water bodies, they undergo various transport processes, including sedimentation, which can be influenced by factors such as particle size, density, and interactions with other particles. Surface waters contain suspended natural particles (e.g.

The issue of plastic pollutants has become a growing concern. Both microplastics (MPs) (particle size < 5 mm) and nanoplastics (NPs) (particle size < 1 µm) can cause DNA damage, cytotoxicity, and oxidative stress in various organisms. The primary known impacts of microplastic/nanoplastic are observed in the liver and respiratory system, leading to hepatotoxicity and chronic obstructive pulmonary disease.

Environmental pollution and health problems caused by traditional non-degradable fossil-based plastics are significant concerns, rendering green and renewable bio-based materials, such as cellulose and C-Priamine (1074), as attractive substitutes. In particular, the low plasticity of cellulose can be optimized using soft alkyl chains. Herein, multifunctional cellulose-based materials were constructed via covalent adaptable networks using the Schiff base reaction of oxidized microcrystalline cellulose with varying aldehyde (dialdehyde cellulose (DAC)) contents and C-Priamine (1074).

Microplastics (MPs), as the crucial environmental pollutants, can be easily transported into the human body and accumulate in the liver. However, current studies mainly focus on acute exposure to MPs, investigations on long-term interactions with MPs alone remain limited. Thereby, we examined noxious properties of MPs and selected the most common polystyrene (PS) MPs as the research object, including unmodified PS MPs (PS-MPs) and positive-charged PS MPs (PS-NH) at 10 mg/L employing oral drinking water methods in mice for six consecutive months in vivo.

Plastic mulch films support global food security, however, their composition and the potential release rates of organic, metal and metalloid co-contaminants remains relatively unknown. This study evaluates the low molecular weight organic additives, metal and metalloid content and leaching from low density polyethylene (LDPE) and biodegradable plastic mulch films. We identified 59 organic additives, and non-intentionally added substances in the new LDPE films (39.
