Degradation Studies of Selected Bisphenols in the Presence of β-Cyclodextrin and/or Duckweed Water Plant
AI summary Read the abstract
The degradation of selected bisphenol compounds in the presence of oxidative agents was studied, evaluating how these plasticizer-related chemicals break down in environmental and treatment conditions. The findings are relevant to understanding the fate of plastic-associated endocrine-disrupting chemicals once released from plastic particles into water.
It is hoped that this may be used for the efficient removal of low-molecular-mass micropollutants using classical technological wastewater treatment processes modified by biomass and macrocyclic additives. This process needs to be optimized, but the results presented have revealed that such green chemistry technology, if successful, may be an interesting alternative for the selective removal of the micropollutants investigated from wastewater using classical adsorbents (e.g., carbons and carbon-related nanomaterials), particularly in terms of the worldwide problem with microplastic pollutants in the environment and food products.

Degradation of nanoplastics in aquatic environments: reactivity and impact on dissolved organic carbon
AI summary Read the abstract
This study examined the degradation of nanoplastics in aquatic environments, finding that UV radiation and reactive oxygen species break down nanoplastic particles and alter their surface chemistry. Researchers found that degradation products affect the toxicity and colloidal behavior of nanoplastics in ways distinct from their parent materials.
Microplastic-derived dissolved organic matter and its biogeochemical behaviors in aquatic environments: A review
AI summary Read the abstract
This review examines how microplastics release dissolved organic matter (MP-DOM) as they break down in water, and how these released chemicals affect water ecosystems. MP-DOM can interact with other pollutants and alter carbon cycling in natural waters, with the type and amount varying based on plastic composition and weathering conditions. Understanding what microplastics release into water as they degrade is important because these dissolved chemicals may have their own toxic effects on aquatic life and water quality.
Progress on the photo aging mechanism of microplastics and related impact factors in water environment
AI summary Read the abstract
This review examined the photo-aging mechanisms of microplastics in aquatic environments, finding that solar UV radiation drives oxidation reactions that alter surface chemistry, fragment particles further, and enhance their capacity to adsorb and release co-occurring pollutants.
Tossed at Sea: Plastic Degradation in Aquatic Environments
AI summary Read the abstract
This study examines plastic degradation in aquatic environments, reviewing how abiotic (UV, mechanical, thermal) and biotic (microbial) processes break down plastics in rivers and oceans, shifting concern from persistence alone to degradation byproducts including microplastics. The work updates the pre-2009 view that ocean plastics do not degrade, highlighting that degradation generates small particles and potentially harmful chemical leachates.
