Marine Plastic Pollution: Chemical Aspects and Possible Solutions

Summary

Reviewed plastic chemistry and how UV breaks C-C bonds into persistent microplastic particles. - 61463 — Biofouling changes microplastic sinking behavior, spreading them deeper into aquatic environments than density alone predicts. - 61430 — Heavy metals and microplastics co-detected in India's Hooghly River, highest near urban sewage outlets. - 61294 — Patent and bibliometric analysis of microplastic detection/remediation technologies across marine, freshwater, and soil environments. - 59338 — Microorganisms (bacteria/fungi) can break down plastic polymers via bioremediation. - 59296 — Even remote polar regions show microplastic contamination via atmospheric and ocean transport. - 59515 — Review of microplastic sampling methods; lack of standardization hinders cross-study comparison. - 59419 — Brazil's agricultural land degradation increases vulnerability to plastic and chemical pollution. - 59563 — Technical challenges in nano/microplastic chemical characterization; no standardized methods yet. - 59534 — Algae (phycoremediation) can capture microplastics from water as a low-cost treatment option. - 60977 — Wastewater treatment plants are a major microplastic source to waterways; current filtration is inadequate. - 55504 — Pullulan biopolymer as a biodegradable alternative to microplastic-generating synthetic packaging. - 68805 — Up to 14 million tonnes of microplastics estimated on the seafloor — 35x more than ocean surface. - 70753 — Oral microplastic beads accumulate in mouse liver, spleen, kidneys, and GI tract. - 74007 — Correction to atmospheric microplastic transport study; wind carries plastics to remote mountain areas. - 56736 — Microplastics absorb DDT strongly but have weak affinity for most current-use herbicides; PVC absorbs glyphosate. - 75099 — Freshwater microplastic contamination disrupts food webs and poses direct drinking water risk. - 27198 — AI/machine learning proposed to speed microplastic identification vs. slow manual methods. - 57768 — ML model predicts microplastic polymer aging rates, improving understanding of environmental breakdown. - 16750 — Comprehensive reference book on microplastic pollution sources, behavior, and environmental fate. - 58867 — Microplastics (up to 360/kg, mostly PVC) found in peat sediments in Vietnam's Long An province. - 77752 — German water research overview including microplastics as an emerging freshwater threat.
