The increasing global utilization of biodegradable plastics due to stringent regulations on traditional has caused a significant rise in microplastic (MPs) pollution aquatic ecosystems from products. However, the environmental behavior MPs remains inadequately elucidated. This study explored aging processes polylactic acid (PLA) and polystyrene (PS) under heat-activated potassium persulfate (K

Ecological and Health Risk Mediated by Micro(nano)plastics Aging Process: Perspectives and Challenges

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 19, 2025

Aged micro(nano)plastics (MNPs) are normally the ultimate state of plastics in environment after aging. The changes physical and chemical characteristics aged MNPs significantly influence their environmental behavior by releasing additives, forming byproducts, adsorbing contaminants. However, a systematic review is lacking on effects ecological human health regarding increasing but scattered studies results. This Review first summarizes unique methods for quantifying aging degree. Then we focused potential impacts organisms, ecosystems, health, including "Trojan horse" under real conditions. Through combining meta-analysis analytic hierarchy process (AHP) model, demonstrated that, compared to virgin MNPs, would result biomass decrease oxidative stress increase organisms lead total N/P greenhouse gas emissions ecosystems while causing cell apoptosis, antioxidant system reaction, inflammation health. Within framework risk assessment, used quotient (RQ) physiologically based pharmacokinetic (PBK) models as examples illustrate importance considering degree data acquisition, model building, formula evaluation. Given risks our urgent call more understand hazards real-world environments.

Ocean Rafting: Marine Litter and Benthic Stopovers Amplify Species Dispersal Opportunities

Global Ecology and Biogeography, Journal Year: 2025, Volume and Issue: 34(4)

Published: April 1, 2025

ABSTRACT Background Rafting of organisms on floating objects, long recognised as a key process in biogeography and evolution, has undergone tremendous change with the rapid increase ocean litter (plastics other human‐made materials). Resulting increases raft longevity abundance expand opportunities for marine species' dispersal. Here, we present conceptual framework role benthic stopovers by artificial rafts how these likely enhance cumulative species acquisition Stages Benthic Stopovers We define four stages stopovers: (1) landing (horizontal transport) or sinking (vertical transport), (2) retention habitat (intertidal subtidal), (3) colonisation local species, (4) re‐washing re‐surfacing transport). Colonisation Dispersal From The fate items their attached biota depends interplay (site‐related), regional (oceanographic/climatic) object characteristics. Available literature suggests that stopover events shores are most to happen complex natural environments like mangrove forests rocky shores. These can trap retain inter‐ subtidal zone, access suitable rafting species. Large highly buoyant items, rigid surfaces resistant breakage, complete stopovers. Conclusions dispersal increasing both pool frequency rafts. suggest far more common than currently reported play an range dynamics, calling innovative research address this knowledge gap.
