Particles from tires are a major fraction of microplastic pollution. They contain wide range chemical additives that can leach into the water and be harmful to aquatic organisms. In this study, we investigated acute toxicity tire particle leachates in early life stages three keystone echinoderm species (Paracentrotus lividus, Arbacia lixula, Diadema africanum). Embryos were exposed for 72 h leachate dilutions, prepared using concentration 1 g L-1. Larval growth, abnormal development, mortality measured endpoints. Furthermore, estimated activity glutathione S transferase (GST) electron transport system (ETS) P. lividus. Strong concentration-dependent responses observed all species, though with differing sensitivity. The median effect concentrations development lividus A. lixula 0.16 0.35 L-1, respectively. D. africanum, overshadowed lethal was 0.46 Larvae significantly smaller than control 0.125 while other two affected 0.5 ETS did not change but there non-significant trend increasing GST Seven organic chemicals eight metals detected at elevated leachates. While regard zinc as strong candidate explain some toxicity, it expected exhibit cocktail leached may also contribute their toxicity. Our results emphasize importance multi-species studies they differ susceptibility We found negative effects close projections environment, which calls more research mitigation actions on these pollutants.

Investigating nanoplastics toxicity using advanced stem cell-based intestinal and lung in vitro models

Frontiers in Toxicology, Journal Year: 2023, Volume and Issue: 5

Published: Jan. 27, 2023

Plastic particles in the nanometer range–called nanoplastics–are environmental contaminants with growing public health concern. As plastic are present water, soil, air and food, human exposure via intestine lung is unavoidable, but possible effects still to be elucidated. To better understand Mode of Action particles, it key use experimental models that best reflect physiology. Novel assessment methods like advanced cell several alternative approaches currently used developed scientific community. So far, cancer line-based standard approach regarding vitro nanotoxicology. However, among many advantages lines, there also disadvantages might favor other approaches. In this review, we compare stem cell-based lung. context nanoplastics research, highlight come cells. Further, specific challenges testing discussed. Although can demanding, conclude that, depending on research question, cells combination strategies a more suitable than lines when comes toxicological investigation nanoplastics.
