Acute Toxicity Testing of Pink Salmon (Oncorhynchus gorbuscha) with the Tire Rubber–Derived Chemical 6PPD‐Quinone

Environmental Toxicology and Chemistry, Volume 43, Issue 6, Page 1332-1338, June 2024.
Abstract N‐(1,3‐dimethylbutyl)‐N′‐phenyl‐p‐phenylenediamine‐quinone (6PPD‐quinone) is a widespread contaminant of emerging concern resulting from oxidation of 6PPD, which is an antidegradant substance added to tires. The recent identification of 6PPD‐quinone as the cause of acute mortality in coho salmon has quickly motivated studies on 6PPD‐quinone ...

Field and laboratory microplastics uptake by a freshwater shrimp

Ecology and Evolution, Volume 14, Issue 4, April 2024.
Microplastics are widespread pollutants, but few studies have linked field prevalence in organisms to laboratory uptakes. Our results highlight that microplastic uptake is widespread in field populations of shrimp and partly density dependent, with field concentrations corroborating uptake rates recorded in the laboratory.
