Tire rubber chemicals reduce juvenile oyster (Crassostrea gigas) filtration and respiration under experimental conditions

Toxicity of Tire Particle Leachates on Early Life Stages of Keystone Sea Urchin Species

“…Furthermore, leachates of PVC plastic toys reduced larval growth, with EC 50 values between 3.3 and 14.3 g L − 1 (Oliviero et al, 2019). In juvenile oysters it was found that exposure to TWP leachates reduced their scope for growth by 57% at a concentration as low as 1 mg L − 1 due to reductions in clearance and respiration rates (Tallec et al, 2022a). Since we performed this experiment in the absence of food, differential feeding cannot be a cause for the observed decrease in larval growth.…”

“…Also, several studies found high concentrations of metals in TWP leachates (Capolupo et al, 2020;Halsband et al, 2020). While acute toxicity of TWP leachates as well as sub-lethal effects on behavior, development, feeding, reproduction, and biomarkers have been studied in copepods, rotifers, and bivalves (Capolupo et al, 2020;Halsband et al, 2020;Lehtiniemi et al, 2021;Shin et al, 2022;Tallec et al, 2022bTallec et al, , 2022aYang et al, 2022), the number of studied invertebrate species is still limited. Adverse effects of TWP leachates or the tire-derived compound 6PPD-quinone have also been reported for several fish species, resulting in impaired eye development, changes in swimming behavior and mortality (Brinkmann et al, 2022;Chang et al, 2023;Kim et al, 2023;McIntyre et al, 2021;Tian et al, 2021).…”
