The aim of the current study was to assess multifaceted effects polycylic aromatic hydrocarbon phenanthrene, mainly used in colouring, explosive, and pharmaceutical industries, on physiology two bivalve species with economic value as seafood, namely, Mediterranean mussel Mytilus galloprovincyalis European clam Ruditapes decussatus. assessed how phenanthrene affected several biomarkers biometric endpoints both bivalves, based an vivo experiment silico approach. bivalves were exposed during four time slots (i.e., 7, 15, 21, 28 days) concentrations water (50 µg/L 100 µg/L). For R. decussatus, additional contamination sediment applied due their typical benthic lifestyle µg/kg µg/kg). significantly reduced ability tolerate desiccation Median Lethal Time, also inhibited activity enzyme acetylcholinesterase a time-dependent manner. catalase indicated that experienced oxidative stress first 21 days experiment. significant decline observed last week for M. supported depletion enzymes caused by phenanthrene. has toxicokinetic toxicodynamic properties, Overall, results obtained suggest decussatus can be sentinel monitoring studies environmental impact phenanthene marine ecosystems. significance our findings is fact ecotoxicology, little known about chronic effects, simultaneous use multiple bioindicators, interactions molecular modelling.

Combined effects of global warming and chlorpyrifos exposure on the annual fish Nothobranchius furzeri

Ecotoxicology and Environmental Safety, Journal Year: 2022, Volume and Issue: 248, P. 114290 - 114290

Global warming and environmental pollution threaten aquatic ecosystems. While interactive effects between both stressors can have more than additive consequences, these remain poorly studied for most taxa. Especially chronic exposure trials with vertebrates are scarce due to the high time- monetary costs of such studies. We use recently-established fish model Nothobranchius furzeri assess separate combined pesticide chlorpyrifos (at 2 µg/L 4 µg/L) a °C temperature increase. performed full life-cycle assessment evaluate fitness-related endpoints including survival, total body length, maturation time, fecundity, critical thermal maximum (CTmax) locomotor activity. Exposure slowed down male maturation, reduced fecundity impaired growth fish. increase did not affect any measured on its own, combination CPF an severely almost no offspring production. Together, findings suggest that climate change may exacerbate impact pollution, multiple should be considered predict how populations will affected by ongoing global change.
