Aspects of the sensitivity of juvenile Jasus lalandii and decapod excitable tissue to the water soluble fraction of crude oil
… (WSF) of crude oil is described. 2. The 24 hour median lethal concentration (LC50) of WSF of crude oil for 2 to 3 year old (30 - 45 mm cephalothorax length) juvenile Jasus lalandii ranged from 3,7 to 5,9 mg l⁻¹. 3. Behavioural experiments appear to provide a quick and convenient approach for …

The Influence of Water Quality Characteristics on Vanadium Toxicity to Model Aquatic Organisms
… levels of up to 7 mg/L in “treated” OSPW, a concentration that is toxic to aquatic organisms. Little information is available on how common water quality variables affect the toxicity of V to aquatic organisms. Furthermore, there is no clear understanding of the mechanism(s) of toxicity of V …

Insecticide detoxification in the navel orangeworm Amyelois transitella (Lepidoptera: Pyralidae)
… and methoxyfenozide had no effect. Results from median-lethal concentration (LC50) assays revealed that resistance was maintained across eight generations in the laboratory. Life history trait comparisons between the resistant strain and susceptible strain revealed significantly lower pupal …

Phototoxic target lipid model for predicting the toxicity of polycyclic aromatic hydrocarbons and petroleum to aquatic life
… phototoxicity of single PAHs measured either as median lethal concentration (LC50) at a fixed duration of exposure or median lethal time (LT50) at a fixed concentration. The model accounts for differences in the physical and chemical properties of PAHs and test species sensitivities, as well as …

An Evaluation of Coating Material Dependent Toxicity of Silver Nanoparticles
… were observed in D. magna test exhibiting lethal median concentrations (LC50) for citrate-AgNPs, PVP-AgNPs, and BPEI AgNPs respectively as, 2.7, 11.2, and 0.57μg/L. Median inhibitory concentrations (EC50) for MetPLATE tests were 1.27, 1.73, and 0.31mg/L respectively with significant …
