WebAbstract An equation is proposed for calculating phase equilibrium constants for petroleum cuts in terms of the constants for ethane and heptane and the volatility of the petroleum cut, and empirical equations are derived for determining each of these parameters. Authors: Zhvanelskii, I B; Platonov, V M Publication Date: WebJan 20, 2024 · As no single aromatic toxicity data are currently available for A. millepora, putative CTLBBs were modelled from the experimental EC/LC 50 values for each endpoint and the time-averaged...

WebJan 19, 2024 · The CTLBB is a measure of the chemical concentration present in the target lipid (expressed as micromoles per gram of octanol), which is considered the site of toxic action for narcosis. WebMar 25, 2024 · The calculated 48 h CTLBB of 47.1 ± 8.1 μmol/g octanol indicates that Artemia nauplii exhibited comparable sensitivity to other crustaceans. A steep concentration-response was found across all compounds as evidenced by a narrow range (1.0–3.1) in the observed LC 50 /LC 10 ratio. Differences in toxicokinetics were noted, and no impacts of ... WebJan 1, 2024 · Typically, the CTLBB is estimated by fitting calculated thresholds from multiple single hydrocarbon exposures (>2) to the TLM, and reducing residuals between the values and the TLM with the universal narcosis slope. detox from thc home remedies
