TL;DR: A mass-balance model for the uptake of organic contaminants in the opposum shrimp (Mysis relicta) is developed and demonstrates higher concentrations in upper-trophic-level organisms by two effects: introduction of another trophic level in the food web, and increased benthic-pelagic coupling.

TL;DR: The characterization of the evaporation rate of complex hydrocarbon mixtures, such as commercial oil fractions, under environmental conditions is discussed in this paper, where it is shown that the relevant thermodynamic quantity is the total volume of vapour (per unit of initial oil mass) removed under isothermal differential distillation conditions (V m3/kg) as a function of the mass fraction of the oil remaining (F).

TL;DR: In this article, an effectiveness test for chemical oil spill dispersants was further developed and standardized, in which known volumes of dispersant and crude oil are contacted on the surface of seawater in a laboratory-scale vessel in which there is a circulating air current that imparts a swirling wave action to the water.

TL;DR: Rather than seeking to apply the hazard criterion of persistence to metal ions, the model can be used to deduce a critical loading that results in a defined toxic end point, thus integrating the hazard criteria of persistence, toxicity, and possibly, bioaccumulation.

TL;DR: In this article, a single pulse shock tube was used to study the reactions of nitrogen with methane, ethane and acetylene at 1400°-6000°K, and samples obtained through a quick-opening check valve were analyzed by gas chromatography.
