TL;DR: In this article, a nonspecific mode of toxic action was found predominant in acute to acute to chronic cancer patients with a wide variety of organic chemicals, and was found to be more prevalent in acute and chronic cases.

TL;DR: In this article, a more mechanistic explanation for the prediction of photo-induced toxicity of polycyclic aromatic hydrocarbons (PAHs) was proposed, which is the result of competing processes such as stability and light absorbance which interact to produce a complex, multilinear relationship between toxicity and chemical structure.

TL;DR: In this paper, fathead minnows (Pimephales promelas) and oligochaetes (Lumbriculus variegatus) were exposed in the laboratory to sediment samples from the lower Fox River/Green Bay.

TL;DR: In this paper, the energy difference between the Highest Occupied Molecular Orbital and the Lowest Unoccupied Molecular Orbital (HOMO-LUMO gap), which can be computed directly from structure, was found to be the molecular descriptor that best distinguishes phototoxic compounds from non-phototoxic chemicals.

TL;DR: In this paper, the authors evaluated an organic carbon partitioning model for predicting bioavailability of the organophosphate chlorpyrifos in sediments, in support of the development of a sediment-quality criterion for the pesticide.
