A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the para compounds.
Possible explanations for the non-linearity...
The fish early-life stage (FELS) test (Organisation for Economic Co-operation and Development [OECD] test guideline 210) is the
primary test used internationally to estimate chronic fish toxicity in support of ecological risk assessments and chemical management programs.

The catchment-filter, soil erosion gage, macroprofile, and
spike and washer techniques for erosion measurement were compared
on six plots along a newly constructed logging road in the Oregon
Coast Range during the winter of 1965-66. Three plots were located
on a cut slope; three plots were on a fill slope....
The relative rates of hydrogen atom abstraction from a series of
13 homoaryl and heteroarylmethanes by t-butoxy radical were determined at 70°C. The attacking radical was photochemically generated
from di-t-butyl peroxide. A relatively small range of relative rates
(factor of seven) has been found among the compounds studied. The
relative...
