A laboratory method for evaluating wood preservatives should provide in a comparatively short time an integrated measure of the relative permanence and fungus-inhibiting capacity of a product. There is as yet no generally acceptable laboratory method of this type. Systematic service records serve to bolster the reputation of established preservatives....
Research on chemicals used as pesticides has been intensified
because of current interest in the possible long range effects on the
biota. It is vitally important to understand the action of these
chemicals on the metabolism of animals and plants which have
direct or indirect contact with pesticides.
It has...
The extraction of pentachlorophenol (PCP) from pressure treated wood
wafers with supercritical carbon dioxide has been studied. Experimental data
were obtained for the effects of pressure (17.5 - 25.0 MPa), temperature (313 - 353
K), flow rate (1 - 3 ml/min at supercritical conditions), and sample size (0.8 x 10...
A study was conducted at the Pacific Cooperative Water Pollution
and Fisheries Research Laboratories, Oregon State University,
to determine the effects of pentachlorophenol (PCP) on the early developmental
stages of the steelhead trout (Salmo gairdneri). Experiments
were performed from May, 1965, through May, 1968, on the
survival, growth, and bioenergetics...
