Secondary lead Wastewater from wood preserving processes that use creosote or pentschtorophenot.

Since this approach is a multiple-significance testing tech nique which should lead by chance to the finding ofapproximately one `statistically signif icant' positive association, using a 90% (two-sided) confidence interval for every 20 inde pendent jobs, departments, or exposures considered, it is used here as an exploratory or hypothesis-generating mechanism; the probability values and confidence intervals cited throughout the paper are given only to show relative strength ofassociations.

It is highly possible that in humans, the metabolic pathway leading to the formation of the proximate carcinogen is not activated at low doses, where TCE is excreted by first-order kinetics.

At high doses, the metabolism of many chemi cals is likely to be saturated, a result which can lead to shifts in the relative importance of metabolic pathways and to relative in creases or decreases in the toxic response.
