Conventional pollution prevention strategies for the protection of natural waters usually entail a comparison of analytical results with water quality guidelines. This comparison is often compromised by the inability to identify fully the toxicants i

In this paper a toxicity-based approach was used to assess the quality of groundwater samples collected from gas plants in western Canada. The gas plants selected were typical of plants currently in operation and represent a cross-section of hydrogeo

Conventional pollution prevention strategies involve chemical analyses of environmental samples for priority pollutants (toxic substances listed by environmental regulatory agencies) followed by data assimilation. The latter usually entails a compari

Trembling aspen (Populus tremuloides Michx.), a common hardwood tree throughout Canada, is being harvested at increasing rates for use in paper and building materials. Piles of aspen logs have been observed to produce a dark, watery, acutely toxic le

In recent years, concerns have been raised that low concentrations of chemicals may alter the normal functions of the endocrine system, resulting in potentially significant adverse effects on growth, reproduction, and/or development. For domestic was

Use of chemical criteria in assessing the potential for adverse toxic effects in contaminated sites can under or overestimate the necessary level of site cleanup required. The use of ecotoxicity testing provides a more direct assessment of adverse en

Effects of ethylene, gibberellins, kinetin, nitrate, light, and temperature, each alone or combined with other factors, were studied on the germination of dormant seed of field pennycress (Thlaspi arvenseL. # THLAR). Treated seed were incubated at a

Although the use of hypochlorite to disinfect seeds is widespread, the effects on tissues isolated from them have been largely ignored. Disinfection of barley (Hordeum vulgare L. cv. Himalaya) half-seeds with hypochlorite solutions of ≥1.0% (w/v) a

The regulatory actions of light, temperature, and various nitrogenous compounds on germination of dormant Sinapis arvensis L. seeds were examined to evaluate possible strategies for manipulating germination of soil-bome weed seeds. These treatments,

Depending on the applied concentration, nitrate can either stimulate or inhibit germination of dormant seeds of Sinapis arvensis L. (wild mustard). Seed NO−3 levels that corresponded to the maximal germination frequencies recorded, ranged from 0.3
