This book was released on 1990 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report of a study on the environmental impact of vegetation management methods in a mixedwood cutover carried out from 1985-90. Vegetation management treatments included two rates of a granular formulation of the active ingredient (ai) hexazinone (PRONONE 10G, 2 and 4 kg ai/ha) and mechanical methods (double disking, disk trenching, brush saw) for site preparation and crop release. The impact of these methods on the vegetation composition, structure and dynamics was evaluated and data was developed for environmental impact, and residue and fate of hexazinone using residue analysis techniques. Herbicide application technology was also evaluated and the influence of hexazinone application was determined on the nutrient dynamics in plants and soil and mycorrhizae. Site preparation treatments were applied in the fall of 1986 and crop release treatments in the spring of 1989. Results presented in this report are mainly applicable to site preparation treatments involving fall application of PRONONE 10G and spring application of mechanical treatments.

Dost and published by [Victoria] Forest Practices Branch, BC Ministry of Forests. This book was released on 2003 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hexazinone is a broad-spectrum soil-active herbicide available for forestry uses. This paper reviews research reported in the literature concerning the toxicology of hexazinone and evaluates the risks to forest workers associated with exposure to hexazinone formulations. It first summarizes what is known about the behaviour of hexazinone in the body (adsorption, distribution, metabolism, excretion) and the acute & subacute toxicity of hexazinone. It then examines the herbicide's subchronic & chronic systemic toxicity, reproductive & developmental toxicity, mutagenicity, and carcinogenic potential; and studies of forest worker exposure to hexazinone. The final section assesses the overall health risks to forest workers associated with the use of hexazinone. Includes glossary.

This book was released on 1994 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the base line conditions at the 12 Acid Rain National Early Warning System (ARNEWS) sites in the Prairie Provinces and suggestions for possible improvements in the present ARNEWS protocols based on the base line data. Five sites were established in white spruce stands and seven in pine stands (three in lodgepole pine and four in jack pine). Soil and foliage samples were collected and analyzed for selected chemical properties. Vegetation analysis of the understory were determined at each location. The base line chemistry data and vegetation analysis are summarized for each site and the general conditions of the forest ecosystems at these sites were assessed based on these data.
