Environmental and ecological studies concerned with the environmental impact of military activities upon the ecosystems surrounding DPG, and the safety of human communities and agricultural resources have continued and are reported in two volumes the first fulfilling mission tasks, the second on environmental impact studies. Accumulated data for baseline demography on selected, common rodents and jackrabbits have been analyzed in greater depth than they were previously. Epidemiology and toxicology information has been obtained from these native fauna specimens as well as from domestic livestock and wild horses. Methods of detecting tularemia have been improved. Determination of baseline erythrocyte acetylcholinesterase AChE activity levels in wildlife and livestock has been completed. No significant differences were found in levels of AChE by geographic area. The AChE levels in livestock were significantly higher in early spring than in fall collections, but wildlife exhibited minimal seasonal differences. These AChE baseline values have been applied to the investigations of known or suspected exposure events. No toxicolgical impact has been detected, but work will continue to determine the effect of organophosphorus on the environment.
