Geochemical Survey of Missouri: Plans and progress for sixth six-month period (January-June 1972)

This is the sixth in a series of reports issued at six-month intervals describing current results of a reconnaissance geochemical survey of the State of Missouri. The survey was begun in July, 1969 and is intended primarily to provide epidemiologists of the Environmental Health Surveillance Center of the University of Missouri with geochemical information in support of their studies on the role of environmental factors underlying human and animal health. Secondarily, the survey is regarded as a pilot venture in the area of environmental geochemistry of large and geologically diverse regions.
