Johnny Horizon Environmental Test Kit.
Bentley, Richard; Bentley, William
Derived from tests presently used by state and federal agencies involved with pollution detection, this Environmental Test Kit contains materials and instructions for ten experiments. Each experiment is designed to test a different aspect of air and water, to find out whether or not the air and water in the tester's immediate area has been polluted by man. Air tests are for suspended particles, wind blown particles, nylon deterioration and smoke density. The water tests include coliform analysis, pH test, settleable solids, hydrogen sulfide, relative stability and phosphates. The test kit, which has been evaluated by the New York Department of Environmental Conservation personnel, would be useful at the junior-senior high school level after orientation and under instructor supervision, although it is intended for ages ten to adult. It can provide reasonably accurate tests for moderately to heavily polluted areas, but the user may experience some difficulty detecting pollution in marginal areas. Bearing the seal of the U. S. Department of the Interior and the image of the department's symbol, Johnny Horizon, the kit fills a need for those who wish to extend their concern for the environment into the monitoring area. (BL)
