An analysis of lead toxicity in the Hawaiian environment was conducted. It was determined that lead enters the environment as an industrial contaminant resulting from the combustion of leaded gasoline. The amount of lead absorbed by the plants in various parts of the Hawaiian Islands is reported. The disposition of lead in the sediments of canals and yacht basins was investigated. The methods for conducting the surveys of lead content are described. Possible consequences of continued environmental pollution by burning leaded gasoline are discussed.
Computer program predicts, from readily available meteorological data, concentration and dosage fields downwind from ground-level and elevated sources of toxic fuel emissions. Mathematical model is applicable to hot plume rise from industrial stacks and should also be of interest to air pollution meteorologists.
A postflight analysis is presented of the sequence which caused toxic gas to enter the cabin during repressurization for 30 seconds from manual deployment of the drogue parachutes at 18,550 feet to disabling of the reaction control system at 9600 feet. Results and conclusions are discussed.
The question is posed whether forced air flow should be incorporated into flammability tests as a relevant variable. A test apparatus is described which permits tests to be conducted on small test specimens in a forced flow which is (continuously) variable over flow velocities from zero to 300 feet per minute (1.52 m/s). The effects of air-flow rate and oxygen concentration on flame propagation rate, maximum smoke density, and pyrolytic product toxicity were measured for a single material and were statistically evaluated. Regression analysis was used to graph the resulting relationships. It is concluded that air velocity is an important variable for laboratory flammability testing.
Twelve samples of cellular polymers were evaluated in the course of developing test methods for toxic materials characterization. Six samples were flexible polyurethane foams, three were rigid polyurethane foams, two were high density rigid foams, and one was a modified polyimide foam. Some effects of formulation variables are discussed.
