Studies on the effects of gaseous ions on plant growth. II. The construction and operation of an air purification unit for use in studies on the biological effects of gaseous ions.
Air pollutants seriously interfere with the maintenance of unipolar ionized atmospheres required in experimenting with the biological effects of gaseous ions. The construction and operation of an air purification unit designed to reduce air pollution to tolerable levels are described; it has functioned satisfactorily in conducting experiments with plants and animals.
