Abstract:The primary objective of this study is to determine the environmental impact of SDD2 by utilizing laboratory animals to evaluate its toxicity and by monitoring the behavior of SDD2 in the aquatic environment in terms of its degradation by microorganisms and adverse effect on aquatic animals. The investigation includes a series of short-term toxicity tests and a comparison of the data with the known deicer, Calcium Magnesium Acetate (CMA) to evaluate the capability of SDD2 as a potential deicer. The following experimental tests have been performed to investigate the basic behavior of SDD2 in the biological system: Acute Dermal Toxicity Test, Primary Dermal Irritation Test, Acute Inhalation Toxicity Test, Fish Acute Toxicity Test, and Biochemical Oxygen Demand Test. It is hoped that the results of this study would provide detailed preliminary information of the basic effect of SDD2 on the biological system and of its feasibility as a deicer in the environment.
