increasing with time of exposure and the amount of spark energy deposited in the SF6 sample. Two cell lines have been tested, and both showed sensitivity to the toxic effect of the gas. Chemical analysis of the sparked gas revealed that the by-products formed, in order of most abundant to least abundant were SOF2 > SOF4 > S02Fs > SO2. Biological assays of samples of these individual by-products, or mixtures of these by-products at concentrations in which they were found in sparked SF6, were

The results were: (1) the individual by-products, at concentrations in which they exist in 1-16 kJ sparked SF6 samples, do not produce a significant cytotoxic effect; and (2) mixtures of the by-products have no cytotoxic activity. It therefore seems possible that some by-product, present in small amounts, might be determinative in producing the cytotoxicity of the sparked SF6 gas.
