Further dissociation of this product ion yielded ions at m/z 213, formed via neutral loss of CH3 (-15 Da), at m/z 187, formed via loss of propene
, and at m/z 145, corresponding to the dichlorobenzene ion in MS3 (Fig.

[CCl.sub.4] is produced industrially by the chlorination of methane, propane, ethane, propene
, or carbon disulfide and is soluble in alcohol and acetone and miscible with benzene, ether, and chloroform and has been used as a grain fumigant, rodenticide and solvent for oils, fats, rubber cements, and resins. This was introduced in dry-cleaning because of the high cost of the earlier petroleum solvents and was used as a domestic spot remover.

The next group, by the number of incidents that occurred in the analyzed period, consisted of gases hazardous only due to their physico-chemical properties (group I), including: extremely flammable propane-butane (249 cases), methane (79 cases), propene
, acetylene, hydrogen (6-19 cases) and oxygen (5 cases) classified as an oxidant that may cause or intensify fire.

Sixty-two of the compounds exhibited strong absorption peaks, of which 13 are known or suspected carcinogens (including benzene, ethylbenzene, benzeneacetonitrile, acetonitrile, quinoline, isoquinoline, sterene, diethyl phthalate, 2-methylpyridine, naphthalene carbonitrile, and propene
) and more than 20 are known environmental toxins causing acute toxic effects on exposure (including carbon monoxide, p-xylene, phenol, toluene, benzaldehyde, benzenedicarboxylic acid [phthalic acid], and long-chain and cyclic hydrocarbons).
