The identification of statistical associations between o m p a [ionsand the occurrence of cancer can be used to identify parricular agents which may lead to the development of cancer.

The following eight regulations were selected for review; Three NESHAPS regulations: Benzene emissions from maleic anhydride plants 1 9^ Benzene fugitive emissions (decisions for new and existing sources) Vinyl chloride (two source categories) Two drinking water regulations: Trihalomethanes Inorganic chemicals (arsenic, cadmium, chromium, and lead) Actions taken concerning three pesticides: Chlorobenzilate Ethylene dibromide (EDB - three uses) Dibromochloropropane (DBCP - eight uses) In these eight regulations, cost-effectiveness values for 22 separate regulatory decisions and alternatives to those decisions are calculated.

The data col lectively demonstrate that group migration occurs in catalytic intermediates leading to formation of carbonyl products.

Since this approach is a multipie-significance testing tech H 874 nique which should lead by chance to the finding ofapproximately one 'statistically signif H 873 icant' positive association, using a 90% (two-sided) confidence interval, for every 20 inde 876 pendent jobs, departments, or exposures considered, it is used here as an exploratory or 877 hypothesis-generating mechanism; the probability values and confidence intervals cited 878 throughout the paper are given only to show relative strength of associations. 879 Only those portions ofthe controls' work experiences which occurred during the time 880 the corresponding case was employed were considered in this analysis, since the matching 881 criteria selected controls with longer total work histories than the cases'.
