TABLE 1. Alphabetical list of 3, 939 compounds with the results obtained 

 in preliminary screening tests of each substance. 



EXPLANATION OF TABLE 



Chemical nomenclature follows generally the Chemical Abstracts 

 system; certain exceptions are noted in the text. Sources of compounds as indicated 

 in the columns headed "Subm. " may be identified in Table 4. Submitters code 

 numbers are those used by the suppliers to identify their own materials; those known 

 to us are listed herein. 



Tests at indicated concentrations were conducted for a 24-hour 

 period at a water temperature of 55 deg. F. Formulated materials were tested at 

 the routine concentrations used without regard for the proportion of active 

 ingredient (s) present in each. 



Figures given indicate time in hours, fractions of hours, or minutes 

 ("m. ") to produce death or obvious distress and are the average response for each 

 species (where illness only was observed during the test period, the average time 

 to produce this response is underlined); an "n" indicates that no effect of the chemical 

 was observed; a dash indicates that the test was not performed; the names trout, 

 bluegill, and lamprey larvae are abbreviated T, B, and SL respectively.
