The report embodies results of chronic and acute tests which established 96-hr LC50 concentrations of hydrogen sulfide and lethal threshold concentration (LTC), defined as the concentration at which no deaths occur for 48 hours, and no-effect levels of the toxicant based on chronic test running up to 826 days. Six species of freshwater fish and eight invertebrates were tested at all life history stages. The problem of application factor to relate acute to chronic responses is discussed in connection with the various species and appropriate factors described for the organisms used.
