Abstract |
Flow-through early-life-stage (ELS) toxicity tests were conducted with the pesticides aldicarb (Temik) and fonofos (Dyfonate) to determine their effect on the survival and growth of fathead minnows. Concentrations of 78 micrograms/L of aldicarb and 16 micrograms/L of fonofos did not affect survival and growth. However, 156 micrograms/L of aldicarb and 33 micrograms/L of fonofos were lethal to larval-juvenile exposed for 30 days post-hatch. The maximum acceptable toxicant concentration (MATC) of aldicarb and fonofos for the fathead minnow is estimated to be between 78-156 micrograms/L and 16-33 micrograms/L, respectively. The corresponding chronic values (geometric means of MATC values) would be 110 micrograms/L and 23 micrograms/L. Acute toxicity tests gave 96-hr LC50 values of 1370 micrograms aldicarb/L and 1090 micrograms fonofos/L. The acute-chronic ratio (96-hr LC50/chronic value) is 12 for aldicarb and 47 for fonofos. |
