Three successive generations of the marine polychaetous annelid Neanthes arenaceodentata taken from a laboratory population, were continuously exposed to one of three sublethal concentrations of No. 2 Fuel Oil water-soluble-fraction (WSFs). During each generation larvae, juvenile, and immature adult polychaetes were challenged with acute (96 h) doses of No. 2 Fuel Oil or south Louisiana crude oil WSF to test their sensitivity to petroleum hydrocarbons (PHCs). Larvae from all 3 generations, at all exposure concentrations, were no different from control (susceptible) larvae in their sensitivity to the two test oils. F1, F2, and F3 adults exhibited equally increased PHC resistance (X2) compared to control adults. With the exception of F1 worms, removal from chronic exposure 7 or 14 days prior to challenge did not result in termination or reduction of resistance, implicating a genetic mechanism behind PHC resistance in N. arenaceodentata. Mechanisms responsible for resistance appeared unrelated to external permeability and/or excretion rates.
