A simplified procedure using diffusion and a sulfide ion selective electrode is described for measuring acid‐volatile sulfides (AVS) in sediment This method yielded at least 10% more AVS than the more common purge‐and trap method The quantity of AVS (based on dry mass of sediment) was found to be dependent on acid concentration and on mass of wet sediment The mean recovery of known additions of sodium sulfide was 93 8 ± 6 7%
