“…After 96 h of treatment, LC 50 , LC 99 and NOEC values (acute test) were 183.70, 250 and 60 mg/L, respectively. A concentration dependent increase in mortality was observed and these results are in agreement with those described by Bernardini et al, in Xenopus embryos [27], i.e. based on LC 50 values, B. arenarum showed a similar phenol tolerance as this species (LC 50 178 mg/L).…”
