From: Oxidative stress and immunologic responses following a dietary exposure to PAHs in Mya arenaria
Effects of dietary exposure to PAHs on the number of hemocytes. Results are expressed as the mean number of live hemocytes (104) per 12 clams, in hemolymph collected from control and contaminated organisms. Organisms were exposed to PAHs during 9 days and the contamination was stopped for the remaining 36 days. Significant differences between control and contaminated clams are represented by * for P < 0,05. Error bars represent S.E.M.
