From: Oxidative stress and immunologic responses following a dietary exposure to PAHs in Mya arenaria
Effects of exposure to PAHs on phagocytic activity of haemocytes. Results are expressed as percentage of haemocytes, collected from Mya arenaria, having engulfed one bead or more. 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.
