Results showed that, within the test concentrations limits, total P450 content and SOD activity were very sensitive to the toxicity of Benzo pyrene. POD activity was elevated only when earthworms exposed to the maximum BaP concentration 10^(-2mgmL^(-1). CAT activity did not show any response to BaP exposure.
