Effects of fluoranthene on the growth, bioavailability and anti-oxidant system of Eisenia fetida during the ageing process

► The ageing rate of fluoranthene decreased fast followed by slow with ageing time. ► Earthworms' intestine accumulated more fluoranthene than epidermis. ► The activities of SOD, POD, PPO and content of MDA in earthworms decreased gradually. ► CAT activity decreased initially, and then increased over 0-115 days.
