Genotoxicity Set Up in Artemia franciscana Nauplii and Adults Exposed to Phenanthrene, Naphthalene, Fluoranthene, and Benzo(k)fluoranthene

Polycyclic aromatic hydrocarbons (PAHs) consist of a group over 100 different organic compounds mainly generated by anthropogenic activities. Because their low water solubility, they tend to be accumulated in sediment, where degradation rate is very low. Few studies have been carried out so far investigate the effects PAHs on Artemia franciscana. easy manage at laboratory scale, but it not sensitive biological model considering traditional endpoints (i.e., mortality). In addition evaluating lethality nauplii and adults A. franciscana after 24 48 h, we focused genotoxicity potential phenanthrene (PHE), naphthalene (NAP), fluoranthene (FLT), benzo(k)fluoranthene (BkF). Results showed that FLT was most toxic both for h exposure. Real-time qPCR all toxicants, including BkF, which had no negative survival crustacean, were able switch gene expression nine genes. This work has important ecological implications, especially contaminated sediment assessment represent abundant marine environment, opening new perspectives understanding molecular pathways activated crustaceans.
