Deep-sea coral Lophelia pertusa laboratory maintenance and exposure to barite using water recirculation systems

Drilling activities usually discharge large quantities of fluids and drill cuttings, which are composed of fine particles, such as barite, that can physically affect Lophelia pertusa. An experiment to assess the effects of barite smothering on L. pertusa was conducted with a water recirculation system. The corals were collected in Santos Basin, Brazil. The experiment was conducted in 23 L cone-shaped aquaria, adapted...

Hepatotoxic and neurotoxic effects of combined lead and di-(2-ethylhexyl) phthalate exposure: Activation of total -, Ca2+- and Na+K+- ATPases in the liver of male rats

Lead and di-(2-ethylhexyl) phthalate (DEHP) are common environmental toxicants of concern around the world. Although effects of individual exposures to both agents are well documented, there is a dearth of information on the effects of co-exposure to both agents. In this study, combined exposure to lead and DEHP was investigated for effects on ATPase activities in the liver, brain and kidney tissues of rats. Male albino...
