<abstract> <p>The beneficial effects of <italic>Prosopis africana</italic> (PA) on human health have been demonstrated; however, its protective against heavy metals (HM) are not yet understood. This study evaluated the potential neuroprotective PA in cerebral cortex and cerebellum. To accomplish this, we divided 35 albino Sprague Dawley rats into five groups. Group I did receive either metal mixture (HMM) or PA. II received a HMM PbCl<sub>2</sub> (20...

Recently we investigated the heavy metal hazards of Nigerian smokeless tobacco products 'STP'. Since 'STPs' are advocated as safer alternatives to cigarets, public health implication should be ascertained. This is a risk assessment poly aromatic hydrocarbons 'PAHs' in used Nigeria. Thirty from different parts (South East, South West, Niger Delta and North Central) Nigeria were studied. The 15 PAHs assayed using gas chromatographic system (6890 series 6890 plus) equipped with quadrupole Mass...
