The distribution of three heavy metals (Cd, Zn, Pb) were detected in muscle and gills of two crab species namely Uca inverse and Metopograpsus messor, collected from Al-shogig coast Red Sea, during winter and summer 2008. Lead and zinc were most abundant in all crab tissues under investigation at both winter and summer. Zinc, lead, and cadmium recorded highest concentration levels in gills, and low in muscles. According to the previous studies, these value of concentrations are low, thus there is no risk yet for human or other marine organism consumption of flesh of these crabs.
Health status of printing press workers of Bhopal with regard to their clinical and haematological, blood iron, copper and zinc levels were assessed. Workers exposed to lead complained of headache, muscular weakness, abdominal cramps and manifested sign of anaemia, with low haemoglobin, iron, copper and blood levels in association of higher levels of lead. Children were found to be more susceptible for lead toxicity.

Thiosemicarbazide derivatives are well known for their bioliogical activities,1 Many thiadiazoles also possess potential fungicidal,2-6 hypotensive activity7, herbicidal,8 and pesticidcal activity.9 Keeping this in view, the titled compounds (1, 2) have been prepared following the reported procedure10-12, (scheme-1) and were tested for their antifungal activity. |
