This work was carried out to evaluate the heavy metals (Cr, Cd, Fe, Ni, Mn, Pb and Zn) pollution load health risks population of some local fruit samples in Katsina state Nigeria. Results from this study have shown that except for mean concentration (1.152-1.623) Cd (0.053-0.092), (mg/kg) range values Fe (1.728-1.954), Mn (0.321-0.502) Zn (0.263-0.967 ppm) were generally below maximum allowable...
This study determined the daily intake of copper (Cu), lead (Pb), zinc (Zn) and mercury (Hg) in order to assess both carcinogenic non-carcinogenic risks caused by heavy metals Tilapia guineensis Lagos Lagoon. The were using flame atomic absorption spectrophotometer. metal distribution was Zn > Cu Pb Hg with values 0.0248±0.04, 0.0093±0.01, 0.0005±0.00 0.000±0.00 mg/kg respectively. Daily Int...

This study pointed to the assessment of the chemical composition (F, Ca, Mg, Na, K, Fe, Mn, Zn, Cu, Ni, Co, Cr, Cd, and carbohydrate) of different marine seaweeds (red, green, and brown) from the Egyptian Mediterranean Sea coast. The results showed that green seaweeds supplied better calcium sources than the red and brown ones. Also, red and brown seaweeds showed higher averages of Na and K tha...
This study was envisaged to explore the impact of pesticide solid waste leachate to Allium cepa (common onion) bulbs. Bulbs exposed to the leachate showed hampered root growth and morphological deformities. At 15% and higher concentrations of leachate after 5 days, gall like swellings were noticed around the mitotic zone (zone of root growth). From the dose response curve, the EC50 values for t...
