Detection of heavy metals and evaluation of beef procured from the different market of Dhaka in Bangladesh (Published)
The study was conducted to appraise the quality of beef via detection of heavy metal contents. Twenty markets were selected randomly from the Dhaka city corporation (DCC) of Bangladesh. Beef samples were collected from the selected market of DCC by two phases during study period. In first phase, fifty beef samples were collected from ten markets by purchasing to detect the heavy metal contents i.e chromium (Cr), cadmium (Cd), lead(Pub) and arsenic (As) in this study. In second phase, another fifty samples were collected from different ten markets of DCC to detect similar metal content as did in first phase. A total of 100 meat samples was collected from the selected market and analyzed to determine the concentration of toxic metals (Cr, Cd, Pb, As) in meat samples. In first stage, except for As (P>0.05) , all other metals (Cd, Cr and Pb) collected from different markets affected significantly (P<0.01) between treatments . In second phases of experimental study, all the detected metals (Cd, Cr, Ob, As) measured in this study differed significantly (P<0.01) between treatment. It can be concluded that the quality of beef of different markets appears to be good based on the chemical evaluation, even though variation was found in the toxic metal contents of meat samples in this study. The analyzed values of toxic metals in beef samples are within the range or limits of the acceptable level, so no health hazard will create over the consumer world through after consumption of beef.

Assessment of the Impact of Gas Flaring on the pH, Cd, Pb, Cu, Zn, Fe and Mn Concentrations in the Rainwaters of Jeddo Community, Delta State, Nigeria (Published)
This paper is focused on the possible impact of gas flaring on the pH, Cd, Pb, Cu, Zn, Fe, and Mn concentrations in the rainwaters of Jeddo community, Delta State, Nigeria. The Rainwater samples were collected from two locations in the community. The samples were then taken to the laboratory for analyses. The result for the pH for both samples of Rainwater 1 (R1) and Rainwater 2 (R2) (which are 6.20 and 6.00 respectively) showed that their pH did not comply with the acceptable limits of World Health Organization (WHO, 2003), National Environmental Standards and Regulations Enforcement Agency (NESREA, 2011), Department of Petroleum Resources (DPR, 2002) and Nigerian Standard for Drinking Water Quality (NSDQW, 2007). The result also showed that Cd, Pb and Mn all complied with WHO (2003), NESREA (2011), DPR (2002) and NSDQW (2007) domestic/recreational water quality limits; while the values of Cu, Zn and Fe metals generally did not comply with the safety standards.
