Abstract: The purpose of this research is to conduct a radiological survey of the crushing, milling, screening and conveyor unit of raw materials in the al-Qa'im fertilizer plant/General Phosphate Company, in order to calculate the absorbed doses of the workers in these places as well as the work hazards. As the raw materials in the phosphate fertilizer industry are extracted from the ground, Certainly contains radioisotopes such as the series of decay of uranium, thorium and potassium, which is the main cause of radiation activity in raw materials and the results of the dose absorbed to the workers in the unit of grinding, cracking and screening, And the conveyor belt for raw materials is (0.34, 0.38) mSv/y respectively, which is less than the internationally allowed limits (1msv/y) and the risk of working on working persons (1.7×10-5, 1.9×10-5) For crushing and crushing unit and belt conveyor unit, respectively, within the limits of internationally licensed 10-5.

Abstract: Water security and safety is of vital concern in Saki and the rest of the world. The aim of this was to screen major sources of water in Saki of potential pathogens of public health importance. Water samples of six different water sources were purposely collected aseptically from six different locations in Saki (well water, river water, rain water, borehole water, sachet water and bottled water); these were subjectsed to standard laboratory analysis. Four highly populated plates were sent for molecular characterization for Polymerase Chain Reaction and species sequencing for molecular identification. The highest total colony count was 70.0×10-5 from river water followed by rain water with the lowest of 0.1×105 CFU from borehole water. Molecular analysis identified amplification of isolates genes at 15000 base pair for river water and well water samples. The analysis showed that Klebsiella pneumonia (MN208186) and Enterobacter kobeii (KM593928) were the organisms found in rain water and river water respectively. The resulting nucleotide sequences was blasted at NCBI for pairwise comparison with existing data in the GenBank and their similarity was noted. The pathogenicity of the two isolates have been well-documented, making some of the water sources tested so unfit for human usage. Large-scale treatment of water sources are recommended before consumption viz-a-vis hygienic practices around water bodies.
