Urinary stones a worldwide problem for affecting more number of people. The urinary stones which formed to the deposition of few minerals & crystalline materials. Urinary stone samples are analyze by X-ray diffraction and electron microscopy. The present study have been to identify the minerals and elements, those are present in urinary stones and attempt to establish its morphological structure and elemental compositions. In the present study the minerals and morphological changes of different samples of human urinary stones are evaluated using XRD & SEM methods and the relationship with river water. The urinary samples are analyzed to identify the concentration of elements such as it Ca, Cu, Fe, K, Mg, Na, P, S and Zn by EDX method, also study some physical and chemical properties of river water and the relation with kidney stone formation.

The results of water examinations for Al-Najaf sea by used energy dispersive x-ray and laboratory examination and it compare with river water were pH value was 5.5, Chlorides 950 mg/l, Sulfate 834 mg/l and intractability of water was 811mg/l, for water samples from Al-Najaf sea. While were the results for the river samples of water in Al-Najaf city, it were pH value was 6.7, Chlorides 344 mg/l, Sulfate 290 mg/l and Intractability of water was 390 mg/l. The laboratory results showed the role of Trichoderma harzianum in reducing the clear pollution factors in the pollutant waters after detecting it with an electron microscope. Where the results of the biological treatment by Trichoderma harzianum showed that there clear significant differences between the initial tests for the pollutant waters of AL-Najaf sea and the sea waters that were treated as follows : pH value was 6.4, Chlorides 720 mg/l, Sulfate 400 mg/l and Intractability of water was 460 mg/l, for pollutant waters after treatment by Trichoderma harzianum.

This study used chitosan-g-poly (acrylic acid-co-crotonic acid) hydrogel (Ch-g-P(AA-CA)) as an adsorbent to remove aqueous solutions of lead ion (Pb (II)). A flame atomic absorption spectrophotometer was used to estimate the ion’s adsorption amounts. Metal ion concentration, pH, existing salt, and temperature were all studied. A gile’s classification indicates that these isotherms are of the L-curve type, and the experimental data were best fit by Langmuir and Freundlich isotherm models. At various temperatures (15, 20, 25, and 30°C), adsorption and various thermodynamic parameters (ΔH, ΔS, and ΔG) were studied. It was found that the adsorption process was not spontaneous, based on the thermodynamic parameters of the metal ion-ch-g-P(AA-CA) hydrogel systems. Ch-g-P(AA-CA) hydrogel adsorption increased as the pH of the solution rose and decreased as the ionic strength rose, according to the study’s findings.

The main routes of exposure to lead are eating food, adsorbing the skin, drinking water, and breathing the air. This exposure causes many of human health problem. Bioremediation is an ecofriendly, effective and has greater public acceptance. 'The bioremediation process was carried out using Saccharomyces bloulardii' yeast and lead at concentration of (0.1,0.2,0.3 mg/ml) under PH=7 condition at 35°C and for a period (24,48,72 hours), and anatomic absorption spectroscopy was used to analyze the concentration of lead after the completion of the treatment process. The results indicate that the highest removal of lead was % at 0.1 mg/ml and lowest removal by 0.2 mg/ml, and the best elimination period was at 72 hours.

Four samples were collected from different agricultural soils, as the isolates were isolated from these samples, namely Bacillus cereus, which were identified based on phenotypic characteristics and molecular diagnosis. The bioremoval process was carried out using Bacillus cereus and cadmium at concentrations (0.5, 0.2, 0.1 mg) at a temperature of 37 ° C and pH 7 for a period (72,48,24 hours), as the results showed that the highest removal of cadmium was 86% at a concentration of 0.1 mg / ml and the lowest removal was 34% at a concentration of 0.5 mg / ml. This study included the effect of the incubation period on removing heavy element ions, and it was found that the best period was 24 hours compared to 72 and 48 hours .
