Abstract: This work includes the study of the ability of pomegranate peel as adsorbent for two kinds of pesticides (Lambda cyhalothrin and Diazinon) from their aqueous solutions. The equilibrium contact time for the samples was determined. The effect of some factors on the adsorption process which was represented by the effect of acidity function was also studied. It was found that the best adsorption is at pH=2. The effects of the different temperatures within the range (313, 323, and 333K) were studied. The amount of adsorption for the pesticides is decreased with the increase of temperature; this indicates that the adsorption process is exothermic. Finally the study of the adsorption isotherms takes the (S-shape) according to Gile's classification for all the cases from (S2, S4) type which is following the freundlich equation for the adsorption.

Abstract: Water contaminants such as chemicals, household waste or microorganism are known to be dangerous to human health and other living organism, thus the basis for this study. The physico-chemical parameters and heavy metal contents of four different well water in Bunza, North Western Nigeria were analyzed. The pH of the well waters ranged from 4.31 - 5.9, Magnesium and Calcium content of the well water ranged from 4.54 - 5.40 and 53.58 - 66.42 mg/L, Cadmium content of the well waters ranged from 0.017 - 0.021 mg/l, the pH values and Calcium content obtained falls below the permissible limit of 6.50 - 9.00 and 150 - 200 mg/l respectively as given by WHO, while the Cadmium content was observed to be higher than the permissible limit (0.003 mg/L). This study infers that well water in the studied area may not be safe for human and animal consumption
