The Study of Akali Metal Contamination in Road Side Soil

IL 3; Experiment 1 October 31, 1996 The Study of Akali admixture Contamination in Road Side Soil get up Six fault samples were taken from a passagewayside that was expected to phonograph recordinglose characteristic of route salt defilement. This contamination is characterized by the figurehead of magnesium, calcium and sodium. The relationship between akali alloy concentration and length from the pavement was examined and determined to be nonexistent. Additionally, atomic absorbtion and atomic electric arc spectroscopy were compared and and atomic absorbtion was found to be 1.89 times as sensitive as atomic emission. Introduction A crude proficiency in snow and ice removal on paths is the application of magnesium, calcium, and sodium chloride salts to the bulge of the road. When the ice melts it dissolves these salts and causes them to migrate into dirt that is adjacent to the pavement. Over time, the accumulation akali metal salts can tape transport the che mical profile of the soil which can lead to modify biological effects. Flame atomic spectroscopy provides a technique that can quantify metal concentrations in the extracts of the soil samples and hence examine the relationship between distance from the point of road salt application and akali metal concentrations.

Experimental Soil preparedness: Six surface soil samples were collected at the intersection of Cold leap out Lane and the exit behave of Interstate 83, in northwestern Baltimore city. These samples were collected at distances from the roadway of 0m, 2m, 4m, 6m, 10m, and 20m. These samples were dried in a convection oven at 110°C for over 24 hours thus crushed. Aliqu ots of approximately one g-force were weigh! ed and then extracted with 10.0 mL of 1M ammonium acetate. The extract was filtered with an inline filter disc with a pore coat of 5mm and then diluted to 100.0 mL. submissive: The extracts were analyzed for...
