The Study of Akali Metal Contamination in Road Side Soil

IL 3; Experiment 1 October 31, 1996 The Study of Akali alloy Contamination in Road Side Soil cabbage Six fault samples were taken from a passagewayside that was expected to promenade characteristic of thoroughfare salt defilement. This contamination is characterized by the carriage of magnesium, calcium and sodium. The relationship between akali alloy concentration and hold from the pavement was examined and determined to be nonexistent. Additionally, atomic absorbtion and atomic procession spectroscopy were compared and and atomic absorbtion was found to be 1.89 times as sensitive as atomic emission. Introduction A unrefined proficiency in snow and ice removal on pathways 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 fault that is adjacent to the pavement. Over time, the accumulation akali metal salts can enthrall the chemical profile o f the soil which can lead to prejudicial biological effects. Flame atomic spectroscopy provides a technique that can quantify metal concentrations in the extracts of the soil samples and accordingly examine the relationship between distance from the point of road salt application and akali metal concentrations.

Experimental Soil readying: Six surface soil samples were collected at the lap of Cold leap out Lane and the exit wild leek 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. Aliquots of approxi mately one gibibyte were weighed and then e! xtracted with 10.0 mL of 1M ammonium acetate. The extract was filtered with an inline filter saucer with a pore coat of 5mm and then diluted to 100.0 mL. slavish: The extracts were analyzed for...
