The Study of Akali Metal Contamination in Road Side Soil

IL 3; Experiment 1 October 31, 1996 The Study of Akali surface Contamination in Road Side Soil generalization Six fault samples were taken from a passagewayside that was expected to debunk characteristic of lane salt defilement. This contamination is characterized by the figurehead of magnesium, calcium and sodium. The relationship between akali alloy concentration and place from the pavement was examined and determined to be nonexistent. Additionally, atomic absorbtion and atomic dismissal 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 highroads 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 terra firma that is adjacent to the pavement. Over time, the accumulation akali metal salts can shipping the chemical profil e of the soil which can lead to change biological effects. Flame atomic spectroscopy provides a proficiency that can quantify metal concentrations in the extracts of the soil samples and then examine the relationship between distance from the point of road salt application and akali metal concentrations.

Experimental Soil eagerness: Six surface soil samples were collected at the carrefour of Cold leap out Lane and the exit storm 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 approximatel y one thou were weighed and then extracted ! with 10.0 mL of 1M ammonium acetate. The extract was filtered with an inline filter dish with a pore coat of 5mm and then diluted to 100.0 mL. implemental: The extracts were analyzed for...
