The Study of Akali Metal Contamination in Road Side Soil

IL 3; Experiment 1 October 31, 1996 The Study of Akali metallic element Contamination in Road Side Soil regard Six fault samples were taken from a passagewayside that was expected to showing characteristic of pass salt defilement. This contamination is characterized by the comportment of magnesium, calcium and sodium. The relationship between akali alloy concentration and surpass from the pavement was examined and determined to be nonexistent. Additionally, atomic absorbtion and atomic run spectroscopy were compared and and atomic absorbtion was found to be 1.89 times as sensitive as atomic emission. Introduction A uncouth 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 footing that is adjacent to the pavement. Over time, the accumulation akali metal salts can broadcast the chemical profile of the soil which can lead to electronegative biological effects. Flame atomic spectroscopy provides a technique that can quantify metal concentrations in the extracts of the soil samples and consequently examine the relationship between distance from the point of road salt application and akali metal concentrations.

Experimental Soil facility: Six surface soil samples were collected at the point of intersection of Cold leap out Lane and the exit slope 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 ove n at 110°C for over 24 hours thus crushed.! Aliquots of approximately one gigabyte were weighed and then extracted with 10.0 mL of 1M ammonium acetate. The extract was filtered with an inline filter disk with a pore coat of 5mm and then diluted to 100.0 mL. subservient: The extracts were analyzed for...
