Evaluation of atmospheric air pollutants during sweeping process

ABSTRACT

The study is carried out on the sweepers of Moharem Bey, El-Ibrahimia and Miami sectors in Alexandria city to evaluate their exposure to sand rising and its constituents [sulfates,chlorides, benzene soluble organic matter, lead and iron] resulting from the sweeping process with the effect of atmospheric transport and diffusion by means of portable personal samplers. As for the sand rising and its constituents benzens soluble organic matter, lead and iron, the sweepers of the first sector at exposed to the highest concentration for its industrial, conunercil and residential activities besides its high traffic density. The sweepers of the third sector are exposed to the lowest con centration of sand rising and its constituents benzene soluble organic matter, lead and iron as a result of the atmospheric transport and diffusion. The percentage of the exposure to both sulfates and chlorides was the highest for the sweepers of the third sector for being net to their main source the sea, while the lowest percentage was at the second sector for being away from the effect of both the sea and industrial activities of the first sector
