摘要: Particles deposition in the main industrial zone of Sfax City (southern Tunisia) was studied by weekly monitoring particulate fallout instances at twenty sites from November 11, 2012, to April 15, 2013. Very high fluctuation those particle fluxes, ranging 0.376 9.915 g/m2, clearly observed. Spatiotemporal distribution deposited fluxes and exposure each site plumes (i.e., phosphate treatment plant “SIAPE,” soap industry “SIOS-ZITEX,” lead secondary melting “FP Sud”) indicated concomitant effects surrounding sources. In addition, highest seemed be associated with predominant strong cyclonic situations. Those rates exceeded levels recorded case stabilities, considered as responsible for pollutant accumulation.
