Abstract
There is a widely-held scientific conviction that the global climate is changing as a result of the combined anthropogenic forcing due to greenhouse gases, aerosols, and land surface changes.
Many pieces of evidence have concluded with a high degree of probability that human activities have exerted a substantial net warming influence on climate.
This study provides a comprehensive report on mass concentrations, statistical and geostatistical characterizations of PM10 atmospheric aerosols in the Gulf of Gabès, in south Tunisia.
Knowledge of source strengths and locations is also a valuable aid for interpreting observations and model results and ultimately choosing appropriate mitigation strategies. For these reasons we have developed a particulate matter emission inventory for Gabès for the year 2007.
After knowning the principal source of atmospheric aerosols in the Gulf of Gabès, which is the industrial complex, PM10 was measured at 18 locations (sample points in urban zones with industrial influence). Principally, they were located near the industrial complex (within a distance of 1000-6000 meters), with a mobile monitoring unit equipped with real-time analysers, which generated a mean value of each pollutant for an interval of 15 min. The duration of this measurement campaign was 20 days successive in 2007.
In this study, statistical and geostatistical techniques were used to estimate PM10 atmospheric pollution throughout the experimental area. After analysing data and obtaining a good variogram, multivariate data analysis, cartography via ordinary kriging, was used to estimate PM10 concentration at unsampled locations.
