                         (1999 2008) and Particulate Matter (PM) data from Environmental 
                         agency of Sao Paulo State (CETESB) for the same period, were 
                         examined in order to look for the influence of urban effect and 
                         weekly cycles in lightning activity over Metropolitan Region of 
                         S{\~a}o Paulo (MRSP). The results show that there is a 
                         significant weekly cycle in PM10 10 over the MRSP and lightning 
                         activity (CG lightning) on area involving the MRSP, Campinas and 
                         Sao Jose dos Campos regions, both with reduction on the weekend. 
                         Besides, was found a significant weekly cycle in number of day 
                         with lightning over MRSP. We also examined the average number of 
                         flash per storm and air temperature in three different ranges of 
                         PM concentrations. For the first one, there is an increase of the 
                         average number of flash per storm from low to intermediate range 
                         and a trend to decrease from intermediate to high range. However, 
                         the air temperature tends to stay the same in all ranges. These 
                         results suggest that the pollution tends to saturate the 
                         intensification of storms and lightning activity in a specific 
                         level. After that, the increase of aerosols provided by pollution 
                         tends to decrease the lightning activity.",
