Deterioration of air quality due to the increase in atmospheric emissions from biomass burning(BB)is one of the major environmental problems *** this study,we estimated the contributions of BB to PM_(2.5) concentrations in the municipalities of Soledad and Malambo located in the Colombian *** evaluation period ranged from February 24 to March 30,2018,a period with a high number of BB events recorded in the surroundings of the evaluated *** contribution of BB to the two sampling sites was estimated using the Hybrid Single-Particle Lagrangian Integrated Trajectory(HYSPLIT)dispersion model with forwarding trajectories from each of the burning points identified by satellite images(n=1089).The PM_(2.5) emissions were determined using the fire radiative power(FRP),obtained by remote-sensing data,and corresponded to the radiant energy released per time unit by burning *** average PM_(2.5) concentrations during the evaluation period were 19.91μg/m^(3) for Soledad and 22.44μg/m^(3) for *** average contribution of BB to these municipalities was 22.8%and 28.8%,*** methodology used in this study allowed to estimate the contribution of this important source without knowledge of a previous tracer of BB,thereby increasing the use of the proposed procedure *** information would enable the implementation of effective mitigation,thereby diminishing the adverse impact of PM_(2.5) on the health of the population.

In this paper, wavelet transform and entropy are evaluated using the mathematical analysis concepts of reflexibility, regularity and series obtention, these concepts remark the reason to make a selective reference framework for power quality applications. With this idea the paper used the same treatment for the two algorithms (Multiresolution and Multiscale Entropy). The wavelet is denoted to have the most power full consistence to the light off the reflexibility, regularity and series obtention. The paper proposes a power quality technique namely MpqAT.
