PEQUENO LEDEZMA, Miguel Ángel et al. Analysis of suspended particles deposited on arboreal vegetation in northeastern Mexico. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.1, pp.205-213. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i1.1545.

The activities of vegetation removal generate an impact on the suspension of sedimentary particulate material. The study of the impact of these particles in areas close to the removal works allows a first approximation of a quantitative nature for environmental impact studies in areas where there are no records of the degree of affectation. The objectives were to evaluate the impact on the time elapsed between the distance of the emission zone and the direction of the wind with respect to the concentration of particulate material in the vegetation adjacent to the area altered by the removal work. The concentration of suspended particles deposited on adjacent tree vegetation during 2014 and 2015 was analyzed. 18 trees of three different species (Cordia boissieri, Acacia amentacea, Havardia pallens) were sampled at distances of 100, 350 and 700 m in northwest and southeast directions from the area of vegetation removal. The amount of sedimentable particulate material was determined in relation to the foliar dry matter. In the samplings of May 2014 and February 2015 there were no significant differences, while for September 2015 there was a difference, with the southeast address showing the highest amount of particulate sediment. It is concluded that the analyzed material is inversely proportional to the elapsed time of the removal of vegetation, and a greater sediment concentration is observed in the direction of the prevailing winds.
