Study of the processes of radionuclides transfer, heavy metals and aero-particles among the solid, dissolved phase and the air

In this chapter the investigations developed in the Instituto Nacional de Investigaciones Nucleares (ININ) are presented, in collaboration with specialists in diverse fields of the science. In the first place, is presented the objective and an introduction of each one of the following projects: Study of the uranium migration through the not saturated area, and Synthesis and characterization of phosphate materials by conventional techniques, projects developed under the direction and collaboration of the Ph D. Eduardo Ordonez Regil. Identification of the chemical-morphologic composition of painting mural pigments: the blue Mayan, indigo blue, the secret of the color, and investigation of the physiochemical components of the asphaltenes and malthenes of heavy crudes and vacuum residual, with the supervision of the Ph D. Miguel Jose Yacaman. Evaluation of the water quality and type of sediments of the lake-crater The Pool: one of the seven stars of Santiago Valley, Guanajuato; Study of the sorption kinetics of Cr(Vi) in floor of a container of chromium residuals in Buenavista, Guanajuato, Mexico; Investigation of the underground water hydrochemistry of the basin of the Avenues River in Pachuca de Soto, Hidalgo, and Characterization of the particle material and modeled of the dispersion and pollutants transport in the air of the Metropolitan Area of the Toluca Valley, projects carried out under the direction and collaboration of the Ph D. Lazaro Raymundo Reyes Gutierrez. Finally, is presented the most representative of the obtained results, as well as a discussion of the same ones. (Author)
