The present bilateral project CONICET-FAPESP is the ideal complement to three already approved projects: PIP and PICT (type D), Argentina, AR-FAPESP, Brazil. The aim is to tackle the dynamics and the physical and chemical conditions in the neighbourhood of massive SFRs belonging to BCDs and AGNs. In particular, we want to focus our attention in the analysis of the way in which the massive stars and the active nuclei enrich and interact with the interstellar medium surrounding them and to study the global properties of the associated HII regions to be able to enlarge our knowledge up to intense SFRs detected in distant galaxies. We will performed a chemodynamical study of SFRs belonging to BCDs using optical high spectral resolution spectroscopy and photoionization models built with the Cloudy code. We will also use photoionization models in order to reproduce the observational intensities of the narrow lines in AGNs in the optical and ultraviolet spectral regions. Once the models describe the observational data, we can obtain calibrations among abundances of various elements using the intensities of the emission lines, as well as investigate the chemical evolution and physical properties of SFRs and AGNs in a wide range of redshifts.
