    Efecto de las actividades antrópicas sobre las características fisicoquímicas del rio Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Química, 2021) Garcés Alvear, María Fernanda; Pérez Aldaz, Lander Vinicio
    The objective of the research is to determine the effect of anthropic activities on the physicochemical characteristics of the Ambato River, through quality parameters that allow estimating the level of contamination of the river, for this a sampling network and monitoring plan were established in two phases, carried out in 2020 and 2021, taking 10 monitoring points along the micro-basin of the river, starting with the Marcopamba sector (high slope area) to the Viñas sector (low slope area). The evaluation of the physicochemical characteristics was carried out under standard methods, considering the maximum permissible limits of the Environmental Quality Regulation (TULSMA), in turn, the contamination was evaluated through the NSF Water Quality Index (WQI) and finally the data were correlated by means of an Anova statistical analysis. The results of the measurements of physicochemical parameters were found above the permissible limit, highlighting the highest values in dissolved oxygen (8,4 and 7,6 mg/L), turbidity (118 and 193 NTU), phosphates (2,1 and 0,9 mg/L), color (94 and 144), suspended solids (284 and 958 mg/L), heavy metals such as cadmium (> 0.02 mg/L), nickel (> 2 mg/L), lead (7,4 and 6,5 mg/L), magnesium (> 2 mg/L). From the foregoing, a regular and poor water quality was estimated in the different sampled areas, most affected by different anthropic factors, mainly domestic and industrial water discharges. Finally, this made it possible to indicate a progressive deterioration of the Ambato River in an annual period, in addition to suggesting constant evaluations of the quality of the water resource. waters.
