This paper aims to determine the concentrations of heavy metals, specifically, arsenic, cadmium, copper, chromium, manganese, mercury, nickel, lead and zinc; in Auqui and Paria rivers in Ancash, Peru and compare it with the permissible maximum established limits by the World Health Organization (WHO) region.In order to obtain representative samples, a sampling plan in time and space was designed, that is, in each of the four (4) seasons (winter, spring, summer and fall) samples points were taken at five (5) (1000 m and 500 m upstream of the point of collection, the collection point at the entrance and exit of the treatment plant) in three (3) times (beginning, middle and end of the season). The response indicates that the Auqui River manganese concentration is above the maximum allowed limit (0,5 mg/L) and the Paria Riverthere is evidence that lead to think that heavy metal concentration...

El presente trabajo tiene como propósito determinar las concentraciones de metales pesados, específicamente, Arsénico, Cadmio, Cobre, Cromo, Manganeso, Mercurio, Níquel, Plomo y Zinc; en los ríos Auqui y Paria, en la región Ancash, Perú y compararlo con los límites máximos permisibles, establecidos, por la Organización Mundial de la Salud (OMS).A objeto de obtener muestras representativas, se diseñó un plan de muestreo en espacio y tiempo, esto es, en cada una de las cuatro (4) estaciones (invierno, primavera, verano y otoño) se tomaron muestras en cinco (5) puntos (1000 m y 500 m aguas arriba del punto de captación, en el punto de captación, a la entrada y a la salida de la planta de tratamiento) en tres (3) momentos (inicio, intermedio y fin de la estación).La respuesta obtenida indica que en el Río Auqui la concentración de Manganeso está por encima del límite máx...

En la presente investigación, se evaluaron las concentraciones de tres gases contaminantes del aire (H2S), (SO2) y (NO2) en el Relleno Sanitario, Cotuyoc bajo y Cochapampa para determinar la medida en que estos gases, contribuyen a la contaminación ambiental del distrito de Independencia. Para tal efecto, se muestrearon aire en tres puntos: punto de muestreo N° 01 ubicado en el Relleno Sanitario a una altitud de 3500 msnm; punto de muestreo N° 02 ubicado en Cotuyoc Bajo a una altitud de 3088 msnm y el punto de muestreo N° 03 ubicado en Cochapampa Bajo a una altitud de 3123 msnm. El tiempo estimado para la toma de muestras fue de 24 horas para el H2S y el SO2 y de 01 hora para el NO2, según protocolo del MINAM y la OMS. Las Variables Meteorológicas se midieron en el Relleno Sanitario y el Local Central de la UNASAM. Los análisis se hicieron en el laboratorio de Calidad Ambiental y...
