Abstract
La investigación sobre la calidad ambiental de los humedales de Villa María – Chimbote, se realizó entre enero y diciembre del 2015, en tres estaciones de muestreo. Se determinó los principales parámetros físicos y químicos, registrándose promedios de temperatura en 23.79 °C, oxígeno disuelto en 3.97 mg/L, solidos suspendidos totales en 1.90 mg/L, pH en 7.46, conductividad eléctrica en 932.33 μS/cm, salinidad en 11.34 ppt y la transparencia en 49.58 cm; se recolectaron muestras de agua para analizar bioindicadores de calidad ambiental como: fitoplancton, perifiton, así como muestras de macroinvertebrados y de macrófitas acuáticas, las cuales fueron identificadas con claves taxonomías especializadas y con ayuda de especialistas del Herbarium Truxillense; además se realizó la observación de peces y avistamiento de aves; determinándose de acuerdo a los Estándares de Calidad Ambiental (ECA) para aguas, que los humedales de Villa María - Chimbote se encuentra dentro de la categoría 1 y 4, clasificada como aguas superficiales para uso recreacional y para la conservación del ambiente acuático.
This research was carried out from January to December 2015, in three sampling stations. Physical and chemical parameters were determined. The average values were: temperature in 23.79 degrees Celcius, dissolved oxygen in 3.97 mg/L, total suspended solids in 1.90 mg/L, pH in 7.46, electric conductivityin 932.33μS/cm, salinity in 11.34 ppt and transparency in 49.58 cm; water samples were collected in order to identify environmental quality bio-indicators like phytoplankton, periphyton, macroinvertebrates and aquatic macrophytes, these samples were identified with taxonomic keys and specialists from the Herbarium Truxillense; also fish and bird wildlife were observed. Villa María - Chimbote wetlands falls into the first and fourth category according to the Water Environmental Quality Standards, being classified as superficial waters for recreational use and aquatic environment conservation.
