URBAN INDICATION IN THE AIR AND THE RIVER'S STATEMENT OF BERAT DISTRICT

Osumi River crossing the city of Berat, is originated from the mountains of Vithkuq at an altitude of 1,050 meters (3,440 ft) draining the region of south and partly in western lowland of Albanian Republic. Devolli River's source is in the southwestern corner of the Devoll municipality. It joins the Osum near Kuçovë, to form the Seman. The aim of this study is to assess the microbiological quality of the air around the urban area of Berat district which contributes to the river's statement and the quality of citizen's life. Sampling period was settled between 10:00 am?12:00 pm from June to August 2016 and each sample was performed on the sunny days with similar climatic conditions to reduce the measurement uncertainty resulted from weather variations. Technique applied to assess the air quality was the sedimentation technique as culture settling plates using plate count agar. Microorganisms were captured on Petri dishes with appropriate cultivation agars. After sampling, the agar plates were immediately transported to the laboratory for incubation. It was observed that meteorological factors influence on the variation of the concentrations of air borne bacteria, also air pollution contributes in the water quality of rivers of Berat district.
