Abstract. The paper carries out the research of nitrites-anions content in melt water of snow cover using the photometric method with Griess reagent. Samples were taken in the city of Chita and the surrounding area. In a series of experiments it was found out that the content of NO2- mainly depends on the position of the snow collection point, concentration of nitrogen oxides and dust in the air. The most polluted samples were taken near the roads. Comparison of the content of nitrogen oxides in the atmosphere on the basis of data obtained from two automatic quality monitors and the level of the melt water pollution with nitrites shows no significant differences.
Key words and phrases: снеговой покров, нитриты, оксиды азота, фотометрия, реактив Грисса, snow cover, nitrites, nitrogen oxides, photometry, Griess reagent
