Abstract. The article considers features of the method of atomic absorption spectrometry and its variants. Special attention is paid to the relevance and peculiarities of its application in monitoring the content of heavy metals in different environments on a local and regional level. With the help of KVANT.Z atomic absorptive spectrometer (the company-producer is KORTEK) the author determines the actual volume of inputs of heavy metals from a specific local source. The metallurgical Krasnyy oktyabr plant was chosen as such a local source. The determination of the actual concentrations of heavy metals covered the winter period 2016-2017 and included measurement of content of individual elements in the freshly fallen solid precipitation. Sampling of solid precipitation was carried out in the band interval of 50-1200 meters from the impact of the object on the basis of a triangulated irregular network. The results of measurements, for example total content of zinc, indicate the possibility of determining the qualitative elemental composition of the studied environments, a reflection of the number concentration of the specific element at each point of sampling. The obtained data of local monitoring allows to evaluate effectively the actual area of a specific local object impact. This is especially urgent for the urban environment.
Key words: atomic absorption spectrometry, heavy metals, local monitoring, environmental monitoring, steel industry.
