Air pollution has a serious impact on human health. Deterioration of the air environment causes 7 million premature deaths annually. Despite the active implementation of various environmental programmes and technical resources aimed at preserving and protecting the environment from anthropogenic factors, over 90% of the world's population live in cities that do not meet the air quality recommendations of the World Health Organisation (WHO). Intense and constant technogenic load necessitates continuous monitoring of atmospheric air quality. Sufficient, systematic and representative information is needed to study the spatial and temporal distribution of substances in the air basin, to predict pollution levels and to make correct environmental decisions. Environmental monitoring is a tool for obtaining such information. In this work the analysis of influence of radioactive waste of nuclear power plants on a radiation level of environment is executed and the tasks of its ecological monitoring in areas of location of the enterprises of nuclear power industry are considered.

A highly microporous Cu-BTC (denoted as HKUST-1) was synthesized using a simple and rapid synthesis room-temperature method. The as-prepared HKUST-1 obtained at room temperature for 10 min exhibited a very high Brunauer-Emmett-Teller surface area of 1875 m2/g, pore volume of 0.789 cm3/g, and average micropore size of 7.84 Å. Based on this product, we successfully fabricated a conductive electrochemical sensor HKUST-1@PANI by polymerizing a conductive polyaniline polymer (PANI) around the metal-organic framework HKUST-1. Fourier transform infrared spectra and X-ray diffraction patterns support the formation of HKUST-1@PANI. Furthermore, scanning electron microscopy studies confirmed that PANI uniformly covered the surface of HKUST-1. We used the resulting material to build a new electrochemical sensor for the reliable detection of lead ions. The electrochemical response of the developed sensor towards ions was evaluated using differential pulse voltammetry. Under optimized conditions, linear detection was reproducible over the Pb2+ concentration range from 0.005 to 50 μM with a minimum detection limit of 5 nM. The sensor is practically usable in a wide variety of environments, as it is virtually immune to interference from other coexisting ions.
