In order to predict ecological safety conserning cocoa dust emission (SP2,5 and SP10), the mathematical modeling of its dispersion was performed considering the atmosphere turbulent diffusion. Necessary gravity sedimentation rate of cocoa dust for modeling was identified during the experimental
researches. Obtained results indicate the necessity of intensification of fine particles emission clean-up in the observed confectionery factory.

The analysis of the generation, recycling and landfilling of waste in Ukraine is carried out. Significant generation of various wastes leads to their storage on the ground surface, as it is the most widespread way of waste treatment in Ukraine. Frequently, the stored waste burns (waste heaps, waste coal, landfills), causing significant accumulation of hazardous substances in the environment.

The article describes the stages of professional formation and scientific priorities of Professor Yaroslav Adamenko. The main results of joint research with students on the procedure for assessing the environmental impact of technogenic-dangerous objects, as well as ecological assessment of urbosystems and hydro ecosystems are given. The following is a description of the main scientific research results and possibilities for their practical application.

The purpose of the study is to determine the levels of hazardous pesticides used in Ukraine and the world and to identify the most dangerous of them.

The main agrochemical manufacturers of Ukraine are analyzed and a list of active pesticide substances is made. The ecotoxic method has been used and the list of the most environmentally hazardous pesticides for the environment and humans has been established. The mechanism of increasing environmental safety by using different pesticides on agricultural lands with acid and alkaline soils is proposed.

The aim of the research was to reduce ecological danger caused by vehicles through the use of combined fuel and improved designs converters of exhaust gases. The use of obsolete structures of a catalytic analyzer on cars and the provision of periodic purging of catalytic units can significantly reduce soot emissions without making changes to the design of the engine. It was established that the use of a mixture of diesel fuel with biofuels (made involving waste) reduces the toxicity of exhaust gases by 30–35 % and saves hydrocarbons.

The purpose of this work is to improve the ecological state of water bodies and coastal area of the “Enerhoharant” LLC company by implementing a series of environmental measures based on research of their ecosystems and environmental-economic assessment that will enable largely to solve the problem of optimal use of natural resources for the recreational purposes.

The article presents the possibility of the development of science-based concept of integrated processes complex enterprises energy mix (alternative energy and polymer wastes). A review of the literature and the necessary articles written on the subject: as technologies and economies develop and become more complex, energy needs increase greatly; types and methods of alternative energy, as well as the possibility of calculating the basic set of main economic indicators are classified; identified possible areas of work in obtaining the necessary information and results.

This study aimed to improve the ways of risk assessment for environmental safety. The implementation of “Environmental safety passports of species” is of practical importance for effective risk assessment of individual species impact to the environment, humans and other living organisms. The classification schemes of International Union for Conservation of Nature for evaluating habitats, threats & stresses, use and trade, livelihoods of species were analyzed and adapted to the requirements of environmental safety.

Purpose. The purpose of research - the creation of effective systems for monitoring and quality control of copper-bearing ores and their products at the stages of mining and processing of nonferrous metallurgy flagship redistribution of Kazakhstan on "Zhezkazgan» "Kazakhmys Corporation" due to the wide use of modern nuclear-geophysical technology testing tools and hardware and analysis of ores and industrial products of their processing in which problems are solved highly effective environmental monitoring.
