The utilization of fossil fuels is releasing previously carbon stored in the various carbon pools of the earth and increasing the global concentration of Carbon dioxide from an initial 280 parts per million in the 1850s to above 400 parts per million today. This review takes a look at previous works on carbon sequestration; its feasibility, potential and process. Increased carbon emission has disrupted the fragile balance in carbon content between the atmosphere and ocean which took thousands of years to attain.

An analytical study of the impact of solids contained in the air of urban areas on human health was conducted. Based on the analysis of the database of the Organization for Economic Cooperation and Development and the State Statistics Service of Ukraine on the emissions of substances into the atmosphere, it was established that the effects of solids on humans depend on particle diameter, morphological and physicochemical characteristics.

The life path and the range of scientific interests of Professor Oleksandr Moroz are described. The main results of scientific research in the field of the influence of vertical refraction on the accuracy of astronomical and geodetic measurements are shown.

At some sites of the sewage collector in Kharkov concentration of hydrogen sulfide in the underroof space exceeds in thousands of times daily average MPC. As a result the gaseous emissions from the sewage network in the city atmosphere the content of hydrogen sulfide in the atmosphere of residential development area may exceed the MPCd.a. The degasifier, installed above the sewage shaft efficiently rectifies gas releases. Design solutions are developed, which allow to harmonize degasifiers on sewerage nets with urban environment of different application.

Розглянуто досягнення та бар’єри у вирішенні проблем рефрактометрії – науки, що вивчає закони поширення електромагнітних хвиль (ЕМХ) в неоднорідній за густиною атмосфері Землі та планет. Описано внесок Львівської школи рефракції в цю науку та подальші завдання досліджень.
