Rainwater management is one of the important problems of cities. At very strong downpours, storm sewer systems may not capture the rainwater, which floods pavements and roadways. The water flushes fuel and oil traces after vehicles, fallen debris, and other pollutants, which will be moved to the ground, ponds, rivers, seas, etc. In past, the problems were solved using engineering approaches – a set of rainwater receivers, a duct network, and at best, wastewater treatment plants. Now, the sponge city concept is a better solution that uses a biotechnological way for throttling water flows, drainage, and purifying them. The work aims to improve the design of roads to fully absorb rainwater from them with maximum convenience for road users. We propose a design of roads using special “green structures” – rain-garden bands along the sides of roadways. We tested its ability of water capturing on the example of Kyiv city by matching the ability with the strongest precipitation observed. In addition, the proposed plants can extinguish the energy of bouncing cars during road accidents for the protection of pavements.

People modify 56% of the Earth’s land. The world trend is changing from rapacious to considered influence such as green construction/production. Nevertheless, the terroristic war of the Russian federation against Ukraine causes the chaotic destruction and snowballing emissions from shell bursts and fires. Reclamation of land should attempt to repair the hugely dangerous influence of this, especially in the temporarily annexed lands of Ukraine. Donbas was one of the most stressed regions due to active mining and other industries, and contained more than 38% of Ukrainian damaged lands. The war deepens the situation. The most natural reconstructive measure is greening. The authors analysed the requirements for greening to gain the maximum benefits. Enduring and effective plant assortments were proposed for the region. For sanitizing the environment, experiments were performed with phytoncide activity using a photographic paper method. It was found and recommend that new phytoncide plants - Japanese quince (Chaenoméles japónica) and barberry (Bérberis) - were most effective.

The increase in summer temperatures is intensifying and causing the rise of air pollution by photochemical transformation. The main source of pollution in cities are vehicles. Calculations of a convective jet from the warm surface of intersections and overpasses have been performed and the secondary formaldehyde contamination by photochemical transformations was estimated. It was shown that the non-carcinogenic risk is significantly increased with the concentration. At temperatures above 30°C, the non-carcinogenic risk is more than 10 (significant) and requires in-depth studies of the harmful influences. Carcinogenic risk ranges from the median to acceptable and requires dynamic control and in-depth studies. Reducing the risk is possible by "green" design: "green" roofs, vertical greening, facade blocks, etc. Using phytoncide plants destroys the pathogenic microflora and improves the microclimate of the premises. Proposed is an assortment of plants suitable for medical and educational buildings within a continental climate area.

Wzrost temperatur w lecie nasila się i powoduje wzrost zanieczyszczenia powietrza poprzez transformację fotochemiczną. Głównym źródłem zanieczyszczenia w miastach są pojazdy. Wykonano obliczenia strumienia konwekcyjnego z ciepłej powierzchni skrzyżowań i wiaduktów oraz oszacowano wtórne zanieczyszczenie formaldehydem przez transformacje fotochemiczne. W temperaturach powyżej 30°C ryzyko nierakotwórcze wynosi więcej niż 10 (znaczące) i wymaga dogłębnych badań dotyczących szkodliwości. Ryzyko rakotwórczości waha się od mediany do akceptowalnej i wymaga systematycznej kontroli i dogłębnych badań. Zmniejszenie ryzyka jest możliwe dzięki „zielonemu” projektowi: „zielone” dachy, pionowe zazielenienie, bloki elewacyjne itp. Zastosowanie roślin fitonitowych niszczy patogenną mikroflorę i poprawia mikroklimat przedwczesnych zmian. W artykule zaproponowano gatunki roślin odpowiednich do budynków medycznych i edukacyjnych w strefie klimatu kontynentalnego.
