Organic materials are commonly used in urban landscapes to improve soil quality and tree health. Literature reviews suggest that the effects of organic materials are beneficial, but these impacts have yet to be evaluated using meta-analytical approach. This work presents a literature summary of 176 articles published in Arboriculture & Urban Forestry (AUF) and evaluates 33 of these papers using a meta-analysis. Research relevant to this topic is not published solely in AUF, but the meta-analysis is limited to AUF in an attempt to specifically focus on the information provided to AUF readers. This meta-analysis provides evidence of the mostly positive impacts organic materials have on shoot growth, root growth, tree physiology, and soil physical properties. It also identifies specific gaps in AUF literature for the effects organic materials have on soil chemical, soil biological, and environmental (e.g., climate, competition) properties. Further, this metaanalysis suggests the type of organic material and the mode of application have differential effects on tree, soil, and environmental properties.

The research on the development of an innovative formula of a synthetic detergent with improved environmental properties, which meet the environmental standard of SOU OEM 08.002.12.065:2016 "Detergents and cleaning products. Environmental criteria for life cycle assessment" is carried out. The accumulated theoretical and practical experience is generalized, the general scheme of designing and development of new goods taking into account features of detergents with the improved ecological characteristics is created.

Planning Methods

One of major factors of deterioration in a microclimate of urban development in the conditions of the Rostov region, is degradation of landscapes owing to violation of water balance of the territory. In article the main reasons for violation of water balance which included natural features of the region, a consequence of anthropogenic influence, climatic changes, etc. are considered. Examples from the world practice of urban planning, which show the relevance and effectiveness of compensation for the effects of anthropogenic im-pacts and climate change using planning methods, are given. The experience of the United States, the Nether-lands, Canada and other countries that use water-saving technologies in planning is considered. The rela-tionship of urban planning and the formation of sustainable urban landscapes is shown. The integration of water-saving technologies into the urban environment can be a means of optimizing landscapes and a means of creating unique urban spaces. Reclamation of the urban landscape of low-rise buildings is a necessary step in creating a modern and comfortable urban environment in the conditions of the Rostov region. Meth-ods are proposed to compensate for negative changes in urban landscapes that can be applied at the stage of urban planning. As well as the proposed methods can be applied in the reconstruction of urban low-rise buildings. The considered methods concern not only urban landscapes, but also agricultural landscapes that surround small and medium-sized cities of the Rostov region. In article the author's concept of the organiza-tion of the low housing estate on a basis Urban- facies is submitted. Planning methods of regulation of water balance of the territory on the basis of models the ecological protective of landscapes are offered: an ecolog-ical core, an ecological corridor and an ecological barrier and also analogs from town-planning practice are considered. The reclamation of urban landscapes based on urban planning methods for regulating the water balance of the territory will allow creating unique urban spaces that are resistant to local climatic conditions and the possible consequences of climate change.

Building on the principles of toxicology, this chapter describes chemicals by structure, source, use, mechanism of action, environmental properties, and target organ. Major advances in toxic effects include more detailed understanding of the mechanisms by which toxic chemicals damage receptors at the subcellular, cellular, and organ level. The chapter describes properties of various types of inorganic and organic chemicals and their adverse health effects. It discusses asphyxiants, such as carbon monoxide and hydrogen sulfide; heavy metals, such as lead, mercury, and cadmium; organic solvents, such as benzene and trichlorethylene; pesticides, including chlorinated hydrocarbons and organophosphates; and a variety of other toxic chemicals to which people are exposed in the home, community, or workplace environment. Several cases are presented to illustrate various concepts concerning chemical hazards in occupational and environmental health.
