ash

The analysis of possibility of the use of ash is conducted in building of road. The chemical analysis of row of ash is executed by atomic-adsorption spectroscopy method. Entering ecological danger of heavy metals to the environment in time destruction of road is set

A list of genus Fraxinus L. (ash) species of Odessa region was made. There are was found the representa-tives of three Fraxinus L. sections: Melioides (Endl.) Pfeiff., Fraxinus (DC.) V. Vassil., Ornus (Boehm.) DC. It was made a list of most common ash species of Odessa region: F. excelsior L., F. oxycarpa Willd., F. angustifo-lia Vahl., F. americana L., F. lanceolata Borkh., F. pennsylvanica Marsh. and species of urban, private and collectible plants: F. ornus L., F. monophilla Desfr., F. mandshurica Rupr., F. velutina Torr., F. pallisiae Willmott. There was found a list of species able to interbreed: F. excelsior L., F. oxycarpa Willd, F. angustifolia Vahl. and F. americana L., F. pennsylvanica Marsh., F. lanceolata Borkh. We make a hypothesis about the existence of hybridization zone of F. excelsior L., F. oxycarpa Willd., F. angustifolia Vahl. and F. americana L., F. lanceolata Borkh., F. pennsylvanica Marsh. through the North-Western Black Sea region and likely possibility perspective of native species displacement by invasive active American species, basing on analysis of data about ash species distribution in Eastern Europe flora.

Reasons of environment pollution by waste motor oils (WMO) and aspects of environmental safety of WMO are considered. The volume of WMO generation by vehicles is calculated for Kharkiv Oblast (year 2013). Economic losses for environment pollution caused by illegal WMO utilization are calculated. Based on experimental researches, ash and sulphur contents were measured. Comparison of obtained data with M40 masut parameters has shown that WMO ash and sulphur contents are higher than the same parameters for masut. In ash from M100 masut ten heavy metals were identified; concentration of all metals (except Cu) is WMO ash was higher than their concentration in M100 masut ash. It is shown that WMO can be utilized through burning only in case of implementation of set of protective measures.
