AbstractThe quality and potability of waters of the Tyśmienica River Basin were determined in 2017 at eight measuring stations. The paper presents analyses of the physical and chemical parameters of surface waters of the basin. With regard to suspended solids, pH value, electric conductivity, sulphates, ammonia, chlorides and phosphate, the water was classified as having a very good ecological status. In the case of Kjeldahl nitrogen, the waters were classified as having a good ecological status. In the case of the remaining parameters, i.e. BOD, DO, TOC and COD, the status varied among stations. The values of all the physical and chemical parameters complied with the values for undisturbed conditions. Only ammonia and COD showed significant differences among stations. The WPI values for each measuring point ranged from 0.90 to 1.56, what corresponds to the descriptive indicators of moderately polluted water. The high concentrations of COD and TOC indicate that high-performance treatment processes (category A3) must be used to ensure that the water is suitable for drinking.

Domestic Purpose

In this project, Polluted water sample from a Pond is collected for treating it by using Natural Coagulants. The pond is located in Madarpakkam Village, near Gummudipoondi, Tamilnadu, India. There were 4 water samples collected from four different points around the pond at depth of 0.5m, 1m, 1.5m and 2m. The water samples were analyzed for physical and chemical parameters with reference to the code IS 10500-1991. The objective of this project is to reduce the level of turbidity and bacteriological contaminants from water using locally available Natural Coagulants and to reduce the concentration of particular matter such as suspended particles, parasites, bacteria, algae, virus and fungi and to make use of the treated water for domestic purpose, as it reduces cost about 30% to 70%, the usage of these Natural coagulants will be more in future. It is nontoxic and non-corrosive. So, it is safe for human health. The usage of Natural coagulants can be increased in future as it increases the Water quality.

Abstract The aim of the study was to determine actions towards enrichment of natural aspects of the water reservoir in Zaklików, with consideration of nature protection and social needs. For this purpose, physical and chemical parameters of the reservoir, floristic and physiognomic characteristics of the area, cartographic analysis of land use, natural and touristic valorisation, and the concept of tourism development of the area were considered. The reservoir, based on the ESMI index, rated as moderate ecological status. The highest natural and tourist values, as well as the highest intensity of conflict between them, were located in the north-eastern and central part of the study area. Based on all analyzes, a concept of development of the study area was created, consistent with the local development plan.

The genus Dragonhead (Dracocephalum L.) includes 72 species of essential oil-bearing plants belonging to the Lamiaceae family. Many of them have long been used in a folk medicine of different countries. Moldavian dragonhead (D. moldavica L.) has been identified as the most promising species for the complex phytochemical research since it was successfully introduced in the climatic conditions of the Ukrainian forest-steppe zone and due to the presence of its various botanical forms and varieties. The aim of this study was the phytochemical analysis of the main groups of secondary metabolites in the herb of violet-flowered form of Moldavian dragonhead  (D. moldavica L.) under its cultivation in Ternopil region (Ukraine). The herb of the plant was harvested in July of 2018‒2019 years during the flowering period. The essential oil was obtained from the plant raw material by the hydrodistillation. Such physical and chemical parameters of the essential oil as a relative density, refractive index, optical rotation, acid number and solubility in ethanol were studied. The method of thin layer chromatography (TLC) was used to determine the specific sequence of bands in the chromatograms of essential oil. The method of high-performance thin-layer chromatography (HPTLC) was used for the identification of phenolic compounds in the herb. The component composition of polyphenols was determined by the high performance liquid chromatography (HPLC). The specific physical and chemical parameters as well as the «chromatographic profile» of essential oil have been established. The main compounds of the polyphenolic nature were revealed by the chromatographic methods. In particular, rosmarinic and caffeic hydroxycinnamic acids were identified in the methanol extract of herb by the HPTLC method. The HPLC analysis of phenolic compounds in the 70% ethanol extract of raw material established that rosmarinic acid was its main polyphenol. It was found the decreasing of polyphenol contents in the D. moldavica herb in such direction: rosmarinic acid (3.01%) > apigenin-7-О-glucoside (0.67%) > apigenin (0.29%) > caffeic acid (0.28%) > luteolin-7-О-glucoside (0.13%)> hyperoside (0.12%) > ferulic acid (0.09%) > chlorogenic acid (0.08%). The obtained data could be used for planning pharmacological studies of the phytosubstances developed from the Moldavian dragonhead herb.

The present study was conducted in Salt marshes and Salt pans in central parts of Iran. 121 specimens of ants were collected by trapping and hand during spring, summer and autumn 2017 to 2019. Nine species belong to two subfamilies of Myrmicinae and Formicinae were identified. The vegetation, physical and chemical parameters of soil such as salinity, Ph, and other factors were investigated. Darband Shoor Mountain station with five species had the highest diversity and vegetation density and the lowest salinity of soil (72.14 ds/m) whereas Salt Lake station had only one species, with no vegetation and the highest salinity of soil (153.15 ds/m). Cataglyphis lividus (André, 1881) was the dominant species in all the stations except in Darband Shoor Mountain station. All the species were reported for the first time from salt marshes and salt pans in the central parts of Iran and were approved by Prof. Brian Taylor, in Royal Entomological Society of London, England.
