Task of engineering geology in land-use planning on the example of four selected geofactors

The paper deals with an evaluation of four selected geobarriers (flood lands, radon hazard, undermining and slope movements) by means of geographic information systems that are geofactors endangering or limiting landscape and environment or make certain land use impossible. The objective is to improve the possibilities of their implementation in land use planning. The research was carried out in the area numbered 4, which is one out of five realized model areas in the future. It is located in Ostrava, the third largest agglomeration in the north-west of the Czech Republic, which has been most affected by anthropogenic industrial and mining activities among the Czech cities as well as in the European scope. The area is defined by a map sheet 15-43-09 in the town districts of Mariánské Hory a Hulváky, Nová Ves, Svinov, Třebovice, Hošťálkovice, Moravská Ostrava a Přívoz, Ostrava – Jih and Vítkovice

Analysis of workability of rocks and type of prequarternary bedrock in the selected part of the Ostrava conurbation by means of geographic information systems

An up-to-date topic with which engineering geology can contribute to the requirements of practice and research, in particularthe needs of land use planning, state administration, building offices, developers, etc. is an analysis of new possibilities of providingreference information on the engineering-geological conditions by means of geographic information systems. The study in the presentedpaper deals with an evaluation of two geofactors. They are the character of rocks workability and Pre-quaternary bedrock. Workabilityis a significant limiting factor, which affects the used technology and financial demands of earth work. Especially in case of demandingconstructions, the Pre-quaternary bedrock is a geological environment which will have to be interacted with and must be taken intoaccount during selecting engineering foundation. The overall project was divided into five model areas (1-5), while this paper evaluatesa partial model area of no.1, which is defined by topographical map in drawing scale 1:10 1000 (topographic sheet No. 15-43-10).Namely they are Slezské, Moravské Ostravy, Vítkovic a Radvanice. The mentioned methodology was applied in the interest area forthe first time

Potřeby implementace geofaktorů těžitelnosti hornin a typu předkvartérního podkladu do územního plánování

The current technological means in geographic information systems bring new possibilities of implementation of important natural conditions into land-use planning. The paper focuses on two such geofactors, i.e. workability of rocks and Prequaternary base, which are very important for future foundation engineering. At the same time, the study presents the form through which it is possible to provide the information to authorized offices and developers, namely using analyses of the factors through geographic information systems. This helps to determine areas with specified conditions in terms of the geofactors in question and the relevant authorities may be able to provide the information to future developers or may take it in consideration during decision-making on future land use. The studied area (model area 2, determined by a topographic map 15-43-05 in 1:10 000 scale) is located in Ostrava, the third largest city agglomeration in the north-east of the Czech Republic (city districts of Slezská Ostrava, Moravská Ostrava, Přívoz and Petřkovice), which is however most affected of all Czech cities as well as cities in the European scale by anthropogenic industrial and mining activities.Současné technologické možnosti v geografických informačních systémem přináší nové možnosti implementace důležitých přírodních podmínek do územního plánování. Předložená studie má za cíl upozornit na dva takové geofaktory těžitelnosti a typu předkvaterního podkladu, které jsou velmi důležité pro zakládání budoucích inženýrských děl. Zároveň studie přináší formu, kterou je možno tyto informace kompetentním úřadům a uživatelům stavebníkům poskytovat pomocí analýz těchto faktorů prostřednictvím geografických informačních systémů. Vymezí se tak oblasti s vyspecifikováním konkrétních podmínek z hlediska řešených geofaktorů a příslušné úřady tak budou moci poskytnout tyto informace budoucím stavebníkům, respektive je mohou zohlednit při rozhodování o budoucím užití území v územním plánování. Studované území (modelová oblast č.2, vymezena topografickou mapou 15-43-05 v měřítku 1:10 000) se nachází v Ostravě třetí největší městské aglomeraci na severovýchodě České republiky (v městských obvodech Slezské Ostravy, Moravské Ostravy, Přívozu a Petřkovic), která je však nejvíce ovlivněna antropogenní průmyslovou a hornickou činností z velkých měst v České republice, ale také v evropském měřítku

Pesticide and Toxic Metal Pollution in Waters, Fish and Wild Animals in Vojvodina, Serbia

High concentrations of pesticides and toxic metal pollutants in the environment, often present in surface waters in nature, can accumulate in wild animals and are a significant public health concern. Serbia is a moderately developed, south European country in transition, with a long tradition in agriculture, particularly in the northern part, Vojvodina. Our study aimed to assess the presence of pesticides and to measure concentrations of toxic metals in the district of Backi Petrovac, Vojvodina. Water samples were analyzed from canals, ditches, fish from the canals and wild animals caught in the Backi Petrovac district. We identified nine pesticides in water samples. Of all detected pesticides, one was a hormonal disruptor. There were no pesticides in animals, fish and organs in a concentration above the limit of detection (LOD) in observed periods. The concentrations of toxic metals detected in superficial water (Cd, Pb, Hg, As, Mn, Cu) were below the permitted limits, as well as the concentrations of Cd, Pb, Hg, As and Mn in the whole bodies of fish. Concentrations in kidneys and livers of wild animals (rabbit and roe deer) were below the permitted limits, with the exception of cadmium, whose concentrations in some animal samples were above the permitted limit. Based on the obtained results, we concluded that in the developed agricultural region unencumbered by heavy industry, pollution by pesticides and heavy metals can be controlled
