Underground and surface waters in Dalmatia (Southern Croatia) have relatively preserved their natural characteristics since the greatest agglomeration of population and industry is located along the coast. The danger of pollution with fecal microorganism and products of biological decomposition is the most immediate problem but can be efficiently eliminated by water chlorination. The ecological need to sum up the work on water quality examination and estimation of future water quality trends resulted in water quality monitoring, i.e. in human health monitoring. It is necessary for large number of analytical and ecological health data to organize them from the informatical aspect into databases, the relational database for chemical analysis studying (the difference between anions sum and hardness) as methodological base for studying the ecological factors that influence human health defined in this paper. Results used for the prototype implementation subsystem of the chemical water analysis control are based on the investigations of Water Examination Department of the Public Health Institute of the Split-Dalmatian County (Croatia). Over 3400 data are comprised what is the sufficient examination sample. The software used included Win '95, Mo '97, and Paradox 4,5, while the hardware used included Pentium II 300 MHz, floppy, 128 MB RAM HDD 4,3 GB, CD x 24, HP DeskJet 710C.
Dalmatia is situated in the Dinaric karst in Southern Croatia. It is characterized by insufficient quantities of water during the summer months and a relatively excessive amount of rainfall during the winter and spring months. Other hydrographic characteristics of Dinaric carst include scarce and long surface streamflows with a few tributaries with changeable capacities, a small number of springs, and a relatively great number of submarine springs along the coast. The water supply and health-care institutions are especially interested in observing and monitoring water quality. A relational database has been developed for carrying out chemical analyses expressed by the Ca/Mg ratio since it is necessary to organize and integrate a large number of analytical and ecological health data. The database can serve as a methodological platform for the study of environmental factors influencing human health. The prototype database consists of data obtained by investigations which have been conducted by the water Examination Department of the Public Health Institute of the Split Dalmatian county (Croatia) University of Split Medical School. The database currently contains more than 2500 data.
Dalmatia (Southern Croatia) belongs to the Dinaric karst region. The permeability of karst soil allows a great quantity of dissolved organic and toxic matter rendering it hygienically unsafe. The hinterland of the Dinaric karst region is relatively scarcely populated since the largest agglomeration of population and industry is in the coastal zones. Hence, most of the surface flow have preserved their natural characteristics. The water supply authorities and health care institutions are especially interested in observing and monitoring water quality. A relational database has been developed for carrying out chemical analyses expressed by total hardness (Ca + Mg) since it is necessary to organize and integrate a large number of analytical and ecological health-data. The database can serve as a methodological platform for the study of environmental factors influencing human health. The prototype database consists of data obtained by investigations which have been conducted by the Water Examination Department of the Public Health Institute, Split-Dalmatian County (Croatia) and the University of Split Medical School. The database currently contains more than 3000 data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
