Information subsystem of the Ca/Mg ratio as a database for studying its influence on human health.

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.

Information subsystem of total hardness (Ca + Mg) as a database for studying its influence on human health.

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.

[The Split sulphur spa].

This paper presents the chemical composition of the main sulphur springs in Croatia and compares it with the sulphur content in the water from the Split spa. It also presents the results of monitoring the content of chlorides and hydrogen sulphide as well as the sulphur water temperature during 1987, 1988 and 1996 with the objective of studying the hydrological characteristics of this water and its origin. Since the sulphur water content during the dry periods significantly differs from the sulphur water content during rainy winter periods, this paper also compares the results obtained for the mentioned two periods. According to the monitoring results it can be concluded that sulphur water consists of seawater, and hydrocarbonate surface water with a fairly constant water content during dry periods, while the hydrocarbonate water content increases during rainy periods.

[Sodium levels in the Dalmatian water resources in 2003].

The objective of this paper was to analyse the sodium levels in the spring water, surface and groundwater in Dalmatia during 2003. The sodium concentrations were computed from the difference between coefficient K1 (the ratio between the chlorides and sulfates sum and the carbonate hardness) and K2 (the ratio between non-carbonate and carbonate hardness) and carbonate hardness. The average sodium concentrations have been expressed by a median and they ranged from 1.8 mg/L Na to 17.6 mg/L Na in the spring water, in the surface water they ranged from 1.0 to 502 mg/L Na and in the groundwater they ranged from 11.1 mg/L Na to 124.3 mg/L Na. In the spring water the sodium concentrations varied from 32% to 217%, in the surface water from 40% to 159% and in the groundwater from 77.3% to 180%. According to the corrosiveness coefficient K1, 83% of the spring waters are classified as non-corrosive and 17% as water with a low degree of corrosiveness; 84% of the surface waters are classified as non-corrosive water and 16% as very corrosive; all groundwater is classified as very corrosive water. Out of the total of 60 analyzed water resources 64% are classified as hypotensive, 20% as normotensive and 17% as hypertensive water. The drinking water has been defined as hypotensive (<10 mg/L Na), normotensive (from 11 to 20 mg/L Na) and hypertensive (>20 mg/L Na) by relating the sodium concentration projectively with the notion of arterial pressure knowing that an increased sodium concentration in blood increases the blood pressure. From the informatics standpoint the data related to health should be classified into data bases which can serve as a methodological starting point for studying the influence of sodium upon human health. Consequently, epidemiological studies should relate various sodium levels in drinking water to other factors which affect human health.
