Information subsystem of the chemical coefficients K1 and K2 as the base for the study of the ecological factors that influence human health.

With regard to the relatively limited water supply in the area of Dalmatia (Southern Croatia), water supply system and health care institutions are especially interested in observing and monitoring the waters, as well as preserving their quality. The ecological need to sum up the work on water quality investigations led us to monitor the environment. Because it is necessary, from the informatical aspect, to organize mass ecological health data into databases, the relational database for the research of chemical analyses (coefficients K1 and K2) as the methodological foundation for the study of the ecological factors that influence human health is defined in this paper. Results used for the prototype implementation subsystem of the chemical water analysis control are based on the investigations of the Water Examination Department of the Public Health Institute of the Split-Dalmatian County (Croatia). Over 2500 data comprised the examination sample. The software used included Win'95, MO'97, and Paradox 4.5, while the hardware used included Pentium II 200 MHz, floppy, 64 MB RAM, HDD 2.1 GB, CD x 24, HP Ljet 4L.
