Geochemical environment can influence human health causing chronic medical problems related to long-term, low-level exposures to toxic agents such are trace elements. Humans can be directly exposed ...to toxic substances by inhalation of air dust or indirectly through food chain or by consumption of local water for drinking, cooking, personal hygiene and recreational purposes. Chronic medical problems related to geochemical characteristics of the environment can also be caused by chronic deficit of chemical elements essential for humans. In this paper we will present several applications of the GIS and statistical methods for relating the geographical distribution of diseases with geochemical characteristics of the environment. In addition, we are presenting methods applied for distinguishing natural distribution of elements from anthropogenic contribution, which is important information for establishing protective measures necessary for decreasing the health risk (the paper is published in Croatian).

The elemental concentrations of nine elements (V, Cr, Mn, Fe, Ni, Cu, Zn, As and Pb) were determined in soil, grape and wine samples taken from the wine producing area of Vrbnik on the island Krk in ...the northern Adriatic) using the tube excited energy dispersive X-ray fluorescence, EDXRF method. Extensive grape cultivation in Vrbnicko polje through the years approximately doubled the Cu content in the soil from this area compared to the background level determined on Krk. Most of this total Cu is exchangeable and thus available to plants. The concentrations of all other elements are similar to those found in the Krk soil. Canonical analysis showed that the main source of heavy metals in grape was absorption from the soil. Statistically significant differences in elemental composition between red and white wine were found. All elements showed greater concentrations in red grape. In spite of the elevated Cu level in the soil, the content of this metal in wine was much lower than the allowed value.

PUBLICATION ABSTRACT
The objective of this work was to investigate the interactions between the level of concentrations of Ca, V Cr, Mn, Fe, Ni, Cu, Zn, As and Pb in potable water, soil, vegetation and school children ...hair and disease incidences of neoplasms, diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism, endocrine, nutritional and metabolic diseases, mental and behavioral disorders and diseases of the circulatory system on the population groups which are homogeneously exposed to the environmental conditions. It was found that potable water among the other investigated aspects of the physical environment has the greatest impact on the public health. The environment-disease incidence interactions have been found for all investigated diseases groups. The results reported here emphasize the importance of the observation of the mutual effects of the environmental variables on the human health for the identification of their synergetic as well as antagonistic effects.
Vegetation samples were collected at 112 locations on the Croatian island Krk in the northern Adriatic sea. The collected samples were analyzed for 12 chemical elements (Ca, Cr, Mn, Fe, Ni, Cu, Zn, ...As, Br, Rb, Sr, Pb) by EDXRF method. For all of the measured elements concentration maps for the island were produced using kriging gridding methodology. This was done in order to relate variations in chemical composition of vegetation with that of soils as well as to the soil type, local environment, prevalent use of soil, and other antropogenic influences. Concentrations maps for the chemical elements have also been used in the evaluation of chemical elements transfer from plants to grazing animals, and eventually to the inhabitants of the island. Elemental transfer from the soil to the plants was confirmed by canonical correlation analysis. Good positive correlation between elemental concentration in soil and grass samples (canonical R = 0.647) was found.

Kronični zdravstveni problemi povezani s karakteristikama geokemijskog okoliša mogu nastati i zbog trajne izloženosti deficitu za ljude esencijalnih elementa. U ovom radu ćemo na nekoliko primjera prikazati na koji se način mogu neke geografske distribucije pobola dovesti u vezu s karakteristikama geokemijskog okoliša uz primjenu GIS-a i statističkih metoda. Također ćemo prikazati kako u geokemijskom okolišu možemo razlikovati prirodnu distribuciju elemenata od antropogenog doprinosa što je važno u primjeni potrebnih mjera za smanjivanje rizika po ljudsko zdravlje.
Polazeći od već povijesnih i nepogovornih spoznaja da se: “metodološki klasifikaciju i vrednovanje šumskih ekosustava može najbolje postići, ako se oni definiraju kao pedološko-vegetacijski slijed i ...to: taksonomskom jedinicom vegetacije u smislu Braun-Blanquet-ove fitocenološke škole i pedosistematskom jedinicom tla u smislu Srednje europske pedološke škole (Gračanin
1950)” autori razmatraju stanje o tome na hrvatskom krškom području. Utvrđeno je, da su ranije izrađene klasifikacije šuma i šumskih staništa (Ekološko-gospodarski tipovi Šumarskog instituta Jastrebasko, Corine Land Cover 2000 Hrvatska Ministarstva za zaštitu okoliša i Nacionalna klasifikacija staništa Ministarstva kulture) najčešće jednoulazni deskripcijski sustavi, koji nisu mogli polučiti očekivane rezultate i nedovoljne su valjanom gospodarenju (uzgoju i iskorištavanju) šuma. Glavni kriterij naše klasifikacije šumskih ekosustava na kršu su klima i tlo iskazani u zakonitostima pedološko-vegetacijskog slijeda. Pokazalo se (Bertović 1987), da Horvatove klimatogene biljne zajednice mogu biti istoznačnice za klimatska područja, odnosno tipove klime. Prema tome pedološko rasčlanjenje Horvatovih biljnih zajednica na pedosistematske jedinice dolazimo do kombnacija taksonomskih jedinica tla i vegetacijskog pokrivača i identifikacije tipova šumskih ekosustava. Autori su iskazali (tab. 2 i 3) 66 glavnih tipova i 139 podtipova šumskih ekosustava na Hrvatskom krškom području, koje se može razvrstati u 3 (tri) klasifikacijske kategorije i to: a) klasa (područje ekosustava): Obuhvaća sve tipove ekosustava u jednom bioklimatskom području; b) tip ekosustava: Osnovna je jedinica klasifikacije i određena je bioklimatskim područjem ili podpodručjem, Horvatovom biljnom zajednicom i u njoj dominantno zastupljenim taksonoskim jedinicama (tipovima i podtipovima) tla. Iskustvo pokazuje, da se Horvatove klimazonalne zajednice rasčlanjuju na 2 do 4 tipa šumskih ekosustava; c) podtip ekosustava. Izdvaja se bioklimatom, biljnom zajednicom i u toj zajednici zastupljenih edafski kontrastnih pedohora. Tako definirani podtipovi šumskih ekosustava najprikladniji su za gospodarenje šumama i izradu detaljnih karata šumskih ekosustava. Predmetni sustav klasifikacije primjenjivan je i provjeravan u dugom razdoblju, a nalazi su iskazani u opširnom djelu o Gospodarenju šumskim tlima u Hrvatskoj (Martinović 2003). Najvažniji rezultati primjene klasifikacije postignuti su u proučavanju rasta i prirasta šumskog drveća, procesa tehnogeneze šumskih ekosustava, te utjecaja turizma i rekreacije na potrajnost šumskih ekosustava. Nadalje, naša je klasifikacija našla primjenu i u
prostornom planiranju, obnovi opožarenih šuma i u konzervaciji kopnenih ekosustava
The article presents different types and scope of soil monitoring, based on ecological relationships in Parks of Nature in Croatia, to be a firm in support sustainable management of terrestrial ...ecosystems in Croatia. Taking into account very different and contrasting ecological, processes in our terrestrial ecosystems, this studyng presents those of the most significant economie and scientific importance. More than one type of monitoring is suggested including in some cases geochemical characteristics of vegetation.
