U dana\u0161nje vrijeme geokemijska se istra\u017eivanja sve vi\u0161e ve\u017eu za pra\u0107enje stanja i o\u010duvanje okoli\u0161a. U tu svrhu, prostorni se geokemijski podaci u geoinformacijskim sustavima (GIS) povezuju u baze podataka, iz \u010dega nastaju geokemijske karte i atlasi koji su potreba, a sve vi\u0161e i standard nacionalnih programa odr\u017eivog razvoja.<\/p>\n

U Zavodu za geologiju su geokemijska istra\u017eivanja usmjerena na I) izradu geokemijskih atlasa drena\u017enih bazena<\/a><\/em> u kojima se izdvajaju geogeni i antropogeni utjecaji na tlo i procjenjuje njegovo eventualno one\u010di\u0161\u0107enje; II) urbano geokemijsko ispitivanje tala u naseljima i gradovima Republike Hrvatske<\/a><\/em> vezano za geokemijsku karakterizaciju tala u smislu detekcije povi\u0161enih sadr\u017eaja potencijalno toksi\u010dnih kemijskih elemenata \u0161to ima izniman zna\u010daj za dugoro\u010dno planiranje urbanizacije naselja i gradova, a bitno se odra\u017eava i na samu kvalitetu \u017eivota u njima.<\/p>\n

U Zavodu za mineralne sirovine i marinsku geologiju provode se geokemijska istra\u017eivanja, koja uklju\u010duju geokemijsko kartiranje i rekonstrukcije kvartarnih okoli\u0161a na temelju jezerskih i morskih sedimenata te geolo\u0161ko istra\u017eivanje podmorja. Geokemijsko kartiranje RH rezultiralo je izradom geokemijskog atlasa RH (Halami\u0107 & Miko, 2009) i omogu\u0107uje dugotrajniji monitoring geokemijskog stanja tala, te \u00a0pra\u0107enje organske tvari u tlima. Istra\u017eivanje geokemije okoli\u0161a uklju\u010duje i geokemiju urbanih podru\u010dja, u svrhu utvr\u0111ivanja antropogenog utjecaja na okoli\u0161. Geokemijska karakterizacija jezerskih i plitkomorskih sedimenata i njihovih slivnih podru\u010dja provodi se za rekonstrukciju kvartarnih okoli\u0161a, utvr\u0111ivanja porijekla materijala, stupnja one\u010di\u0161\u0107enja i zakiseljenosti odnosno eutrofikacije jezera, rijeka i mora, kao i \u0161umskih tala, uzrkovanih klimatskim ili antropogenim promjenama.<\/p>\n

Geokemijska istra\u017eivanja okoli\u0161a provedena su u sklopu projekta \u201ePromjena zaliha ugljika u tlu i izra\u010dun trendova ukupnog du\u0161ika i organskog ugljika u tlu te odnosa C:N\u201c<\/strong><\/a><\/em>, tijekom kojeg se provelo uzorkovanje tala Hrvatske sa 720 lokacija i analiziralo ukupno 1880 uzoraka.\u00a0 Rezultati projekta su izra\u010duni organskog ugljika (Corg) u tlu, rekalkulacija zaliha ugljika (C) u tlu napravljenih 2012. godine s novim podacima za C i fizikalnim parametrima, izra\u010duni Corg u organskom sloju za \u0161umska tla, izra\u010duni ukupnog du\u0161ika (N) i odnosa C i N, definiranje i smanjenje naj\u010de\u0161\u0107ih izvora nesigurnosti pri procjeni zaliha Corg u tlu (gusto\u0107e tla i kamenitosti ili skeleta u tlu) te izrada i valorizacija regionalnih pedotransfernih funkcija radi bolje procjene gusto\u0107e tla i skeleta iz ostalih dostupnih podataka. Rezultati projekta dostupni su na ENVI portalu okoli\u0161a:<\/p>\n
