Projects Appearance and interaction of biologically important organic molecules and micronutrient metals in marine ecosystem under environmental stress (AMBI... The main aim of the project is to investigate quality and quantity of the seawater organic matter (lipids, acidic polysaccharides and polymeric organic matter containing N catalytic atoms) that is produced in the altering environment. Ecosystem changes that will be followed imply opposite nutritional regimes, oligotrophy and eutrophy, and temperature variations. Further on, this project aims to clarify how variations in the concentrations and forms of these organic substances are reflected in the availability and cycling of micronutrients metals of interest, being Fe, Co, Cu, Zn and Cd.more » Assessment of hazardous chemical contamination in the Sava River basin NATO Science for Piece Project (SARIB) Calibrations of paleoenvironmental records in (sub)recent tufa The aim of the study was to compare for the first time environmental records (stable isotope ratios, metal concentrations and radionuclide activities) obtained from the recent tufa with those from ambient water where tufa precipitated for the first time.more » Complex investigation of organic aerosols in rural, urban and marine environment Development and evaluation of innovative tools to estimate the ecotoxicological impact of low dose pesticide application in agriculture on soil func... The ECOFUN-MICROBIODIV project aimed at developing and evaluating innovative tools to estimate the ecotoxicological impact of low dose pesticides used in agriculture on soil functional microbial biodiversity. It proposed to estimate the impact of sulfonylurea herbicide on soil microbial biodiversity and functioning. This project is based on an interdisciplinary approach conducted at different scale, from the field plot to the greenhouse, to test in corn crop the impact of chemical weeding compared to mechanical.more » Ecotoxicological significance of ABC transport proteins in aquatic organisms Project supported by the Croatian Ministry of Science Education and Sportsmore » EDA-EMERGE - Innovative biodiagnosis meets chemical structure elucidation – Novel tools in effect directed analysis to support the identification...

Uglavnom se za određivanje antioksidativne aktivnosti koriste spektrofotometrijske metode koje, iako su relativno brze i jednostavne za provedbu, imaju čitav niz nedostataka, npr. zahtijevaju korištenje skupih reagensa, nedovoljno su osjetljive i ne-selektivne, itd. Posljednjih godina postoji sve veći interes za primjenu različitih elektrokemijskih (prije svega voltametrijskih) tehnika za karakterizaciju bioaktivnih supstanci u prirodnim uzorcima. Moderne voltametrijske tehnike ne zahtijevaju upotrebu dodatnih reagensa za određivanje antioksidativne aktivnosti, omogućavaju analizu velikog broja uzoraka u kratkom vremenu, te koriste osjetljive, jeftine i lako primjenjive instrumente. Stoga je jedan od ciljeva ovog projekta razviti i validirati jednostavnu, brzu, pouzdanu, osjetljivu i preciznu elektrokemijsku metodu za određivanje ukupnog antioksidativnog kapaciteta namirnica, koja bi bila pogodna za rutinske analize hrane kako u istraživačkim laboratorijima tako i u industriji.više » Praćenja stanja okoliša na ribogojilištu RibarstvoF, Cres Praćenje kvalitete sedimenta ispod ribogojilištaviše »
