For the development of Slovenia the achieved results represent particularly the possibility for ensuring of a cleaner environment and control over the pollution with toxic substances. The development of new analytical and biomonitoring methods for assessment of environmental pollution and related processes (i.e. algal blooms) is important in this regard. Such achievement are the new methods of TLS detection in combination with separation techniques such as HPLC and ion chromatography, or biosensors and application of indicator organisms, as well as the LIDAR system for remote sensing of environmental pollution, which enables determination of aerosols, their sources and transport in the atmosphere. Laser induced degradation of organophosphates is a promising and environment-friendly method for decomposition of OP compounds and other pollutants in aqueous media, since it does not require additional reagents, which are potential pollutants. The application of microorganisms for degradation of OPs on the other hand offers new possibilities for bioremediation. Equally or even more important is the applicability of new methods for food quality control and detection of adulteration in some representative products such as olive and other vegetable oils, and fruit juices, with which we can successfully compete on the international market. Similarly, local cultivars of sweet cherries can be promoted over the foreign ones, based on their higher content of anthocyanins. From this prospective the following achievements are noteworthy: - Development of an IC-TLS method for simultaneous determination of Cr(III) and Cr(VI) species and its application for analysis of drinking water - Determination of OP and carbamate pesticides in contaminated vegetables and validation of the optothermal AChE biosensor by GC-MS - Development of HPLC-TLS technique for determination of beta carotene and other carrotenoids in vegetable oils and quality assessment - Determination of the effects of environmental factors and chemicals on the content of anthocyanins in sweet cherries - Two dimensional LIDAR measurements of aerosols and formation of a database for aerosol transport modeling
