The aim of our research is to study the degradation of neonicotinoids in the environment. As a part of the research we will investigate photochemical degradation in water (reactions caused by natural sunlight, reactions using mercury lamp). As the model compound we will use imidacloprid. We will also trace the degradation processes of imidacloprid in soil and in vegetables under natural conditions. Beside this we will try to determine the degradation products and metabolites and try to establish, how they incorporate in the environment. On this basis we will try to propose the mechanism of degradation. For the isolation and detection we will use classical analytical methods, such as solid phase extraction and liquid-liquid or solid-liquid extraction, in combination with gas and liquid chromatography with different detectors (MS, DAD).Results of the degradation of imidacloprid will be combined with toxicity tests for terrestrial isopods and with standard toxicity test with D magna. During two or four weeks of experiments with terrestrial isopods we will follow weight, assimilation efficiency and mortality. At the end of experiments some of biochemical parameters, such as acetylcholinesterase activity, glutathion-s-transferase activity, lipids, proteins and glycogen wiil be determined after the exposure to imidacloprid in food. Acute toxicity of imidacloprid will be determined with establishing of normal movement of D. Magna. In chronic test we will follow their reproduction. In this research we want to make a comparison in behaviour of organophosphates and neonicotinoids in the environment. This can be done by using already existiong methods for the determination of concentrations and on the basis of toxicity tests for carbamates and organophosphates, developed also in our laboratory. We want to find out, if the replacement of organophosphates with neonicotinoids in suitable and what kind of concequences it might have for nontarget organisms and lifeless nature and also for the mankind.
