Abstract:
Nanotechnology is defined as the design, synthesis and application of nano-scale materials. Particles of 1-100 nm are considered nanoparticles. The presence of nanoparticles and nanotechnology is increasing in almost all branches of industry (medicine, pharmaceutical industry, color industry, cosmetics and others). The increasing presence of nanoparticles in everyday use implies increasing presence of nanoparticles in the environment. The influence of nanoparticle on the environment and its components is the research area of nanotoxicology. Biochemical markers are quantitatively measurable changes in biological systems in response to exposure to xenobiotics. Early biomarker response to xenobiotic exposure is used as a tool for predicting possible exposure impacts. This work investigated the effect of ZnO nanoparticles on the expression of biomarkers (AChE, CAT, GST, MT, TBARS) in earthworm Eisenia fetida. Biomarkers in earthworms represent a useful tool for soil monitoring and environmental risk assessment, and in recent years they have become more significant in assessing the impact of pollutants on soil organisms. For these reasons, Eisenia fetida was used as an experimental organism.
Upravo iz tih razloga kao eksperimentalni organizam korištena je Eisenia fetida.
