INTRODUCTION TO FORENSICS - APPLICATION OF NATURAL SCIENCES

Abstract

A well-known forensic material used in forensic technique is carbon monoxide on environment. In literature an important element that makes it difficult to assess the circumstances of fatal poisoning is the individual way of reacting the body to the action of carbon monoxide. Often staying in the same conditions cause that some people are poisoned while others alive. ''Introduction to forensics - application of natural sciences '' is a scientific presentation in order to disseminate preventive methods. The policy on environment is undoubtedly a theme to these important research methods. In order to analyze in the written work that toxic gas in strictly defined cases are the base of evidence. Empirical studies on the example of environmental protection included: quantitative analysis based on the Legalis Legal Information System, directions, noticeable tendencies in described scope, results of empirical research. Toxic gases on environment are used in the evaluation of the material for palynological analyze. The study took into account the analysis of the most suitable places on the body or clothing for taking palynological samples. The analysis covered whether the forensic traces of carbon dioxide recorded on the surface of the body or clothing, reflect the composition of vegetation occurring in the area of research and whether they can be used to mark the time of the event. The obtained results indicate that traces of carbon dioxide may be useful in determining the time of the event in practice in forensic science.
