Abstract

Forensic science is the emerging field of science to solve the different crimes in easy way. Over the past sphere of rhetorical science has practiced an interesting development and a considerably increased public profile. The prominence of forensic science has resulted from scientific and technological advances, raised reliance of enforcement agencies and judicial systems economic science, social science, dentistry, pathology, toxicology, entomology, psychology, accounting, engineering, and cyber and its popularisation through the mass media. The term forensics has been hooked up to several totally different fields: forensics. Forensic proof is gathered, examined, evaluated, understood and conferred to create sense of a happening and supply investigative leads. Thanks to increasing the various techniques to try and do the crime, there should be some distinctive and

numerous strategies to research it. Some of the crimes are well occurred, that in investigation there are not any clues and evidence would be found to more investigation. So, the forensic chemistry will facilitate to notice and sense the proof on the crime scene. Forensic chemistry may be an important and broad field of rhetorical science. In this review it explains, how and therefore the temporary introduction of forensic science and forensic chemistry. It represented the scope of the forensic the forensic chemistry is helpful filed of the forensic science. It additionally explains the various fields of the forensic science chemistry including forensic toxicology for the higher and technological future. It also describes the information on drug as

evidence and how to investigate it in forensic way for the crime detection. Explosion on various places are the destruction to the political department. Therefore from this ways that, the terrorist activities are increasing to destroy the country in crime scene. economical method. So this review article also explains the analysis and principles of the forensic chemistry for the explosion
