Forensic Toxicology Forensic toxicology plays an exceptionally vital role in linking victim deaths to drug use‚ poisonings‚ and the detection of foreign chemicals and toxins in the human body. The utilization of analytical chemistry and a few chemical tests can tell investigators if the victim was under the influence of any drugs or even poisoned‚ by studying samples of blood‚ urine‚ hair and even bodily fluids. Forensic toxicologists detect and identify the foreign chemicals in the body‚ the

Early History of Toxicology Toxicology can be defined as the branch of science that deals with poisons‚ and a poison can be defined as any substance that causes a harmful effect when administrated‚ either by accident or design‚ to a living organism. By convention‚ toxicology also includes the study of harmful effects caused by physical phenomena‚ such as radiation of various kinds and noise. The history of Toxicology dates back to the early humans who used animal and plant poisons for hunting and

safe manner. Toxicologists‚ the scientists who help determine the limits for safe use of materials‚ use modern technological research methods‚ including tests on animals‚ to protect human and animal health and the environment. What is toxicology? Toxicology is the study of how chemical substances interact with living systems and affect normal processes‚ and the use of this information to predict safe exposure levels. Toxicological research and testing helps us to live safely and to derive benefit

1. Introduction Toxicology is defined as "the study of the adverse effects of chemical‚ physical or biological agents on living organisms and the ecosystem" and is based on the 16th century principle that any substance can be toxic if consumed in sufficient quantity. In a general sense‚ the toxicity of a substance could be defined as the capacity to cause injury to a living organism. [1] A highly toxic substance will damage an organism if administered in very small amounts; a substance of low toxicity
