[PDF] Principles And Practice Of Toxicology In Public Health Popular Online - video dailymotionToxicology is a scientific discipline , overlapping with biology , chemistry , pharmacology , and medicine , that involves the study of the adverse effects of chemical substances on living organisms  and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure whether it is acute or chronic , route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices. Dioscorides , a Greek physician in the court of the Roman emperor Nero , made the first attempt to classify plants according to their toxic and therapeutic effect. In , Jean Stas became the first person to successfully isolate plant poisons from human tissue.
Principles And Practice Of Toxicology In Public Health
Toxicology has been defined as the science that deals with the adverse health effects caused by chemical, physical or biological agents on living organisms. Adverse effects can range from death, cancer and disease to subtle damage to the nervous system that can result in decreased intelligence Steven, Since Paracelsus - it is known that is the dose that differentiates a poison from a remedy. We now know that other factors, such as stage gives life, age, nutrition, disease and exposure to chemicals, among other factors should also be considered. The paradigm shift in toxicology involves a transition from a science 'in vivo" to study parameters such lethal dose for half the population of animals in laboratory test conditions, for a science ' in vitro ' with studies in the key events and processes of the target molecule, cell responses and the adverse effects on human health and the environment. We work to integrate these different types of knowledge Meek et al, The toxicology program of PAHO aims to strengthen the health sector in chemical safety, through the promotion of strategies and policies that generate monitoring programs for chemical safety, with attention to information and support centers in toxicology, to address health effects from chronic and acute exposures.
The most essential goal of medicine and public health is to prevent harm primum non nocere.

Metrics details. Green Toxicology refers to the application of predictive toxicology in the sustainable development and production of new less harmful materials and chemicals, subsequently reducing waste and exposure. Being an integral part of Green Chemistry, the principles of Green Toxicology amplify the role of health-related aspects for the benefit of consumers and the environment, in addition to being economical for manufacturing companies. Due to the costly development and preparation of new materials and chemicals for market entry, it is no longer practical to ignore the safety and environmental status of new products during product development stages. However, this is only possible if toxicologists and chemists work together early on in the development of materials and chemicals to utilize safe design strategies and innovative in vitro and in silico tools.
