E-learning 5This is the first time I have attended a class in this format and wondered how effective it would be. It was very effective and therefore I would definitely introduce all my friends and family to attend classes in the same format. The instructor was very knowledgeable and provided a wealth of information about the current version, especially since the last version I used was several releases ago.

Information Technology 5I have twenty plus years of experience taking training courses. I am not easily impressed, reserved with my praise, and do not usually complete surveys. My instructor is excellent, the best I've experienced on a software subject, and I couldn't imagine him doing a better job of seamlessly walking students through a breadth of information in a remote environment. He did a fabulous job packing everything and addressing student questions. I am very impressed.
E-learning 5We just wanted to let you know that the service provided, from registration to training is a very positive experience for everyone. We intend on taking more classes in the future and referring any new hires as well as friends/family members to take courses at World Class Education

Introduction to Public Health Issues in OSH
Toxicology is the science of poisons. Friis (2006) states that toxicology is a cornerstone of environmental health, and he points out that it overlaps the disciplines of pharmacology, pathology, and even epidemiology. Liebler (2006) notes that the poisons of greatest interest to those in public health today include environmental and workplace pollutants including second-hand tobacco smoke. Toxicology is concerned not only with identifying and classifying chemicals that act as toxins but also with understanding human and animal dose-response mechanisms for chemicals, including chemicals in drugs and food.
The study of toxins and particularly their effects on humans and animals has been going on for centuries, constantly evolving into the science it has become in recent years. Looking back into the history of occupational health, we can note that some of the observations made by Paracelsus, a sixteenth-century physician who is considered one of the very first toxicologists, concerned environmental pollutants as a possible cause of several forms of cancer. Today, through extensive research, it has been proven that some natural and manmade poisons can indeed cause undesirable effects such as cancer in living organisms. Liebler (2006) believes that the field of toxicology has had two major goals over the last half-century: assessing the effects of environmental pollutants on health and determining the levels at which drugs and other chemicals
become toxic to humans and animals, or to put it another way, ensuring drug and chemical safety. The goal of chemical safety is, of course, important in the prevention of workplace illness, disease, and death.
