An individual’s environment plays a pivotal role in their overall health. The environment can affect a range of physical and mental processes, and is considered a defining factor of well-being. As a result, specific geographic areas are instrumental in shaping an individual’s health profile. This is clearly seen in the disparity between those living in areas exposed to toxic substances, versus individuals living in clean environments. Individuals in unpolluted environments experience the advantage of a body system free from the barrage of chemical assault. Unfortunately, people who live near toxic wastes or byproducts of industry, have a body that is in constant defense of attack. This natural defense mechanism can prove
Exocrine glands, the liver and the kidneys remove toxins. A toxin is a biological poison. Some toxins are known to be stored in fat cells so it could be true that the more fat we have in our body the more toxic our body may become.

The purpose of this course is to provide the fundamental knowledge of the effects of environmental chemicals on living systems, and the toxic responses of the human and plant systems. Students will discuss risk, ethics, and social responsibility with regard to environmental toxicology.
According to research, once the chemicals are released into the air, water, or the soil, it can cause a decline in health, which can possibly result in death. About three quarters of the chemicals that comes out
These substances not only trigger liver, heart, kidney and nervous system deterioration, but also cause lung impairment and cancer.
When talking about the term Toxin, they are the substances having poisons and causing effects on the
Following the industrial revolution, societies across the world began to notice strange effects on individuals throughout certain local communities. Though toxicology was a relatively new and rudimentary practice at the time, scientists were able to trace these effects back to chemicals being exposed to industrial workers, their families, and nearby neighborhoods. Unfortunately, industry in the United States continued to expand with little regard for the effects on human health. As a result from this expansion the amount of chemicals released into the atmosphere skyrocketed continuously all the way to present day society. However, as industry expanded so did scientific technology, the understanding of chemicals, their exposure
“Chemical hazards pose an external or internal physiological threat to one or more parts of the human body. This hazard can cause both short/long term health and physical effects depending on route of entry, toxicity, amount and duration of exposure” (Haight, 2012, p. 60).
Since this is my fist toxicology course, I found it interesting to learn the variety of pathways that toxicants access to enter the human body and aquatic organisms. Even more so, the way our cells respond to the intake of such toxicants. In addition, learning the way aquatic organisms are impacted by toxicants in stream and stream sediments. Furthermore, I can use this knowledge in a career and also for my own curiosity to investigate my surroundings or spread awareness.
For the last 117 years, we have been under constant assault from environmental toxins, in our food, water, air, etc. Experts are reporting, that Environmental Toxins Are Now a Major Health Threat "We are now
Toxicology is the study of poisons and their affects on different organisms, and the different effects each toxin has on different organisms. Toxicology is a branch of biochemistry, as well as a branch of medicine, and as such one or more degrees in biochemistry, medicine, or toxicology are required for a career in toxicology. The study of toxicology is a study in which one inspects poisons in either the body or on their own, and use it for experimental purposes; one of these purposes likely being the ability to experiment with poison antidotes. There are many advancements that have helped toxicology grow into the science that it is today, and these advancements have helped make many medicines possible; the history of toxicology is important to the subject because of the progress said subject has made throughout time, from it’s beginning. As stated by Paracelsus, “All things are poisons, for there is nothing without poisonous qualities. It is only the dose which makes a thing poison” (Paracelsus), in which he explains that the dosage is what determines the poison; one of the main rules of toxicology. Toxicology is a field of science that focuses on the study and effects of different dosages of poisons on different organisms, and is also used to create antidotes for different poisons, to help those who are in need; the history of expansion has helped shape toxicology into what it is today, and is now commonly used for the good of others.
Visible ones would be through the food we consume, while the invisible ones would be air-borne and water-borne toxins.
Nelsen et al. (2014) presents and discusses what the authors believe to be the inconsistencies among the definitions of poisons, venoms, and toxins, as well as the conflation, or mixing, of these terms within the literature. The three primary classes of toxins, biological, anthropogenic, and environmental, are defined and distinguished so that the authors can further discern the biological toxins using their own classification scheme (Nelsen et al. 2014). Nelsen et al. (2014) presents the necessity of their three-class scheme, which they proposed due to the terminological inconsistencies within and among the literature on biological toxins. I think implementing a new term to detract from the misconstruction of existing toxicological definitions would be constructive, especially with the proposed corresponding binomial classification system. This review aims to discuss the breadth and functionality of the Nelsen et al. (2014) categorization of toxins.
