Toxicology
Environmental Toxicology is a young (1965) and interdisciplinary science that uses both basic and applied scientific knowledge to understand natural and human caused pollutants, life cycle and their impacts upon structure and functions of biological and ecological systems. Research in Environmental Toxicology includes both laboratory experiments and field studies. The main purpose of Environmental Toxicology wants to answer two main questions 1.) How the release pollutant causes harmful effects? 2.) What can we do to prevent or minimize risk to biological and ecological system?
Environmental Toxicology’s objective is breakdown into a 5-steps understanding process useful for research/regulation:
• Release of pollutant into the environment
• Transport and fate into biota (with/out chemical transformation)
• Exposure to biological and ecological system
• Understanding responses and/or effects (molecular to ecological systems)
• Design experiments, remediation, minimization, conservation, and risk assessment plans to understand, eliminate, prevent or predict environmental and human health pollutions situations.
People misunderstand Environmental Toxicology as a scientific discipline that only focus on chemicals into the environment. Environmental toxicology covers more than only chemicals into the environment; it also includes studying and understanding the adverse effects caused by those chemicals' release into the environment on living systems such as wildlife, aquatic species, pets, humans and ecological systems. Furthermore, the rich fabric of ideas, core concepts, literature body, technology and ideologies that merge together to develop Environmental Toxicology is rather a dissimilar process through most educational institutions. This may be the point in case that Environmental Toxicology is a young interdisciplinary science and controversy regarding what to include in a curriculum is an

    Overcrowding: Overcrowding in houses can arise from several causes, and the physical and psychological effects on people living in overcrowded conditions can be quite severe. Overcrowding poses serious direct and indirect health risks to all segments of the population, particularly the elderly, young children, and the disabled. Overcrowding results in insufficient ventilation in homes, causing or exacerbating respiratory illness. Susceptibility to disease, the severity of diseases, the spreading of illness, and the mortality due to disease all increase as a result of social and physical overcrowding. Overcrowding physically and emotionally overburdens mothers and other caregivers, increasing health risks of dependents. Lack of space and overcrowding directly impacts on the physical development and psychological wellbeing of disabled residents.…

    Ecosystems have a way of maintaining themselves under ordinary conditions but when a new factor is added that will most likely threaten the environment action needs to be put forth. Our environment is affected by many pollutants on a daily bases forming a threat to natural stability. For example some of the most polluted parts of the environment are bodies of water like that explained in our lab. Once pollution occurs animals can be affected in many ways even to the brink of death. In the lab the stream is getting pumped with salty potassium filled water that can kill daphnia, habitants of the stream, if the concentration gets too high. To prevent this a real-time assay can be performed. This is a short timed test that we use to measure the effect of pollutant on organism by finding the smallest concentration possible that could still be a bother. This is a valuable tool because we can get direct results from a living organism by detecting stress signals all in a short period of time allowing us o fix the problem quicker. Using an organism for the assay is the best choice because there are many variables that can be used to identify stress on the subject because of a specific input.…

    Dr. Theodora Colborn was a toxicologist who founded the quote, “endocrine disruptor.” This term means how chemicals can destroy and effect health of the endocrine system. Colburn earned her Ph.D when she was 58 from the University of Wisconsin (Grossman, Vandenberg, Thayer, & Birnbaum, 2015, pg. A54). Before going back to school, Colborn was a sheep farmer and a grandmother (Motavalli, 1997, pg. 2). Thirty-five years ago, she did research on species of the Great Lakes who had health issues. She concluded that the cause of these problems were from man-made chemicals and pesticides. Her studies have shown the scientific community how the smallest amount of chemicals can effect an entire ecosystem. When Colborn was 76 she created two groups, important…

    Poison gases also have negative impacts on the nature. Chlorine gas is very harmful to organisms living in water because chlorine dissolves very well when mixed with water (Chlorine). Chlorine is one of the most reactive chemicals and it reacts with other chemicals in water, creating more sodium chloride, which is salt. If there are more salt in water, many freshwater fish would not be able to live in water since they cannot tolerate large amount of salt. Chlorine gas is also harmful to animals and plants when they inhale the gas since it can easily escape from water and enter the atmosphere. Animals and plants don’t store chlorine but repeat exposure to the atmosphere of chlorine can affect their immune system, blood, heart, and respiratory system.…
