Lead as a Toxicant to an Organ or Organ System
Lead is basically a naturally occurring toxic metal whose increased use in the recent past has contributed to widespread environmental contamination and human exposure. The naturally occurring toxic metal contributes to huge public health problems across the globe because of increased human exposure. The effects or toxicity of lead on an organ or organ system has contributed to extensive research as part of measures to develop ways of preventing these effects and minimizing human exposure to lead. One of the researches that have been carried out in the past decade includes a study by a group of researchers on the cellular impact of lead poisoning and its medical picture. Brochin et. al. (2008) carried out the study to examine the effects of lead intoxication on the nervous system, where the toxic metal has considerable detrimental effects as compared to other organ system.
According to the findings of their study, Brochin et. al (2008) states that the toxic metal blocks the N-methyl-D-aspartate receptor in the nervous system. This receptor is an effective receptor that plays a crucial role in the maturation of brain plasticity i.e. The changes that take place in brain organization. As a result of the blockage of N-methyl-D-aspartate receptor...
Toxins are poisonous substances that can cause harm to human beings via one or more of its physiological systems. For example, DDT is a toxin used to kill insects but which also affects the human endocrine system. Tetrodotoxin is a toxin found in the venom of animals like frogs and pufferfish, but if it enters the human nervous system can cause paralysis or death. Mercury is a naturally-occurring element like
Initial concentrations may be minute, but because the body does not adequately eliminate or metabolize these compounds, they accumulate in the tissues. This occurs until the concentrations become significant enough to interfere with the bodies functions. This is problem is exacerbated by the challenges associated with the extraction of these metals from the environment, once they have entered. These metals are very difficult and expensive to remove from contaminated
high concentration of road salt on lead solubility. The paper describes the impact in the light of several academic articles and the observations from them. Total 8 academic articles have been reviewed and out of them some major findings are used as a basis for this paper. An important aspect of studying Pb (Lead) is its combination with the road salt. There have been several studies on the same topic,
Skeletal and Muscular Systems: The human body is made of several parts and systems that perform various functions to sustain an individual's life. The skeletal and muscular systems are examples of important systems in the body with various functions. The skeletal system can be described as the body framework on which the human body is built (Turley, 2011). This system is made of 206 bones in addition to ligaments and cartilage
Information System holds in Accounting Industry's future? Looking through the glass and estimating what the future holds for any individual or profession is always a difficult exercise as the trends in any business or profession may change and so the path of development. It is better to look at the experience of some companies whose systems have changed over the past few years and thus try to estimate what is
