the systemic circulation. The drug may still be subject to repeat extraction and metabolism by the liver even after it reaches the systemic circulation. This anatomic location within the circulatory system makes the liver prone to chemical-induced toxicity. Once transported to the liver‚ enzymes break down parent drug into less biologically active forms that are less toxic to the body in a process known as biotransformation. This process also makes drugs more suitable for excretion by the kidneys

(Visser) The use of Corexit was an extremely controversial one. A study from Georgia Tech and Universidad Autonoma de Aguascalientes in Environmental Pollution journal stated that Corexit increased the toxicity of the oil by 52 times.

When it relates to cosmetics‚ the most common procedure is acute toxicity tests. The subject‚ generally a rabbit‚ is exposed with substances in deodorants and hairspray by spraying the product directly around the animal while confined in a tight space. This procedure determines the lethal toxicity of the substance. In most cases‚ the rabbits are placed in full-body restraints. The end result generally ends with the demise of approximately

Drug discovery is a process in medicine and pharmacology where a drug is discovered and designed. In the past drug discovery was very different to the current form‚ previously active ingredients were used to tackle illnesses. Nowadays more detailed research on diseases has been pursued‚ details such as what the genes are coding or what protein is involved‚ therefore are allowing the designing of drugs to target specific sites to act on the disease. Once detailed information of the disease has been

With all of this research‚ the toxicity of the gases on earth would be reduced to let the citizens become safe and breathe freely.
