Animal Testing Alison A. Risko Middle Township High School Imagine a world where humans are taken to laboratories and tested on in a callous manner. A world where people are injected with harsh drugs and chemicals that physically and mentally harm their bodies and their life. If this scenario does not sound acceptable to act upon humans‚ then it surely cannot be right for animals. Right now in the world thousands of animals are experiencing this

severe damage to the digestive tract. The human toxicity of 1-bromohexane includes; irritation to eyes and skin if contact occurs‚ irritation to lungs and respiratory system if inhaled‚ and skin inflammation along with itching or blistering. Some of the toxic effects that KPF6 has on humans are destruction of tissues in the membrane of the upper respiratory tract if inhaled‚ and burns on skin and eyes if contact occurs. Lastly‚ the human toxicity of dichloromethane includes; irritation of

hybrid cars. What would happen in the next few years if these batteries end up in landfills? According to environmental researchers‚ 90% of 1 million metric tons of lead which is produced every year is used for vehicle batteries (“Hybrid Battery Toxicity”‚ 2006). These batteries still have issues even though they are more environmentally friendly than the standard batteries. Nickel may cause cancer in human body because it is considered as a human carcinogen (Olberding‚ 2010). Therefore‚ many people

myristicin‚ to permit exploration of its potential to be both a carcinogen and an anticarcinogen. Limited in vivo and in vitro studies suggest myristicin could inhibit tumor formation; in this regard its ability to prevent carbon tetrachloride liver toxicity in mice is interesting. On the other hand‚ the probability that myristicin will be a liver carcinogen in experimental animals is extremely high. Myristicin is closely related to safrole‚ a liver carcinogen in mice and rats. Myristicin not only induces

Bleeding‚ ulceration‚ swollen eyelids‚ and liver problems. These are all just some of the effects of this cruel kind of testing. Toxicity tests or as they are called poisoning tests are an example of studies performed on the animals. This is where the animals are fed a substance or through a tube in their throat to see what amount they candle handle until their toxicity level go up or until dead. Other cruel tests like skin iribility tests are done where the animal is restrained to prevent them from

The scientific research that describes the impact of pesticides indicates that pesticides affect reproduction‚ growth‚ neurological development‚ and the function of the immune and endocrine systems. The wildlife toxicity data has shown that the young tend to exhibit greater sensitivity to pesticides. Other studies show that the effects of pesticides can be transmitted from one generation to the next. Exposure to pesticides can result in acute or chronic effects on
