Summary:

Laino's (2009) article "Pesticides May Raise Alzheimer's Risk" states the new study on the risk of pesticides shows the possibility of Alzheimer's disease. The study showed that exposure to pesticides for a long time increases the likelihood of Alzheimer's disease. Scientists say there is an evidence to support the results. Dr. Kathleen Said did not discover the cause of Alzheimer's disease, which may be caused by genetic and environmental factors. According to the Alzheimer's Association, there is an increase of half a million patients each year by 2010 and a million patients each year by 2050. A study has been done to measure cognitive function on the 75 elderly people for seven years. Researchers found 53% of people who worked with pesticides had developed Alzheimer's disease.

Reaction:

I agree with article’s information. Many pesticides are used over all the world, which are dangerous. The World Health Organization has a scale to measure the toxicity of pesticides, which is (I high toxic – II moderately toxic – III low toxic). There is not enough information about the risk of pesticides. To know the risk of pesticides, scientists should do tests for many years. Most pesticides affect the nervous system. People who work with pesticides a receive small quantity of pesticides every day. This small quantity of pesticides accumulates in the human body, and causes diseases after years. For example, colon cancer is caused by contaminated food. As the first suspect, pesticides cause contaminated food. In my country, there is Alzheimer's disease, but we do not know what causes it.
