Swiss scientist Paul Müller was awarded the 1948 Nobel Prize in Physiology and discovered the properties of DDT. However, is toxic to many animals, including humans, unfortunately it is insoluble in water, and fat soluble. It moves very easily through the environment, in such way that regions that have not yet been sprayed with DDT have shown a clear site of it such as the bottom of the ocean. DDT also breaks down very slowly in the environment and it concentrates in body tissue. The publishing of Rachel Carson's Silent Spring in the 1960s, argues that DDT and pesticides caused cancer and also there has been concern regarding the effects of chemical pesticides on the environment. In the environment, the biological concentration of chemical pesticides tends to increase the higher the animal is in the food chain.
