According to New York State Department of Health ( 2012 ) , all people are not equally sensitive to chemicals , and are not affected by them in the same way . There are many reasons for this , as follows : People ‘s bodies vary in their ability to absorb and break down or eliminate certain chemicals due to genetic differences . People may become allergic to a chemical after being exposed . Then they may react to very low levels of the chemical and have different or more serious health effects than nonallergic people exposed to the same amount . People who are allergic to bee venom , for example , have a more serious reaction to a bee sting than people who are not . Factors such as age , illness , diet , alcohol use , pregnancy and medical or nonmedical drug use can also affect a person ‘s sensitivity to a chemical . Young children are often more sensitive to chemicals for a number of reasons . Their bodies are still developing and they can not get rid of some chemicals as well as adults . Also , children absorb greater amounts of some chemicals ( such as lead ) into their blood than adults .
