Here you will find basic concepts of environmental sciences that help us understand the link between the environment and human health.


In environmental health, biomonitoring is the process of taking samples of human urine, blood, tissues, and breast milk and testing them for the presence of chemicals.  In recent year the Centers for Disease Control has been including biomonitoring in the National Health and Nutrition Exam Studies.  They have been selecting an ever-increasing number of chemicals, all of which are known to be associated with human health risks which is reported annually.  In some states, like California, they have been legislatively requiring that biomonitoring studies help to inform regulatory and other policy decisions.

In 2008, a biomonitoring project was implemented by Environmental Working Group whereby they assessed the chemicals that were found in the umbilical cord blood of 10 newborns. What we learned from this study is the fact that most of the chemicals that are found in adult bodies are also circulating in our most vulnerable populations – the fetus and newborn.  The disturbing results of this study help us to understand the extent to which our bodies have been trespassed by potentially toxic chemicals.
