The Board of Supervisors Tuesday approved a $250,000 study of San Diego Bay to determine if pollutants in the water pose a health risk to humans.
Under a proposal by Board Chairman Brian Bilbray, the county's environmental health services division would conduct the study. Bilbray said San Diego Bay is among the most polluted bodies of water in the United States.
Pollutants found in the bay include heavy metals and aromatic hydrocarbons. The study is not aimed at determining the sources of the pollution, but rather to learn how the pollution is affecting people who use the bay and sea life.
The study will also determine what health risks are faced by people who use the bay for recreational purposes or consume fish taken from its waters.
Supervisors voted to ask the San Diego Unified Port District to fund the study.
