Ethylene dibromide
EPA Designation Regulated
EPA Classification Organic Chemicals
EPA Levels 1,2 zero MCLG (mg/L)
5e-005 MCLG (mg/L)
Alternative Names EDB
Sources Discharge from petroleum refineries
Ethylene dibromide is a a pollutant from petroleum refineries that was formerly used as gasoline additive and a pesticide suspended from use by EPA in 1984.

Overview

Ethylene bromide, also known as EDB, and 1,2-Dibromoethane, is a colorless, heavy synthetic organic liquid with a mildly sweet chloroform-like odor.

Uses

Ethylene dibromide is mainly used in an anti-knock gasolene mixtures, particularly aviation fuel.

Health Effects

Some people who drink water containing ethylene dibromide well in excess of the maximum contaminant level (MCL) for many years could experience problems with liver, stomach, reproductive system, or kidneys, and may have an increased risk of cancer.

EPA Definitions:

1Maximum Contaminant Level Goal (MCLG) - The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety and are non-enforceable public health goals.

Maximum Contaminant Level (MCL) - The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to MCLGs as feasible using the best available treatment technology and taking cost into consideration. MCLs are enforceable standards.

Maximum Residual Disinfectant Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

(TT) Treatment Technique - A required process intended to reduce the level of a contaminant in drinking water.

Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

2 Units are in milligrams per liter (mg/L) unless otherwise noted. Milligrams per liter are equivalent to parts per million.
