These levels-are very low and do not indicate that the combustion processes occurring at the World Trade Center site are causing hazardous concentrations of dioxins and PCBs in the outdoor the air at North End Avenue. The total TEQ is below the California chronic reference exposure level of 3.5 pg/m3, which is the only standard that we have encountered to date and is based on long term exposure. Additionally, the EPA estimates that an average daily exposure to TEQ is 119 pg/day. The major source of dioxin exposure is diet, due to its tendency to bioaccumulate up the food chain. In other words, . a TEQ of 2 pg/day is thought to be from inhalation exposure and the other 117 pg/day is thought to be from meat, dairy and fish intake.
The preliminary results of the Polyaromatic hydrocarbons indicate that the levels of these individual compounds are below their respective standards and guidelines.
Please know that we are processing the data as diligently as possible and will offer a full report in the near future.
Should you have any questions, please call me at the above number.
