CHROMIUM RESEARCH

DRAFT

Potential Level of Exposure to Jersey City Residents due to Inhalation of Chromium VI - between 1985 and 2006 - by Census Block Groups

This map is a draft that will ultimately be used in the study of lung cancer in Jersey City in relationship to historical chromium waste exposure. This version represents a work in progress. We are investigating ways to make the map more accessible and easier to interpret. At the same time, we are actively seeking public comment from the residents of Jersey City about areas that may have had a high potentially for chromium exposure to residents in the past.

Does the map accurately represent these areas? Are there areas that, in the past, may have had a high potential for chromium exposure that are not represented on the map? Keep in mind that we are specifically interested in historical exposures. Therefore, the chromium waste sites that are important for this investigation may have been excavated or capped. Even if the site is no longer contaminated it may be important because of the exposure caused in the past. Also keep in mind that areas of new housing near waste sites may not be appropriate for consideration because of the relatively long period between exposure to chromium and the diagnosis of cancer.

Once we receive public comment and input, we will finalize the map. Once that occurs, the New Jersey Department of Health and Senior Services will combine the information represented by the map with New Jersey State Cancer Registry information specific to Jersey City to investigate whether historic rates of lung cancer are associated with residence near a chromium waste site at the time the cancer was diagnosed.
