Rohm and Haas Says Review of Cancer Cases Shows No Apparent Link to Chemicals
PHILADELPHIA - Rohm and Haas Co. said an 18-month review of an "apparently high number" of brain tumors among its employees found no significant links among the cases that would suggest a common cause, such as chemical exposure.
Fifteen employees at the company's Spring House, PA, research campus near Philadelphia have developed brain tumors since 1973. The tumors were malignant in 12 cases, and 11 of the employees have died. The company said about 6,000 employees have worked at the research center over the last 40 years.
