Doctor Cites Benzene Exposure as Likely Cause
Of High Cancer Death Rate at a Shell Refinery
By Barry Meier And Cathy Trost
Staff Reporters of Tub Wall Street Journal
WASH1NGTON-A doctOT who directed a study of an abnormally high rate of can cer deaths among workers at a Shell Oil
Co. refinery in Illinois says the cause 'most likely" was exposure to benzene produced at the facility.
But the company, quoting the doctor's own report, told the refinery workers that no scientific link had been established be tween the benzene exposure and the leuke mia cases studied.
The varying viewpoints held by the doc
tor and by Shell reflect the difference be tween informed opinion and scientific proof. But they raise questions about how companies inform their workers about industriai health hazards. The problem also is part of a broader and growing concern, in the wake of the Bhopal, India, chemical plant disaster, over the right of workers and the public to know about hazardous products and processes.
The Occupational Safety and Health Ad ministration, which sets and enforces workplace safety standards, says that
about 600,000 U.S- workers are exposed to benzene on the job. Benzene is used as an intermediate chemical in the manufacture of plastics and solvents, in addition to pet
roleum products. The controversy over the study's find
ings steins from research conducted by Dr. Philip Cole into the possible cause of a high rate of acute myelogenous leukemia at Shell's refinery in Wood River, 111. A 1983 company study reported that between 1973 and 1981. eight workers employed at the refinery died from the illness.
Statistical Averages
Based on statistical averages, only two workers should have died from the illness during that period. Dr. Cole, who told Shell the increase was "highly statistically sig nificant," was hired to review company re search and try to determine the cause of the deaths. Dr. Cole issued his report in December.
Government and industry studies indi cate that occupational exposure to benzene is a likely cause of cancer. Scientists also say that workplace exposure to certain sol vents and radiation can cause the dis ease.
"At present, I remain of the persuasion that the most likely cause of the leukemias is benzene," Dr. Cole said in an interview this week. He acknowledged that his study didn't scientifically link benzene to the high leukemia death rate, but added: "Common sense tells me it's benzene, but you can't establish scientific fact on that."
Shell maintains it has been "fully open" in presenting results of the studies to em ployees and the public. It says that while it hasn't ruled out benzene as the cause of leukemia-related deaths, it has drastically
reduced levels of the chemical in the air at its refineries in recent years.
However, a union representing the re finery workers says Shell never provided it with a full copy of Dr. Cote's report.
A comparison of Dr. Cole's reports to Shell and company statements based on it
show that: -Quoting Dr. Cole's report. Shell told
workers the study "produced no distinctly positive result, not even for benzene" as
the cause of the leukemias. The company didn't indicate, as Dr. Cole did in his re port, that the entire study may be incon clusive because, among other things, pre
cise data on worker exposure ieveis wasn't available.
-Shell said recently that its interpreta tion was that Dr. Cole's work "found there was no apparent difference in (workplace) benzene exposure levels between those who died of leukemia and those who didn't." Dr. Cole states in his report, however, that available data suggests the leukemia-af flicted cases were "more heavily exposed"
to the chemical. -Dr. Cole reported that it was very
possible that an abnormal rate of leukemia would continue at the Wood River facility. Shell never relayed this comment to workers there.
Reports to Workers
Dr. Cole said he wasn't familiar enough with Shell's reports to its workers about his research to comment. He added that If the choice were his, he would tell em
ployees that benzene was the "likely cause" of the leukemia problem at the Illi nois refinery.
Shell says that in reporting Dr. Cole's study in company bulletin board announce
ments, it didn't try to explain all of the re port's details. "We made some judgments on interpreting and summarizing," a com
pany spokesman said this week. As for whether the leukemia victims were more heavily exposed to benzene than other workers. Shell says the report's data wasn't consistent. "You could argue it ei
ther way," the spokesman said. As for Dr. Cole's comments that more
cancer deaths were possible, Shell said it believed it conveyed this idea simply by reporting on the study. Shell also said it discussed Dr. Cole's report with workers in plant discussion groups, but it didn't elabo rate on what was said.
George Machino, vice president of Lo cal 525 of the International Union of Oper ating Engineers, which represents about 500 Wood River workers, said he believes
that even if Shell only suspected that the leukemia deaths were benzene-caused, it had a duty to alert workers.
"Even if it's not scientific, but only sup
position by the people contracted to do the study, we should have been told, " said Mr. Machino, who also heads a committee of several unions working with Shell on health and safety issues at the Illinois plaint.
A Shell spokesman said a complete text of Dr. Cole's reports wasn't given to union officials at the Wood River facility. He said the union hadn't asked for it until yester day, and that it would be provided.
Since the mid-1970's, Shell has tested re finery workers at Wood River and other lo cations for reduced white blood cell or platelet counts, the spokesman said. Signif icant lowering of either can indicate a pre leukemia condition. The spokesman said that as a result of the monitoring program, two Wood River workers had been re moved from jobs where they had been ex posed to benzene.
An official of the National Institute of Occupational Safety and Health, a federal agency that investigates workplace haz ards, recently criticized Shell in a letter for being "overly reassuring" in telling
workers about the health risks of ben zene.
While Shell has maintained in employee communications that leukemia is linked to
"high" benzene exposure levels, a NIOSH official noted that leukemia also has been found in workers exposed to low levels of benzene, "We believe that it is not possible to firmly establish a (benzene exposure* level at which one is assured that no risk exists," J. Donald Millar, NIOSH's assis tant surgeon general, wrote to Shell in Sep tember 1983.
Shell says that during the 1950s and 1960s benzene levels in the air at its refin eries were as high as 100 parts per million. But it Insists current levels are "far be low" federal standards, which limit expo sure to 10 pm.
In 1978, OSHA tried to lower the ben zene worker exposure standard to one part per million, but that attempt was over turned in a Supreme Court decision follow ing an industry challenge. OSHA promised
a stronger benzene rule last summer, but none has been proposed yet.
