Editorial Mote. Because there is no agreed-upon definition of heatstroke or of the other illnesses that make up most heat-related mortality, a retrospective assessment of all death certificates within the affected areas will be needed to determine the impact of this heat wave. At this time, since there are unavoidable delays in reviewing death cer tificates in most jurisdictions, CDC has no estimate of heat-related mortality.
The preliminary data reported above concur with published analyses of previous heat wave mortality in the United States in implicating poverty as an important risk factor (7) In possible contrast to the reports of large numbers of deaths in elderly people
and urban residents in previous heat waves, the St. Louis data suggest that the additional deaths this year as compared to 1979 were not confined to the over-65 age group. The definitive results from Arkansas are expected to be useful in estimating the potentially considerable numbers of rural residents experiencing heat-related mortality. Reference 1.

Glioblastoma Cluster in a Chemical Plant -- Texas
In November 1978, a Texas petrochemical worker informed a local office of the Occupational Safety and Health Administration (OSHA) that he and several of his former coworkers had been diagnosed as having brain cancer. Epidemiologic investigation was undertaken and, while still ongoing, has identified 18 deaths due to orain tumor in former employees of a large, diversified, petrochemical plant on the Texas Gulf Coast (7). The workers' death certificates listed malignant, benign, or unspecified primary brain tumors* as the primary cause of death. Review of additional information has revealed that 15 of the 18 tumors were glioblastomas. Of the remaining 3, 2 were meningiomas and 1 was an astrocytoma grade I
To determine whether this number of cases exceeds the expected, a cohort mortality study was initiated. Seventeen of the 18 cases met the study's case definition (death certificate diagnosis of brain tumor, white male, date of death between 1940 Bnd 1979) After appropriate adjustment for year of death and age at death. 11.2 such cases would have been expected (SMRt = 152) Preliminary analysis revealed a trend of increasing excess mortality with increasing length of employment t<10 years, SMR = 95,10-<20 years, SMR = 131,>20 years, SMR =304)
Preliminary review of work records for the 18 cases reveals no obvious common exposure factor within the plant The cohort mortality study, a case-control study, and characterization of potential industrial exposures will continue.

Editorial Note: Bram cancer has been associated in humans with only 1 occupational agent, vinyl chloride 12). although numerous other agents, such as acrylonitrile, cause
brain cancer in animals (3) Epidemiologic investigations have shown excesses of brain tumor m chemists ) and associations between brain tumor and employment in oil refineries and chemical plants iSfi). v The uniformity of cell type among these cases distinguishes this group from clinical , series in which greater histologic variety is noted Glioblastoma multiforme was, however, the predominant cell type among brain tumors in workers exposed to vinyl chloride {2).
Since determination of vital status is complete in only 47% of the cohort in this study (3,106 out of 6,677 workers) and because the expected number of cases is calcu lated by assuming that those workers not yet located are still alive, the estimated SMRs probably underrepresent the true excess of brain tumor mortality in this population.
Determination of a causative agent in this episode awaits further study. References 1 Alexander V, Lelfmgwell S, Lloyd W, Waxweiler R, Miller R Brain cancer in petroleum workers-

Follow-up on Mount St. Helens
July 22 eruption of Mount St. Helens Mount St. Helens erupted 3 times on the evening of July 22. The eruptions (and
their approximate duration) were at 5:13 pm (2 minutes). 6 26 pm (10 minutes), and 7 00 pm (3 hours), and effectively blew out the developing dome.
Individuals with permits to be on the mountain were cleared from the hazardous zone aftBr the earthquake activity began; no fatalities occurred. There was some pyroclastic flow in the direction of the Spirit Lake area, but no mudflows or significant ashfall on the mountain. These eruptions, therefore, should not significantly increase any exist ing risks of flooding or other dislocations in the area.
The ashfall was east-northeast of the mountain, in the general direction of the plume from the first eruption on May 18, although the total ashfall was less. The most heavily affected area was in northeast Washington, north of Spokane The hospitals in the CDC surveillance network, as well as other hospitals in the plume trajectory, rapidly provided unofficial estimates of ashfall in their communities Ait of the hospitals reported a 0to 1/8-mch accumulation, except in an area in northeast Washington (including Chewelah, Coiville, Ruby, and Metalme Falls--all north of Spokane), where 1/8-1/4 inch of ashfall was reported.
Preliminary data on total suspended particulates (TSP) from the Environmental Pro tection Agency (EPA) Region X (Table 1) showed TSP increases in the plume path during the 24-hour post-eruption period, the peak levels measured were considerably lower, however, than those measured after the May 18 eruption. Addy, which is In the area that received the heaviest fallout, had an unconfirmed report of TSP of 4,497 jig/m3. Yakima and Richland, on the fringe of the plume, and Spokane showed lesser increases.
