San Francisco, Bay Area

Solar salt operations can be found along the shores of the Great Salt Lake and in the San Francisco Bay area (6—10). Salt production from these areas represents 10% of the total salt produced in the United States. 

HORN-ROSS P L, HOGGATT K J, LEE M M (2002) Phytoestrogeus and thyroid cancer risk the San Francisco bay area thyroid cancer study. Cancer Epidemiol Biomarkers Prev. 11 43-9. 

An inverse correlation between thyroid cancer risk and phytoestrogens was recently proposed as a result of a multi-ethnic population-based case control study conducted in the San Francisco Bay Area (Hom-Ross et al., 2002). In this study, dietary habits and phytoestrogen consumption were assessed by a food-frequency questionnaire and by a nutrient database. The outcome of the study was that soy-based foods and alfalfa sprouts were associated with a reduction of thyroid cancer risk, whereas a Western diet did not influence cancer risk. No difference was observed between American and Asian women or between pre- and postmenopausal women. Furthermore, among the few compounds examined, the isoflavones genistein and daidzein and the lignan secoisolariciresinol were the phytoestrogens most frequently associated with risk reduction (Horn-Ross et al., 2002). 

An inscribed thick plate of brass attributed to the landing, in 1579, of Francis Drake on the coast of California, is retained in safekeeping at the University of California, Berkeley. Since its discovery, in the San Francisco Bay area in 1936, however, there have been doubts about the authenticity of the plate, although an early chemical study had apparently confirmed its authenticity. Regardless of this initial study, doubts about the origin of the plate persisted, and a new study, based on the composition of the brass as determined by neutron activation, X-rays fluorescence, and atomic absorption analysis was initiated to reevaluate the earlier authentication of the plate. The results of this study were then compared with the composition typical of brass from Drake s time as well as from modem brass, and it was then concluded that the plate was probably made during the latter part of the nineteenth century or the early years of the twentieth century (Hedges 1979). 

Ann McCampbell, M.D., is a graduate of the UCLA Medical School and became a licensed physician in California in 1979. She completed an internship in internal medicine in Santa Barbara, and practiced in the field of women s health for five years at the University of California Santa Barbara Student Health Center, and at Kaiser Permanente in the San Francisco Bay Area. Off-hours she played drums in a rock and roll band, and played competitive beach volleyball. 

In 1982, many more cases of drug addicts becoming frozen after injecting themselves with (what they thought to be) heroin were reported by various emergency rooms in the San Francisco Bay area. Neurologists, psychiatrists, and... 

My first two interactions with the world of US Government chemical warfare were in the 1950s or maybe the 1960s when I was still a senior research chemist at the Dow Chemical Company in the San Francisco Bay Area. They were totally opposite in the images of secrecy and research process that they presented. I kept no notes, so all is from ancient memory.

When the same observers examined mortality from chronic respiratory diseases other than cancer of the lung, the death rates were found to be somewhat higher in Los Angeles than in the San Francisco Bay area and San Diego County, particularly among persons who had lived for 10 or more years in the same area. It is well known, however, that socioeconomic class is an important factor in mortality from chronic respira-...

Phase 2 RFG was introduced in the San Francisco Bay Area and pollutant emissions were measured at the 1100 m long Caldecott tunnel during the summers of 1994 and 1997. Between the 1994 to 1997, emissions of carbon monoxide decreased by 31%, non-methane volatile organic compounds (VOC) decreased by 43%, nitrogen oxides decreased by 18%, and vehicle emission of benzene was estimated to be a 30 to 40% reduction. The use of RFG increased formaldehyde...
