    Notes: Abstract The ultimate goal of the research reported in this series of three articles is to derive distributions of doses of selected environmental tobacco smoke (ETS)-related chemicals for nonsmoking workers. This analysis uses data from the 16-City Study collected with personal monitors over the course of one workday in workplaces where smoking occurred. In this article, we describe distributions of ETS chemical concentrations and the characteristics of those distributions (e.g., whether the distribution was log normal for a given constituent) for the workplace exposure. Next, we present population parameters relevant for estimating dose distributions and the methods used for estimating those dose distributions. Finally, we derive distributions of doses of selected ETS-related constituents obtained in the workplace for people in smoking work environments. Estimating dose distributions provided information beyond the usual point estimate of dose and showed that the preponderance of individuals exposed to ETS in the workplace were exposed at the low end of the dose distribution curve. The results of this analysis include estimations of hourly maxima and time-weighted average (TWA) doses of nicotine from workplace exposures to ETS (extrapolated from 1 day to 1 week) and doses derived from modeled lung burdens of ultraviolet-absorbing particulate matter (UVPM) and solanesol resulting from workplace exposures to ETS (extrapolated from 1 day to 1 year).

    (Table 1) Interstitial water chemistry at DSDP Leg 73 Holes

    Description: Interstitial waters obtained from a transect east from the Mid-Atlantic Ridge on progressively older oceanic crust (Sites 519-522) indicate a general absence of concentration gradients in calcium and magnesium. The lack of gradients indicates little or no exchange of these seawater constituents with the underlying basalts. Only at Site 520, where there are increases in calcium and decreases in magnesium, do reactions in the silica-enriched zone appear to have affected interstitial water composition. At Site 524, on the eastern flank of the Walvis Ridge, large changes in calcium and magnesium occur as a result of reactions involving the volcanic materials that are both dispersed in the sediment column and present in the underlying basalts.
