Um...okay. <br /><br />-Wortley Et Al, "Exposure To Secondhand Smoke In The Workplace: Serum Cotinine By Occupation," Jnl OCC & Env Med, 2002; 44 (6) (*) Personal Correspondence w/ Lead Author <br /><br />Nor is this study a breakthrough in any way. Remember, the serum measured here is blood, not urine. According to a study sponsored by ALA, the blood cotinine levels in less than pack-a-day smokers ranged from 182- 249 ng/ml. That's a quantum difference from the 0.62 reported by Wortley among nonsmoking wait staff. <br />- Ahijevych Et Al, In "Addiction Behaviors, " Feb, 1999 <br /><br />And yet. <br /><br />And yet. A study by James Repace measured the urine cotinine in waiters in Hong Kong and projected, solely on the basis of their cotinine, that 150 would die. <br />-"Passive Smoking And Risk For Heart Disease And Cancer," Hedley, Repace <br /><br />But cotinine (have we mentioned?) is a harmless metabolite that indicates nothing except exposure to nicotine (or nightshade vegetables) But, hey, let's say it again: <br /><br />"It is not known how levels of cotinine measured relate to the biologically important components of ETS other than nicotine." -Nyberg, Op Cit <br /><br />Which leaves us with the general workplace studies--all epidemiological-- of which there aren't many. The largest American study ever done (and sponsored in part by The National Cancer Institute) "Passive Smoking and Lung Cancer in Nonsmoking Women," Brownson et al., 1992, reported: <br /><br />"... no elevated lung cancer risk associated with passive exposure in the <br />workplace." <br />-American Jnl Of Public Health, Nov. 1992 <br /><br />Alas, complained EPA, this study (published in November '92) arrived "too late" to be included in their (1993) report. Had it been so (the largest study ever done!) and been thrown into the hopper, it would have so tilted the weight that ETS could not, not even with lots of fudging, have been classified as a risk or a Class A carcinogen. <br /><br />As of 1995, there were 8 extant studies that looked into the workplace/ lung cancer data. According to one set of researchers: <br /><br />"An EPA-style meta-analysis...demonstrates no statistically significant <br />association for the data in its entirety--or for any sub-group of American workers. The pooled risk estimate [is] 1.0." <br />-"ETS Exposure, Lung Cancer And Heart Disease", Sears, Steichen, OSHA <br /><br />The studies were pooled into that "EPA-style meta-analysis" because, the authors say, their results were so contradictory and mixed. Two showing a slightly increased risk; two showing a slightly decreased risk, and the rest indeterminate. <br /><br />The same authors point out that "it is difficult to draw any conclusions concerning heart-disease risk in the US workplace because virtually no such information on the US workplace exists." <br /><br />None of this, however, prevents the zealots from hollering Wolf or stops them from conjuring baseless death tolls, easily shattered by science and sense. Take, for example, this crowning lulu from Mayor Bloomberg of NYC.<br /><br />http://www.nycclash.com/CaseAgainstBans/RestaurantAir.htmlAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3585028625507474093.post-4561244554627384072011-12-15T19:31:49.769+00:002011-12-15T19:31:49.769+00:00THE COTININE FACTOR
To begin with, by far the mo...THE COTININE FACTOR <br /><br />To begin with, by far the most plentiful-- and measurable-- part of a cigarette (either first or secondhand) is simply: the nicotine. The body then metabolizes nicotine into cotinine. Smoking, however, isn't the only source of cotinine. The body also metabolizes foods into cotinine--tomatoes, potatoes, eggplant, and various teas. <br /><br />In fact, another study showed that eating a normal (4.9 oz) portion of mashed potatoes produced the same amount of cotinine as 4 hours spent having drinks in a smoky bar. And similarly, a rather long lunch with a smoking friend can be easily equaled by a third of an ounce of eggplant. <br />-"Relevance Of Nicotine Content Of Common Vegetables To The Identification Of Passive Tobacco Smokers," Domino Et Al, Med. Sci. Res, 1993; 21, 571-2; Similarly, New England Jnl Med, Aug, 1993 <br /><br />Further, too, it's been noted that cotinine is only used as a "marker" (for exposure to ETS) because it's possible to measure. Even the California EPA has admitted, as most studies do, that the harmless "cotinine does not serve well as a marker for the presence of other tobacco smoke compounds." <br /><br />Then too there's this: <br /><br />"There exists between individuals a genetically determined variation (up to 50 fold) in the level of metabolism to cotinine from a given exposure. " <br />-Nyberg Et Al "Misclassification Of Smoking Status,.." Epidemiology, May 1997 <br /><br />And this: <br /><br />Men metabolize cotinine faster than women, and whites faster than blacks (by 30%) This would also apply to the cotinine metabolized out of potatoes. And would indicate that either-- and/or-- women and blacks would register higher levels than their white / male counterparts to identical exposures. Further, eating a meal can affect metabolic speed. <br />-"Nicotine Metabolism Variables," Ahijevych Et Al/Agency For Health Care Policy & Research (HS07373) <br /><br />Nonetheless, it's used as a marker. <br /><br />Okay-- let's get a baseline. Again, according to the government (NIOSH Bulletin 54) a study by Cummings et al in 1990, showed the average concentration of urinary cotinine in a pack a day smoker is approximately 1,200 ng/ml. <br /><br />Another study, conducted by the National Research Council in 1986, showed the average amount in a smoker was 1,825 ng/ml. <br /><br />Another study, also reported by NIOSH, found that restaurant workers who themselves didn't smoke, had urine concentrations of 56 ng/ml. About 1/20th to 1/37th of the cotinine in a smoker. <br /><br />And please remember that cotinine is a harmless metabolite and a rather poor indicator of anything else in smoke. <br /><br />Nonetheless, in a recent study (Wortley et al, a study the Mayor likes) the blood levels of cotinine were carefully measured in 50 nonsmoking restaurant workers, for a mean serum level of 0.62 (ng/ml.) or 6/10th of a nanogram. This was higher than the levels recorded in, say, farmers (0.13) <br /><br />Yes?

Benowitz and colleagues (1983) originally proposed 10 ng/mL as a reasonable cutoff level for cotinine in serum to distinguish between smokers and nonsmokers. Consistent with that proposal, Repace and Lowrey (1993) estimated median serum cotinine levels to be about 1 ng/mL for U.S. adult nonsmokers and about 10 ng/mL for the most heavily exposed nonsmokers.<br /><br />still page 110Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3585028625507474093.post-64087024083230509222011-12-15T18:07:20.104+00:002011-12-15T18:07:20.104+00:00pg 110

The authors attributed the relatively poor specificity to “deception” in the self-reports of some participants with high serum cotinine levels. When the investigators reclassified those believed to be deceptive as smokers, sensitivities were 96 to 97 percent and specificities were 99 to 100 percent using plasma, saliva, or urine cotinine as the biomarker for comparison. The optimal cutoff values in this study were 14.2 ng/mL in saliva and 49.7 ng/mL in urine (Jarvis et al. 1987).<br />Pirkle and colleagues (1996) used a serum cotinine cutoff level of 15 ng/mL in a large U.S. epidemiologic study. They found a strong agreement with the self-reported nonsmoking status of the participants: those with serum cotinine levels above 15 ng/mL who claimed no tobacco use comprised only about 1.3 percent of the adult participants and 2.6 percent of the adolescents. Caraballo and colleagues (2001) examined the participants in this study aged 17 years<br />and older in detail and used the same nominal cutoff<br />of 15 ng/mL. There was a 92.5 percent agreement between serum cotinine concentrations and self-reported active smoking status and a 98.5 percent agreement among self-reported nonsmokers. The researchers regarded the infrequent or low rate of<br />cigarette use as an explanation for the disagreement with serum cotinine levels among self-reported smokers in most cases.

(August 1991), pp. 88-105.<br /><br />Abstract<br />Environmental tobacco smoke (ETS) is derived from cigarette smoldering and active smoker exhalation. Its composition displays broad quantitative differences and redistributions between gas and respirable suspended particulate (RSP) phases when compared with the mainstream smoke (MSS) that smokers puff. This is because of different generation conditions and because ETS is diluted and ages vastly more than MSS. Such differences prevent a direct comparison of MSS and ETS and their biologic activities. However, even assuming similarities on an equal mass basis, ETS-RSP inhaled doses are estimated to be between 10,000- and 100,000-fold less than estimated average MSS-RSP doses for active smokers. Differences in effective gas phase doses are expected to be of similar magnitude. Thus the average person exposed to ETS would retain an annual dose analogous to the active MSS smoking of considerably less than one cigarette dispersed over a 1-year period. By contrast, consistent epidemiologic data indicate that active smoking of some 4–5 cigarettes per day may not be associated with a significantly increased risk of lung cancer. <br /><br />http://www.citeulike.org/user/vmarthi...<br />...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3585028625507474093.post-65204487836872777642011-12-15T14:01:35.853+00:002011-12-15T14:01:35.853+00:00Gilmore is claiming that smoke exposure is directl...Gilmore is claiming that smoke exposure is directly proportional to cotine level.
