cer, such as auramine manufacture, boot <strong>and</strong><br />
shoe manufacture <strong>and</strong> repair, coal gasification,<br />
coke production, magenta manufacture, painter,<br />
rubber industry, hairdressers or barbers, petroleum<br />
refining, dry cleaning, printing processes <strong>and</strong> the<br />
textile manufacturing industry [87]. Studies of<br />
bladder <strong>cancer</strong> among workers in the dyestuffs<br />
industry, <strong>and</strong> later among rubber workers, hold an<br />
important place in the history of occupational<br />
<strong>cancer</strong> [122].<br />
In the present study, occupations with several<br />
chemical exposures were listed among those with the<br />
highest SIRs. Waiters <strong>and</strong> tobacco workers were<br />
among those with the highest SIRs for lung <strong>cancer</strong>,<br />
<strong>and</strong> their excess risk for bladder <strong>cancer</strong> is therefore<br />
probably due to smoking as the major risk factor.<br />
Almost all occupational categories with a low SIR<br />
for bladder <strong>cancer</strong> also have a low SIR for lung<br />
<strong>cancer</strong>, such as gardeners <strong>and</strong> those working in<br />
agriculture <strong>and</strong> pedagogical work.<br />

From the occupations with prior finding of excess<br />
risk, hairdressers <strong>and</strong> printers were also among the<br />
occupations with the highest SIRs for bladder<br />
<strong>cancer</strong> in the present study. A number of studies<br />
have found an excess of bladder <strong>cancer</strong> among<br />
workers exposed to polycyclic aromatic hydrocarbons.<br />
Chimney sweeps are exposed to chimney<br />
soot which is rich on these chemicals, a group<br />
of compounds well documented as carcinogenic<br />
[122,123].<br />
Skin melanoma<br />
Incidence of skin melanoma in the Nordic countries<br />
was steadily increasing until the early 1990s, both in<br />
men <strong>and</strong> women (Figure 38). After that, there was a<br />
levelling-off in Norway <strong>and</strong> Finl<strong>and</strong>, but a rapid<br />
increase in Icel<strong>and</strong>.<br />
The highest SIRs of skin melanoma in men were<br />
observed among dentists (1.65, 95% CI 1.40 1.95),<br />
physicians, administrators, journalists, religious<br />
