Table 5-1. Human studies of exposure to diesel exhaust (continued)
Description
Pilot study of 129 bus company
employees classified into three
diesel-exhaust exposure ·
categories: clerks (0), bus
drivers (I), and bus garage
workers.
Cohort of 694 male bus garage
employees followed from 1951
through 1983 was evaluated for
mortality from cardiovascular
disease. Subcohorts categorized
by levels of exposure were
.clerks (0), bus drivers ( 1 ), and
bus garage employees (2).
Findings
The most heavily exposed group (bus garage
workers) had a fourfold increase in risk of dying
from cardiovascular disease, even after correction
for smoking and allowing for 10 years of exposure
and 15 years or more of induction latency time.
No increased mortality from cardiovascular disease
was found among the members of these five bus
companies when compared with the general
population or grouped as subcohorts with different
levels of exposure.
