Design: cross-sectional cohort<br />

Subjects: adult male Pb scrap refining<br />

workers (n = 10), mean age 41.1 yr (SD 7.3,<br />

range 28–54); age-matched reference<br />

subjects (n = 10)<br />

Outcome measures: PMN chemotaxis (C5 or<br />

FMLP) and phagocytosis (FMLP)<br />

Analysis: comparison <strong>of</strong> outcome measures<br />

between worker and reference groups,<br />

correlation<br />

Design: cross-sectional cohort<br />

Subjects: adult male TEL manufacture<br />

workers (n = 39) mean age: 45.1 yr; and<br />

age-matched reference subjects (n = 21);<br />

mean age 32.2 yr<br />

Outcome measures: serum IgA, IgG, IgM;<br />

mitogen (PHA)-induced<br />

lymphoblastogenesis; and NK cell<br />

cytotoxicity<br />

Analysis: comparison <strong>of</strong> outcome measures<br />

<strong>for</strong> exposed and reference groups<br />

Design: cross-sectional cohort<br />

Subjects: adult male battery manufacture<br />

workers (n = 39), mean age 33.9 yr (SD 12.1,<br />

range 18–56); reference subjects (n = 39)<br />

matched by age and race<br />

Outcome measures: PMN chemotaxis<br />

(endotoxin LPS); phagocytic (endotoxin<br />

LPS) respiratory burst activity (NBT<br />

reduction)<br />

Analysis: nonparametric comparison <strong>of</strong><br />

outcome measures between worker and<br />

reference groups<br />
