Eosinophil and monocyte and basophil counts
are about the samein the exposed as in the unexposed groups. The eosinophil counts were quite
high in both exposed and comparison populations,
but were about the samein the two groups. In
their differential counts, 45% of the exposed and
533% of the unexposed had eosinophils of 5% or
greater.

ever, above this age the distribution of counts is
about the same.
The mean of the lymphecyte counts shows an
increase since last year’s counts of 33% in the exposed groups (Figure 9). It is this increase in
lymphocytes that accounts for therise in the total
