A statistical summary of the chemical analysis for dry de-
position samples are presented in Table 1. The concentration of
heavy metals showed a wide range in concentrations within
thesame quadrant due to the fact that, within the same quadrant, the
sampling sites were distributed over a wide area—some close to
the source of pollution showing high concentrations and others
in the same quadrant but further away from the source show-
ing low concentrations. The average concentration levels of se-
lected heavy metals (Mn, Cu, Ni, Co, Pb, Cd, Zn, Cr, Al, and
Fe) within the four directional quadrants are shown in Figure 2.
Initial qualitative observation of the average concentration re-
sults for each quadrant indicates thatNi and Fewere higher in the
southwest quadrant; Pb,Cu,Co, andCdwere higher in the north-
west quadrant; Zn andMnwere higher in the southeast quadrant;
and Al and Cr were higher in the northeast quadrant. Mo was
low and approximately equal in concentration throughout the
study area.
Because the mean concentration of heavy metals appeared
unequal in most of the investigated sites, one-way analysis of
variance (ANOVA) was carried out to test the signi?cant differ-
ences betweenmean concentrations of heavymetalswith respect
to the sampling quadrants. The results of the test showed that
signi?cant statistical differences (at a level of α = 0.10) were
found for Pb (P = 0.082) and Cu (P = 0.081) in the northwest
quadrant. All other differences in mean concentrations of heavy
metals were found to be not statistically signi?cant by quadrant
within the range of sampling distances used from the cement
plant. This lack of statistical signi?cance is considered to be
due to the in?uence of the cement industry operations on the
local air quality throughout Fuhais City. Cu and Pb were signi?-
cantly correlated in the northwest, where they are considered to
be directly related to the heavy traf?c pattern for trucking and
automobiles transporting raw and ?nished materials in and out
of the cement factory.
