Distribution of community location along the highway by hair total
mercury (μg/g), fish consumption index, and community variation. The
x-axis for all graphs is the relative distance (in km) of each community along
the highway, starting with the most western community in the study. Figure 2a
shows the road altitude, location of select communities and location of all
rivers that cross the highway (in blue vertical bars); Figure 2b shows the
average H-THg and 95% confidence interval (CI) by community along the highway;
Figure 2c is average fish consumption index level by community along the
highway; and Figure 2d is the community random intercept and 95% CI from an
intercept-only model that partitions variance among individuals, households and
communities. Communities located in ASGM affected watershed are denoted in blue
while those in non-ASGM-affected watershed are denoted in brown.
