A comparison of soil chemical characteristics: urban
and rural gradients of Baltimore and New York, and
cities of Baltimore and Budapest.

Soils located in metropolitan areas are known to be
contaminated by heavy metals. In this poster, we
investigate the spatial distribution of the heavy
metals along with other characteristics such as
organic matter and pH in surface soils in the cities
of Baltimore and Budapest. Principal component
analysis was performed on the data as a reduction
technique to determine components or factors which are
weighted combinations of the input variables.
Regional patterns of heavy metal concentrations can be
explained by geochemical properties of mineral soil
and parent material, and atmospheric deposition.
