ON THE COVER: Rising up like an island in the sea is the concentration of chromium in a square millimeter of soil taken from a polluted San Francisco Bay wetland. This computer image, generated on the x-ray fluorescence microprobe beamline of LBL's Advanced Light Source, shows that chromium is drawn to highly localized chemical "hot spots" in the soil. The color scale ranges from blue, which is no chromium, to red-orange, which is a concentration of one picogram per micrometer. See the article, "Activating Alkanes."
