LEAD IN A CONNECTICUT SALT MARSH

HORIZONTAL AND VERTICAL GRADIENTS IN LEAD CONCENTRATION WERE MEASURED IN A TYPICAL CONNECTICUT COASTAL SALT MARSH. HIGHEST CONCENTRATIONS OF LEAD OCCURRED AT THE SURFACE, DECREASED DOWNWARD TO BETWEEN 20-30 CM AND WERE QUITE STABLE BELOW 30 CM. THE OPINION IS GIVEN THAT THE INCREASING CONCENTRATION OF LEAD IN THE UPPER FEW CM REPRESENTS THE INCREASING AMOUNTS OF LEAD INTRODUCED INTO THE MARSH WITH INCREASED USE OF GASOLINE WITH TETRAETHYL LEAD SINCE 1935 OR EARLIER, AND THAT THE MAJOR SOURCE OF LEAD IN THE MARSH IS THROUGH RUNOFF FROM THE PAVED HIGHWAY AND STREET SYSTEM OF THE URBAN COMPLEX SURROUNDING THE MARSH. /AUTHOR/
