Title: Manganese accumulation in soil and plants along Utah roadways: A possible indication of motor vehicle exhaust pollution

Abstract

An organic manganese compound is currently added to gasoline to replace tetraethyl lead as an antiknock fuel additive in the U.S. and Canada. Combustion exhaust gases contain manganese oxides. Manganese oxides are known to cause various deleterious health effects in experimental animals and humans. A field survey of roadside soil and plants in central Utah revealed that soil manganese concentrations in high traffic areas were up to 100-fold higher than historic lead levels. Soil manganese concentrations were highly correlated with distance from the roadway. In addition, roadside aquatic plants were higher in leaf tissue manganese than herbs or grasses. Submerged and emergent aquatic plants were sensitive bioindicators of manganese contamination. Manganese concentrations in soil and in some plant species along impacted roadsides often exceeded levels known to cause toxicity. We conclude that roadside soil and plants were apparently contaminated by manganese oxides from Mn-containing motor vehicle exhaust.
