Abstract
In areas with high lead emission from the exhaust of vehicles, insects contained averages of 10.3, 15.5, and 25.0 ppm lead (oven dry weight) for species that suck plant juices, chew plant parts, and prey on other insects respectively, indicating a biological concentration of lead from herbivore to carnivore trophic levels. In low lead emission areas insects in the same feeding categories had average lead contents of 4.7, 3.4, and 3.3 ppm respectively and showed no significant differences.Keywords
