As Paul Robbins reports in “Lawn People” (2007), the first pesticide popularly spread on lawns was lead arsenate, which tended to leave behind both lead and arsenic contamination. Next in line were DDT and chlordane. Once they were shown to be toxic, pesticides like diazinon and chlorpyrifos—both of which affect the nervous system—took their place. Diazinon and chlorpyrifos, too, were eventually revealed to be hazardous. (Diazinon came under scrutiny after birds started dropping dead around a recently sprayed golf course.) The insecticide carbaryl, which is marketed under the trade name Sevin, is still broadly applied to lawns. A likely human carcinogen, it has been shown to cause developmental damage in lab animals, and is toxic to—among many other organisms—tadpoles, salamanders, and honeybees. In “American Green” (2006), Ted Steinberg, a professor of history at Case Western Reserve University, compares the lawn to “a nationwide chemical experiment with homeowners as the guinea pigs.”
Meanwhile, the risks of the chemical lawn are not confined to the people who own the lawns, or to the creatures that try to live in them. Rain and irrigation carry synthetic fertilizers into streams and lakes, where the excess nutrients contribute to algae blooms that, in turn, produce aquatic “dead zones.” Manhattanites may not keep lawns, but they drink the chemicals that run off them. A 2002 report found traces of thirty-seven pesticides in streams feeding into the Croton River Watershed. A few years ago, Toronto banned the use of virtually all lawn pesticides and herbicides, including 2,4-D [a major ingredient in Agent Orange] and carbaryl, on the ground that they pose a health risk, especially to children.
