Patterns of agricultural pesticide use in relation to socioeconomic characteristics of the population in the rural U.S. South.
Residents of rural, agricultural areas where pesticides are used experience increased potential for pesticide exposure. In the rural U.S. South, where communities are predominantly of color, increased agricultural chemical use can constitute environmental injustice. Lacking data on the amounts of pesticide applied, the authors used county-level expenditure on agricultural chemicals as a proxy for pesticide use to explore spatial patterns of pesticide expenditure in relation to racial and economic composition in 953 rural counties in 12 southern states. Approximately eight times more money was spent on pesticides in counties with populations having more than 40 percent persons of color than in counties with less than 6 percent. Approximately four times more money was spent in counties with more than 22 percent of their population living in poverty than in counties with less than 12 percent. After adjusting for agricultural land area and land use, the authors found counties with more than 40 percent persons of color and more than 22 percent poverty spent about $1.3 million more on pesticides in 2002 than did counties with less than 6 percent persons of color and 12 percent poverty. This pattern of pesticide expenditures may produce racial and economic inequities in environmental exposures to pesticides, having implications for environmental justice and public health.
