Economic assessment of the effects of air pollution on agricultural crops in the San Joaquin Valley. Final report

The study quantifies the economic value of ozone and sulfur dioxide induced agricultural losses in the San Joaquin Valley of California. In 1978, the economic impact of air pollution on crops in the San Joaquin Valley was estimated to exceed $117 million (in 1978 dollars). Over 98 percent of these losses are attributed to ozone. The economic losses from exceeding the California hourly ozone standard of 10 pphm were $106 million. These estimates are thought to be lower bounds on the economic damages from air pollution, because conservative assumptions and methods were used throughout this analysis.
