— Air officials for years have blamed dairy cow emissions for the unusually
high ozone levels in California’s San Joaquin Valley, but a new study points
more to what goes into the animals than what comes out.
The study — funded by the
U.S. Department of Agriculture, California Air Resources Board and the San
Joaquin Valley Air Pollution Control District — initially was intended to
measure the impact of animal manure, urine and flatulence on ozone levels.
