<p><strong>Exeter, CA</strong><hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"> A recent University of California study shows that air quality can benefit from citrus trees. In a study commissioned by California Citrus Mutual and the Citrus Research Board conducted by Dr. Karlik of the University of California Cooperative Extension, Bakersfield, citrus trees have been found to positively contribute to air quality in the Central Valley. The study was conducted in a citrus grove in Tulare County. Citrus acts as a sink for the deposition of ozone and other trace gases. On an annual basis, citrus trees absorb an estimated 9,000 tons of ozone. This is comparable to the amount absorbed by a plantation of Ponderosa pines, according to a press release.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"> Plant material contributes to ozone to an extent through the production of biogenic volatile organic compounds or BVOC and includes isoprene, generally considered to have the most negative effect on air quality. But the study concluded that while citrus may contribute BVOC, it is a minimal amount and isoprene was almost zero. Emissions were found to be less than California Oak, Eucalyptus and Pines.<hr class="legacyRuler"><hr class="legacyRuler"><hr class="invisible minimal-padding"><a class="btn btn-sm btn-primary col-lg-12" style="white-space: normal;" href="http://www.cacitrusmutual.com" target="_new">California Citrus Mutual</a></p><hr class="legacyRuler"><hr class="invisible minimal-padding">
