Breathing fog in California's San Joaquin Valley may be more dangerous than inhaling polluted air because particles of pesticides, chemicals and vehicle exhaust fumes accumulate in much higher concentrations in fog, scientists reported today. "There is a difference between inhaling vapors (in air) and inhaling concentrated particles (in fog). The particles stay in the lungs, whereas vapors can be exhaled," said James N.

The oil company that gave the world the Exxon Valdez oil spill hopes to score some environmental points with consumers by introducing lower-emissions gasolines in California today, joining three other refiners already selling such fuel here. Exxon Corp., the West Coast's fifth-largest retailer of gasoline last year, is expected to unveil a reformulation of its Exxon Extra premium unleaded gasoline at about 175 stations in the Los Angeles area.

California residents will be protected from highly toxic dioxins emitted into their neighborhoods under a new state rule that will force more than 100 hospital incinerators to shut down within a year, air quality officials said Monday. The hospitals and health-care centers, which use the incinerators to burn infectious medical waste along with regular garbage, must cut dioxin fumes by 99% under a regulation adopted Friday by the California Air Resources Board.

Smog is bad. Gasoline-fueled cars contribute to smog. Therefore, replacing them with electric cars will reduce smog. Not necessarily so, says a team of researchers whose study on air quality and electric vehicles appeared last week in a journal published by the American Chemical Society.

Ruling that environmental advocates failed to prove that the public faces a significant cancer risk from breathing diesel exhaust, a state judge in San Francisco has dismissed a major lawsuit against companies that manufacture engines. The judge threw out the case because the group that filed suit, the Corporation for Clean Air, did not provide scientifically valid evidence proving its claim against Navistar International, General Motors, Ford, Chrysler and five other corporations.

The California Air Resources Board may consider lowering the amount of sulfur allowed in the state's gasoline so autos can more effectively cut smog-producing emissions. The board's staff has drafted a preliminary proposal to lower the amount of sulfur allowed in gas from a maximum of 80 parts per million for any single batch to a maximum of 20 ppm to 30 ppm, according to documents released Monday.

California's already severe electricity squeeze could tighten further this summer if regulators don't ease up on air pollution rules, power company officials said Friday. The state's 1,000 power plants--many aging and burning natural gas--have been running so hard and long in this summer of electricity scarcity that many are close to spewing as much pollution as they are allowed for the year under their permits.

California's power plants are spewing large quantities of extra air pollution during the state's energy crunch--setting the stage for a high-stakes conflict between power producers and air quality regulators as the energy shortage continues. Earlier this month, regulators received a taste of problems to come when energy company AES Pacific Inc.
