Burning of fossil fuels raises chemicals into the air that react on earth’s surfaces.

Under the circumstances, this previously unknown chemistry could account for up to 40 parts per billion of ozone – nearly half of California’s legal limit on outdoor air pollution.

Ozone can cause coughing, throat irritation, chest pain and shortness of breath. Exposure to it has been linked to asthma, bronchitis, cardiopulmonary problems and premature death.

“Realistically, this phenomenon probably accounts for much less than 40 parts per billion, but our results show it could be significant. We should be monitoring it and incorporating it into atmospheric models,” said Barbara Finlayson-Pitts, Distinguished Professor of Chemistry and lead author of the study. “We still don’t really understand important elements of the atmosphere’s chemistry.”

UCI scientists explained; when nitrogen oxides combine with hydrochloric acid from airborne sea salt on buildings, roads and other particles in the air, highly reactive chlorine atoms are created that speed up smog formation.

The study was undertaken by scientists involved with AirUCI, an Environmental Molecular Sciences Institute funded by the National Science Foundation. UCI’s Jonathan Raff conducted experiments; Bosiljka Njegic and Benny Gerber made theoretical predictions; and Wayne Chang and Donald Dabdub did the modeling. Mark Gordon of Iowa State University also helped with theory.

Nowadays, forests around the world are being destroyed to make tissue products, however you can help stop this terrible action by pressing producers to use recycled content and clean manufacturing processes.

Tips: Making Smart Shopping Decisions To Save Forests
1. Buy paper products with recycled content – especially post-consumer fibers.
Look for high recycled content products, post-consumer fibers are recovered from paper that was previously used by consumers.

2. Buy paper products made with clean, safe process.
Tissue products are bleached to make them whiter and brighter(they put more chlorine in bleached processes). Look for products labeled otally chlorine-free (TCF) or processed chlorine-free (PCF). In some cases, elemental chlorine-free (ECF) may be acceptable.

3. Tell tissue manufacturers to stop using virgin wood for throwaway products.
Tell the brand company to use more recycle fibers, if that brand doesn’t have any recycled content.

Saving forests  also helps reduce global warming pollution.

Make your office more environmentally friendly. Try these tips.

  • Consider for compressed work weeks and/or use less telecommuting to reduces commuting and traffic, leading to fewer automobile emissions.
  • If can, be better use laptop as it consumes less energy than a typical desktop PC.
  • Think before you print. Make sure you print only what is necessary.
  • Use both sides of a piece of paper. Try to reuse envelopes as many times as possible.
  • Instead of disposable cups, use glasses, mug or water bottle.
  • Be Consider refillable pens and mechanical pencils rather than disposable ones.
  • Use paperclips rather than adhesive tape.
  • Use crayons or colored pencils instead of solvent-based markers.
  • Make sure you select a sleep or stand-by mode for your copy machine, printer and fax when unused.
  • Turn off your computer and the power strip when you leave. Set a sleep mode for your computer while you are away for short time.
  • Switch out your old standard light bulbs with energy saving bulbs.
  • Turn off the lights when you’re leaving the room for 15 minutes or more. Use natural light if possible.
  • Put it into action and share these with your colleagues.
