"UCLA scientists have found that people who live and work near Santa
Monica Airport are exposed to high levels of air pollution -- a significant health concern that has been largely associated with major commercial airports such as LAX. The study, released Wednesday, shows that ultrafine particle emissions were 10 times higher than normal about 300 feet downwind of the runway's east end, where takeoffs generally start. The levels were 2.5 times higher than normal at a distance of about 2,000 feet. .... Officials for the Federal Aviation Administration said that air traffic control at Santa Monica has taken several steps to limit emissions from taxiing and departing aircraft. They include positioning planes so their exhaust is directed away from neighborhoods and instructing pilots not to start their engines until five or 10 minutes before they are cleared for takeoff. But Martin Rubin, a community activist involved in airport issues, disputes the effectiveness of those procedures. Aircraft are still idling for up to 30 minutes, back to back, he said, and wind can send emissions into neighborhoods despite a plane's position on the runway." http://www.latimes.com/news/local/la...,4334719.story |

The word "poison" doesn't appear anywhere in the article. The study, released Wednesday, shows that ultrafine particle emissions were 10 times higher than normal about 300 feet downwind of the runway's east end, where takeoffs generally start. The levels were 2.5 times higher than normal at a distance of about 2,000 feet. Why didn't the study compare these levels with being 300 feet downwind of an LA freeway? But Martin Rubin, a community activist involved in airport issues, So which was there first - Martin Rubin and the people in the community or the airport? |

Does he have any idea how much jet fuel that consumes, or what "idling for up to 30 minutes" would do to a regular piston GA engine? Clearly, Mr. Rubin is talking through his hat. IMHO, Mr. Rubin probably is exposed to more air pollution from recreational drugs than from SMO. -- Remove _'s from email address to talk to me. |

"The study, released Wednesday, shows that ultrafine particle emissions were 10 times higher than normal Define "normal". Compare it with levels for drivers stuck in daily commute traffic in the L.A. basin. about 300 feet downwind of the runway's east end, where takeoffs generally start. The levels were 2.5 times higher than normal at a distance of about 2,000 feet.

The which has been known for the better part of 60 years. Emissions from GA aircraft are neither something new, nor a significant fraction of total manmade particulate emissions, not even in the L.A. area. Once again, how about those commute hours? Mr. Rubin can go on at length, but that's his job; his employers should expect no less. |

If they dont like move the airport was there fist. |

"UCLA scientists have found that people who live and work near Santa Monica Airport are exposed to high levels of air pollution -- a significant health concern that has been largely associated with major commercial airports such as LAX. The study appears to be online here (not just the abstract): http://pubs.acs.org/stoken/presspac/...5f?cookieSet=1 According to it (section 3.3.2) it appears a heavy-duty diesel truck and a jet taking off yield nearly identical particle concentrations. It would seem that the neighbors are in the same situation as if they had moved near a commercial site that had large trucks coming and going and the neigbors got together to shut down the commercial site. For comparison, I did a quick search for comparable studies on ultrafine particle emissions near major roads. I only picked out just one that seemed comparable (also LA area): http://sunscreamer.com/publiccomment...9%20405Fwy.pdf Figure 4(c) (90 m downwind) and 4(f) (300 m upwind) seem to indicate that an exposure factor about 17 times greater than background (comparing the peaks in fig 4(c) and 4(f) and dividing: 1.0E5 / 6.0E3) Comparable to the airport study finding a factor of about 10 for about the same distance from the source. As far as I can tell, the numbers seem to indicate that living near a busy airport is about as dangerous as living near a major highway with respect to ultrafine particle emissions. It seems that demanding that aircraft takeoffs be reduced or shut down entirely at an airport would be equivalent to demanding that the number of vehicles on a major highway be reduced or shut down. The options to neighbors appears to be roughly the same in both cases. |
