What are we breathing now? Let me guess...

There may be a partial answer at a newly created section of the EPA website. It lists all admitted toxic emissions from factories, government operations and other facilities around the U.S. Here's where you can go search your own zip code, or the one for your kid's school.

One warning, this information is largely based on annual reports filed by the management of whatever facility is involved. So it may be about as dependable as the quarterly earnings report of, say, Bear Stearns or Fannie Mae. It is enlightening to check on what's said to be coming out of those nearby factories.

My current and former Zip Codes included primarily residential properties, and nobody monitors the horrid grease coming out of the local fast food joints. Searches on those zips turned up zilch.

So I checked on the small town where I spent four years in college. Here's what the town's one electronics firm admits to: MULTEK FLEXIBLE CIRCUITS INC, 1150 SHELDAHL RD, NORTHFIELD: AMMONIA ANTIMONY COMPOUNDS COPPER COMPOUNDS DECABROMODIPHENYL OXIDE LEAD COMPOUNDS METHANOL NITRATE COMPOUNDS NITRIC ACID TOLUENE

I think we may have new sort of trivia game. You list the toxics and the winner has to guess the zip code or county from which it is emitted. You get half credit if you guess only the state.

Here's a formidable list, for example, that would have contestants guessing a toxic waste dump in Nevada. No, it's simply the oil refinery nearest to Silicon Valley where many VCs and tech firms are coagulated.

CHEVRON PRODUCTS CO. RICHMOND REFINERY, 841 CHEVRON WAY, RICHMOND 94802 1,2,4-TRIMETHYLBENZENE 1,2-DIBROMOETHANE 1,3-BUTADIENE AMMONIA BENZENE BENZO(G,H,I)PERYLENE CHROMIUM COMPOUNDS(EXCEPT CHROMITE ORE MINED IN THE TRANSVAAL REGION) COPPER COMPOUNDS CRESOL (MIXED ISOMERS) CYCLOHEXANE DIETHANOLAMINE ETHYLBENZENE ETHYLENE HYDROCHLORIC ACID (1995 AND AFTER "ACID AEROSOLS" ONLY) LEAD COMPOUNDS MERCURY COMPOUNDS METHANOL MOLYBDENUM TRIOXIDE N-HEXANE NAPHTHALENE NICKEL COMPOUNDS NITRATE COMPOUNDS PHENOL POLYCYCLIC AROMATIC COMPOUNDS PROPYLENE TETRACHLOROETHYLENE TOLUENE VANADIUM COMPOUNDS XYLENE (MIXED ISOMERS) ZINC COMPOUNDS

Breath deeply. Enjoy the website.
