They speculate that the odor came from a truck transporting the chemical Mercapton, which odorizes natural gas to warn people of its presence. Gas in its natural form is odorless...
RADIOACTIVE CONTAMINATION: There are no rules about how much is safe, but the N.R.D.C. cites EPA figures showing that about 50 million Americans drink radon-tainted water. The tasteless, odorless gas, which seeps into water naturally from underground rocks in many areas, is a proven cause of both lung and rectal cancer...
Audubon's chief scientist, Jan Beyea, was in on all these decisions. Even so, he was stunned by one result of the effort: an odorless building. "A month before we moved in, I'm walking around, and they are painting the walls and laying down the rugs and I can't smell anything," Beyea recalls. "That shows we did our job." Beyea attributes the facility's overall success to "a hundred, maybe several hundred, different little things, each of which by itself is rather insignificant...
...years the Environmental Protection Agency has urged Americans to check their homes for radon contamination. Seeping into basements from underlying rocks and soil, the colorless, odorless radioactive gas raises the risk of lung cancer. The EPA maintains that a household level of four picocuries of radiation per liter of air is enough to produce cancer in 13 to 50 of every 1,000 people who breathe it regularly.

...common cooking oils, canola contains the lowest level of saturated fat -- the kind that boosts blood cholesterol, the villain in many forms of heart disease. Like other oils, canola boasts a long shelf life, has the ability to remain odorless at high frying temperatures and averages 120 calories per tablespoon. But canola's biggest attraction is its scant, 6% level of saturated fat, in contrast to 14% in olive oil and 51% in palm oil. Canola also contains high levels of monounsaturated fat. For a number of years, consuming that substance was thought to reduce the "bad" type of cholesterol...
