Science to ban bad

Dear Editor:

Re: Sweetgrass burning ban

I was interested to read in your publication that the authorities in charge of Fort Saskatchewan Correctional Institution have apparently banned sweetgrass burning in smudging ceremonies, but continue to allow incense burning during Roman Catholic ceremonies in the correctional facility's chapel.

An article entitled "Particles in church air bad for lungs, study says" appeared in the Toronto Star on Nov. 23, 2004. This article refers to a study conducted by scientists from Maastricht University and published in the European Respiratory Journal.

According to the article: "The air at a Maastricht basilica contained 20 times the European Union limit of PM10 (Particulate Matter) particles after a simulated mass ceremony. Tiny PM10 particles can be inhaled and are a potential hazard. The scientists also found high levels of carcinogenic polycyclic aromatic hydrocarbons as well as some unknown types of free radicals released from burning candles and incense. Free radical atoms act as starters and promoters of cancer tumors."

It seems that the distinction between candle or incense burning during Roman Catholic ceremonies and sweetgrass burning during smudging ceremonies is not based on science. If correctional staff or inmates are concerned about potential health effects from the inhalation of burning sweetgrass, they should also be concerned about candle or incense burning.

Providing separate areas ventilated to the outside where anyone might practice their religious beliefs without affecting the air in the rest of the facility might be a compromise that could meet everyone's requirements.
