Antimicrobial nitrates and nitrites, often found in cured meats, ward off the bacteria that cause botulism, but they may cause other health problems. Some studies linking cured meats to cancer have suggested that these preservatives may be the culprit.

American Writer
The usual way of growing cotton is highly petrochemical-intensive, requiring 110 pounds of nitrogen fertilizer per acre. Some of the fertilizer is broken down by soil bacteria into nitrate, a toxic and highly soluble chemical that can leach into groundwater or get washed into lakes, creating oxygenless dead zones.

For the life of me, I can't understand why BP couldn't go in at the ocean floor, maybe 10 feet lateral to the - around the periphery, drill a few holes, and put a little ammonium nitrate, some dynamite, in those holes and detonate that dynamite and seal that - seal that leak. And seal it permanently.

I'm sad to see celluloid go, there's no doubt. But, you know, nitrate went, by the way, in 1971. If you ever saw a nitrate print of a silent film and then saw an acetate print, you'd see a big difference, but nobody remembers anymore. The acetate print is what we have. Maybe. Now it's digital.

American Politician
If we don't preserve the oceans from nitrate runoff and plastic and chemicals, and if we don't preserve it from acidification, and if we don't preserve it from grotesque overfishing - too much money chasing too few fish - we're going to have the most massive ecosystem on the planet in peril.

In our experience, when people make comprehensive lifestyle changes, they usually can reduce or discontinue medications such as cholesterol-lowering drugs, anti-hypertensives, beta-blockers, ACE inhibitors, nitrates, insulin, and so on.

As far as plants are concerned, they can't tell whether that nitrate ion comes from artificial chemicals or from decomposed organic matter.

You can't ask your pharmacist to stock larger quantities of potassium nitrate because you want to make a bigger rocket.
