| Their activity may be enhanced by using membrane-disrupting surfactants such as quaternary ammonium compounds. |
| These include things such as urea, ammonia, nitric acid, and ammonium phosphate. |
| A major national supplier announced it would stop selling ammonium nitrate as its easy accessibility questioned local safety. |
