Diesel engines emit a mixture of air pollutants, which are composed of gaseous and solid material. The visible emissions in diesel exhaust are known as particulate matter and includes carbon particles or "soot." Diesel exhaust also contains a variety of harmful gases and over 40 other cancer-causing substances. In 1998, California identified diesel PM as a toxic air contaminant based on its potential to cause cancer, premature death, and other health problems. In addition, diesel soot causes visibility reduction and is a potent global warmer.
