Chlorine
Chlorine is a known toxin that can severely damage the respiratory system if inhaled by humans. Chlorine is heavier than air, so it often settles at ground-level in spaces that are not adequately ventilated.
When inhaled, chlorine can cause vomiting, breathing difficulties, and chest pain, and may be fatal in large amounts. Exposure to chlorine gas can damage the eyes and cause severe eye pain.
If mixed with certain other chemicals, including ammonium phosphate, explosions can occur. Chlorine is released by oil refineries in large amounts and poses one of the greatest threats because it is highly combustible and does not mix well with other refinery waste chemicals.
In addition to respiratory issues, chlorine exposure can also cause kidney, gastrointestinal and cardiovascular damage. Utah, Texas and Louisiana have the most chlorine pollution in the country, and ConocoPhillips is one of the largest producers of chlorine waste per year.
