Dow AgroSciences generates methanol and uses xylene, both hazardous air pollutants, in making pesticide active ingredients at the plant.

Short-term exposure to methanol may result in blurry or dim vision as well as damage to the nervous system. Long-term exposure may result in headache, giddiness, insomnia, gastric disturbances, visual disturbances and blindness.

Long-term inhalation of xylene can cause headache, dizziness, fatigue, tremors and lack of coordination. Short-term inhalation can irritate the nose and throat and cause nausea, vomiting and gastric irritation.
