I am contacting experts because I am in a life-threatening situation. I am being targeted in a hostile work environment and I cannot identify the toxin. It is ordorless, has immediate effect through inhalation, causes cough, foamy sputum, bronchial involvement feels like a chest cold, lungs sometimes hyperinflated, muscle cramps or fatique, dry or achy eyes, sometimes causes heart and lung pain. Toxic agent dissipates after a few days. Sometimes seems to be activated by movement. Exposure has a limited range. What could this be??
