Smelling too much sulfuric acid may lead to dental corrosion, respiratory tract damage, digestive tract damage and other adverse phenomena. 1. Tooth corrosion: Because sulfuric acid gas has a strong corrosive effect, so the body of sulfuric acid sniffing too much, sulfuric acid gas in the material may be attached to the teeth, resulting in tooth corrosion. 2. Respiratory tract damage: after smelling too much sulfuric acid gas, sulfuric acid may be deposited on the mucous membrane wall of the respiratory tract, resulting in congestion, edema and other damage to the respiratory tract mucosa. 3. Digestive tract damage: Inhaling too much sulfuric acid gas can flow through the mouth to the digestive tract, thus causing damage to the digestive tract. Because when the human body smells too much sulfuric acid gas, it will have adverse effects on the human body, so it is recommended that when exposed to sulfuric acid gas, take protective measures, and seek medical attention in case of discomfort.
