Ammonia-NH3 Sensors Used in Animal Husbandry Farm
Texas dairy explosion leaves at least 18,000 cattle dead, 1 person critically injured(News Source：Foxnews)
The Castro County Sheriff’s Office confirmed with Fox News Digital that the cows were in a holding area before being brought in for milking when the blast occurred at the Southfork Dairy Farm in Dimmitt.
Very few cows in the holding area survived, officials told local outlet KFDA.
Smoke is visible a day after a massive explosion at a Texas dairy farm that left one person critically injured and 18,000 cattle dead. (Castro County Sheriff's Office)The waste of farm animals not only has adverse effects on livestock and poultry itself, but also poses a serious threat to the surrounding environment. Livestock and poultry farming is a major emitter of ammonia gas, and after the ammonia gas reacts with the oxidation products of sulfur dioxide and nitrogen oxides, it will produce ammonium nitrate and ammonium sulfate, which are important sources of toxic particulate matters.
Ammonia gas is often adsorbed or dissolved on wet walls and floors, which is highly irritating and corrosive to the mucous membranes and skin of livestock and poultry. After ammonia enters the blood, it reduces the amount of dissolved oxygen in the blood and reduces the resistance of livestock and poultry. Long-term exposure to ammonia concentrations of 10-15 mg/kg will significantly reduce the stress resistance of animals. In addition, Ammonia (NH3) is a colorless gas with a strong, noticeable smell; the harmful and poisonous air inhale can also harm the human and induce various diseases.
Establishing scientific detection, monitoring and processing system for ammonia in livestock and poultry houses provides important technical support for energy saving, pollution emission and efficient production.
