What are the health hazards of phosphorus pentachloride to humans?

Under normal circumstances, phosphorus pentachloride is an inorganic compound that poses significant hazards to human health, including poisoning, nervous system damage, and respiratory system injury.

1. Poisoning

Phosphorus pentachloride can enter the body through skin absorption, ingestion, or inhalation, leading to poisoning. Symptoms of poisoning include headache, dizziness, nausea, vomiting, diarrhea, chest tightness, difficulty breathing, convulsions, and coma.

2. Nervous System Damage

Phosphorus pentachloride can inhibit the activity of acetylcholinesterase, causing the neurotransmitter acetylcholine to accumulate at nerve endings and resulting in nervous system damage. Individuals with long-term exposure may experience symptoms such as neurasthenia, insomnia, depression, and anxiety.

3. Respiratory System Damage

Phosphorus pentachloride can irritate the respiratory tract, causing symptoms such as sore throat, coughing, and wheezing. Long-term exposure may lead to chronic respiratory diseases such as bronchitis and emphysema.

In addition, phosphorus pentachloride can cause gastrointestinal symptoms such as abdominal pain, diarrhea, nausea, and vomiting. Prolonged exposure may result in digestive system disorders such as gastritis and gastric ulcers. It can also cause skin irritation, itching, and redness. Individuals with extended contact may develop skin conditions such as allergic dermatitis and eczema. Therefore, phosphorus pentachloride is a highly hazardous chemical substance, and exposure or use should be avoided. In case of accidental exposure or poisoning, immediate medical attention is required.
