Section 2: Health hazards associated with 4-Amino-3(2H)-pyridazinone

2.
1 Skin irritation and allergy:

Exposure to APP may cause skin irritation, including redness, itching, and blistering.
In some cases, it can also cause allergic reactions, including dermatitis and allergic contact dermatitis.
Prolonged exposure to APP may cause skin sensitization, which can lead to an increased risk of allergic reactions with subsequent exposures.

2.
2 Respiratory hazards:

Ingestion of APP can cause respiratory irritation, including coughing, choking, and difficulty breathing.
Prolonged exposure to high concentrations of APP may cause more severe respiratory problems, such as pulmonary edema and respiratory failure.

2.
3 Aspiration hazards:

Because APP is highly soluble in water, it can pose a hazard if ingested or inhaled.
Ingestion of APP can cause gastrointestinal irritation, including nausea, vomiting, and diarrhea.
Inhalation of APP can cause respiratory irritation and aspiration pneumonia.

2.
4 Cancer risks:

There is limited evidence available regarding the carcinogenicity of APP.
Some studies have suggested that prolonged exposure to high concentrations of APP may increase the risk of cancer, particularly in the respiratory and digestive systems.
However, more research is needed to confirm these findings.
