    Question

    Which element irritates the mucous membrane?

    1. Cl
    2. F
    3. Br
    4. Na

    Hint:

    Cl has the atomic number 17.

    The correct answer is: Cl

      In addition to hypersensitivity and transient bronchospasm, chlorine gas inhalation can cause temporary irritation of the mucous membranes and pulmonary edema due to increased vascular permeability, resulting in eosinophils, and neutrophils It allows the influx of lymphocytes into the lungs, causing an increase in pneumonia.
