Abstract

Owing to rapid population growth and industrialization, the situation of air pollution has become a public health
threat of global concern. White blood cells, also known as leukocytes or leucocytes, are immune system cells that
assist in defending the body against infectious diseases and foreign intruders. White blood cells are a component of
the immunological system of the body. They support the body's defense mechanisms against illness and infection.
Infection or inflammation are the usual causes of an overabundance of white blood cells. A high white blood cell
count may, less frequently, be a sign of some blood malignancies or bone marrow issues. Although immune system
inflammatory reactions might be linked with alterations in white blood cell counts in the body, there is the need to
provide more consistent reporting on the association between air pollution and varying white blood cell counts in the
body
