Several substances are known to cause anemia, including:
Lead: Interferes with multiple enzymatic processes in hemoglobin synthesis, leading to microcytic anemia. Benzene: Affects the bone marrow, potentially causing aplastic anemia. Arsenic: Can lead to hemolytic anemia by inducing oxidative stress in red blood cells. Carbon monoxide: Binds with hemoglobin to form carboxyhemoglobin, reducing oxygen transport and causing functional anemia.
