One of the pollutants leading to heavy metal pollution is the lead element. The studies on exposure of fish to lead have shown that this exposure leads to negative effects on body weight, and digestive enzymes and lipase. In humans, the symptoms of chronic lead toxicity are renal malfunction, anemia, brain and liver damage, cancer, hyperactivity, and general psychological impairment.

Zeolites are used in many fields such as agriculture, metal industry, energy sector, manufacturing industry, water treatment, animal husbandry, struggling with environmental pollution, and etc.
