Description

Zinc belongs to the homogeneous transition metal compounds, a class of homogeneous metal compounds within the inorganic compounds. It is an endogenous solid with the formula Zn and an average molecular weight of 65.41 g/mol. Biologically, zinc acts as a human metabolite, cofactor (PMC9774004), inhibitor (PMC5946256), and micronutrient (PMC10603774, PMC9314993, PMC9399584, PMC10302055, PMC7930903). It serves as a cofactor for 125 proteins, including the Beta-2 adrenergic receptor (ADRB2), Programmed cell death protein 6 (PDCD6), Amyloid-beta precursor protein (APP), and Aspartoacylase (ASPA), as well as Superoxide dismutase [Cu-Zn] (SOD1). Unbalanced levels of copper and zinc binding to SOD1 have been linked to amyotrophic lateral sclerosis (ALS). Industrially, zinc is used as an antioxidant (PMC8795399), Lewis acid (PMC5666261, PMC9082580, PMC8402239), pigment, plating agent, corrosion inhibitor, filler (PMC12076081), additive (PMC12489450, PMC13378312), and fertilizer (PMC6093934). It is also utilized as a surface modifier and processing aid. Environmentally, it is categorized as a nutrient (PMC8053940) and a heavy metal (PMC10404191). Zinc is found in various sources, including electrical equipment, household cleaning products, building materials, and food contact materials; it is present in Polyamide and Polycarbonate and released in Polypropylene, Polystyrene, Polyvinyl Chloride, and Polyethylene Terephthalate. Exposure routes include inhalation (PMC11791132, PMC5615498), smoking (PMC12961903), intravenous, oral, topical, and touch. Health effects include associations with cancer (PMC12351994, PMC8475335, PMC8986829), anemia (PMC10813191, PMC9566368), and inflammation (PMC13369252, PMC5739140, PMC9319427). It is linked to vomiting (PMC10721053, PMC12284794, PMC4624377, PMC9475415), nausea (PMC13193546, PMC9566368, PMC11625160, PMC3693117, PMC4624377, PMC8398132, PMC9475415), and abdominal pain (PMC10721053, PMC12284794). Zinc acts as a biomarker for male infertility (PMC9988266), though it is also used as a treatment for male infertility (PMC8523395, PMC9005387, PMC9988266) and COVID-19 (PMC9319427). It has therapeutic effects on blood pressure (PMC2905473) and bronchopulmonary dysplasia (PMC4670692).

Toxicity Profile

Mechanism of Toxicity

Excessive zinc intake alters copper and iron absorption, most likely through competitive binding in intestinal mucosal cells. Stomach acid dissolves metallic zinc, producing zinc chloride, which is a corrosive product damaging the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc. (2, 3, 1)

Carcinogenicity (IARC Classification)

No indication of carcinogenicity to humans (not listed by IARC).

Minimum Risk Level

Intermediate Oral: 0.3 mg/kg/day (5) Chronic Oral: 0.3 mg/kg/day (5)

Symptoms

Ingestion of large doses of zinc causes stomach cramps, nausea, and vomiting. Acute inhalation of large amounts of zinc causes metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Dermal contact with zinc results in skin irritation. (3)

Treatment

Zinc poisoning is treated symptomatically, often by administering fluids such as water or milk, or with gastric lavage. (3)
