Toxicity associated with long term use of aluminum cookware in mice: A systemic, genetic and reproductive perspective

Area of Science:

• Environmental Toxicology
• Genetics
• Materials Science

Background:

• Limited research exists on the toxic effects of cooking with aluminum pots.
• Previous studies have not investigated the impact of aluminum cookware on genetic material in germ and somatic cells.

Purpose of the Study:

• To investigate the cytogenotoxic effects of boiled water from aluminum pots of varying ages.
• To assess the impact on germ and somatic cells using mouse sperm morphology and bone marrow micronucleus tests.

Main Methods:

• Mice were exposed to boiled water from new, 3-year, and 6-year-old aluminum pots for 3-5 weeks.
• Heavy metal analysis of boiled water was conducted.
• Sperm morphology, sperm count, and bone marrow micronucleus tests were performed.
• Serum enzyme activities (AST, ALT) and liver oxidative stress markers (MDA, SOD, CAT) were analyzed.

Main Results:

• Boiled water contained heavy metals (As, Pb, Cd, Al), with higher concentrations in older pots.
• Significant increases in abnormal sperm cells and decreases in sperm count were observed with exposure duration and pot age.
• Increased micronucleated polychromatic erythrocytes and nuclear abnormalities were found, correlating with pot age.
• Elevated serum AST/ALT and liver MDA/SOD/CAT levels indicated cellular damage and oxidative stress.

Conclusions:

• Boiled water from aluminum pots exhibits cytotoxic and genotoxic potential.
• The aging of aluminum cookware exacerbates these harmful effects.
• Findings suggest potential health risks associated with prolonged use of aluminum pots.
