To investigate the migration and correlation of melamine and formaldehyde from melamine tableware in China markets, and to provide the scientific basis for future risk assessment. Methods Migration of formaldehyde was analyzed by spectrophotometric and migration of melamine was analyzed by HPLC. Migration experimental conditions were 90degree for 30minutes, and the analog solvent was 3% acetic acid. [WT5"HZ]Results 41samples were collected from markets. Melamine was detected in 28samples and the maximum migration value was 0.85mg/dm². It was about 17.0% of SML regulated by EU. Formaldehyde was detected in all 41samples. The maximum migration value was 270.56mg/dm². It was about 108.2times SML regulated by EU. 53.66% of samples exceeded the SML value. Conclusion If melamine wasn’t detected but high amount of formaldehyde was detected, then the tableware might not be melamine tableware. The safety of melamine tableware is worthy of further attention.
