Melamine is used in the synthesis of resins used for the manufacture of laminates, plastics and coatings, including materials in contact with food such as crockery. A method for the assessment of melamine by GC-MSMS in urine samples was developed and tested in 100 non-occupationally exposed subjects: 63 females (14 -66) and 37 males (15-65). The LOD and LOQ were 4 µg/l and 13.4 µg/l respectively. Results showed traces of melamine in the urines of 21% of subjects monitored (10 - 29.7µg / l). Presence of melamine and time since last meal at sampling were inversely related (p = 0.021). In addition a significant correlation (p = 0.00) between the presence of the substance in urines and the use of melamine dishes was shown.

Abstract
Melamine is used in the synthesis of resins used for the manufacture of laminates, plastics and coatings, including materials in contact with food such as crockery. A method for the assessment of melamine by GC-MSMS in urine samples was developed and tested in 100 non-occupationally exposed subjects: 63 females (14 -66) and 37 males (15-65). The LOD and LOQ were 4 µg/l and 13.4 µg/l respectively. Results showed traces of melamine in the urines of 21% of subjects monitored (10 - 29.7µg / l). Presence of melamine and time since last meal at sampling were inversely related (p = 0.021). In addition a significant correlation (p = 0.00) between the presence of the substance in urines and the use of melamine dishes was shown.
