Abstract
Samples of lettuce, carrot, cabbage, spi nach , and potato were collected in free markets of São Paulo City, Brazil. High levels of nitratos were consistently found in spinach samples and they ranged from 545 to 4136 mg per kg (mean: 2030 mg, and 90th percentile: 3306 mg/kg). Several samples of potatoes showed from O to 748 mg/kg. The samples of lettuce, carrot and cabbage showed considerable variation which ranged from no nitrates to very high values such as 5896 mg/kg found in one sample.
