Article The nitrate content of fresh and cooked

DOCUMENT DESCRIPTION

Background
Vegetables are the most important source of nitrates in the human diet. During various processes in the body, nitrates are converted into nitrites, which causes various diseases, such
as blue baby syndrome and cancer. This study aimed to determine the concentration of
nitrates in several vegetable farms in Sanandaj city and to evaluate their health-related
risks.
Methods
This descriptive cross-sectional study was conducted from October 2017 to July 2018. A
total of 90 samples were taken from nine farms. Soil and water sampling was also carried
