Association of Nitrate, Nitrite, and Total Organic Carbon (TOC) in Drinking Water and Gastrointestinal Disease
OBJECTIVE We aimed to investigate the amounts of nitrate, nitrite, and total organic carbon (TOC) in two drinking water sources and their relationship with some gastrointestinal diseases. METHODS This cross-sectional study was conducted in 2012 in Iran. Two wells located in residential areas were selected for sampling and measuring the TOC, nitrate (NO3(-)), and nitrite (NO2(-)). This water i...

Background & Aims: Esophageal and gastric cancers are among prevalent cancers in the world and it is believed that nitrate and nitrite contaminations of drinking water are important factors in increasing the risk of these cancers. This study was designed to determine the correlations between these factors and upper gastrointestinal cancers. Methods: In this ecologic study, mean concentrations o...
متن کاملNitrate, Nitrite, and Ammonium Variability in Drinking Water Distribution Systems
Accurate assessments of exposure to nitrate in drinking water is a crucial part of epidemiological studies investigating long-term adverse human health effects. However, since drinking water nitrate measurements are usually collected for regulatory purposes, assumptions on (1) the intra-distribution system variability and (2) short-term (seasonal) concentration variability have to be made. We a...
