Objectives: To describe levels of nitrate and trace elements in drinking water from the study areas of a multicase-control study of cancer in Spain (MCC-Spain).
Methods: A total of 227 tap water samples were randomly collected from 67 municipalities in 11 provinces and the nine most frequently consumed bottled water brands were sampled to measure levels of nitrate, arsenic, nickel, chromium, cadmium, lead, selenium and zinc.
Results: The median nitrate level was 4.
Article Synopsis
- The study investigates the health risks of disinfection by-products (DBPs) in drinking water, focusing on a variety of chemical compounds and their concentrations in water samples from 11 Spanish provinces.
- A total of 233 tap water samples were collected in 2010, and the analysis highlighted specific levels of trihalomethanes (THMs) and haloacetic acids (HAAs), among other DBPs, revealing significant variations in concentration.
- By using principal component analysis, the research found that THMs and HAAs do not effectively predict the presence of other DBPs, emphasizing the need for advanced methods to understand these complex mixtures in water.
