Allergy and Dermatitis Associated with Domestic Water Supplies
ISBN: 1 84057 005 9
In recent years there has been an increase in the number of consumers reporting apparent allergic or irritant reactions due to contact with drinking water. This report assesses the relative ability of potential drinking water constituents and contaminants to cause such reactions. A review was conducted based on reports in the literature and on enquiries to the toxicology enquiry service over the past ten years. The report concludes that drinking water is a minor source of contaminants which could cause contact dermatitis compared with other sources such as occupational exposure and food. However, there may be a slight increased risk for a small percentage of the population who are already sensitised to particular substances. In addition, there exists a condition called aquagenic pruritus in which itching can be caused by contact with water without exhibiting observable skin changes.
