The Impact of Exposure and Toxicity Data on Drinking Water Standards for Boron

Price: £20  

This report discusses the potential toxicity of boron in relation to exposure via drinking water and the incorporation of the WHO guideline value into standards suitable for drinking water in Europe. Boron is a metalloid widely distributed in the environment and released into surface waters from industrial and domestic effluents. It is an essential micronutrient for the healthy growth of plants and therefore the greatest exposure source for humans is from fruit and vegetables. The EC average dietary intake of boron is in the range 1.64 - 4.54 mg/ day. Studies into the health effects of boron in humans have shown that it does not cause cancer but it has other adverse effects, principally testicular atrophy and possible developmental effects in the foetus. Based on recent exposure data, the report suggests that an allocation of 15 - 20% of the tolerable daily intake used to calculate the WHO guideline value and USEPA (199) health advisory value, to drinking water, could be considered suitable for the assessmen
