Chlorine dioxide is not stable and is rapidly decomposed by light. It also produces harmful byproducts, chlorate and chlorite. The UK limit is 0.5ppm for the sum total of chlorine dioxide, chlorite and chlorate but this limit is often exceeded as there is no simple test to evaluate the level. It is no use sending samples to a sophisticated laboratory as by the time the sample got there, it would no longer be representative
