[Hygienic assessment of drinking water chlorination by-products in view of multiroute exposure].

On the example of threstationary sampling points in houses of the Western Administrative District data on presence of trihalomethanes (TGM)--the main by-products of chlorination--in cold drinking and hot tap water of Moscow were analyzed. Since 'tthe middle of 2007 the concentration of chloroform and other TGM in tests of tap water were established to be defined at levels steadily below hygienic maximum concentration limits. In the performed experiments it is revealed that, despite rather low content of chloroform in water, when using a hot shower considerable receipt of substance in air of the bathing room--in the concentration exceeding average daily maximum concentration limit in atmospheric air is possible. In calculations by the three methods of chloroform doses which can influence the person in living conditions, inhalation receipt was shown to be less if compared with an peroral way (with drinking water) and absorption through skin appear and can make the greatest contribution to the general complex loading of chloroform.
