[Hygienic evaluation of the combined effect of portable water chloroform].

The paper considers the significance of complex entrance of chloroform from portable water into the human body (enterally, inhalationally, and through the intact skin). It shows it necessary to toughen the maximum permissible concentration (MPC) of chloroform in the portable drinking, by taking into account of the multiplicity of routes of its action on the population. The authors present the results of their own investigations of the levels of chloroform in the air of bath and shower rooms before and after taking a shower and filling the bath with water, as well as in the airspace layer above the water of an indoor swimming pool, by using chromatographic mass-spectrometry.
