The National Nutrition Conference on Defense, which was recently held In Wash ington, 0. C., included two sessions presented by the Section on Nutrition in . Industry. The effects of malnutrition on working efficiency, also measures for improving the diet and nutrition of workers were discussed. Beoent dietary studies among large representative samples of the people of the (Jnited States, clinical studies among smaller groups, and the examination of men called up, for military service show clearly that poor diets and undernourishment are wide spread in tho country. While there is no ground for alarmist statements, the facts are serious enough to be a genuine cause of weakness in the present nstio al emergency and to warrant national attention and concerted action. Uhdarnourlshment la more insidious and less obvious in its effects than a disease epidemic, but it is not loss harmful. Becomaendatloas made to the Conference hy this Section included: (l) special attention should be paid to the diet of all workers and particularly to the diet at defense workers, and (8) the cooper atlon of each State should be enlisted by urging the governor to call a State wide nutritional conference. The efforts should include an educational cam paign, and provision for restaurant and lunch facilities in factories.

There is a tendency during the warm simmer months to open windows in an attempt to obtain better ventilation. In many factories aid workshops there are oec patlonal health hazards effectively controlled by means of local exhaust system whose exact balance may be upset by stray air currents. In this way, toxic materials may be swept into the general ataosphsro end endanger the health at the workers. Under normal zoom air conditions processes, such as acid dip ping, alkali cleaning, electroplating, lacquer dipping, lead hardening, spray painting, or vapor degreasing by swans of chlorinated hydrocarbons, may be opei ated with the health hazards fully under control, but a breoso or draft from as open window may offset, to a major extent, the mechanical moans provided to guard against dissemination of toxic materials. It often happens that the - disahargeof a local exhaust system is relatively near a window so that whan opened, toxic materials may be returned to the workroom. This is particularly true when tho discharge is opposed to the prevailing simmer wind. During wain weather, it is essential for comfort, unless air conditioning is provided, that many windows bo oponod. However, Caro must be taken to eliminate drafts in the vicinity of -processes involving the use of toxic materials, through ths erection of suitable baffles or ths locking of occasional windows thereby assuring tho effective operation of existing control measures.
