Functions of water in the body.

SYMPOSIUM PROCEEDINGS I957 no occasion for apprehension. We are not the sole occupiers of the world, however, and I am informed that every time an atom bomb or hydrogen bomb is exploded the radioactivity of natural waters is raised inevitably throughout the world-the effect is by no means a localized one. The consequences remain to be seen, and I hazard no guess as to what they are likely to be. Superficial though my remarks have been, I hope I may have succeeded in conveying the impression that, in the modern state, the problem of water supply is a general one. Man’s personal need cannot be disassociated from the need of industry and these have to be made compatible. Conditions are such that water must be reused, often many times, if it is to be available in sufficient quantity. The avoidance of unnecessary pollution from both domestic and industrial sources should be the aim of every one of us in helping those whose business it is to ensure that the quality is of the required standard.
