[Urea as an indicator of anthropogenic pollution of water of swimming pools].

The sports swimming pools of Volgograd were examined for the levels of urea. All the study swimming pools were found to have a level of urea in the range of 28-80 micromol/l; which is about 10-15 times higher that its background level in the natural water reservoirs. Analysis of urea in the water of a swimming pool is proposed as a sensitive and simple test for fresh man-made water pollution.
