But, some of them are released in the air (trichloramine) and makes the area around the swimming pool will smell such chlorine.
The highest concentration of chloramines in the air in the shortest distance, that is on the surface of the pool.
For the sake of the clean of water that will be got, the manger of the swimming pool will add the amount of chlorine that is used in the water.
However, the high concentration of chlorine causes the body absorbs the danger substance, especially for the skin and the respiratory.
