The protective external layer of skin may be softened (by toluene, dilute washing soda solution, etc) thus permitting other chemicals to enter readily to the bloodstream (such as aniline, phenol, benzene, etc). Eyes may also absorb chemical substances, either from splashes or from vapours. Dangerous chemicals can enter the body through ingestion as gases, dusts, vapours, fumes, liquids or.
And research suggests that disinfectants may pose their own health hazards. Swimming in chlorinated pools, particularly indoor pools, might put kids at higher risk for developing respiratory illnesses, including asthma and hay fever. In addition, there is evidence that disinfectant by-products--formed when chlorinated water is mixed with microorganisms, human body fluids, cosmetics, and.
