The lists of American, Russian and Chinese MACs and TLV for chemical hazards in the air of workplace were analyzed. Chinese MACs turned out to be similar to Russian ones, because the definition of MAC and the methodic approaches to the parameter are equivalent. American TLV are not identical to MAC, therefore their values are different. The examples of difference in hygienic standards for various chemicals are given.
