Extra studies show each of two first factors is in hazard zone in %6.67 of jobs. Combined data show most of studied jobs have more than one factor at unacceptable level. Environmental and occupational risk factors are low regard to amount but considering %93.33 of studied jobs contains one risk factor at least so, it is likely to increase in problems.
