Abstract |
For the establishment of reliable TLVs the authors recommend epidemiologic studies followed by statistical evaluation of the data obtained on the health damage sustained by exposed workers. They present the results of dynamic health status case studies in 651 workers exposed to dibutyl phthalate in producing PVC-base films. An early sign of sensorial disturbances is the lowering of the pain sensitivity threshold; the frequency of this phenomenon depends on the number of years of employment and the concentrations of dibutyl phthalate. A regressive linear equation is presented, enabling a TLV to be established with sufficient empirical precision. |
