ABSTRACT

<p><b>OBJECTIVE</b>To find out the relationship between the opacity in lens and the contents of 2,6-dinitro-4-amino-toluene(DNAT) in the urine of exposed workers.</p><p><b>METHODS</b>Testing the exposed worker's lens and measuring the contents of DNAT in the urine after work.</p><p><b>RESULTS</b>When the opacity of the lens occurred, the contents of DNAT in the urine(2.38 mg/L) of workers exposed to TNT were significantly higher than those without opacity in lens(1.44 mg/L) (P < 0.05).</p><p><b>CONCLUSION</b>The severity of opacity of lens increased with the contents of DNAT raised in the urine. The threshold value suggested by ILO is not applicable to Chinese occupational population, which recommends the contents of DNAT(30 mg/L) in the urine for the workers exposed to TNT as biological occupational exposed limits.</p>
