Background: Trinitrotoluene (TNT) is an explosive which is widely used
in the defense industry, primarily in manufacturing ammunition. It can
cause various damages to the organs in the body such as the liver, blood
and blood – forming organs, eyes, nervous systemand organs for sexual
function of men.
Objectives: The study was conducted to assess the Trinitrotoluene (TNT)
pollution status in working environment and health - related influences
of workers at some Southern national defensive units of munitions
manufacturing, testing, repairing and preserving between 2010 and 2012,
including K1, K8, T2 and Zx.
Methods: A cross - sectional study with retrospective data.
Result: TNT concentrations in the working environment were from 0.027 to
1.145 mg/m3 of air. TNT concentrations in the manufacturing area of the
shells were 14 times higher than the permitted standard. Workers
exposed to TNT polluted environment for a long time had impaired health.
Chronic diseases such as anemia, neurasthenia and gastro - duodenal
made up 16 - 18%. 41.54% of male workers occupationally exposed to TNT
had decreased libido. The percentage of erectile dysfunction and
premature ejaculation were 10.77% and 7.69% respectively. The percentage
of people occupationally exposed to TNT had SGOT and SGPT indicators
which were higher than the normal physiological value was 15.79%.
Conclusion: Workplace environmentat some military explosive material
factories were seriously polluted by TNT exploxives. Measures to improve
sanitary conditions in working environment to reduce TNT pollution
levels need to be accounted.
Key words: Trinitrotoluene (TNT)
