[Upper respiratory tract function in workers in modern dye (cotton) manufacture]

Area of Science:

• Occupational Health
• Toxicology
• Environmental Medicine

Background:

• Cotton dye works utilize novel active vinylsulfone dyes.
• Occupational exposure to chemical agents can impact respiratory health.

Purpose of the Study:

• To assess the clinical and functional effects of novel active vinylsulfone dyes on the upper respiratory tracts (URT) of cotton dye workers.
• To determine the prevalence and severity of URT affections in relation to dye exposure.

Main Methods:

• Clinical and functional examination of the upper respiratory tracts.
• Comparative analysis between dye-exposed employees and a non-exposed group.
• Assessment of lesion severity based on occupation and length of service.

Main Results:

• Employees exposed to active dyes showed affections of the URT mucosa.
• Chronic subatrophic and catarrhal rhinopharyngitis occurred 3 times more frequently in dye-exposed subjects.
• Early harmful effects of dye aerosols on the URT were evidenced in the majority of examinees.

Conclusions:

• Occupational exposure to active vinylsulfone dyes poses a significant risk to the upper respiratory tract.
• The findings highlight the need for protective measures in cotton dye works to mitigate URT health issues.
