Abstract: (12 Views)
Introduction: BTEX are chemical compounds with adverse effects on the nervous system and cognitive function. This study aimed at examining the effect of exposure to volatile organic components on selective attention in employees.
Method: 103 employees exposed to BTEX in a dye factory as the case group,95 employees not exposed to BTEX in textile factory as the control group.Data collection was done using a researcher-made demographic questionnaire.Sampling of BTEX was carried out using the standard method of 1501 NIOSH and personal sampling pump. To measure the selective attention, a complex cognitive Stroop Test Software was used.
Results: toluene in the mill and packaging of the dye factory was higher than the allowable limit. A significant difference was observed between mean reaction time of congruent words in the performance of the case group (133) 825.7 milliseconds and the control group (62.6) 789.7 milliseconds. There was no significant difference between the two groups in terms of mean reaction time of incongruent words (P-Value = 0.74). In subscales of correct responses, incorrect responses, no responses and interference score in the complex Stroop test, a significant difference was obtained between the two groups.
Conclusion: BTEX in long-term exposure can affect the selective attention.
