“…Furthermore, there was a significant moderate negative correlation between FEV1, and FVC with both work experience and cumulative VOC exposure index. Several epidemiological studies have reported similar findings [10,[21][22][23], however, few studies conducted among organized sectors like shipyard and automobile industries have shown no differences in the PFT parameters such as FEV1 and FVC among painters compared to that of the matched unexposed individual [24,25]. A few of the contributing factors that might reduce the pulmonary functions in these unorganized sectors are inadequate health awareness, lack of usage of PPE, and non-adherence to safety measures and protocols by the employees and the employers of these sectors [26].…”

BackgroundPaint industry workers are constantly exposed to paints and organic solvents that contain a substantial quantity of volatile organic compounds (VOCs). Exposure to VOC emissions could result in pulmonary, neurobehavioral, and hematological consequences. Limited studies have been undertaken in India to assess the health consequences of VOCs among paint industry workers in unorganized sectors. AimTo assess the effects of VOCs on pulmonary function in paint industry workers of unorganized sectors. MethodologyA hundred and twenty full-time male construction painters and small-scale paint manufacturing workers aged 25-60 were assessed for respiratory symptoms using a questionnaire, and pulmonary functions using Wright's Peak Expiratory Flow Meter (PEFR). Participants were randomly selected for VOC assessment and the cumulative solvent exposure index was calculated. A pulmonary function test (PFT) was performed on a subset of construction painters (n=30) using a Koko spirometer. ResultsThe concentration of VOCs such as benzene, ethylbenzene, toluene, and xylene (BETX) and dichloromethane levels exceeded American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit values (TLVs) among the paint manufacturing workers. About 52% of paint workers reported respiratory symptoms. Around 22% of the participants showed reduced pulmonary function (PEFR<400 L/min). There was a significant weak negative correlation between PEFR and work experience (r = -0.2, p=0.03). PFT parameters among a subset of construction painters revealed a significant moderate negative correlation with work experience [forced expiratory volume at the onset of the first second (FEV1) (r = -0.6, p=0.001) and forced vital capacity (FVC) (r = -0.53, p=0.005)] and cumulative VOC exposure index [FEV1 (r = -0.53, p = 0.004) and FVC (r = -0.5, p = 0.008)]. ConclusionThe concentration of VOCs was higher among paint industry workers of unorganized sectors and they reported respiratory symptoms and diminished pulmonary function. To reduce morbidity, it is critical to enhance awareness about occupational safety and services in these unorganized sectors.

“…Exposure to noise in the work environment is perhaps one of the most important reasons for hearing dysfunctions in employees of fabrication industries and others who work with noise producing machines. In case of paint and chemical industries wherein machines such as centrifuges and boilers are common for numerous chemical processes, aromatic chemicals/solvents too play an important role in the deterioration of hearing abilities of such employees [7]. There is adequate proof to prove that a combined effect of exposure to noise as well as solvents cause a higher degree of hearing loss in the employees of solvent industries with constant exposure.…”

This study presents a novel approach to assess the perception of auditory Absolute threshold (ATTh) in healthy individuals exposed to noise and solvents in their occupational environment using machine learning approaches. 396 subjects with no known history of auditory pathology were chosen from three groups, namely, employees from Chemical Industries (CI), Fabrication Industries (FI), and professional Basketball Players (BP), with each category having 132 subjects. Absolute Threshold Test (ATT) was developed using MATLAB and the experiment was conducted in a silent, noise-free environment. ATTh was obtained twice, during the commencement and conclusion of the employees' workshift in CI and FI. For BP, ATTh was obtained before and after their basketball training sessions and was used as features for binary SVM classification approach, in which the RBF kernel-based technique was found to provide maximum accuracy as compared to linear and quadratic approach. For three-class classification, MLP neural network with Levenberg-Marquardt training function in the hidden layer and Mean Square Error function in the output layer was found to be optimal along with k-Nearest Neighbor (kNN) and Support Vector Machine (SVM) approach using Radial Basis Kernel Function (RBF), in which, an accuracy of 81.06% was observed in kNN approach and 92.4% using MLP neural network approach, whereas SVM yielded an accuracy of 93.94% in the classification of the subjects into CI, FI and BP, showing that the SVM outperformed kNN and MLP neural network for healthy subjects based on their occupational exposure/professional sports training. Such machine learning approaches could further be probed into, to improve the accuracy of classification. Also, such techniques can help in real-time classification of subjects based on their occupational exposure so as to predict and prevent plausible permanent hearing dysfunction due to occupational exposure as well as to aid in sports rehabilitation and training programs to assess the auditory perceptive abilities of the individuals.
