Seven Cases of Respiratory Symptoms Caused by Acute Ozone Exposure from an Electronics Company: Yong Jun Kwon, Kuck Hyun Woo, Jin Seok Kim, Seong Yong Yoon, In Ung Song, Jay Young Yu, Seong Yong Cho; Korean Journal of Occupational and Environmental Medicine 2012;24(4):449-459.

BACKGROUND
Ozone is a colorless, pungent, and highly reactive gas. It can cause headaches, burning eyes, irritation to the respiratory passages, and dyspnea. This article describes cases of respiratory difficulty associated with acute ozone exposure from an electronics company that manufactures touchscreen.
CASE
REPORT: Seven young female workers visited the Department of Occupational and Environmental Medicine, complaining of cough, dyspnea, and chest discomfort that started within two days at work processing a touchscreen with ozone (0.103 ppm ozone detected in the their workplace). Other; symptoms observed included rhinorrhea, headaches, and dizziness. There was a temporary improvement in symptoms upon taking a day off, but their symptoms deteriorated upon continuing work again-suggesting the ozone exposure in their work environment was responsible for their symptoms. The results of pulmonary function and blood laboratory tests were normal; however, laryngoscopy and nasal endoscopy identified three cases of inflammation on laryngeal, intranasal, or vocal cord regions.
CONCLUSIONS
Based on the levels of ozone detected in the workplace and clinical symptoms presented, we conclude that the respiratory symptoms in these cases were caused by excessive ozone exposures.

Abstract PDF

OBJECTIVES
The purpose of this study was to develop a program applying participatory action-oriented training (PAOT) methods for the management of cardiovascular disease risk factors and to assess its effectiveness in the workplace.
METHODS
The cardiovascular disease risk factors of 817 workers in the workplace were assessed, and periodic health examination was conducted. Sixty-four workers (7.8%) were selected as a moderate-risk group and high risk group, and performed the participatory approach program for cardiovascular disease preventive management.
RESULTS
The sixty-four workers who participated in the participatory approach program made a total of 246 action plans, 3.8 action plans per person and 115 action plans were achieved after three months, so that 46.7% of action plans have been achieved. In the intervention group that participated in the program, the rate of smoking decreased from 36.2% to 8.6% and systolic and diastolic blood pressure significantly decreased from 140.0+/-9.4 mmHg to 134.2+/-12.3 mmHg and from 92.6+/-7.1 mmHg to 80.0+/-9.8 mmHg respectfully. In addition, risk factor score also decreased by 0.3, whereas the control group who did not participate in the program also showed a significant reduction in the mean systolic and diastolic blood pressure. Regular exercise increased from 8.5% to 16.0%.
CONCLUSIONS
To improve the effectiveness of the participatory approach program for the management of cardiovascular disease risk factors, the need to continues implementing programs and analysis of the long-term effects are required.
