Objectives: Few adults participate in enough physical activity for health benefits. The workplace provides a unique environment to deliver heath interventions and can be beneficial to the employee and the employer. The purpose of the study was to explore the use of a physical activity counseling (PAC) program and a fitness-based health risk assessment (fHRA) in the hospital workplace. Methods: A workplace-based intervention was developed utilizing a PAC program and an fHRA to improve physical activity levels of employees. Hospital employees were enrolled in a 4-month PAC program and given the option to also enroll in an fHRA program (PAC + fHRA). Physical activity was assessed by accelerometry and measured at baseline, 2 months, and 4 months. Changes in musculoskeletal fitness for those in the fHRA program were assessed at baseline and 2 months. Results: For both groups (PAC n = 22; PAC + fHRA n = 16), total and moderate to vigorous physical activity in bouts of 10 minutes or more increased significantly by 18.8 ( P = .004) and 10.2 ( P = .048) minutes per week at each data collection point, respectively. Only participants with gym memberships demonstrated increases in light physical activity over time. Those in the fHRA group significantly increased their overall musculoskeletal fitness levels from baseline levels (18.2 vs 21.7, P < .001). There was no difference in the change in physical activity levels between the groups. Conclusions: A PAC program in the workplace may increase physical activity levels within 4 months. The addition of an fHRA does not appear to further increase physical activity levels; however, it may improve overall employee musculoskeletal fitness levels.

BACKGROUND: University laboratory is an important place to carry out scientific research and related teaching activities, but the environmental pollution caused by waste discharge cannot be ignored. OBJECTIVE: The research aims to explore the environmental pollution caused by the waste of chemical laboratory, and the direct or indirect harm to human health. METHODS: The main pollutants discharged by the laboratories are counted through the analysis of the waste treatment status of university chemical laboratory. Then, the harm of the discharged pollutants to the environment is analyzed by experiments to find out the main pollution problem of the chemical laboratory - wastewater pollution. The groundwater pollution caused by laboratory wastewater discharge is analyzed, and the human health risk caused by it is evaluated. RESULTS: The results show that the discharge of chemical laboratory waste in colleges and universities will cause harm to human health. The results of health risk assessment show that benzene, trichloromethane, and dichloromethane are the main pollutants, and the use of chemical reagents is one of the important reasons for the surge of laboratory waste in colleges and universities; in the carcinogenesis of multi pollutants, compared with skin absorption, the risk of cancer caused by drinking water absorption was higher, and the corresponding risk value is 5.56e-07. CONCLUSIONS: The discharge of university chemical laboratory waste will cause harm to human health. This exploration provides reference for the study of environmental pollution and health risk assessment caused by waste discharge of university chemical laboratory.
