Future Plans

The SCERC plans to place an increased emphasis on Outreach in the coming years. There are several initiatives that will be implemented in achievable stages. Some of the initiatives wil include the participation of members of the SCERC Advisory Board and program advisory committees.

Follow-up Webinars

Academic programs will offer a webinar to program alumni and others to discuss workplace health and safety issues in the form of case studies that have arisen at their workplaces. Each webinar will be moderated by a faculty member or member of a SCERC advisory committee. The Industrial Hygiene program would take the lead on this activity because participants from medicine and nursing are constrained by HIPAA from discussing cases. This activity would benefit employers of the alumni by providing suggestions for improved practices, controls, etc.

Consultation Services

Programs will offer organizations and businesses in minority communities or with minority owners or leadership brief consultations on their IIPP or other workplace practices. Since this is a brief commitment, the topic would probably be limited to, e.g., is the ventilation system adequate, do they need a medical surveillance program, do they have slip, trip and fall hazards they may be aware of?

Members of the SCERC Advisory Board and committee members, most of whom are practicing professionals, would mentor the participating students, under faculty supervision. Second year students and PhD candidates, either individually or in interdisciplinary groups of two or three would spend part of a day at a business, write a report on their findings, discuss the report with the mentor and faculty supervisor and report back to the business on what they found and suggestions for improvements.

Consultation Services – Workplace Stress Reduction

This option is a more thorough concept for implementing b., specifically designed around Workplace Stress. The goal would be to develop an occupational total worker health practice internship training program in collaboration with the Center for Social Epidemiology led by Dr. Peter Schnall for ERC-supported students to be able to go to businesses and offer to conduct a workplace health survey/screening about psychosocial stressors and health outcomes such as obesity/high blood pressures, etc.

The workplace evaluation would use survey instruments to assess psychosocial stressors and psychological health outcomes and might also include assessment of physical health outcomes such as weight or blood pressure. The collected data would be entered into a computer software program, analyzed and a report prepared for the worksite with recommendations for workplace interventions that would also provide tools for employees and managers for dealing with stressors.


The Center intends to develop an online newsletter that includes new research findings and aggregates articles on occupational health and safety and provides links to additional resources.

Cleaning Workers Research Database

NORA Services Sector, Accommodations Subgroup
(updated 1/23/14)

Bello A, Quinn MM, Milton DK, Perry MJ [2013]. Determinants of exposure to 2-butoxyethanol from cleaning tasks: a quasi-experimental study. Ann Occup Hyg. 57(1):125‒135.

Abstract. BACKGROUND: The quantitative assessment of airborne cleaning exposures requires numerous measurement methods, which are costly and difficult to apply in the workplace. Exposure determinants can be used to predict exposures but have yet to be investigated for cleaning activities. We identified determinants of exposure to 2-butoxyethanol (2-BE), a known respiratory irritant and suspected human carcinogen, commonly found in cleaning products. In addition, we investigated whether 2-BE exposures can be predicted from exposure determinants and total volatile organic compounds (TVOCs) measured with direct reading methods, which are easier to apply in field investigations. METHODS: Exposure determinants were studied in a quasi-experimental study design. Cleaning tasks were performed similarly as in the workplace, but potential factors that can impact exposures were controlled. Simultaneously for each task, we measured concentrations of (1) 2-BE according to the National Institute for Occupational Health and Safety 1430 method and (2) TVOC with photoionization detectors (PIDs). Simple and multiple linear regression analyses were performed to identify 2-BE exposure determinants and to develop exposure prediction models. RESULTS: Significant determinants from univariate analyses consisted of product type, tasks performed, room volume, and ventilation. The best-fit multivariable model was the one comprised of product type, tasks performed, 2-BE product concentration, room volume, and ventilation (R(2) = 77%). We found a strong correlation between the 2-BE and the TVOC concentrations recorded by the PID instruments. A multivariable model with TVOC explained a significant portion of the 2-BE concentrations (R(2) = 72%) when product type and room ventilation were included in the model.

CONCLUSIONS: Our results suggest that quantitative exposure assessment for an epidemiologic investigation of cleaning health effects may be feasible even without performing integrated sampling and analytic measurements.


Colt JS, Karagas MR, Schwenn M, Baris D, Johnson A, Stewart P, Verrill C, Moore LE, Lubin J, Ward MH, Samanic C, Rothman N, Cantor KP, Beane Freeman LE, Schned A, Cherala S, Silverman DT [2011]. Occupation and bladder cancer in a population-based case-control study in Northern New England. Occup Environ Med 68(4):239‒249. 

Abstract: OBJECTIVES: We used data from a large, population-based case-control study in Maine, New Hampshire, and Vermont to examine relationships between occupation, industry and bladder cancer risk. METHODS: Lifetime occupational histories were obtained by personal interview from 1158 patients newly diagnosed with urothelial carcinoma of the bladder in 2001-2004, and from 1402 population controls. Unconditional logistic regression was used to calculate ORs and 95% CIs, adjusted for demographic factors, smoking and employment in other high-risk occupations. RESULTS: Male precision metalworkers and metalworking/plasticworking machine operators had significantly elevated risks and significant trends in risk with duration of employment (precision metalworkers: OR 2.2, 95% CI 1.4 to 3.4, p(trend) = 0.0065; metalworking/plasticworking machine operators: OR 1.6, 95% CI 1.01 to 2.6, p(trend) = 0.047). Other occupations/industries for which risk increased significantly with duration of employment included: for men, textile machine operators, mechanics/repairers, automobile mechanics, plumbers, computer systems analysts, information clerks, and landscape industry workers; for women, service occupations, health services, cleaning and building services, management-related occupations, electronic components manufacturing and transportation equipment manufacturing. Men reporting use of metalworking fluids (MWF) had a significantly elevated bladder cancer risk (OR 1.7, 95% CI 1.1 to 2.5). CONCLUSIONS: Our findings support the hypothesis that some component(s) of MWF may be carcinogenic to the bladder. Our results also corroborate many other previously reported associations between bladder cancer risk and various occupations. More detailed analyses using information from the study’s job-specific questionnaires may help to identify MWF components that may be carcinogenic, and other bladder carcinogens associated with a variety of occupations.



Zheng T, Cantor KP, Zhang Y, Lynch CF [2002]. Occupation and bladder cancer: a population-based, case-control study in Iowa. J Occup Environ Med 44(7):685–691.

Abstract: While considerable efforts have been made to investigate the role of occupation and industry in the risk of bladder cancer, many reported associations have not been consistent, and strong evidence of increased risk is apparent for few occupational groups. To further examine the issue, a large, population-based, case-control study was conducted in the state of Iowa among both men and women. A total of 1452 incident bladder cancer cases and 2434 controls were included in the study. Occupational history was collected from respondents for each job held for 5 years or longer since age 16. Among men, excess risk was observed for industries including plumbing, heating, and air conditioning (odds ratio [OR], = 2.2; 95% confidence interval [CI], 1.0 to 5.0); rubber and plastic products (OR = 3.1; 95% CI, 1.2 to 8.5), motor vehicle parts and supplies (OR = 4.5; 95% CI, 1.2 to 16.5), and occupations including supervisors for transportation and material moving (OR = 6.5; 95% CI, 1.4 to 29.9), material-moving-equipment operators (OR = 1.9; 95% CI, 1.0 to 3.6), automobile mechanics (OR = 1.6; 95% CI, 1.0 to 2.6), painters (OR = 2.7; 95% CI, 1.0 to 7.7), and metal- and plastic-working machine operators (OR = 2.0; 95% CI, 1.1 to 3.4). Among women, significant excess risk was observed for secondary school teachers and record clerks. Housekeepers and butlers and workers in laundering and dry cleaning were also at increased risk. In conclusion, these results suggest that occupational exposures may play a significant role in the risk of bladder cancer.
