Disparities in Occupational Health Webinar

The Deep South Center ERC was honored to host Dr. Zeke McKinney on October 1, 2021, to speak on Disparities in Occupational Health.  Dr. McKinney is the Program Director for HealthPartners Institute where he holds an Occupational and Environmental Medicine Residency, and he is an Affiliate Assistant Professor at the University of Minnesota School of Public Health. 

BOA Member Ellen Hahn, PhD Presentation

Citizen Science and Policy Development to Reduce Environmental Exposures and Foster Environmental Justice

Monday, June 14 from 1245 – 1345 pm

Dr. Ellen Hahn is an environmental health nurse researcher from the University of Kentucky College of Nursing. Her work on tobacco control changed policy so that cigarettes, cigar, and vaping use was banned in restaurants, bars, and other public venues in Kentucky. At the time, it was the largest tobacco-producing state in the country. While she still focuses on tobacco control, she is now researching the effects of radon. Dr. Hahn is on the OHN advisory board for the Deep South Center for OHS, is the OHN Director for the Central Appalachian ERC, and will be speaking next week via ZOOM at the UAB SON PhD Program Intensive.

Evaluation of Aldehydes, Polycyclic Aromatic Hydrocarbons, and PM2.5 Levels in Food Trucks

A Pilot Study

Holden Phillips, MPH and Jonghwa Oh, PhD

Background: The food truck industry has rapidly expanded in the United States and kitchen environments can contain harmful contaminants from cooking emissions. The objective of this study was to examine the levels of aldehydes, polycyclic aromatic hydrocarbons (PAHs), and Particulate Matter (PM) 2.5 generated from cooking process in food trucks.

Findings: Formaldehyde was the only aldehyde detected in all samples with a concentration range of 7.16 to 53.68 μg/m3. No PAHs were detected above the limit of quantification. Average PM 2.5 concentrations ranged from 0.65 to 7.03 mg/m3. Food Trucks 1 and 2 have an average exhaust flow rate of 211 and 215 L/s per linear meter of hood, respectively.

Methods: Area sampling was performed twice at two participating food trucks during work shifts. Nine aldehydes and eighteen PAHs were analyzed according to the relevant standard methods while PM 2.5 was measured with a real-time monitor. Ventilation performance of the food truck exhaust hoods was also investigated using a thermal anemometer.

Conclusions/Application to practice: Overall, Food Truck 2 had consistently higher levels of aldehydes and PM 2.5 with comparable ventilation performance as Food Truck 1. The higher exposure levels of Food Truck 2 could possibly be attributed to a larger volume of food orders and the heavy duty cooking equipment with an exhaust flow rate below the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommendations. Although more investigations need to be performed, the findings could be used to raise awareness of food truck workers and health practitioners to reduce potential exposure risks.

Applying Research to Occupational Health Practice

The food truck industry in the United States has rapidly expanded in the past few years. Food truck environments are unique workplaces where workers use diverse thermal cooking appliances in a very limited space. In this pilot study, we examined the levels of contaminants generated through the cooking process within food trucks, including PM 2.5, aldehydes, and PAHs. In addition, the performance of the ventilation system of food trucks was also investigated. Our findings suggest potential exposure to formaldehyde and PM 2.5 with inadequate ventilation especially in a busier food truck, that is, higher emission and lower exhaust flow rate. Although more investigations need to be performed, the findings could be used to raise awareness of food truck workers and health practitioners to reduce potential risks of such exposures. Relatively simple engineering controls to improve the C&C efficiency of the existing ventilation system such as adding side panels to the hood and decreasing setback of the hood could be implemented wherever applicable.
