Ammonia Production From Cattle At The Walter C. Todd Agricultural Research Center, Sydney Cunningham, Elizabeth Smith, Rachel Nelson, Brayden Wagner

Undergraduate Research Conference

The Walter C. Todd Agricultural Research Center cattle pen was tested to measure the ammonia emission rates produced by cattle. Samples were collected from six testing locations. Eighteen samples were taken across three days of testing, in 8-hour increments. We found that small-scale cattle in open-air pens produce minimal amounts of ammonia that are not a concern for air quality. Ammonia was detectable in small quantities in the testing sites adjacent to the cattle and not in locations more than 0.1 miles away.

All Peer-Reviewed Publications

Crop diversification is associated with ecosystem services that can improve yield. We integrated tomatoes and kales within the cereal push-pull technology (PPT), to form the vegetable integrated push-pull (VIPP), and explored the influence of these cropping systems on pest and disease management, and subsequent yield of the vegetables. Aphids and diamondback moths (DBM), the major pests in kale production, together with grasshoppers were consistently lower in the VIPP plots. Low incidences and damage by leafminers, whiteflies and fruitflies on tomatoes were observed in VIPP plots compared to plots of tomato intercropped with maize (control). The severity of black rot and …

Articles

Environmental exposures, including widespread industrial pollution, impact human health and are amplified in more highly exposed communities. Policy and regulatory frameworks for making decisions and recommendations on interventions to mitigate or prevent exposures tend to narrowly focus on exposure and some health-related data related to risks. Typically, such frameworks do not consider other factors, including essentiality, health equity, and distribution of benefits and costs. Further, decisions and recommendations lack transparency regarding how they were developed. We developed the Navigation Guide Evidence-to-Decision Framework for Environmental Health (E2DFEH) to provide a structured and transparent framework incorporating a range of scientific information and …

Evaluations Of Hand-Arm Vibration (Hav) Exposure And Related Vascular And Musculoskeletal Heath Effects Among Groundskeeping Workers In Southeastern U.S., Nathan Chen

All ETDs from UAB

Long-term, excessive exposure to hand-arm vibration (HAV) may induce vascular, neurological, and musculoskeletal disorders, collectively known as hand-arm vibration syndrome (HAVS). However, concerns arise when adopting the currently available guidelines and standards to protect workers who regularly use vibrating tools due to the lack of standardized exposure assessment methods for HAV and reliable health indicators for HAVS. The existing exposure-response relationship addressed in ISO 5349-1 was developed based on epidemiological studies predominantly performed in temperate zones. Thus, this dissertation aimed to evaluate the HAV exposure levels and vascular and muscular health effects from vibration exposure among groundskeepers in the southeastern …

Ms Environmental Biology Capstone: Evaluating Environmental Risks And Conflicts In Golf Course Landscapes, Meredith Boos

Regis University Student Publications (comprehensive collection)

1) This review investigates the relationship between pesticide use on golf courses and in agriculture to determine whether the adverse health effects documented in agricultural settings also apply to golf course environments. While the negative health effects from agricultural pesticide use are well established, golf courses use pesticides with greater frequency and intensity, suggesting a potentially higher exposure risk for both workers and players.

2) This study proposes methods to quantify pesticide bioaccumulation on golf courses and adjacent lands. We hypothesize that areas surrounding golf courses will exhibit a spatial gradient of pesticide accumulation, increasing with proximity to treated sites …
