Native American And First-Nations Canadian And Physical Pfas Accumulations: A Literature Review, Laurel Liebeseller
Native American And First-Nations Canadian And Physical Pfas Accumulations: A Literature Review, Laurel Liebeseller
University Honors Theses
Native communities' exposure to anthropogenic Per- and Polyfluoroalkyl Substances (PFAS: "Forever Chemicals") are not demographically or geographically evenly distributed. Those who live near or on contaminated land or water are the most likely to accumulate dangerous amounts of PFAS that may have serious health consequences (Tribal PFAS Working Group 2021). Areas that tend to be most contaminated include landfills, airports, and military bases. Often Black, Indigenous People of Color (BIPOC) and low-income communities are placed near these "sacrificial zones" due to historic and current policies that segregate and marginalize people and families to polluted lands creating great environmental injustices (Dixie). …

Microbiological And Physicochemical Changes In Rabbit Meat During Ambient Storage, Marielle Gamboa, Dennis Marvin Santiago, April Shayne Sulabo, Mary Ann Torio
Microbiological And Physicochemical Changes In Rabbit Meat During Ambient Storage, Marielle Gamboa, Dennis Marvin Santiago, April Shayne Sulabo, Mary Ann Torio
The Philippine Agricultural Scientist
This study aimed to evaluate the changes in rabbit meat during storage at ambient temperature (30 ± 1ºC) for nine hours. The study focused on two rabbit muscle parts: the hind leg and the saddle, investigated in terms of microbiological parameters such as aerobic plate count (APC) and total coliform count (TCC); and physicochemical parameters such as pH, color, total myoglobin concentration, and lipid oxidation. Data obtained were subjected to statistical analysis at a 5% significance level (p < 0.05). Results revealed that the pH of both portions of rabbit muscle decreases over time during storage. This decrease is attributed to the growth of acid-producing microorganisms, which ultimately leads to spoilage in rabbit meat. On the contrary, color values (L*, a*, and b*) showed an increasing trend in both muscle portions, indicating a discoloration of rabbit meat during storage. Both lipid oxidation and total myoglobin content of rabbit meat did not change significantly during storage, but lipid oxidation varied between muscle parts. Based on the microbiological analysis of rabbit meat, both aerobic plate count (APC) and total coliform count (TCC) increased significantly during storage in both muscle portions. Results of the study suggest that freshly slaughtered rabbit meat must remain at ambient storage for the shortest time, as this storage condition will cause spoilage of meat, making it unfit for human consumption.

The Philippine Agricultural Scientist
This paper presents the properties of active films produced using cacao pods and calamondin peels. An active film is a type of packaging material that is made by incorporating the “active” ingredients for preservation on the packaging film rather than a direct application to foods. In this study, the conversion to active films was done by adding essential oils from lemongrass or calamondin peels, which are both known to exhibit antimicrobial properties. There were five film samples prepared for analysis: cacao-calamondin mixture; cacao-calamondin mixture with lemongrass essential oil; cacao-calamondin mixture with calamondin essential oil; cacao-calamondin mixture with encapsulated lemongrass essential …

Organic cucurbit growers face many challenges to production including insect pests, insect-vectored diseases, and non-vectored diseases. While Organic Material Review Institute (OMRI) -listed pesticides underperform at suppressing pests and diseases, some alternative pest management strategies hold promise, but little research exists on their cost-effectiveness. We compared the efficacy of mesotunnel systems (nylon-mesh netting row covers deployed over bent metal hoops) and OMRI-listed pesticides (fungicides and insecticides) on acorn squash across 2 years. During the early part of the season, before row covers were removed for pollination, we found 1.7 (2020) and 0.3 (2021) times more cucumber beetles in the uncovered …
