The increasing emergence of wildlife-origin infectious diseases poses a growing threat to both public health and ecological stability. The One Health approach offers a comprehensive framework that recognizes the interconnection of human, animal, and environmental health, emphasizing the need for integrated strategies in disease prevention. This review explores the role of wildlife rescue centers as strategic frontline platforms in a broader surveillance system. These centers, by systematically collecting and accumulating baseline health data from rescued wildlife, can contribute to the construction of a big data-driven monitoring network. Such a network not only enables early detection of pathogens but also supports long-term health monitoring of wildlife populations. Furthermore, it provides a scientific foundation for the conservation of endangered species, as many of these animals are frequently admitted to rescue centers due to disease or injury. We propose a comprehensive surveillance strategy that leverages the potential of data generated by wildlife rescue centers to enhance early warning systems, inform biosecurity policies, and strengthen ecosystem resilience. Ultimately, integrated disease monitoring will improve our capacity to detect, predict, and prevent infectious threats while safeguarding both biodiversity and public health. Furthermore, rescue centers play a pivotal role in collaborative research, public health preparation, and policy development, serving as essential hubs within the national disease control system.

Chelating agents like ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), and nitrilotriacetic acid (NTA) find extensive application in the removal of residual substances due to their high stability constants with a wide range of metal ions. They also play a crucial role in nuclear decontamination operations aimed at eliminating metallic radionuclides such as 60Co, 90Sr, and 239Pu. However, improper disposal of chelated radioactive waste can lead to significant increases in radionuclide migration rates from disposal sites. Therefore, it is imperative to comprehend the behavior of chelating agents under varying conditions, including pH, temperature, and metal ion concentrations. In this study, we present the results of a pH-dependent composition analysis of nickel-chelate complexes using UV-Vis spectrophotometry. Nickel (Ni) serves as an ideal metal ion for investigating its interactions with chelating agents due to its solubility over a wide pH range and high stability constants with all three chelating agents mentioned earlier. Initially, UV-Vis spectra of Ni-EDTA, Ni-DTPA, and Ni-NTA complexes were recorded at various pH levels. We assigned absorption maxima and compared our findings with existing literature on each Ni-chelate complex. Furthermore, we examined mixed samples of all three complexes, varying the pH to monitor changes in composition. The results and their implications will be presented in our poster presentation.
