This work focused on the development and validation of the analytical procedure using gas chromatography equipped with vacuum-ultraviolet detection for the specific and sensitive determination of nine photoinitiators in food packages. Subsequently, a comparison of the combination of vacuum ultraviolet spectroscopy with gas chromatography and a developed gas chromatography with mass spectrometry method was performed. The vacuum-ultraviolet spectra of all tested photoinitiators were collected and found to be highly distinct, even for isomers. Under the optimal conditions, the limits of detection for nine photoinitiators ranged from 1 to 5 mg/L using vacuum ultraviolet detection and from 0.15 to 0.5 mg/L using mass spectrometric detection. Both techniques were successfully applied for screening of photoinitiators in seven kinds of food packages and the obtained data showed good agreement (the relative difference was between 3 and 18%). The variability in concentrations found in triplicate samples was assessed to be below 18%. Predominantly benzophenone was found in all analysed samples in the range of 0.31-4.23 mg/kg. It appears to be preferably selected by food packaging manufacturers. This study proposes a new simple and sensitive technique used for analysis of photoinitiators that could be a good alternative to gas chromatography with mass spectrometry.

Background: Primigravidas are at high risk of experiencing emotional disorders, stress, anxiety, and depression, which can lead to fetal neglect and a lack of adequate pregnancy care. This may result in problems with fetal growth and development, low birth weight, and even infant death. A strong maternal-fetal attachment significantly influences pregnancy care practices. However, there is no prenatal attachment education program included in routine education. Aim: This study aimed to explore healthcare workers' perspectives on the need to develop a prenatal attachment education package for pregnant women in public health centers. Methods: This qualitative study was conducted among eight healthcare workers from eight public health centers in Bantul, Yogyakarta, Indonesia; a regency with the seventh highest infant death rate in the country. Inclusion criteria included healthcare workers in maternity and child health units who resided in Bantul and agreed to participate. Purposive sampling was used to recruit the participants. Data collection was conducted through focus group discussion (FGD) with an interview guide. The FGD data were transcribed and analyzed using NVivo 12 Pro International software. Results: The findings identified 216 codes, 16 categories, and 4 themes, including (1) pregnancy education program, (2) maternal-fetal attachment education program, (3) pregnancy emotional management program, and (4) husband support education program. Conclusion: This study identified four themes and sixteen categories that underscore the need for further research to develop guidelines, materials, and media for prenatal attachment education packages.
