Abstract
Background and aim: The chromium mist generator is an essential tool for research and for making evidence-based recommendations in evaluating air pollution and its control systems. The purpose of this study was to design and construct a homogeneous chromium mist generator and to look at the effects of factors such as sampling height and distance between samplers in side-by-side sampling on the chromium mist sampling method.
Material and Methods: First we developed a mist generator, using a chromium electroplating bath in pilot scale. Concentrations of CrO3 and sulfuric acid in plating solution were 125 g L-1 and 1.25 g L-1, respectively. To set up permanent air sampling locations, a Plexiglas cylindrical chamber (75 cm height, 55 cm i.d) was installed as the bath overhead. Sixty holes were made on the chamber in 3 rows (20 in each row). The distance between rows and holes was 15 and 7.5 cm, respectively. Homogeneity and the related factors were studied using a side-by-side air sampling method. Forty-eight clusters of samples were collected on polyvinyl chloride (PVC) filters contained in sampling closed-face cassettes. Cassettes were located 35, 50, and 65 cm above the solution surface with < 7.5 and/or 7.5-15 cm distance between heads. All samples were analyzed by the NIOSH method 7600.
Results: ANOVA tests showed no significant differences between locations in side-by-side sampling (P=0.82) or between different sampling heights or sampler distances (P=0.86 and 0.86, respectively). However, there were notable differences between means of coefficients of variation (CV) in various heights and distances.
Conclusion: We conclude that the most chromium mist homogeneity could be obtained at a height of 50 cm from the bath solution surface and with a distance of < 7.5 cm between samplers.

Abstract
Background and Aim: The return of working mothers to the workplace after maternity leave is a critical and complex stage in women's career paths, influencing the balance between their familial and professional roles. Understanding the challenges at this stage is essential for improving policies and support systems.
Materials and Methods: This qualitative study, employing content analysis, was conducted in 2025 at Zahedan University of Medical Sciences. The study population included employed mothers after childbirth and health sector managers. Data were collected through semi-structured interviews and analyzed using conventional content analysis. Ethical principles and data validation were emphasized.
Results: A total of 30 participants, including 20 employed mothers’ post-childbirth and 10 managers, were included. The findings were categorized into five main themes: psychological, familial, organizational, cultural and social, and legal and supportive challenges, encompassing 13 subthemes and 34 distinct codes.
Conclusion: According to the findings, revising organizational policies, enhancing legal awareness, and providing a flexible and supportive work environment for employed mothers are essential. Given the unique cultural and social characteristics of Sistan and Baluchestan province, this study can guide policymakers and health managers in improving working conditions for mothers.
