This study aims to determine the air pollution in Karabük province. For this purpose, a new equipment has been designed. The equipment can measure the SO2, CO2, CO, CH4, NOX, O3, PM2.5, and VOC pollution alongside with many atmospheric parameters. The measurement period has been decided to be one year starting from June 2021. The measurement period was one year, starting from June 2021. The measurements were taken at fifty points with 8 portable intermittent equipment. Then hourly and monthly averages were calculated. The calculation of the averages depends on many statistical analyses. The mean (geometric, harmonic, root, interquartile, Winsorized), median, midrange, Skewness, and Kurtosis analyses were done to obtain correct daily, and monthly averages. These analyses are necessary to comment on the intermittent measurement averages. The analyses of the collected data showed that the concentrations are changing considerably through the measurement period. The highest concentration was observed for the SO2, CO, NOX, and PM2.5 with respective values of 186.4, 170, 204.9, and 265 µg/m3. All these values are dangerous for human health. Elevation, temperatures, atmospheric pressure, and wind are sensitive parameters for atmospheric pollution. In Karabük province, most of the measurement points are affected by multi-pollution sources. The scatter diagrams also support this fact. During winter months, the pollution increases instantly. However, O3 and VOC parameters show different trends as compared to other pollutants. The concentration of these two parameters, namely O3 and VOC, increases during spring months. The O3 and VOC increase by 78.1%, and 43.2%, respectively due to photochemical reactions in the atmosphere in spring.

This study investigates the physical growth disparities between Low Birth Weight (LBW) and Normal Birth Weight (NBW) babies aged 24-36 months in a selected hospital in Dhaka. The research sample comprised 200 babies, evenly split between LBW (birth weight < 2500 grams) and NBW (birth weight ≥ 2500 grams) groups. Physical growth parameters including weight, height and head circumference were measured and analyzed using descriptive statistics and comparative tests. The findings reveal significant differences in all measured parameters between LBW and NBW infants. LBW babies exhibited lower mean values in weight (11.5 kg vs. 13.0 kg), height (85.0 cm vs. 89.0 cm) and head circumference (48.0 cm vs. 49.0 cm) compared to NBW babies. Statistical analyses confirmed these differences to be significant (p < 0.05), highlighting the persistent impact of birth weight on early childhood growth. These results underscore the importance of targeted healthcare interventions for LBW infants to mitigate growth disparities and promote optimal development. Early childhood growth failure in LBW infants has long-term implications for health and developmental outcomes, necessitating comprehensive healthcare strategies that include nutritional support, growth monitoring and developmental assessments. By addressing these challenges, healthcare providers and policymakers can improve the long-term health and well-being of LBW infants, ensuring they have the opportunity to achieve their full developmental potential. This study contributes valuable insights to the field of maternal and child health in Bangladesh, guiding future research and healthcare initiatives aimed at supporting LBW infants and reducing health disparities.
