Abstract

Background: Indoor air quality (IAQ) is a critical factor influencing public health, especially in environments inhabited by vulnerable populations such as young children. Child Development Centres (CDCs) are particularly at risk of harboring airborne biological contaminants such as bacteria and fungi, which are affected by environmental variables including temperature and humidity. These contaminants can contribute to respiratory issues and other health complications. Objective: This study aimed to assess the levels of indoor temperature and relative humidity, evaluate bacterial and fungal concentrations, examine perceived health risks, and analyze the association between environmental parameters and microbial load in CDCs in Phatthalung Province, Thailand. Methods: A cross-sectional study was conducted at 20 CDCs from 1 to 27 February 2022, involving 59 staff members. Microbial air sampling was performed using settle plates based on gravitational sedimentation. Temperature and humidity were recorded at 8:30–9:30 AM and 2:30–3:30 PM. A structured questionnaire was used to assess health risk perceptions. Data were analyzed using descriptive and comparative statistics (p < 0.05). Results: Average temperatures were 24.51 ± 0.59°C and 25.03 ± 0.63°C, while relative humidity levels were 56.40 ± 5.08% and 56.30 ± 5.08%, respectively. Microbial loads met acceptable standards, yet significant differences were observed based on ventilation, cleaning frequency, number of children, and time of sampling. Over half of respondents recognized health risks from poor IAQ. Conclusion: While microbial concentrations were within acceptable limits, regular monitoring and effective ventilation systems remain essential to minimize potential health risks in CDCs.

Abstract

Background: Rapid technological advancement has changed consumer behavior, increasing demand for electronic devices, which are now essential in daily life. Objectives: To study the knowledge, attitudes, behaviors, and the factors influencing the related to electronic waste management of households. Methods: This cross-sectional descriptive study was conducted among households with 344 participants. A random sampling method was then used to select households from among those residing in Thung Khai Subdistrict, Yan Ta Khao District, Trang Province, Southern Thailand, between September 2024 to March 2025. The study questionnaire was given to the 344 participants. Descriptive statistics and chi-square test were used to analyze. Results:  Overall mean knowledge score of 11.28 (SD = 2.58), corresponding to the “moderate” category. The aggregate attitude score (M = 3.81, SD = 1.58), placing them in the “high” attitudinal category, and the overall mean behavior score of 2.14 (SD = 0.74), corresponding to a “fair” level of practice. Only prior exposure to information on electronic waste management demonstrated a statistically significant association with respondents’ self‐reported e‐waste behaviors (χ² = 17.89, p = .01). Conclusions: Thus, effective e-waste management is crucial for achieving sustainable development goals and requires collaboration across all sectors. Raising public awareness of circular economy principles is vital for enhancing community engagement in e-waste management.
