Abstract

Indoor air quality is something that describes the indoor air quality in a building suitable for human activity and comfort. The purpose of this research was to determine indoor air quality based on NO2 levels in the air and No2-N levels resulting from dehumidifier absorption. The research was conducted on June 20 2023 and June 27 2023 in the materials room of the environmental quality laboratory faculty of civil engineering and planning (FTSP UII) Yogyakarta. In the morning at 08.00 WIB and in the afternoon at 16.00 WIB with each measurement for 60 minutes. The research method used in this research is quantitative research with data analysis techniques descriptive analysis. In the material room, the nitrogen dioxide (NO2) parameter does not meet the NAV while the NO2-N parameter meets the NAB.

Abstract

Urban areas often face greater environmental pollution challenges compared to rural areas, primarily due to high population density, industrial activities, and inadequate waste management systems (Huang et al., 2012). Well water, frequently used as a drinking water source in many urban areas, is susceptible to contamination by various pollutants, including Bisphenol A (BPA) This study aims to monitor BPA levels in well water in urban areas as an indicator of environmental pollution  Well water samples from several strategic locations were analyzed using UV-Vis spectroscopy, an effective technique for detecting and measuring BPA levels in water The results showed variations in BPA concentrations by location. For instance, in Pakem, BPA concentrations ranged from 0.68 to 1.91 mg/L, in Ngemplak from 0.27 to 3.55 mg/L, and in Ngaglik from 1.37 to 1.91 mg/L. No direct pattern was found linking BPA concentration to population density. This variation is likely due to environmental factors, industrial activities, or consumption habits of the urban population. Although some locations have BPA concentrations below the EPA's safe contamination limit, this study highlights the importance of monitoring and managing health risks associated with BPA pollution in urban areas.
