Examining the indoor air environment of public venues, especially populated supermarkets such as Co-Ops in Kuwait, is crucial to ensure that these venues are safe from indoor environmental deficits such as sick building syndrome (SBS). The aim of this study was to characterize the quality of the indoor air environment of the Co-Ops supermarkets in Kuwait based on investigation of CO2, CO, NO2, H2S, TVOCs, and NMHC. On-site measurements were conducted to evaluate these parameters in three locations at the selected Co-Ops, and the perceived air quality (PAQ) was determined to quantify the air&rsquo ; s pollutants as perceived by humans. Moreover, the indoor air quality index (AQI) was constructed for the selected locations, and the ANOVA test was used to analyze the association between the observed concentrations among these environmental parameters. At least in one spot at each Co-Op, the tested environmental parameters exceeded the threshold limit set by the environmental agencies. The PAQ for Co-Op1, 2, and 3 are 1.25, 1.00, and 0.75 respectively. CO2 was significantly found in an association with CO, H2S, and TVOCs, and its indoor-outdoor concentrations were significantly correlated with R2 values ranges from 0.40 to 0.86 depending on the tested location.

Globally, compact fluorescent lamps (CFLs) are increasing consistently, and Kuwait is not an exception. However, these lamps contain mercury, which is highly injurious to human health and the environment. This study assessed Kuwaiti respondents' awareness using a large-scale national survey conducted on a random sample of 6210 individuals (response rate 84.3%). The questionnaire was comprised of four sections and utilized skip logic branching. The modes were paper-based, face-to-face interviews, and electronic structured questionnaires. Data were also analyzed through the Pearson chi-square test to know the significant differences in lamp type preferences and the reasons for the preferences. Almost half of the participants (51.4%) knew the difference between incandescent and fluorescent lamps. Only 11.1% were using incandescent lamps solely in their houses. The remaining 88.9% used fluorescent lamps (38.4%) or both types (50.5%). The results showed that 48.3% think fluorescent lamps save energy, whereas 81.3% of people were unaware of their mercury content. The knowledge patterns towards breakage showed that respondents who chose the proper response were 31.9% for evacuation, 14.6% for aeration, and 7.3% for turning off the AC. The awareness of populations to take appropriate actions towards proper disposal was very poor in case of fluorescent lamp accidental breakage or when it completes its life cycle because most of them did not know about the proper evacuation, aeration, and cleanup measures. These findings are beneficial for the government and policymakers to take essential steps to create relevant awareness channels among the country's communities for safety from expected health hazards.
