Background and Objectives: Environmental health Literacy (EHL) pertains to the ability to comprehend and utilize Environmental data in order to make informed choices regarding one's health. The aim of this study is to evaluate EHL, encompassing Knowledge, Attitudes, and Behaviors (KAP) regarding general Environmental health (GEH) and Specific Environmental Media (air, food, and water), as well as their socio-demographic determinants. Materials and Methods: A descriptive study was conducted to examine the EHL of 678 women who visited comprehensive health centers in Zanjan city in 2023. Data was collected through multi-stage random sampling using the validated EHL Scale, and analyzed with SPSS 23 software at a significance level below 0. 05. Results: The study found that while most women have good knowledge of GEH (80. 7%), water (60. 3%), and food (90. 9%), only 26. 7% are knowledgeable about air HL. Additionally, 33. 9% had a positive attitude towards GEH, while only 13. 7% felt positively about air quality. Many participants showed limited knowledge (37. 5%) and a negative attitude (43. 8%) towards air quality. Significant correlations exist between age, marital status, economic status, training participation, and women's EHL. Conclusion: The level of women's GEH and specific Environmental media (air, food, and water) was high. However, their level of Literacy in air media was lower than the other areas. To enhance Environmental health Literacy, health authorities should capitalize on women's potential and introduce specific programs to boost their air Literacy.
