Background and Objective: In this study, we aimed to assess Iran’s position and trends for environmental health status among the countries of “Iran’s perspective document in 1404” according to the indicators used in Environmental Performance Index (EPI) report in 2018.
Materials and Methods: The score of indicators in environmental health area; air quality (including household solid fuels, exposure to PM_2.5, and PM_2.5 exceedance), water and sanitation (including drinking water and sanitation) and heavy metals (including lead) were extracted for all studied countries as well as for the last and baseline (generally ten years prior to last report) years from EPI 2018 database. According to EPI scores, the performance of the studied countries in each indicator was ranked. The percent change in the score of each indicator from baseline to current year was calculated and compared with the mean percent change for all studied countries.
Results: Iran ranked 7^th regarding air quality in 2016. Also, it ranked 6^th, 8^th, and 9^th in terms of household solid fuels, exposure to PM_2.5, and PM_2.5 exceedance, respectively. The EPI score for Iran regarding water and sanitation was 54.4 in 2005 and 58.74 in 2016 (percent change=7.98%). Iran ranked 21^st in 2005 regarding lead exposure index. Although this index showed a growth of 100% in 2016, which is very desirable compared to the average growth of all countries (34.47%), but only leads to one step up in the ranking of Iran and was ranked 20^th in comparison with other countries.
Conclusion: Totally, according to EPI 2018, Iran ranked 6^th in the field of environmental health issues among 23 countries of “Iran’s perspective document in 1404”. However, there is uncertainty in the accuracy of the EPI raw data used for calculating index scores. Hence, caution should be exercised in their interpretation.

Background and Objective: The current research aimed to evaluate the level of environmental knowledge, attitude, and performance of the citizens of Mazandaran province in 2021.
Materials and Methods: In a descriptive study, the level of environmental knowledge, attitude, and performance of the citizens of Mazandaran province were evaluated. The statistical population of the research (384 people) was selected by simple random method. In order to collect data, a questionnaire whose reliability was determined in previous studies was used. The collected data were analyzed using SPSS 21 software. Using Pearson's correlation test, the relationship between knowledge and environmental performance was analyzed.
Results: Among the 384 participants, only 135 answered all the questions. The results of the study showed that, despite the average knowledge of the citizens, the environmental performance is at a good level. The average score of environmental knowledge, attitude, and performance was 5.93±2.06, 47.67±9.30, and 58.70±12.69 respectively, and the most source of obtaining environmental information is television (46.7 percent) and social conversations (19.3 percent). The results of Pearson's correlation test show that there was a significant relationship between the awareness and environmental performance of citizens (p<0.05).
Conclusion: Despite the average knowledge of the citizens, their environmental performance was at a good level, but according to several reports, the Mazandaran province's environmental indicators are not in good condition, which indicates that probably mechanisms and other factors such as environmental policies and economic factors also affect people's environmental performance, which should be investigated.
