Background and Objective: A scientific questionnaire for assessing the knowledge, attitude and judgment of people on waste management by municipalities has not been developed so far. Therefore, the purpose of this study was to design and validation of an instrument to assess the knowledge, attitude and judgment of people on waste management by municipalities.
Materials and Methods: This analytical study was conducted in District 21 of Tehran in 2017. The initial items of the questionnaire were designed based on previous studies and opinions of the team of specialists and people. Then, the face validity and the content validity of the designed questionnaire was examined. The face validity and the content validity was examined qualitatively and quantitatively, respectively. Finally, the reliability of the attitude and knowledge and evaluation of municipal performance items were measured by Cronbach's alpha and a test-retest method, respectively.
Results: The initial questionnaire had 43 items. In the face validity, 8 items were removed and 8 items were edited. In quantitative content validity, 7 items were excluded, with the content validity index of less than 0.79 and the content validity ratio less than 0.49. Pearson correlation coefficient obtained for knowledge component equal to (r=0.77, p<0.0001) and for component performance (r=0.93, p<0.0001), respectively. Cronbach's alpha coefficient was equal to 0.89 for items attitudes, which were in an acceptable level.
Conclusion: The questionnaire can be used as a valid research instrument to collect information on knowledge, attitude and judgment of people on waste management by municipalities.
 

Background and Objective: Nowadays, with the increasing environmental issues such as energy crisis, climate change, waste generation and destruction of natural resources and the increase of waste materials due to the development of urbanization, human impact on the environment is one of the most challenging issues of the scientific community. The purpose of this study was to measure the level of awareness and environmental behaviors of Yazd citizens.
Materials and Methods: This cross-sectional study was carried out on 1000 residents of Yazd in 2018 by cluster sampling. The data collection tool was a standard questionnaire for knowledge, attitude and environmental behavior. The score range for the three knowledge, attitude and practice structures was 0-12, 13-65, and 17-55, respectively. Data were analyzed using descriptive statistics and analytical tests at the significance level of 0.05 using spss16 software.
Results: One hundred percent of the questionnaires were completed. Mean score of knowledge and environmental attitude was 8.23 ± 3.92 and 36.15 ± 8.28 (moderate), and of the environmental behavior was 26.19 ± 7.14 (poor). There was a significant statistical difference between knowledge and environmental behavior of women and men. The level of knowledge and environmental behavior of women was higher (p<0.05). The largest source of environmental information was radio and television (42%).
Conclusion:  Despite the relatively good awareness and attitude towards the environment, the majority of the people had poor performance due to the environmental behavior. Therefore, environmental awareness cannot be a guarantee of environmental behavior. It also needs to encourage persuasive social conditions and structure and facilitating environmental behaviors.
 

Background and Objective: Water is one of the most valuable environmental factors that has become one of the greatest challenges of human society today. The purpose of this study was to investigate the relationship between religious attitudes toward water saving in high school students in Yazd.
Materials and Methods: This cross-sectional descriptive study was conducted in 2018. 600 subjects (300 girls and 300 boys) were selected by random sampling method. The data collection tool was a questionnaire on water saving tendency including 21 questions and Religious attitude questionnaire including 60 questions. The score range for the religious attitude and the tendency to save water was 60-300 and 21-105, respectively. Data were entered into SPSS18 software and analyzed using Chi-square, Pearson correlation coefficient and descriptive statistics.
Results: The mean and standard deviation of the religious attitude score and the tendency to save water consumption were 180.11 ± 14.31 and 65.27 ± 10.21, respectively. The religious attitude of students with age and gender, and the tendency toward water saving with gender variables and number of family members was significant (p<0.05). Correlation between religious attitude and tendency to water saving was statistically significant (r=0.69, p=0.01)
Conclusion: Considering the positive correlation between religious attitude and tendency towards water saving, efforts to strengthen religious and moral inputs related to water consumption in students can lead to the development of an optimal water consumption attitude in this influential community of a society.
 

Background and Objective: Pesticides are the major components of production in modern agriculture, however, as their widely usage, the hazards associated with their wastes have become of increasing concern. The aim of this study is to investigate orchard farmers’ attitudes toward proper disposal of pesticide wastes.
Materials and Methods: The statistical population of the study includes all orchard farmers in Meshkinshahr County (N=32,300). A total sample size of 300 farmers was selected and the data were collected. The research instrument was a questionnaire which was validated by a panel of university staff. A pilot study was conducted with 30 farmers outside the sample villages and Cronbach's alpha showed high reliability of the instrument.
Results: Due to the pesticides use, significant amounts of wastes are produced annually. Farmers do not properly dispose pesticide wastes. They leave the wastes on the farm, dump it in canals or river flow, or burn it. Farmers were not well informed about triple rinsing of containers before disposal. Most farmers used masks, hats, and gloves, 53% used boots and 7.7% used goggles, though none of them used coverall during pesticides’ handling. Respondents took negative to moderate attitudes towards proper wastes disposal. Age, education, and participation in extension programs were the most important determinants of the attitudes.
Conclusion: Considering the relatively negative attitude and improper waste disposal, it is necessary to establish centers for waste collection, to inform and encourage farmers to dispose of waste properly. Relevant organizations, such as health and the environment should plan for pesticide waste management.

Background and Objective: pesticides are essential to protect plants from pests and diseases. Extensive and unsafe use of pesticides by farmers pose various risks to human health and the environment. Therefore, the present study evaluates farmers' knowledge, attitudes, and behaviors regarding pesticides use and the health problems associated with their use.
Materials and Methods: In this human-research survey the target population consisted of 6170 farmers and fruit growers in Galogah County, Mazandaran province, were included. Multi-stage cluster sampling was used to select samples within 2 sub-districts and 13 villages, and the information was collected through 379 questionnaires. Statistical tests such as Mann-Whitney U, Kruskal-Wallis H, Spearman Correlation and Linear Regression were used to analyze the obtained data.
Results: The respondents have no sufficient knowledge regarding the safe use of pesticides. Respondents' attitudes toward the impacts of pesticide use were positive. The safety measures were less considered by majority of respondents. Moreover, the results revealed that personal protective equipment (mask, gloves and, goggles) and safe disposal of pesticide residues are not fully taken into consideration. The dizziness, skin problems, headache and vomiting were the most common symptoms of pesticide-related illnesses. The findings of regression analysis showed that wide range of knowledge and proper attitudes about the safe use of pesticides are beneficial and can act as the promoting factor in farmers' safety behavior regarding pesticides use.
Conclusion:  In conclusion, providing pesticide users with sufficient knowledge, safety information and effective personal equipment such as wearing masks, goggles and gloves should be given highest priorities.

Background and Objective: Today, the issue of health aspects in urban waste management, especially recycling, has received a lot of attention during Covid-19 around the world.

The level of knowledge was about 80 percent and the lack of awareness was 20 percent. The level of workers' positive attitude, negative attitude, and lack of attitude were 79.71, 14.56, and 5.72 percent, respectively. The level of positive practice among workers was about 67.43 percent and the negative practice was 32.57 percent.
Conclusion: The results clarified that in order to succeed in waste management programs in recycling centers, municipal waste managers should pay more attention to educational aspects, especially through the focus on programs and their development and adaptation for different age groups, especially 20 to 40 years.
 

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.

Background and Objective: The purpose of this study is to evaluate the difference in knowledge, attitude, and performance in terms of food hygiene and safety between people with and without a history of Covid-19.
Materials and Methods: This descriptive-analytical study was conducted on 712 people from August to September 2021 using a standard online questionnaire. The questionnaire had four sections, the first section includes demographic information, the second section includes seven questions related to participants' knowledge about food hygiene and safety, the third section includes ten questions about participants' attitudes, and the fourth section contains 10 questions related to participants' health performance. Multiple regression models were used to investigate the main predictors of knowledge, attitude, and performance. The significance level was considered as p < 0.05.
Results: There were 271 (43%) people with a history of infection and 361 (57%) without infection. Demographic factors were not significantly different between people with and without a history of infection. The results of the present study showed that knowledge (p=0.05) and people's performance (p=0.002)  about food hygiene and safety have a significant relationship with the history of corona infection. However, people's attitude was not affected by the corona infection (p=0.17). Attitude was the major predictor of performance (p <0.001).
Conclusion: It can be claimed that contracting Corona has increased people's knowledge and improved performance regarding food hygiene and safety during the Covid-19 pandemic and has improved health conditions.
 

Background and Objective: Nowadays, recycling is one of the ways to save mankind from the mass of waste it produces, and waste separation from the source is the first and most important link in the field of urban waste recycling. Since the necessity and basis of recycling is people's participation in separation plans from the source, the present study was conducted to investigate the awareness, attitude, and performance of the people of Mazandaran province regarding the source separation of household waste in 2021.
Materials and Methods: The present study was a descriptive-analytical and cross-sectional study, and the tool used in it was a researcher-made questionnaire including three dimensions of knowledge, attitude, and performance, the link of which was provided online to qualified people. The qualitative content validity of this questionnaire was confirmed by 8 environmental health experts in the field of the research subject. The reliability of the tool was also estimated through the Retest Method. Furthermore, the values of Cronbach's alpha coefficient for the three dimensions of awareness, attitude, and performance were calculated. In the following, the samples were selected in virtual groups based on the available sampling method and through the distribution of the questionnaire link online. Analysis of variance was used to compare the mean scores in the levels of variables, Pearson's correlation test was used to examine the relationship between the scores of awareness, attitude, and performance dimensions, and linear regression was used to examine the effect of independent variables. Finally, the data was analyzed in SPSS software (version 22).
Results: For the entire study population (305 people), the range and mean score of awareness were 0-6, and 5.03±1.18 respectively, the range and mean score of attitude were 17-85 and 61.01± 9.45, and the range and mean score of performance were 6-30 and 11.43±5.19, respectively. Also, there was a significant correlation between the mean scores of the dimensions of awareness and attitude (correlation coefficient=0.70), awareness and performance (correlation coefficient=0.68), and attitude and performance (correlation coefficient=0.63).
Conclusion: The results of this study, which was conducted to measure the knowledge, attitude, and performance of the people of Mazandaran province regarding the separation of household waste from the source and waste recycling, and with a survey of 305 households in this province, showed that although the most of people have a piece of proper knowledge and attitude related to the importance of separation and recycling of solid waste, they have not participated much in the plans of waste separation from the source. Therefore, in order to increase the level of people's performance, it is recommended to develop incentive programs in the field of source separation, including awarding prizes or applying discounts on waste charges, as well as providing suitable containers for waste separation to households for free by the municipality to encourage waste separation.

Background and Objective: Household hazardous wastes can pose significant risks to the environment, increase the death rate and dangerous diseases due to their quantity, concentration or physical, chemical, or biological quality. The purpose of this study was to determine the effect of educational intervention on the knowledge and attitude of health workers (Behvarzes) and health care workers of Ardestan city regarding household hazardous waste management.
Materials and Methods: This research was a semi-experimental interventional study conducted among 64 healthcare workers of the Ardestan health network in Isfahan province. A valid and reliable questionnaire was used to collect data. The data were entered into SPSS version 22 software for statistical analysis and analyzed through Mann-Whitney, Analysis of Variance (ANOVA) and paired T-tests.
Results: After the training, the average knowledge scores of Behvarzes and health-care workers in the sample group increased from 22.56±1.65 to 26.78±0.66, and their average attitude scores also increased from 89.37±2.67 to 95.31±2.71. The paired T-test showed a significant difference in the mean and standard deviation of knowledge and attitude scores in the intervention group before and after the intervention (p<0.05). The independent T-test did not show any difference in this regard according to the gender variable. The ANOVA test showed a significant difference between the different education groups after the intervention regarding the change in knowledge score or attitude according to education level (p<0.05).
Conclusion: The results of this study showed that the educational intervention for Behvarzes and healthcare workers was effective in raising their awareness and improving their attitudes towards the importance of household hazardous waste managemnt. Considering that the improvement of the household hazardous waste management system requires enhanced public awareness and attitude, as well as effective communication between Behvarzes, healthcare workers, and citizens, city managers can use the method employed in this study to organize regular training programs on household hazardous waste management.
