Volume 9, Issue 4 (3-2017)
Abstract

Background and Objective: The aim of present study was to assess environmental inequality in long-term exposure to outdoor air pollution in 22 districts of Tehran in 2012.

Materials and Methods: The present study is an ecological study and concentration index was used for assessment of inequality. In this study the amounts of pollutant concentrations (PM10, NO2, SO2) obtained were based on land use regression (LUR) for exposure assessment. Variables that their effects have been studied on the distribution of exposure to pollutants included: education level, employment status and car ownership, which were obtained from census demographic and Tehran Municipality's dataset.

Results: The concentration index for PM10 in the case of illiteracy, people with higher education and private car owners was 0.059 (0.004-0.113), -0.056 (-0.001- -0.110) and -0.079 (-0.031- -0.127), respectively. These relationships were statistically significant. Concentration index for PM10 was 0.016 for the workers population, which was not statistically significant. For NO2 and SO2, no inequality was found in illiterate people, people with higher education, employees and car owners.

Conclusion: This study showed that there was significant inequality in terms of exposure to PM10 between different regions of Tehran in the illiterate, people with higher education and car owners. Considering these subgroups of population can be helpful in policy-making process.


Orchard farmers’ attitudes towards pesticides waste management in Meshkinshahr county, Iran

Volume 13, Issue 3 (11-2020)
Abstract
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.
