Background: Population growth and increased human activities in urban communities lead to large volumes of waste. This waste volume causes problems for human health and environmental pollution. Recently, a living environment assessment has been developed to improve the situation. The purpose of this study is to compare the environmental impacts of four urban waste disposal scenarios in Rasht ci...
The ethical markets are the place of supply and demand for goods and services that are standardized in social issues and take environmental concerns into account. The existence of these markets is essential for sustainable development. The objective of this paper is Determine the status of Iran among selected countries in the ethical market, using multi criteria decision making models. In this...
the relationship between some habitat factors and fish assemblage was analyzed in the taleghan river, alborz province, iran. fish specimens from thirty-three sites were sampled by electrofishing device in october 2014. the habitat parameters, including elevation (m), water depth (cm), river width (m), river slope (%), current velocity (m.s-1), number of large stone (> 15 cm), average stone diam...
One of the applied methods for environmental impact assessment is the index of global pollution (IGP) proposed by Rojanschi in 1991. This methodology enables the global estimation for the ecosystem state affected more or less by human activities. Unfortunately, Rojanschi’s method has a limitation; it can be applied only if at least three environmental components are considered. Frequently, many...
The sensitivity analysis of atomic force microscope (AFM) based manipulation of gold spherical nanoparticles in air medium has been carried out in previous research works. In the AFM-based manipulations conducted in various biological liquid mediums, the new environmental parameters associated with these biological fluids also affect the dynamics of the manipulation process. Therefore in this r...
Background and aims: Regarding development of several thermal indices and limitations of these indexes, in this research we were examined the applicability and validity of Modified discomfort index (MDI) in Outdoor occupational environments. Methods: This cross-sectional study was done on 175 subjects in summer (2016) in 12 mines construction materials of Tehran Province. Environmental...
background: given the increasing importance of suspended particles and reporting weather conditions in the amount of ultraviolet radiation in many countries, in this study, the data of the maximum amounts of pollution by suspended particles with the size of 10, 2.5 and1 microns (pm10, pm2.5, pm1) which were reported in 1-hour time-series and global ultraviolet index (uvi) were used to predict t...
the present study aims to analyze the existing indoor environmental conditions of firozabad city along with its impact on people’s health by going through the correlative index of indoor environment’s determinant and different diseases, faced by the people. in order to measure spatial disparities, the statistical technique, i.e. the standard score additive model (z- score), has been applied to ...
