Introduction: Correct and efficient use of various sources of energy and natural resources for sustainable development is necessary to achieve economic growth. Based on the importance preservation of non-renewable resources and reducing the negative impacts of industrial and economic activities more than ever are evident for governments. So, a descriptive study was conducted entitled “Tax...
background: volatile organic compounds (vocs) are human-made chemicals widely spread in the environment and produced by petrochemical industries and petroleum refineries. the aim of this research was to evaluate the distribution of vocs in the ambient air of mahshahr petrochemical complex, iran. methods: this study was a cross-sectional research performed in 2009. we used the method numbered 15...
Particulate matter (PM 2.5 and PM 10 ) ozone (O 3 are the two major air pollutants in China recent years. The fluctuations of , O strongly depend on weather processes anthropogenic emission. These may lead to existence short- long-term memory behaviors pollutants. Hence, here we use autoregressive parameter a first-order process [AR (1)] characterize short-term effects We estimate scaling expon...
Background: Air pollution has become an important factor restricting China's economic development and has subsequently brought a series of social problems, including the impact of air pollution on the health of residents, which is a topical issue in China. Methods: Taking into account this spatial imbalance, the paper is based on the spatial panel data model PM2.5. Respiratory disease mortality...
The increasing automobile vehicles and congestions in the world cause critical pollutions such as air and noise. Hence, we need comprehensive measures to reduce carbon dioxide (CO2) emission in transportation area. Many researchers have studied the impact of adopting ecofriendly vehicles such as electric vehicle (EV), hybrid electric vehicle (HEV), plug-in hybrid electric vehicle (PHEV), and fu...
The sample compartment for high-throughput synchrotron radiation circular dichroism (HT-SRCD) has been developed to satisfy an increased demand of protein characterisation in terms of folding and binding interaction properties not only in the traditional field of structural biology but also in the growing research area of material science with the potential to save time by 80%. As the understan...
Background and aims: Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds that are produced during the incomplete combustion of fossil fuels and petroleum products and are widely spread in the environment. Newsagents may be exposed to urban pollutions such as polycyclic aromatic hydrocarbons. The aim of this study was to assess the breathing zone exposure of newsagents to ...
