Exposures to environmental pollutants during windows of developmental vulnerability in early life can cause disease and death in infancy and childhood as well as chronic, non-communicable diseases that may manifest at any point across the life span. Patterns of pollution and pollution-related disease change as countries move through economic development. Environmental pollution is now recognize...
Plastics are uniquely flexible materials that offer considerable benefits as a simple packing to complex engineering material. Traditional synthetic polymers (often called plastics), such as polypropylene and polyethylene have been derived from non-renewable petrochemicals and known to cause environmental concerns due to their non-biodegradable nature. The enormous use of petroleum-based plasti...
Abstract Tehran is one of the most polluted cities in the world that this pollution has physical and psychological harmful consequences. This study an applied analytical methods based on library studies and documents for the purpose of utilizing the principles of environmental psychology and behavior analysis of citizens' attitudes in four categories; Due to importance of addressing the caus...
By employing the methods of Johansen cointegration test and granger causality test, the paper aimed at investigating the interactions of environmental pollution and economic growth in the process of Zhejiang’s industrialization according to the time series data of three kinds of pollution indices from 1981 to 2006. The results showed that three kinds of pollution indices all had a negative long...
The development of clean and renewable energy materials as alternatives to fossil fuels is foreseen as a potential solution to the crucial problems of environmental pollution and energy shortages. Hydrogen is an ideal energy material for the future, and water splitting using solar/electrical energy is one way to generate hydrogen. Metal-organic frameworks (MOFs) are a class of porous materials ...
Most of the hard-to-degrade keratin containing substrates like feathers or animal hairs is either discarded or incinerated, resulting in energy consumption and environmental pollution. Thus, an innovative eco-friendly method to deal with these wastes is urgently needed. Microbial degradation of keratin by keratinases has gained biotechnological interest in applications and represents a great op...
Cholesterol is a steroid commonly found in nature with a great relevance in biology, medicine and chemistry, playing an essential role as a structural component of animal cell membranes. The ubiquity of cholesterol in the environment has made it a reference biomarker for environmental pollution analysis and a common carbon source for different microorganisms, some of them being important pathog...
There is great interest in developing a low-power gas sensing technology that can sensitively and selectively quantify the chemical composition of a target atmosphere. Nanomaterials have emerged as extremely promising candidates for this technology due to their inherent low-dimensional nature and high surface-to-volume ratio. Among these, nanoscale silicon is of great interest because pristine ...
In recent years demolished concrete waste handling and management is the new primary challenging issue faced by the countries all over the world. It is very challenging and hectic problem that has to be tackled in an indigenous manner, it is desirable to completely recycle demolished concrete waste in order to protect natural resources and reduce environmental pollution. In this research paper ...
