One of the Challenging problems of Tehran metropolitan region is Air pollution. Suburban expansion in the form of sprawl patterns have created the travels and transportations, due to the dependence on personal vehicles contributes more than 85 percent of creators of air pollution. The article studied the role of transportation in emergence of urban air pollution in Tehran metropolitan region, h...
Background: It is believed that cognitive processing is easily disturbed by incompatible environmental stimulations. Many studies have shown that prenatal stress affects fetal brain development. The aim of this study was to evaluate the effect of noise pollution exposure during conception period on neural activity of hippocampus CA1 area in male rat offspring. Methods: Four groups of rats inclu...
Air pollution is associated with increased cardiovascular and pulmonary morbidity and mortality. The mechanisms of air pollution-induced health effects involve oxidative stress and inflammation. As a matter of fact, particulate matter (PM), especially fine (PM(2.5), PM < 2.5 μm) and ultrafine (PM(0.1), PM < 0.1 μm) particles, ozone, nitrogen oxides, and transition metals, are potent oxidants or...
In the present report the changes in mussels Mytilus galloprovincialis protein profile, as a reaction of water pollution, is presented. The antioxidant capacity was determined by the efficacy to scavenge the derived radical in mussel samples using the Trolox Equivalent Antioxidant Capacity (TEAC) assay. The highest percentage of inhibition was estimated in protein mussels from the dirty area (D...
The issue of whether adaptations to past disasters can impede adaptation to new disasters of a different type or intensity will be analyzed by examining the transition from frequent hurricanes to the Deepwater Horizon oil spill in coastal Louisiana. In particular, the effects of changed regulatory structures from the Stafford Act to the Oil Pollution Act of 1990 in response to the Deepwater Hor...
A significant degree of ploughness agricultural lands Ukraine has led to increased erosion and the creation soils varying degrees washout, which leads dehumification contamination with toxic substances. Therefore, purpose study was establish features horizontal migration accumulation heavy metals lead, cadmium, copper, zinc, trace elements boron manganese, radionuclides caesium strontium on pod...
Extreme weather events have become more frequent and are likely linked to increases in greenhouse gases and aerosols, which alter the Earth’s radiative balance and cloud processes. On 8–9 July 2013, a catastrophic flood devastated the mountainous area to the northwest of the Sichuan Basin. Atmospheric simulations at a convection-permitting scale with aerosols and chemistry included show that he...
A three–module ecological model for assessment of radiological consequences (EMARC) of accidental fallout was developed to estimate the internal dose. The model was adapted for ecological and economic conditions of Ukraine after the Chernobyl accident. The model takes into account the main natural mechanisms of changes in level of agricultural production pollution such as transformation of bioa...
There are at least five general reasons why market-based policies fail to address some of the most basic environmental objectives. This study evaluates the available biophysical and economic data against these criteria and concludes that marketbased approaches should be employed cautiously in pollution control under the present system and the available technology for farming in the lake area. T...
