Toxic odour causes pollution to environment. Removal of odour from wet processing sections of leather tanneries is important to preserve safety and occupational health. Such odour causing gases are identified in nature and are identified mostly as ammonia, Hydrogen sulfide and Volatile organic compounds. These gases, evolving from tanning drums, were experimentally quantified and analysed. Tech...


 Along with global economic development and population growth, the discharge of highly toxic corrosive anthropogenic byproducts into atmosphere or aquatic habitats creates a serious threat to human health. In order remove such byproducts, more attention should be paid innovative materials high uptake capacity performance. Metal-organic frameworks (MOFs) are crystalline, porous, hybrid tha...

Nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (ANFO) explosive at the Sungun surface mine, located in the northwest of Iran. The pollutants were monitored during some blasting operations at the mine. It was concluded that the gases and dust clouds initially went up to the ...

The microemulsion is the emulsion with dimension of molecules approx. micrometre and smaller. Such microemulsion of water and diesel oil creates new quality and lets on obtainment ecological and economic of effects, as well as eliminates the disadvantageous influence common emulsions, or unprofitable effects of the injection of water to inlet system of the engine, direct to combustion chambers,...

Inhalations of atmospheric pollutants, especially particulate matters, are known to cause severe cardiac effects and to exacerbate preexisting heart disease. Heart failure is an important sequellae of gaseous inhalation such as that of carbon monoxide. Similarly, other gases such as sulphur dioxide are known to cause detrimental cardiovascular events. However, mechanisms of these cardiac toxici...

Septic tanks [1] are enclosed areas made for accumulation of decomposed domestic wastes, sewerage and its resultant gases. Sewer gases can be both toxic and non-toxic. Its major component is Methane [2], which can be extremely toxic in high concentrations. Sewer gas is a mixture of Hydrogen Sulphide, Ammonia, Carbon-dioxide, Nitrogen dioxide, Sulphur dioxide and sometimes, even carbon monoxide....

On-farm manure storage pits contain both toxic and asphyxiating gases such as hydrogen sulfide, carbon dioxide, methane, and ammonia. Farmers and service personnel occasionally need to enter these pits to conduct repair and maintenance tasks. One intervention to reduce the toxic and asphyxiating gas exposure risk to farm workers when entering manure pits is manure pit ventilation. This article ...
