Air pollution  is a mixture of solid particles and gases in the  air . Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of  air pollution  in cities. When ozone forms  air pollution , it's also called smog. Air pollution  causes damage to crops, animals, forests, and bodies of water. It also contributes to the depletion of the ozone layer, which protects the Earth from the sun's UV rays. ... Some of the other environmental effects of  air pollution  are haze, eutrophication, and global climate change. The possible mechanism by which fine particulate air pollution may increase the risk of cardiovascular disease include o     An increase in mean resting arterial blood pressure through an increase in sympathetic tone and/or the modulation of basal systemic vascular tone. o     An increase in the likelihood of intravascula...

The enteric nervous system: a second brain AND NOW,THE RESEARCH Reveals that our skin is acting as 3rd.Brain. There is extensive evidence that multiple sensory systems are functionally expressed in epidermal  keratinocytes, together with a range of  neurotransmitters and their receptors.  Epidermal keratinocytes also secrete multiple bioactive molecules with the potential to influence whole-body physiology and emotional state. Thus, the epidermis appears to have the functional systems required for reception of environmental information from  sensory organs, processing of that information, and transmission of it to the systems of the whole body.   In other words, the epidermis, like the brain, has the capability to act as an interface between the body and the environment .  Although much further research is needed to validate the idea that the epidermis serves as a “third brain”, this concept is an exciting one, opening up new vistas f...
