NOx gases react to form smog and acid rain as well as being central to the formation of fine particles (PM) and ground level ozone, both of which are associated with adverse health effects.. NOx is produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures.In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution can be significant.Ox gases react to form smog and acid rain as well as being central to the formation of fine particles (PM) and ground level ozone, both of which are associated with adverse health effects..

Eastern gray squirrels eat a range of foods, such as tree bark, tree buds, berries, many types of seeds and acorns, walnuts, and other nuts, and some types of fungi found in the forests, including fly agaric mushrooms (Amanita muscaria).ciurus carolinensis, common name eastern gray squirrel or grey squirrel depending on region, is a tree squirrel in the genus Sciurus. It is native to eastern North America, but has since been introduced to European regions.
Gray squirrels predominantly feed on tree nuts, but will also eat flowers, seeds, fungi, insects and even the occasional bird eggs. In addition to serving as an important prey species, the nut storing tendencies of the gray squirrel help to disperse tree seeds within their habitat.hese small, tree-dwelling rodents fit easily into a number of habitats due to their remarkable adaptability. Gray squirrels are easily recognized by their gray coat (varying from yellowish gray to pure silver, though different color morphs exist), ruffed tail and cream-colored underbelly.
