Factors that can decrease or increase air pollution
Answers
Answer:
Factors that decrease air pollution :
*Firstly ,we have to stop the high usage of automobiles (vechiles ) which can result in the mixing of harmful gases in the air.
*Some measures should be taken by factory and industries owners in the realising of chemical gases into the air
*Especially everyone has 2 raise a hand to stop globalisation which results in the emission of a powerful gas known as methane. ..

Explanation:
Air pollution is composed of a complex mixture of substances that have well characterized adverse effects on health. Perhaps one of the best known examples of air pollution increasing morbidity and mortality is the 1952 London Smog.1 Weather conditions at the time caused a sharp increase in ambient air pollution levels and over the following few days, more than three times as many people died as would otherwise have been expected. A great deal has changed since that incident with guidelines and legislation restricting pollution levels in many regions of the world to well below the levels in the 1950's.2 Despite that, major concerns over more long-term effects of pollution remain. A number of contemporary studies have shown that air pollution can account for 1–2 years of life shortening in those exposed to higher concentrations.3
In this review we discuss whether air pollution could contribute to intestinal disease. We focus mainly on urban air pollution, as opposed to pollutants in food or indoor air pollution (e.g., cigarette smoke), although these can also lead to intestinal pathology. First, we present current data on effects of air pollution on various health conditions and then discuss the relevance of pollution to intestinal physiology and disease, with specific focus on inflammatory bowel diseases (IBD). Various components within pollution that could cause these effects are then presented and potential mechanisms of action are suggested.
2 Systemic Effects of Air Pollution in Humans
On a population basis, large-scale case-crossover studies have shown increased hospitalizations and mortality during and immediately following increased air pollution levels (reviewed in Ref. 4). Notably, increased levels of air pollution cause decreased lung function in healthy individuals,5 impaired lung function growth in exposed children 6 and exacerbations of existing lung diseases (e.g., chronic obstructive pulmonary disease, asthma).7 Less intuitively, many studies have also shown that one component of air pollution, particulate matter (PM), is consistently associated with increased cardiovascular mortality (reviewed in Ref. 8). With such widespread and significant health effects, it would not be surprising to find that the bowel is affected by air pollution; however, there is very little research targeted specifically at this topic.
