Abstract—Tourism in itself is a significant contributor to greenhouse emission, transport pollution, degradation of land, addition of solid and sewage waste and colossal ill effects on health of indigenous people. The tourist thus, though a pivotal attraction to the economy, simultaneously becomes its destructor. The study concerning PM 2.5 and PM 10 along with humidity level was conducted in early winter of 2015 to July, 2016 in and around new Delhi, a heritage city attracting innumerable tourist. the Present study has given a clear indication of correlation of both outdoor as well as indoor air pollution viz-a-viz human health. Both tourists and local residents frequent tourist places exposing themselves to particulate matter increasing their vulnerability to respiratory irritations (38%), headaches (24%), asthma (19%), irritable behavior (12%), Irritable Bowel Syndromes (9%). This fact is also supported by a data study projected by W.H.O. that attributes every 8th death in the world to air pollution. This paper deals with the aforesaid aspects, shortfalls in the enviro-legal framework of india embodied in the Air (Prevention and Control of Pollution) Act, 1981 and its execution to suggest methods to improve or remedy the situation have also been explored. Index Terms—Air pollution, tourism, environment, India, particulate matter I. INTRODUCTION India being a developing country and an emerging economy has ancient cultural heritage attracts a huge number of tourists, on the other hand, tourism itself is a significant contributor to greenhouse gas emissions, transport pollution and waste generation. This paper deals with the evaluation of air pollution and its impact on human health as well as to explore the implementation of air pollution laws and suggested how to avoid pollution due to tourism and tourists from pollution. According to WHO, Delhi the capital of India was named as the worst for PM2.5 particles out of 1600 cities around the world with the value of 153 micrograms per cubic metre [1]. The study concerning PM 2.5 and PM 10 along with the humidity levels was conducted in the early winter of 2015 to June 2016 in and around the areas of Delhi. PM refers to the particulate matter consisting of solid particles and liquid droplets in the air. It is formed from the chemical reaction in the atmosphere and through fuel combustion like motor vehicles, industrial facilities, residential fireplaces, Manuscript received July 12, 2016; revised October 28, 2016.

Tourism world over has been recognized as a major contributor of economy. It holds 4 th largest industry contributing to world‟s economy and for a developing nation like India tourism is one of the major service sectors, growing with leaps and bounds by every passing year and has risen in its contribution from 2.2% (2014) to estimated 7.6% (2015) to nation‟s GDP [3]. Tourism upholds both negative and positive impact on nation‟s economy. The ill effects of it are addition of pollution, overutilization of resources like energy and food, undesirable social and cultural changes, adverse impact on environment and ecology, depletion of valuable resources like fuel and water, threat to the wildlife owing to the disturbances in their habitats, degradation of land, addition of solid and sewage waste etc and over all is that it coasts the health of localities or indigenous people along with visitors. Increasing tourism means increasing air pollution which gives us instantaneous repercussions like poor visibility leading to more accidents, poor productivity of plants, higher concentration of PM2.5UM hampers respiratory and circulatory efficiencies of animals, higher troposphere ozone, a strong oxidizing agent, decline plants productivity along with their premature deaths. Oxides of nitrogen and sulphur, main pollutants from vehicular pollution, deteriorate water and soil chemistry. Excessive nitrogen depositions pose threat to the very existence of aquatic ecosystems by accelerating eutrophication. In general too air quality in most of the cities is deteriorating at an alarming rate, primarily due to increasing vehicular fleet [4]. Ground level Ozone, a secondary pollutant and one of the green house gases, if inhaled can lead to asthma, chest pain, coughing, throat irritation, congestion etc. The ill effects of ozone are worst during hot summer days while the particulate contamination is equally dangerous in all seasons [5], [6]. Delhi, the medieval capital of the country has today grown into a sprawling metropolis which today serves not only as the center of political activity of the country but also the center of trade and commerce in the Northern half of the country making it an island of opportunity which attracts many a migrants from distant parts of the country. Most recently the city has been battling the problem of pollution which has exacerbated since the late 1990‟s owing to the increase in vehicular traffic and rapid industrialization. According to government agencies Delhi‟s air pollution will impact tourism and is trying to make great efforts to make the city pollution free [7]. II.
