Which of the following pollutants have adverse implications for human health as well as climate change? (A) Nitrogen dioxide (B) Particulate matter (PM 2.5) (C) Ozone (D) Methane (E) Nitrous oxide Choose the correct answer from the options given below : Correct Answer (B) and (C) only

Pollutants with the strongest evidence for public health concern include particulate matter (PM), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2) and sulphur dioxide (SO2). Health problems can occur as a result of both short- and long-term exposure to these various pollutants. For some pollutants, there are no thresholds below which adverse effects do not occur. 

Important PointsParticulate matter (PM):

  • Particulate matter is a term used to describe inhalable particles that are made up of sulphate, nitrates, ammonia, sodium chloride, black carbon, mineral dust, or water.
  • PM is capable of penetrating deep into the lung and entering the bloodstream, where it can cause cardiovascular (ischemic heart disease), cerebrovascular (stroke), and respiratory effects.
  • Long-term and short-term particulate matter exposure is linked to morbidity and mortality from cardiovascular and respiratory diseases.

Ozone:

  • Ground-level ozone is a significant contributor to smog.
  • It is formed as a result of photochemical reactions with pollutants such as nitrogen oxides (NOx) emitted by vehicles and industry.
  • Because of the photochemical nature of ozone, the highest levels are observed during periods of sunny weather.
  • Excessive ozone exposure can cause breathing difficulties, trigger asthma attacks, reduce lung function, and lead to lung disease.

Additional Information

  • Nitrogen dioxide is a strong oxidant that is soluble in water and reddish-brown in colour. NO2 is produced by combustion processes such as those used in heating, transportation, and power generation.
  • Methane is a significant greenhouse gas. It aids in the formation of ozone. Incomplete combustion of biomass, biofuel and fossil fuels in simple stoves, open fires, or wick lamps emits methane.
  • Carbon monoxide is a toxic gas that is colourless, odourless, and tasteless and is produced by the incomplete combustion of carbonaceous fuels such as wood, gasoline, charcoal, natural gas, and kerosene. 

Therefore, the correct answer is Particulate matter 2.5 and Ozone as they two have adverse health effects compared to other pollutants.

We have forgotten that health really means to enable a person to do his work and do it well. A lot of modern medicine, and this includes many patients as well as many physicians, pay very little attention to health but very much attention to those who imagine they are ill. Our great concern with health is shown by the medical columns in newspapers, the health articles in popular magazines and the popularity of television programmes and all those books on medicine. We talk about health all the time. Yet for the most part the only result is more people with imaginary illness. A healthy man should not be wasting time talking about health : he should be using health for work.

A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given fouralternatives. Teaching about compassion and empathy in schools can help deal with problems of climate change and environmental degradation,” says Barbara Maas, secretary,
Standing Committee for Environment and Conservation, International Buddhist Confederation (IBC). She was in New Delhi to participate in the IBCs governing
council meeting, December 10-11, 2017. “We started an awareness campaign in the year 2005-2006 with H H The Dalai Lama when we learnt that tiger skins were
being traded in China and Tibet. At that time, I was not a Buddhist; I wrote to the Dalai Lama asking him to say that this is harmful and he wrote back to say, “We
will stop this.” He used very strong words during the Kalachakra in 2006, when he said, If he sees people wearing fur and skins, he doesnt feel like living. This sent
huge shock waves in the Himalayan community. Within six months, in Lhasa, people ripped the fur trim of their tubba, the traditional Tibetan dress. The messenger was ideal and the audience was receptive,” says Maas who is a conservationist. She has studied the battered foxs behavioral ecology in Serengeti,Africa. She heads the endangered species conservation at the Nature and Biodiversity Conservation Union (NABU) International Foundation for Nature, Berlin. “I met Samdhong Rinpoche, The Karmapa, HH the Dalai Lama and Geshe Lhakdor and I thought, if by being a Buddhist, you become like this, I am going for it, “says Maas, who led the IBC initiative for including the Buddhist perspective to the global discourse on climate change by presenting the statement, The Time to Act is Now: a Buddhist Declaration on Climate Change, at COP21 in Paris. “It was for the first time in the history of Buddhism that leaders of different sanghas came together to take a stand on anything! The statement lists a couple of important things: the first is that we amass things that we dont need; there is overpopulation; we need to live with contentment and deal with each other and the environment with love and compassion,” elaborates Maas. She is an ardent advocate of a vegan diet because “consuming meat and milk globally contributes more to climate change than all "transport in the world.” Turning vegetarian or vegan usually requires complete change of perspective before one gives up eating their favorite food. What are the Buddhist ways to bringabout this kind of change at the individual level? “To change our behavior, Buddhism is an ideal vehicle; it made me a more contented person,” says Maas, who grewup in Germany, as a sausage chomping, meat-loving individual. She says, “If I can change, so can anybody”. According to the passage, how can studying compassion and empathy in schools help?
In this question, a passage and a statement related to it have been given. Read carefully the verse and review the statement based on it. Delhi, which is one of India's capital an d one of the largest cities in the world, is undergoing severe crisis, due to its high level of urbanization, increasing population and high levels of pollution. Studies have proven that Are the biggest factors of pollution used for industrial and domestic use? And due to their use, people here emit large quantities of nitrogen oxides (NOx), ozone (O3), black carbon (BC) and microorganisms (PM). According to the 2015 Global Burden of Disease report, there were 1.09 million deaths due to PM 2.5 in India. Air pollution was included as one of the 10 biggest threats to health. According to the World Health Organization, 37 cities of India are among 100 worst polluted cities in the world, where PM10 was found to be the highest ever. For the production of ozone, together with sunlight and heat, nitrogen oxides (NOx) and organic compounds (VOCs) are needed simultaneously. Therefore, in the summer months, ozone is produced in large quantities in the cities. Statement: Air pollution is one of the top 10 factors affecting health in India. Select the most suitable from the following options A-statement is absolutely true B-statement is probably true C-statement can not be reviewed D-statement is completely false
