  Air pollution is increasing and air quality in Delhi is deteriorating each year. The Indian capital is one of the most polluted cities in the world, with carcinogenic chemicals, nitrogen dioxide, and sulphur dioxide being emitted from vehicles and industry — these pollutants cause diseases including asthma, lung cancer, and even heart attacks. The World Health Organization (WHO) has labeled the city’s air quality as “very unhealthy” for days that are not windy. This means that it is worse than the pollution levels in Beijing, China, or Tehran, Iran, which were once designated as the world’s worst cities for air quality. According to a new study (The Air Quality Life Index® & The Delhi Pollution Control Committee (DPCC), the air pollution in Delhi could lead to ten years of life lost in the next two decades, and that’s not even counting the damage done on account of burning rich fuel. Millions of people are exposed to unhealthy levels of pollution every day which causes respir...

  The ripening of fleshy fruits represents the unique harmonization of developmental and biochemical pathways leading to changes in color, texture, aroma, and high nutritional qualities. The gaseous plant hormone ethylene (natural ripening agent in fruits and vegetables) is also an important contributor of nutrition and fiber to the diets of humans. Some fruits and vegetables are more sensitive to ethylene than others, and often they tend to be kept separately. Ethylene  is one of the newest gases being used in fruit and vegetable storage. It is a gas that is released when ripe or damaged fruit is stored. The recommended practice in fruits and vegetable warehouses is to keep ethylene producing items separately from non producing items. Even a small amount of ethylene gas leakage during shipping and storage will accelerate the process of the decay of fresh items. Further, some of the storage providers will use the gases like nitrogen and  sulphur gas  to hamper the hi...
