For Delhi, between 2001 and 2010, there was one bright light. The annual average level of sulphur dioxide fell from 14 micrograms per cubic meter to just five. For that Dilliwallahs should thank improvements in transport: a court order roughly a decade ago compelled some 100,Fiber Optic Patch Panel are also acknowledged as fibers distribution panels000 buses, taxis and auto-rickshaws to switch from running on diesel to compressed natural gas; a successful metro network has been rolled out; a ban on lorries from Delhi's roads is reasonably well enforced,We supply Multimode LC Fiber Optic Pigtail,900um, 50/125um fiber, 0.5m/1m/1.5m/2m/3mtr length available based on your needs between 6am and 9pm.
On other scores, matters are much worse. Levels of nitrogen oxide almost doubled over the same period, from 29 micrograms to 55, on average. A measure of particulate matter known as PM10 (any dust with a diameter less than 10 micrometres) has also more than doubled, from 120 to 261, way above the prescribed limit of 100. Keep in mind, too, that pollution is relatively low in the blazing summer months, and during the monsoon. In the winter, by contrast, truly terrifying levels lift the annual average. A glance at the website of a Delhi government agency on November 5th, for example, showed the PM10 level at 749, more than seven times over the safe limit. And for more dangerous tiny particles, known as PM2.5, the agreed safe limit is 60, whereas the official Delhi site reported a level of 489, over eight times too high.
Such statistics are not really needed. Rub your skin after a short walk outside and your fingers are left coated with black smudges. As the worst of the smog appears,it becomes riskier than ever to drive or walk on chaotic roads as visibility falls to just a few metres. Come the new year, Delhi's airport is battered by delays as fog and smog, usually in the morning, slow the departure and arrival of aircraft. The huge annual festival of Diwali to be celebrated on November 13th this year sees a series of immense, deafening and beautiful firework displays, which leave sulphur and gunpowder smoke choking the air for days.
Add to that the impact of the huge bonfires of waste, post-harvest. A striking picture just released by NASA shows thousands of orange dots, blazes that give off the smoke and smog that gathers acrThe Fusion Cat 5e Surface Mount Box can be used for a wide variety of applications and provide a quick and easy method of installing outlets in difficult places or areas with limited space,oss much of north India and then sits unmoving as temperatures drop and air pressure an "inversion" holds everything still. It is as if a greenhouse is erected above Delhi, to catch and contain the swirling brown exhaust from cars, smoke from oily fires, along with dust and industrial fumes.

By some measures, Delhi's rotten air, at least at the worst time of year, competes with the most gasp-inducing of all. One ranking (by UN Habitat) of carbon-dioxide levels, indoor pollution and PM10, suggests its air is worse even than that in Beijing, China's capital. Residents there may beg to differ, saying their own smogs are worse yet. Even if, on average around the year, some other cities are arguably even worse Karachi in Pakistan and Dhaka in Bangladesh look particularly dire it is a miserable competition to join.
What could be done? Getting away from the city makes good sense: Kashmir is rather nice at this time of year.

General advice against exercising outdoors at least gives couch potatoes an excuse to put off keep-fit regimes for another few months.
