The Global Air Pollution Crisis

Across the globe, people are suffocating in bouts of dense smog and extremely high levels of air pollution. Just about every country in the world grapples with pollution, no matter how rich or poor they are. But you may not be aware of just how toxic your country is.

Importance of National Ambient Air Quality Standards

Air Pollutant includes any substance in solid, liquid or gaseous form present in the atmosphere in concentrations which may tend to be injurious to all living creatures, property and environment. Various contaminants in different forms from both man-made and natural sources perpetually enter our environment and contaminate it causing toxicity, diseases and environmental decay. Recent industrialization and increased number of potent air polluting sources like automobiles, landfills, etc. has gushed into the atmosphere toxic materials which not only harm human40

Why AAP Government’s Odd-Even Car Formula is Good for the Environment

India is the seventh largest country in the world and almost 30% of its population resides in the urban areas according to the 2011 census. The decreasing viability of the agricultural sector and increasing employment opportunities in the cities has led to urban expansion, which has brought about an increase in the movement of goods and services which in turn are usually propelled by fossil fuels. The increasing GDP is a great sign but what the GDP doesn’t include is40

Houseplants – Nemesis For Indoor Air Pollution

The energy crunch witnessed by the world in the late 1970s forced people to design and resort to energy efficient techniques and practices, which also included energy efficient buildings. Energy efficient housings brought in the trend of buildings which were super-insulated and had reduced free exchange of fresh air. It was eventually realized that these buildings having tighter and congested construction, sealed from outside air was more prone to accumulation of indoor air pollutants to dangerous levels, greatly affecting the40

Vehicular Pollution and Emission Standards in India

Vehicle emission norms were set for the first time in 1990’s when the government under the Supreme Court order introduced Euro norms in 1999. Later, it was replaced by Bharat Stage Emission standards. Under the Bharat Stage IV norms which are in turn based on Euro IV norms, Bharat Stage-IV , CO should be 1.0 (g/km) and HC+NOx (g/km) should be 0.18 (combined)1 as per CPCB. The implementation has however suffered from certain limitations such as the need for retro40

Ability of Honeybees to Find the Flowers Affected by Diesel Exhaust: Research

The researchers at the University of Southampton, in the first week of October 2013 revealed that the ability of honeybees to find the flowers can be hindered by the chemical in diesel exhaust. The tests revealed that the diesel exhaust degraded the floral scent chemicals on which the honey bees foraged. The study revealed that the specific group of chemicals found in diesel exhaust, known as NOx was responsible for diminishing the response of insects towards the floral scents. The40
