Messing with the monsoon: Study: Manmade aerosols can alter rainfall in the world’s most populous region
Original story at MIT On the Indian subcontinent, the widespread burning of firewood, coal, agricultural waste, and biomass for energy disperses black carbon particulates into the atmosphere. These manmade aerosols not only pollute the air, but also form an “atmospheric brown cloud” that’s disrupting the local climate. A case in point is the South Asian summer monsoon, a ...

Aerosol characteristics at a continental urban station in southern India
Spectral Aerosol Optical Depth (AOD), Black Carbon (BC) mass concentration and Suspended Particulate Matter (SPM) measurements were made at an urban continental location, Bangalore (13°N, 77.6°E), in southern India. These results show that AODs reach a maximum during April (∼0.5) and minimum during December (∼0.2) at 500 nm. BC and SPM showed variations of 0.6-4.2 μg m³ and 120-195 μg m³, ...

In-Vehicle exposures to particulate matter and black carbon
ABSTRACTIn-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal totalexposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 times a ...

How Does Air Pollution Affect Biodiversity?
Biodiversity, the multitude of life forms on Earth, forms an intricate web of interdependence that sustains ecosystems and human existence. It’s not just a collection of species but a complex network of ecological processes that maintain the balance of nature. However, this delicate balance is under siege by a human-made phenomenon – air pollution. The Connection Between ...

What are we doing to our children’s brains?
Environmental chemicals are wreaking havoc to last a lifetime The numbers are startling. According to the U.S. Centers for Disease Control and Prevention, about 1.8 million more children in the U.S. were diagnosed with developmental disabilities between 2006 and 2008 than a decade earlier. During this time, the prevalence of autism climbed nearly 300 percent, while that of attention deficit ...
