Plants that clean your Home

Common day household activities release harmful toxins into our indoor environment. But indoor plants may provide a valuable weapon in the fight against rising levels of air pollution in the home. Such plants are not only decorative, but are surprisingly useful in absorbing potentially harmful gases and cleaning the air inside modern buildings. Studies generated at NASA recommend that you use 15 to 18 good-sized houseplants in 6 to 8 inch diameter containers to improve air quality in an average 1,800 square foot house. The more vigorously they grow the better job they'll do in improving the air quality in your homes.

Learn it from the insects

The essay urges you to develop skills in recognising organisms whose survival is intrinsically linked to the quality of water. Conversely you can gauge the quality of the surface water through a cursory inspection.

India’s air quality information classified

New Delhi, 10 Jan (GnY News Service): The air quality in the cities in India is worsening but the Central Pollution Control Board (CPCB) and the various other governmental institutions that duplicate their work do not wish to share their findings with the general public - it seems that the data is classified. With no real time data on the website of CPCB that mans around 500 air quality stations all over the nation, manual and automatic, it is impossible to update oneself with the air quality of the city...

Managing India’s Hazardous Wastes

The growing economy along with emerging industries generates hazardous waste which if not managed can pose to be a serious health hazard. Various strategies put forward by the Ministry of Environment and Forests in terms of regulatory and institutional framework, technical guidelines, identification, treatment and disposal to manage such waste are in place, but they require effective implementations.

Predicting Poor Air Quality Events

Air pollution is a growing problem in India. Factories, power plants, automobiles and dust, smoke from bush fires and volcanic eruptions are responsible for pollution. The deterioration of air quality thus results into a corresponding increase in health problems, eventually inducing the monitoring of air quality and its prediction as a prime necessity in day-to-day life.

Calculating Carbon Uptake by the Oceans

Nitrogen-15 is an isotope that is useful in determining how much of the anthropogenic carbon dumped in the atmosphere is taken up by the oceans. Our efforts in the Indian Ocean to determine this rate is outlined here.

Contaminated Drinking Water

Water availability in India is constantly decreasing and is under threat due to the increasing levels of pollution. Out of nearly 17 lakh rural habitations in the country, only 5 lakh have access to safe drinking water supply through pipes in 2013.

CNG and Pollution

With 1.1 million vehicles running on compressed natural gas (CNG), India has the 5th largest fleet of CNG vehicles in the world. However, CNG use only manages to reduce the particulate matter (PM) emissions as compared to other conventional fuels—on other counts however it performs poorly. Combined with the inability of the massive population of two-stroke auto rickshaw engines to adequately burn CNG, beseeches the government to re-evaluate their transport pollution control strategy.

Unfit for Use

India’s urban areas generate 45000 litres of waste water per day while municipalities have the capacity to treat only 26 per cent.

PM2.5 Vs PM10

The problematic particles are 2.5 micrometers or less in diameter, not 10, which result in health deficits. In developing countries, there is a lack of surface- based air pollution sensors which make it difficult to assess the extent of particulate pollution. NASA’s study on information obtained by MODIS and MISR-AOD satellites suggested that 80 per cent of the world’s population breathes air with a pollution level above WHO’s recommended level of 10 micrograms.
