Based on its review of the air quality criteria and the national ambient air quality standards (NAAQS) for carbon monoxide (CO), EPA is proposing to retain the current standards. EPA is also proposing changes to the ambient air monitoring requirements for CO including those related to network design.

This new synthesis report provides outcome of the Air Quality Monitoring, Emission Inventory and Source Apportionment Study carried out in the cities of Bangalore, Chennai, Delhi, Kanpur, Mumbai and Pune. The primary focus of the study was on respirable particulate matter (PM10), although it also deals with other pollutants like NOx, SO2, Ozone (O3), PM2.5, etc.

Environmental Impact Assessment (EIA) report is intended to renew the mining lease of Bhatin Mine. The lease area of Bhatin Mine is 142.98 ha under village of Bhatin which is part of contiguous lease of Jaduguda & Bhatin complex of 531.21 ha (1312.62 acres). However these mines are being separated by distance of about 4 km and having separate mines plan.

Total suspended particulate matter (TSPM) and respiratory particulate matter (PM10) are the main air pollutants in ambient air of opencast coal projects (OCPs). The present paper focuses on the ambeint air quality analysis for the 5 opencast coal projects scattered around Wardha Valley, namely Durgapur, Padampur, Gughus, Sasti, Hindustan Lalpet Mines of Western Coalfields Limited (WCL).

Rapidly growing cities, higher traffic load, reliance on outdated industrial processes, growing energy consumption, lack of appropriate industrial zoning and environmental regulations and poor implementation of control measures have all contributed to reduced aur quality.

Concentrations of water soluble ions (Na, K, Ca and Mg) in PM10 alongwith gaseous pollutants (NO2 and SO2) were measured during summer season of 2009. The sampling site is located near National Highway which is a high traffic density site.

Tirupur: It turned out to be a noisy and polluted Deepavali in Tirupur city this year.

This was revealed in the ambient air quality and noise pollution surveys conducted by the District Environmental Laboratory (DEL) of the Tamil Nadu Pollution Control Board here during the Deepavali day and on the day prior to it.

Pollution control strategies for attainment of particulate standards must be able to provide convincing evidence that the relative importance of emission sources is understood and that the control programmes proposed are cost-effective and can be adopted by the community with confidence.

Computer scientists from Viterbi School of Engineering, University of Southern California, USA, launched software that uses the sky’s pictures to test air quality. Sameera Poduri, who worked on the project, explained the technology in this interview to Down To Earth.

New Delhi: The fog has made an early appearance this year. Thursday morning saw shallow fog in some parts of the city, specially around IGI Airport.
