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).

In India huge amount of flyash is generated from coal-fired thermal power plants, causing several disposal-related problems. The disposal of coal ash is a matter of great concern nowadays as it requires huge area of land at the disposal site but also adversely affects surface, sub surface environment. The present paper discusses the several environmental aspects of coal ash disposal.

Air pollution tolerance index (APTI) is used to select plant species tolerant to air pollution. Four physiological and biochemical parameters, namely: leaf extract pH, ascorbic acid, total chlorophyll and relative water content were combined together in a formulation signifying the APTI of plants.

Three key polutants, namely RSPM, SO2 and NO2 have been measured in schools in the National Capital Region (Delhi). Monitoring was conducted at all the 5 locations. Alarming levels of pollutants were reached on Diwali day, a festival of lights and for days preceding Diwali at all the locations.

Rapidly growing cities, higher traffic load, reliance on outdated industrial processes, growing energy consumption, lack of appropriate industrial zoning and environmental regulations and poor implementation of control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.

No extensive study has been made in the context of Indian Iron and Steel Industries attempting to measure the intensity of industrial pollution in the field of environmental management and to identify the different environmental indicators for making the units proactive.

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.

We undertook an economic valuation of mangrove forests in Balochistan province of Pakistan drawing on primary data from a survey of 80 households depending on mangrove forests. It was found that the direct value of mangroves was USD 1,287 per hectare, while the total value for the village was calculated to be USD 4,419,935.

The present laboratory study reports the results of various engineering properties, such as compressive strength, tensile strength, flexural strength and impact strength of fibre reinforced concrete produced from waste plastic fibres and flyash which are the two environmental pollutants.

Remote sensing is a direct adjunct to field, recently playing an important role in the study and assess the natural resource in any part of the world. In this view the present work has been taken upto study and assess the natural resources and environmental potential in and around Rajampet of Kadapa district, Andhra Pradesh.
