Increasing Vehicular population and deteriorating quality of air is the by-product of rapid growth of population and haphazard urbanization in India. The urban population in India has increased significantly from 62 million in 1951 to 285 million in 2001 and is estimated to grow to 540 million by the year 2021. In terms of percentage of total population, the urban population has gone up from 17% in 1951 to 29% in 2001 and is expected to increase up to around 37% by the year 2021. About 55 million vehicles were playing on Indian roads in 2001.
On December 1, 2014, COMARNAT, the national regulatory committee of the Secretariat of Environment and Natural Resources (SEMARNAT), approved a proposed update by
SEMARNAT to existing emissions standards regulating particulate matter (PM), nitrogen oxides (NOX), hydrocarbons (HC) and carbon monoxide (CO) from heavy-duty diesel
BHUBANESWAR: Notwithstanding a state government directive of June 25, 2013, against setting up brick kilns on river beds, 23 such units were found operating in Khurda and Puri districts.
The aim of this study is to analyse the amount of atmospheric pollution caused by vehicular traffic and the public strike, during which vehicular traffic is highly curtailed, offers an excellent opportunity for our purpose. The present study is carried out through systematic in situ measurements of particulate matter (PM), black carbon (BC) and carbon monoxide (CO) over the urban region of Hyderabad, India during two public strikes on 24 December 2009 and 18-21 January 2010.
This study establishes a baseline inventory of the number, types, and approximate distribution of DG sets in use in the Kathmandu Valley of Nepal and estimates air pollution emissions, including black carbon, from these generators.
Rising temperatures because of increased emissions of long-lived greenhouse gases (LLGHGs) have had and will continue to have significant negative impacts on crop yields. However, other climate changes caused by short-lived climate pollutants (SLCPs) are also significant for agricultural productivity. The SLCPs black carbon and ozone impact temperature, precipitation, radiation, and—in the case of ozone—are directly toxic to plants.
China’s largely unregulated ports and shipping system generate significant air pollution that imposes a huge health and environmental burden and contributes to the country’s over 1 million pollution-related deaths each year, according to a new report released by the Natural Resources Defense Council (NRDC).
