Solid waste management in Patna – analyses of ambient air and ground water pollution
Municipal Solid Waste (MSW) in Patna is disposed of in an unscientific manner without considering environmental impacts. The wastes are dumped in the low-lying areas without compliance of the MSWM Rules, 2000. The dumped wastes are mixed with biomedical wastes making it hazardous. Ambient air quality and ground water were analysed at two dump sites to study the possible impacts of MSW. The ...

Study of vehicular emissions with reference to Pakistan's National Environmental Quality Standards: case study of District Swat, North of Pakistan
This study was conducted during 2011–2012 with the objective to assess the ambient air quality in the surroundings of a newly constructed road in relation to Pakistan's Environmental Quality Standard (Pak–NEQS). The area was monitored twice, before and during the construction, to determine levels of sulphur dioxide, nitrous oxide, carbon monoxide, and PM10 (particulate matter). A ...

SO2 NAAQS Implementation: The Great American Update
Since the 1-hour sulfur dioxide (SO2) National Ambient Air Quality Standard (NAAQS) became effective in August 2010, ALL4 has been tracking it every step of the way. Its implementation has proven to be chaotic at times and quiet at others. As we are ramping up into our air regulatory reporting obligations for 2014, U.S. EPA’s implementation of the 1-hour NAAQS is ramping up as well. This ...

U.S. EPA Convenes RSL Modelers Workshop
On May 10 - 13, U.S. EPA met with regional, state, and local modelers in Portland, Oregon for the U.S. EPA Regional/State/Local (RSL) Modelers Workshop. Several “hot-topic” items were included on the agenda, most notably, the new NO2 and SO2 National Ambient Air Quality Standards (NAAQS). The regulated community was anticipating that further guidance related to Significant Impact ...

Crazy sulphur dioxide needs gentle sulphur dioxide sensor to appease
Background- The most important corrosive gas in the atmosphere is SO2, which accelerates the corrosion process of most metals. My country is the largest coal producer and consumer in the world. SO2 pollution is very serious. In some areas, the SO2 content in the atmosphere exceeds that of the environment. 60% of capacity. Therefore, for SO2 monitoring we will use accurate and sensitive ...

Hydroxyl Radical Eliminates H2S in Wet Scrubbers & Flue Gases
In a recent study in Houston, TX, H2S was removed from a natural gas stream containing 2,000 mg/l of H2S and 5% CO2 using JC 9450 ROS. JC 9450 ROS is a new mineral oxychloride compound that generates Reactive Oxygen Species (ROS) like hydroxyl radical ions and others in a highly soluble form that is easy to use. The study, which simulated operating conditions of a wet scrubber, found that the ...

EPA establishes new 1-hour standard for sulfur dioxide
On June 2, 2010, the U.S. EPA established a new 1-hour primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). The new 1-hour standard was set at the level of 75 parts per billion (ppb) calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations. With the establishment of the new 1-hour SO2 standard, ...

SO2 Monitoring
SO2 monitoring is an efficient way to detect and reduce exposure to sulfur oxides which further benefits in reducing the formation of particulate sulfur pollutants like fine sulfate particles, acid rain, and smog. This article covers information on sulfur oxides, their sources, permissible levels in the ambient air, health and environmental impact, possible corrective measures, the need for ...

States propose attainment designations for the new 1-hour So2 NAAQS
The U.S. EPA revised the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2) on June 2, 2010 by implementing a new 1-hour standard of 75 parts per billion (ppb) (calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations). Based on an evaluation of the risks posed by acute exposure to SO2, EPA ...
