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, ...

Monte-Carlo model of a gas analyser operating under EN 14181:2014 to investigate achievable uncertainty during emission monitoring
Monitoring of emissions is controlled by the Industrial Emissions Directive (IED), which sets out the requirements for emitters to meet. There are standards in place that, when followed, allow the operators to meet the IED requirements. One of these, EN14181:2014, setting out the quality assurance requirements for continuous emission monitoring, has recently been revised. It is assumed that any ...

India: ENVEA Selected for Expanding Air Quality Monitoring Network in Maharashtra State - Case Study
In January 2019, the Ministry of Environment, Forest and Climate Change (MoEFCC) of India launched the National Clean Air Programme (NCAP). It’s been designed to prepare action plans with an objective to reduce PM2.5 pollution by 20–30% by 2024 as compared to 2017, in 122 million plus cities. The NCAP designated 122 cities as non-attainment from 21 states and 2 ...

Air pollution monitoring: a solution for cost effective measurements - Case study
Air pollution is one of the main environmental problems to be addressed by cities worldwide. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO, SO2 and NOx) concentrations in ambient air. Many cities are not able of meeting ...

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 ...

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 ...

Case Series: FPI Offers Its Solution for Vietnam Environment Monitoring
Poor air quality threatens the health of millions of people worldwide, but more so for individuals living in Vietnam. Air pollution causes nearly 60,000 deaths yearly in Vietnam. According to Statista, the country's population-weighted concentration of particle pollution (PM) stood at 20.4 micrograms per cubic meter in 2019. That's close to the recommended maximum concentration of 25 micrograms ...

TRS Monitoring in the Pulp Industry
The smell associated with pulp production originates from different sulfur compounds. The most well-known is probably hydrogen sulfide, H2S (H-S-H) but there are also compounds like methyl mercaptan (CH3-S-H), dimethyl sulfide (CH3-S-CH3), and dimethyl disulfide (CH3-S-S-CH3). These four substances are collectively referred to as “total reduced sulfur”, TRS. Emissions of TRS together ...
