VOC composition and ozone-forming potential of the exhaust gas of in-use motorcycles
The emission profile of volatile organic compounds (VOC) and the ozone-forming potential (OP) of the exhaust gas of six in-use motorcycles (four 4-stroke- and two 2-stroke-engines) were determined. The motorcycles were tested on a chassis dynamometer in a real-world driving cycle. The analysis involved the C2–C12-hydrocarbons as well as the aldehydes and ketones. Additionally, the regulated THC ...

Vertical distribution of VOCs and ozone observed in suburban North Carolina
As a continuing effort by the State of North Carolina to develop a State Implementation Plan for ozone control in the Raleigh Metropolitan Statistical Area, vertical measurements of C2–C10 hydrocarbons and ozone are made on a 610 meter multi-communications tower. Results signify that both long-range transport from fossil fuel combustion, petroleum exploration, petroleum refineries, and geogenic ...

Potential of biofiltration for VOCs emission control and safety aspects
Directive 99/13/EC on the emission of Volatile Organic Compounds (VOCs) is impacting on several industries in Italy, as well in other EU countries. Many small enterprises have to invest in new control systems and need to be helped to choose an appropriate and safe technology. As VOCs are highly flammable compounds, high concentrations in emission flows can pose a fire and explosion hazard if ...

Uncertainties in current knowledge of atmospheric trace gases associated with US agriculture
Approximately 80 different crop species are grown in the United States in widely differing geographic areas, climatic and edaphic conditions, and management practices. Although the majority of cultivated acreage in the United States is planted with only about 10 primary crops, uncertainties associated with trace gas emissions arise from: (1) limited data availability, (2) inaccurate estimates ...

Does emissions trading lead to air pollution hot spots? Evidence from an urban ozone control programme
This study is an empirical investigation into the contentious issue of possible sub-area hot spots caused by emissions trading in a pioneering application of a cap-and-trade market approach to reducing aggregate stationary-source volatile organic compound emissions in the Chicago severe ozone non-attainment region. When sub-areas are defined as populated zip codes, 89 out of 95 affected codes ...

Analysis of point source emissions in the Texas-Mexico border region
Pollutant emissions in the Texas-Mexico border were investigated using an emission database that covers 25 Texas counties and the states of Coahuila, Chihuahua, Nuevo Leon and Tamaulipas in Mexico. Major emissions are from energy generation, mainly from two coal-fired facilities in Coahuila, which also generate most of carbon dioxide. Texas exhibits a larger concentration of sources; around ...

How to Choose Harmless Fire Brick
When it comes to selecting fire bricks for your elevated-temperature applications, it's important to prioritise not only their performance but also their impact on health and the environment. Fire bricks, also known as refractory bricks, are designed to withstand extreme heat and provide insulation and structural support in industrial settings. However, some fire bricks contain harmful substances ...

`The Advantages & Drawbacks of the EPA`s Coating & Composites Coordinated Rule Development,` presented at the 2000 SUR
Introduction Under the 1990 Clean Air Act Amendments (CAAA), the U.S. EPA is required to regulate sources of hazardous air pollutants (HAPs). Primarily, HAP emissions are regulated through National Emission Standards for Hazardous Air Pollutants (NESHAPs), which are codified under Title 40 Code of Federal Regulations (CFR)Part63. NESHAPs address HAP emissions from a particular process or ...

The problem (and solution) of vent gases from hydrocarbon and chemical storage tanks
The problem (and solution) of vent gases from hydrocarbon and chemical storage tanks. During chemical products and hydrocarbon bulk liquid storage (the so-called tank breathing), product loading and unloading, transport, cleaning and inerting of tanks, pollutant emissions are emitted into the atmosphere. These emissions are mostly emissions of Volatile Organic Compounds (VOC) and must must be ...

Vehicular Emission Monitoring for Toll Booth Automation - Case Study
To demonstrate the efficiency of automated toll booths, Oizom installed Polludrone and helped Quantela monitor the Air Quality at Shahjahanpur toll booth, Alwar. The pollution levels increase by up to 8 times in congested traffic, which can be avoided by implementing automated toll booths. Polludrone monitored the real-time air quality at the toll booth and studied the increase in vehicular ...
