Roadside pollution concentrations can...

Aerosol Research

The Earth is warmed principally by the sun’s radiation which enters the atmosphere. However, not all the radiation penetrates the atmosphere as some is scattered back into space. The amount of back-scattering into space alters the amount of energy that is absorbed into the atmosphere. backscattering of this energy provides valuable information on the change of the earth’s radiation balance and how different activities (artificial and anthropogenic) can affect this delicately balanced...

Haze Monitoring

The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.

Roadside monitoring

Traffic, especially in urban locations, is one of the greatest contributors to air pollution. Traffic produces a variety of different pollutants that include particulates, NO2, NO, CO, hydrocarbons and in some cases SO2. The monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems and many sites that are available can be too far away to be representative of roadside air pollution.

Ozone monitoring

Ozone found in ambient air can have a direct affect on human health and also has the potential to create photochemical smog. It is for this reason that the U.S. EPA has set a one hour limit of 120 ppb and an 8 hour limit of 80 ppb. Ozone has been found to affect human health by harming the respiratory and immune system. People with pre-existing respiratory damage or diseases are more likely to suffer from the affects of ozone.

Carbon Monoxide (CO) monitoring

Carbon monoxide poisoning is the most common type of fatal poisoning in many industrialized countries. Carbon monoxide is a colourless, odorless and tasteless gas caused by the incomplete combustion of hydrocarbon fuels. Carbon monoxide is a toxic gas to the human body, when inhaled it binds to hemoglobin, myoglobin, and mitochondrial cytochrome oxidase reducing oxygen storage, transport and respiration in these organelles.

Nitrogen Oxides (NOx) monitoring

Oxides of Nitrogen (NO/NO2/NOX) is the product of endothermic reactions within combustion engines and causes significant environmental pollution. The main source of NOX is from the engine of automobiles and these pollutants are harmful to humans in their respective forms or in the creation of ozone (O3) or acid rain. NOX is most prevalent in our societies as a contributor to asthmatic conditions as well as the photochemical smog found throughout many industrialized cities.

Sulfur Dioxide (SO2) monitoring

Sulfur Dioxide (SO2) is the product of the combustion of sulfur compounds and causes significant environmental pollution. The main source of sulfur dioxide SO2 in the environment are from various industrial processes such as the burning of coal in power stations, the extraction of metals from ore and combustion of fuel within automobiles.

Carbon Dioxide (CO2) monitoring

Carbon dioxide (CO2) is emitted in a number of ways. It is emitted naturally and through human activities like the burning of fossil fuels. Carbon dioxide (CO2) is generated as a by-product of the combustion of fossil fuels or the burning of vegetable matter, among other chemical processes. Small amounts of carbon dioxide are emitted from volcanoes and other geothermal processes.

Hydrogen Sulfide (H2S) monitoring

Hydrogen sulfide is the chemical compound with the formula H2S. H2S is colorless, toxic and flammable and is responsible for the foul odour of rotten eggs and flatulence. Hydrogen sulfide often results from sulfur reducing bacteria in nonorganic matter (in the absence of oxygen), such as in swamps and sewers (anaerobic digestion). H2S also occurs in volcanic gases, natural gas and some well waters.

Ammonia (NH3) monitoring in Agriculture

Ammonia is a compound featuring a nitrogen molecule attached to three hydrogen molecules (NH3). It is a colorless gas with a characteristic pungent smell similar to human urine, as urine contains a large amount of ammonia in it.

Total Reactive Nitrogen (NOy) monitoring

NOy (total reactive nitrogen) is defined as the sum of NOX plus the compounds produced from the oxidation of NOx which include nitric acid. NOy component species include NO, NO2, NO3, HNO3, N2O5, CH3COO2NO2(PAN), and particulate nitrate.

Total Sulfur monitoring

Total Sulfur includes all the gases described within total reduced sulfur, as well as sulfur dioxide as these compounds are oxidised forms of sulfur. Exposure to sulfur dioxides, and other reduced sulfur based compounds can cause many harmful effects in humans including headaches, general discomfort up to death in large doses. Those with impaired heart or lung function and asthmatics are at increased risk. Sulfur dioxide, one of the major pollutants, is absorbed by soils and plants and captured within and below...

Total Reduced Sulfur (S) monitoring

Total reduced sulfur(s), which include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3), and dimethyl disulfide (CH3S2CH3), occur naturally in the environment and can also be present in numerous industrial gaseous streams – petroleum refining, natural gas extraction, and chemical operations like the pulp/paper industry. Hydrogen sulfide is the most prevalent of the total reduced sulfurs, and is commonly found in volcanic gases, marshes and swamps, wetlands and mud flats,...

Hydrocarbons monitoring

Hydrocarbons are a family of organic chemicals consisting of carbon and hydrogen atoms arranged in a variety of ways. Hydrocarbons are found naturally in crude oil and are released into the environment with its combustion (power plants, home heaters etc).

Particulates PM10 PM2.5 TSP monitoring

Sampling dust and particulate matter is important as dust and particulate matter can affect the health of human populations, as well as the natural environment. Dust and particulate matter can cause respiratory problems when breathed in by humans. Dust and particulates above 10 micrometer (PM10) are filtered and generally do not enter the lungs.
