chlorine is a highly reactive, greenish-yellow gas.

Chlorine monitoring

Elemental chlorine is a highly reactive, greenish-yellow gas. It has a suffocating, irritating, and pungent bleach-like odour that is detectable at low concentrations (above 0.3 – 0.5 ppm). Therefore, continuous or high-level exposure of the Cl2 can quickly deaden a person’s sense of smell, making the odour of Cl2 an unreliable indicator of its presence. …

Methyl mercaptan is a colourless, highly flammable, toxic gas with a distinct, strong unpleasant odour.

Methyl Mercaptan monitoring

Methyl mercaptan (CH3SH), also known as methanethiol, is a colourless, highly flammable, toxic gas with a distinct, strong unpleasant odour. Moreover, microbial degradation of organic matter releases methyl mercaptan. As a result, prolonged exposure to CH3SH can quickly deaden a person’s sense of smell, making the odour of methyl mercaptan an unreliable indicator of its …

Methane is a colourless, odourless, tasteless, non-toxic gas with the chemical composition of one carbon and four hydrogen atoms.

CH4 monitoring

Methane has a direct influence on climate change as well as an indirect effect on human health, plant yield, and productivity due to its role as an important precursor to ground-level ozone formation. Therefore, CH4 monitoring is an efficient way to detect the buildup of CH4 levels and take necessary actions. This article covers information …

VOCs are a group of compounds containing carbon that have a high vapor pressure i.e. easily convert into vapor or gases and have low water solubility.

TVOC monitoring

Total Volatile Organic Compounds (TVOC) are a group of compounds containing carbon that have a high vapor pressure present in the air. There are abundant VOC emitted from everyday activities among which some are colourless and some odourless and some are toxic. Therefore, TVOC monitoring is an efficient way to detect exposure to toxic VOCs. …

H2S is colorless, flammable, poisonous, and corrosive gas with one sulfur atom bonded to two hydrogen atoms.

H2S monitoring

H2S is formed whenever elemental sulfur or sulfur-containing compounds come into contact with organic materials at high temperatures. Continuous or high-level exposure to the H2S can quickly deaden a person’s sense of smell, making the odour of H2S an unreliable indicator of its presence. Hence, other means such as hydrogen sulfide monitoring is a viable …

Ammonia is a colorless gas at room temperature with a very pungent smell consisting of one nitrogen atom bonded to three hydrogen atoms.

NH3 monitoring

Ammonia is a colorless, toxic, irritating gas with a pungent odor that is as a result released from decaying organic matter, including plants, animals,  animal wastes, and fertilizer use. As a result, prolonged exposure of the NH3 can quickly deaden a person’s sense of smell, making the odor of NH3 an unreliable indicator of its presence. …

Ozone is a highly reactive gas with three oxygen atoms.

Ozone monitoring

Ground-level ozone is harmful to human health and the environment, especially on sunny days when its concentration can reach high levels. Also, it is a precursor of photochemical smog, which has its fatal effects. Real-time O3 monitoring helps in calculating the air quality index to deliver health advisories as well as formulating an action plan …

SO2 is a dense, colorless, toxic, non-flammable, reactive gas composed of one sulfur atom bonded to two oxygen atoms.

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, …

NOx is a collective term used to refer to the nitrogen oxides that are most relevant for air pollution i.e. NO and NO2.

NOx monitoring

NOx, apart from affecting human health and the environment itself, has the potential to produce “secondary pollutants” such as ozone, smog, nitric acid, and particulate matter. Also, these pollutants have negative effects on health and the environment. NOx monitoring is an efficient way to prevent the accumulation of high levels of NOx as it helps …

Carbon monoxide is a colorless, odorless, non-irritating, tasteless, poisonous gas found in the atmosphere.

Carbon Monoxide Monitoring

Carbon monoxide, one of the most abundant pollutant gases. The gas is indetectable to humans as one can not see, smell, or taste. However, exposure to high levels of CO can cause CO poisoning leading to serious health issues, giving it the name “The Silent Killer.” CO monitoring is the most effective way to know …
