Air Pollution Part 4 – Reduction Methods
With all said about emissions of pollutants in preceding blogs, it should also be noted that there are multiple methods available and in frequent use to reduce the emissions at their sources, both of gaseous substances and particulates. Addressing Particulates To start with the latter, there are cyclones, electrostatic filters, and fabric filters that can catch the particles before being ...

Air Pollution Part 2 – Sources of Gaseous Substances
Air pollutants are effectively either specific gas-phase molecules or small solid-phase particles suspended in the air. The latter are as a collective referred to as particulates. Let’s take a closer look at the origins of gaseous pollutants. Many anthropogenic activities give rise to gaseous air pollutants, but there are also a few natural sources. Stationary and Mobile Combustion ...

What Is A NOx Scrubber?
“NOx scrubber” refers to an air pollution control device used to reduce or eliminate nitrogen oxide (NOx) emissions from industrial processes, power plants, and other sources. Nitrogen oxides are a class of harmful pollutants that adversely affect human health and the environment. NOx scrubbers are designed to reduce these emissions by employing various chemical and physical ...

Using Gas Sensors to Improve Indoor Air Quality
Introduction Indoor air quality (IAQ) is a critical factor that affects our health and well-being. Poor IAQ can lead to a range of health issues, including respiratory problems, allergies, and even more serious conditions such as asthma and lung cancer. It is therefore essential to monitor and improve IAQ, especially in indoor environments where we spend a significant amount of time, such as ...

Factory Flue Gas Treatment Methods
Flue gas treatment is a process that removes pollutants from exhaust gases produced by industrial processes, power plants, and other sources before they are emitted into the atmosphere. Specific flue gas treatment processes can vary based on the type of contaminants and regulatory requirements. The following is an overview of typical flue gas treatment processes: Flue Gas Collection: The first ...

Flue gas treatment process
Flue gas treatment is a process that aims to reduce the emissions of harmful pollutants from the exhaust gases produced by industrial facilities, power plants, and other combustion processes. The treatment of flue gas is essential to mitigate the environmental and health impacts of air pollution. Various technologies and methods are employed in flue gas treatment, depending on the specific ...

Effect of air pollution on plants and animals
Air pollution, emerging as a formidable adversary to global ecosystems, is primarily born from the unbridled activities of industrialisation, urban sprawl, and transport congestion. Both plants and animals, the core pillars of our ecological fabric, grapple with the multidimensional repercussions of deteriorating air quality. A profound understanding of these ramifications is imperative, ...

Why it is crucial for different levels of government to cooperate when it comes to improving air quality and climate change
Both air pollution and climate change are environmental issues that extend far beyond where pollution sources or contributing factors may originate. Because they cannot be contained in one area, it is essential that different levels of government — national, state, and local — cooperate to improve air quality and mitigate climate change. The work occurring at different levels of ...

Spring is in the Air
The types of air pollution and the levels vary widely between urban and rural environments, between small communities and densely populated cities, and between different regions. However, there are also effects owing to the seasonal variations during the year.The first seasons-related thing happening early spring can very well be short periods of high levels of particulates in the air. This owes ...

Working principle and application of NO2 gas sensor
A nitrogen dioxide gas sensor is an electronic device used to detect the presence of nitrogen dioxide (NO2) gas in the environment. Nitrogen dioxide is a highly toxic gas that can cause a range of health problems when inhaled, including breathing problems, lung damage and even death. NO2 gas sensors are used in a variety of applications, including air quality monitoring, environmental monitoring ...

What are the useful exhaust gas treatment equipment in the factory?
Several types of equipment are used to treat factory exhaust, depending on the specific pollutants that need to be removed. 5 common types of fee processing equipment 1. Wet scrubber: wet scrubber is a type of air pollution control device that uses a liquid (usually water) to remove pollutants from a gas stream. The gas stream is forced through a mist or spray of the liquid, which captures the ...

Measuring Indoor Air Pollution on a Hut Trip with the UPAS v2+
Like many Coloradoans, the team members that make up Access Sensor Technologies’ engineering department love to go on hut trips. A “hut” is a cabin in the Colorado backcountry where the main attractions are skiing and snowboarding. There’s not much that beats panoramic views of snow-capped 14,000-foot mountains, fresh champagne powder, and cooked-from-scratch dinners with ...

Steps toward cleaner air: A closer look at the air quality and climate benefits of renewable energy
TL;DR — Renewable energy is becoming an increasingly inexpensive, popular, and viable energy source. The negative impacts that non-renewable energy sources like fossil fuels have on air quality, climate change, and environmental health have become increasingly clear. By increasingly relying on renewable energy sources like wind and solar power, we can reap a wide variety of benefits ...

Clean air cities: Innovative approaches to improving air quality in urban settings
TL;DR - Air quality tends to be worse in urban areas where pollution sources like power generation, vehicle traffic, and construction contribute to high pollution levels. Particulate matter and nitrogen dioxide are major pollutants of concern when it comes to urban air quality, and both have significant negative health consequences. In order to combat urban air pollution, a variety of innovative ...

Electrochemical NO2 gas sensor in NOx pollution control
Background: Nitrogen dioxide gas concentration can be measured by electrochemical NO2 gas sensor. On the one hand, under certain conditions, nitrogen dioxide can combine with hydrocarbons in the air to form photochemical smog. Damage the air quality of the atmosphere environment, seriously harm people’s health, so that people rely on the air environment is polluted. Sulfur oxides and ...

Air quality, cognition, and mental health: How air pollution impacts the brain
TL;DR - While air pollution’s negative impacts on the lungs and cardiovascular system are well-recognized, poor air quality also has adverse consequences on the brain and affects mental and cognitive health. We examine how air pollution affects us in every stage of life, beginning in utero and continuing until old age - as well as how these cognitive and mental health impacts ...

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 detect the amount of NOX we are ...
