Introduction Volatile organic compounds (VOCs) are a significant class of air pollutants that have widespread impacts on environmental pollution and human health. These organic chemicals have a high vapor pressure at room temperature, which means they can easily evaporate into the atmosphere. Understanding the sources, effects, and control of VOCs is crucial for managing air…
Introduction to Volatile Organic Compounds (VOCs) in the Atmosphere Volatile Organic Compounds (VOCs) are a significant group of organic chemicals characterized by their high vapor pressure at room temperature, leading to substantial emissions into the atmosphere. These compounds are composed of elements such as carbon, hydrogen, oxygen, and nitrogen, among others. The presence of VOCs…
Microplastics are small plastic particles, typically less than 5 millimeters in diameter. They originate from a variety of plastic materials, which consist of numerous chemical compounds. Here is a list of common polymers and chemical compounds responsible for the formation of microplastics: Polymers Additives and Chemical Compounds These compounds are often released into the environment…
Introduction Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) is a powerful analytical technique used for the detection and quantification of volatile organic compounds (VOCs) in environmental samples. This article will provide an overview of the principles, components, and applications of SIFT-MS in environmental analysis. Principle of SIFT-MS SIFT-MS is based on the principle of ion-molecule…
