Examples of particulates include dust, smoke, soot, and pollen. Particulates are small solid particles or liquid droplets suspended in the air. They can come from a variety of sources such as vehicle emissions, industrial processes, and natural events like forest fires.
Particulates in the air can originate from various sources, including natural and anthropogenic activities. Natural sources include dust from deserts, wildfires, and volcanic eruptions, while human-made sources involve emissions from vehicles, industrial processes, construction activities, and burning fossil fuels. Additionally, household activities, such as cooking and heating, can contribute to indoor particulate pollution. The composition and concentration of particulates can vary significantly based on location and time.
Particulates, also known as particulate matter (PM), can be found in the air we breathe, originating from various sources including vehicle emissions, industrial processes, construction activities, and natural events like wildfires and volcanic eruptions. They can also be present indoors, coming from sources like tobacco smoke, cooking, and dust. Particulates vary in size, composition, and origin, and can have significant health and environmental impacts.
The four most common non-renewable resources are gas, oil, coal and copper.
The two most common sources of home fires are small heaters and fires that start in the kitchen during cooking. Another common cause is faulty electrical wiring. The fires that cause the most deaths start from carlessness with cigarettes.

Particulates are tiny subdivisions of solid matter suspended in a gas or liquid. Sources of particulate matter can be man made or natural like Air pollution and water pollution can take the form of solid particulate matter. Particulates is a complex mixture of extremely small particles and liquid droplets.
We use DC voltages in an electrostatic precipitator (ESP) because it is necessary to induce a charge on the particulates, and then attract them to a plate by the use of an opposite charge. An AC source would be changing constantly. That would leave our particulates picking up "different charges" at different times as they pass the plates. Further, these particulates wouldn't be attracted to the plates because the plates would be changing polarity as well. ESP's use a DC source to apply a charge of a given polarity to the particulates in the air stream, and use a plate of the opposite charge to attract and "hold" the particulates. AC sources can't do that.
