When discussing air testing, the first question many people have is “how are samples collected?” While many people picture collecting a sample of air in a jar or some other simple container, the actual process is much more efficient than that. All in all, air samples typically require a filtration process in which the air is pushed through a filter or slide and the contents of the filter/slide are then analyzed for particulate matter and contaminants. That’s exactly why we use Air-O-Cell® Cassettes.

Air-O-Cell® Cassettes are manufactured by Zefon International and are basically miniature air filtration chambers that catch air contaminants on a small slide for microscopic analysis. Contaminant-laden air is pushed through an inlet slit using an air pump and directed toward the slide. The air passes through the chamber, leaving particles behind on the slide and passing out of the other side of the chamber. This slide can then be extracted from the cassette and analyzed directly underneath a microscope for particles and contaminants.

Quality drinking water is essential for our health and well-being. Testing water quality is important for municipalities, businesses, and homeowners. Whether water is used for drinking or irrigation, it’s vital that water quality is monitored regularly so that any problems can be addressed in a timely manner.
In this article, you will learn about common water contaminants and why it’s important to contact commercial laboratories for regular testing of water quality.

What are the most common contaminants in the United States?

According to the Centers for Disease Control and Prevention (CDC), common contaminants can be biological, pathogenic, chemical and mineral. Below, we will discuss some of the most common contaminants and the impact they have on individuals who ingest them.

If you live in an older home and/or you’re planning renovations, it is wise to consider the potential for asbestos exposure in your home. Removing asbestos from the home can be an arduous process.

The first step to removing this potentially dangerous material from your home is to properly identify it. Asbestos can persist in a variety of areas within your home including acoustic ceiling spray, floor tiles, linoleums, insulations, drywall/joint compounds, exterior stuccos, roofing, etc. Thus, it is very important to have testing performed prior to initiating the demolition or renovation process in your home. By contacting professionals, you can ensure that your home and your family is safe from asbestos exposure before, during, and after your renovation.

Long-term exposure to lead can be fatal. Lead can affect almost all organs of the body. Both children and adults can experience negative effects from lead poisoning.  Even low amounts of lead exposure can result in severe health consequences.

Here are five household items that can be warning signs that you may have lead inside the house. You should contact a professional lead testing company if you suspect the presence of lead. This is important to avoid exposure to lead and to ensure the safety of your household members.

1. Piping and Paint in Old Homes

One of the most common sources of lead poisoning at home is piping and paint containing lead. Your house may have lead piping and paints if it was built prior to 1978. The federal government banned lead in consumer use paints that year. In general lead pipes were not used after the 1920s, but it was still allowed for solder in drinking water systems until 1986.
