Contaminants of emerging concern

Mass spectrometry is a good tool to have in your toolbox as you examine the sources and potential effects of contaminants of emerging concern (CECs) on the environment.

Contaminants of emerging concern (CECs) is a general term that covers a broad class of different types of chemical compounds, including medicines, personal care or household cleaning products, flame retardants, lawn care and agricultural products. These diverse compounds are classified as “emerging” because they are often newly identified manufactured or naturally occurring chemicals that are detected in various matrices at insignificant levels. This is why, in most cases, CECs do not have applicable regulatory health standards.

While not commonly monitored, these chemicals can enter the environment and trigger known or suspected ecological effects that can affect human health. CECs are consistently found in groundwater, surface water, municipal wastewater, drinking water, soil and food sources. The persistence of these chemicals is a threat as they can potentially bioaccumulate in crops, in the environment and in our bodies. As such, environmental researchers need a way to study the fate, bioavailability, adverse outcome pathways and environmental impact of CECs.

Because CECs are broadly defined as any chemical or microorganism that is not currently routinely monitored, in many cases, these compounds are orders of magnitude below known acute toxicity levels and require detection at very low levels.

This is where liquid chromatography-tandem mass spectrometry (LC-MS/MS) can come into play.
