Air Toxicity TestingAir toxicity testing is the comprehensive assessment of harmful substances to identify potential health hazards and develop targeted mitigation strategies. By combining cutting-edge analytical techniques with innovative biological assessment methods, we can provide our clients with a comprehensive understanding of their air quality challenges and develop tailored solutions to protect human health and the environment.
Indoor and outdoor air quality is a crucial factor in maintaining human health and environmental sustainability. However, the complex mixture of chemical pollutants, particulates, and biological contaminants present in air can pose significant risks to our well-being.
Traditionally, air quality evaluations have relied on the measurement of individual chemical concentrations, such as volatile organic compounds (VOCs), formaldehyde, and carbon dioxide. While these targeted approaches provide some insight, they fail to capture the true nature of air pollution, which often arises from the synergistic effects of multiple compounds present at low levels. Modern air toxicity testing employs a more holistic, mixture-based approach to better understand the combined impact of these contaminants on human health and the environment.

Comprehensive air toxicity testing begins with the identification and quantification of a wide range of chemical compounds, including VOCs, semi-volatile organic compounds (SVOCs), combustion byproducts, and emerging contaminants. Techniques such as parts-per-billion photo-ionizing detectors and EPA TO-15 mass spectrometry analysis provide a detailed chemical profile of the air samples.
Traditional risk assessment approaches that focus on individual chemical concentrations often fail to capture the true complexity of air pollution. Air toxicity testing addresses this gap by investigating the synergistic and antagonistic effects of chemical mixtures. This mixture toxicity evaluation helps to identify potential health risks that may be overlooked when only considering the toxicity of individual compounds.
To assess the potential health impacts of air pollutant mixtures, air toxicity testing employs a battery of in vitro bioassays. These cell-based methods evaluate various toxicological endpoints, including cytotoxicity, immunotoxicity, skin sensitization, and endocrine disruption.
In addition to targeted chemical analysis, air toxicity testing also incorporates non-targeted "total chemical scans" to identify the presence of unknown or unexpected compounds in air samples. This approach can reveal the presence of emerging contaminants or unregulated substances that may contribute to the overall toxicity of the air.
