The screening of AOX sum parameter is of paramount importance in environmental analysis, particularly when assessing the quality of water, sludge, or soil for contamination by organic halides such as chlorine, bromine, and iodine. These organic halides have the propensity to be adsorbed to activated carbon, potentially leading to adverse effects on the environment and living organisms. The AOX sum parameter refers to the measurement of all organic halogens present in a sample, and it serves as a critical indicator of the overall halogenated organic compounds’ concentration.

Preventing Toxic Effects on Humans, Animals, Plants, and Microorganisms

Uncontrolled presence of AOX in water, sludge, or soil can pose significant risks to human health, aquatic life, plant growth, and microbial ecosystems. These toxic effects can range from mild irritations to severe health issues and ecological disturbances. By diligently monitoring AOX levels with the AOX-400 from Nittoseiko Analytech, potential toxic effects can be promptly identified and mitigated.
