Dioxin and Furans Testing Services

In the realm of environmental contaminants, dioxins, and furans are two highly regulated groups that pose significant risks to human health and the environment. CD BioSciences is a renowned company dedicated to soil testing services, we are well-versed in the intricacies of dioxin and furans testing.

Introduction to Dioxin and Furans

Dioxins and furans encompass a cluster of exceptionally hazardous and enduring organic pollutants, categorized as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Originating as byproducts from diverse industrial operations that utilize chlorine, these compounds emerge during activities such as waste incineration, chemical production, and the manufacturing of specific herbicides and pesticides.

Dioxins and furans possess a distinctive chemical structure, comprising two interconnected aromatic rings bonded by oxygen atoms. The degree of toxicity exhibited by these compounds varies based on the number and arrangement of chlorine atoms attached to the aromatic rings. Among them, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), commonly known as "dioxin," stands out as the most potent congener. These compounds have been linked to detrimental effects on human health, including their potential to act as carcinogens, teratogens, and immunotoxins. It is important to acknowledge the adverse properties of dioxins and furans and their significant impact on human well-being.

Method of Dioxin and Furans Testing

• Sample Preparation
  Before analysis, proper sample preparation is essential to ensure accurate and representative results. Our company follows rigorous protocols for sample collection, preservation, and extraction. The choice of extraction method depends on the sample matrix and the target analytes. Commonly used extraction techniques include Soxhlet extraction, accelerated solvent extraction (ASE), and solid-phase microextraction (SPME). These methods aim to efficiently extract dioxins and furans from the sample, ensuring maximum recovery and minimal interference.
• Analytical Techniques
  Using advanced analysis techniques can be quantitative dioxin and furan in environmental samples. The most commonly employed method is Gas Chromatography-Mass Spectrometry (GC-MS). This technique combines the separation power of gas chromatography with the sensitive detection capabilities of mass spectrometry.
  GC-MS analysis involves the separation of dioxins and furans on a capillary column based on their boiling points and polarity. The separated compounds are then ionized and detected by mass spectrometry, allowing for precise identification and quantification. Isotope dilution techniques are often employed to enhance accuracy and reliability.
