Determination of a pollutant in a sample

The determination of a pollutant in a sample consists of identifying and quantifying the presence of organic or inorganic contaminants in different environments (soil, air, water, materials, food). This analysis makes it possible to characterize the nature, concentration and distribution of pollutants, in order to assess their impact on the environment, human health or the regulatory compliance of industrial products.
This type of analysis is essential for:

• Demonstrate the environmental compliance of a material or product.
• Identify a source of contamination in a manufacturing process.
• Meet regulatory requirements (REACH, RoHS, CLP, etc.).
• Monitor the quality of packaging, polymers and materials in contact with food or cosmetic products.

Analytical methods used

The techniques used to measure a pollutant depend on the chemical nature of the contaminant being tested. YesWeLab's partner laboratories use highly sensitive and selective methods:

• GC-MS (Gas Chromatography-Mass Spectrometry) : suitable for the detection of volatile and semi-volatile organic pollutants such as polycyclic aromatic hydrocarbons (PAHs) , pesticides , phthalates or solvent residues .
• LC-MS/MS (Liquid Chromatography coupled with Tandem Mass Spectrometry) : used for the analysis of non-volatile organic pollutants such as drugs , endocrine disruptors , PFAS or polymeric additives .
• ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and ICP-OES/ICP-AES (Atomic Emission Spectrometry) : reference techniques for the detection of heavy metals (lead, cadmium, mercury, arsenic) and trace elements .

These methods guarantee precise quantification , a very low detection limit and complete traceability of results .

Affected matrices

Pollutant determination can be applied to a wide variety of matrices depending on the field of study:

• Water (drinking, wastewater, industrial, groundwater).
• Soils and sediments for environmental pollution assessment.
• Materials and polymers : verification of the conformity of packaging, plastics or composites.
• Food, plant extracts and finished products : control of chemical or metallic contamination.
• Industrial air and dust : monitoring of exposure to volatile organic compounds or metals.

These analyses help guarantee product safety, prevent health risks and ensure compliance with environmental quality standards.

Industrial and regulatory applications

Pollutant dosing plays a key role in several industrial contexts:

• Quality control of materials and packaging : detection of contaminants from manufacturing processes or chemical migration.
• Environmental studies : monitoring soil, water or air pollution as part of site diagnostics.
• Regulatory compliance : compliance with European and international requirements (REACH, RoHS, CLP, POPs, ISO 17025).
• Product safety : prevention of risks linked to the presence of dangerous substances in formulations or packaging.

For polymers and packaging materials , this type of analysis can be supplemented by:

• The dosage of phthalates , often used as plasticizers.
• The determination of bisphenol A (BPA) and its analogues (BPS, BPF, BADGE, BFDGE) for food and regulatory compliance.
• Global and specific migration analysis to assess the safety of materials in contact with food.

Challenges and benefits for manufacturers

The detection and quantification of pollutants makes it possible to:

• Anticipate regulatory non-compliances and avoid product recalls.
• Ensure environmental traceability of production processes.
• Optimize formulations to reduce the presence of unwanted contaminants.
• Strengthen transparency and trust with customers and partners.

The results of the analyses provide essential data for chemical risk management , REACH compliance and certification of eco-designed products .
