Formaldehyde is widely used in the manufacturing of building materials, cars, plywood, polymers, glues, and adhesives. It is also commonly used in household items as a preservative and disinfectant. Due to high toxicity and suspected carcinogenicity, treated effluent wastewater is routinely tested using EPA 8315 high pressure liquid chromatography (HPLC). Regulatory agencies want to review the free formaldehyde content to ensure the future safety of human and eco life. Please inquire should you or your clients need assistance.
