Acrylamide testing in waste water
Introduction
As our society continues to advance, so does the need for responsible industrial practices and environmental protection. Among the various concerns facing our ecosystems, the presence of acrylamide in wastewater has emerged as a pressing issue. Acrylamide is a synthetic organic compound widely used in industrial processes, making its way into wastewater and posing potential risks to both human health and the environment. In this blog, we'll take an in-depth look at the importance of acrylamide testing in wastewater, exploring its significance in safeguarding our water resources and ensuring a cleaner, safer future for all.
What is Acrylamide, and how does it end up in wastewater?
Acrylamide (C3H5NO) is a colorless, odorless, and water-soluble chemical compound with various industrial applications. It is primarily used in the production of polyacrylamide, a polymer used in wastewater treatment processes to aid in solid-liquid separation. Additionally, acrylamide finds use in various industries, including the petroleum, paper, and mining sectors, as well as in the production of certain cosmetics and adhesives.
Unfortunately, due to its extensive use, acrylamide can enter wastewater through multiple pathways:
Industrial Discharges: Industries that utilize acrylamide or produce it as a byproduct can release the compound into wastewater during their manufacturing processes. These effluents may contain high concentrations of acrylamide, posing significant risks to the environment if not properly treated.
Runoff and Leaching: Acrylamide-containing chemicals used in agricultural practices or urban settings can be washed into wastewater systems through runoff and leaching. This is particularly concerning, as it may lead to widespread contamination of water bodies.
Domestic Sources: While the primary source of acrylamide in wastewater is industrial, certain consumer products like certain cosmetics and adhesives may contribute to its presence if not disposed of correctly.

Market overview
In 2022, the global environmental testing market was valued at approximately USD 11.07 billion. Experts predict that this market will experience substantial growth with a compound annual growth rate (CAGR) of 7.8% from 2023 to 2030
Regulations and standards
The CPCB's regulations for acrylonitrile and acrylamide monomer are as follows:
- The maximum permissible limit (MPL) for acrylonitrile in wastewater is 0.1 milligrams per litre (mg/L).
- The MPL for acrylamide monomer in wastewater is 0.2 milligrams per litre (mg/L).
These regulations are based on the recommendations of the World Health Organization (WHO). The WHO recommends that the concentration of acrylamide in drinking water should not exceed 0.1 µg/L. In the United States, the Environmental Protection Agency (EPA) has set a maximum contaminant level (MCL) for acrylamide in drinking water of 0.0002 milligrams per litre (mg/L). This means that the EPA does not want the average person to drink more than 0.0002 mg of acrylamide per litre of water over a lifetime.
Testing methods
Various methods are used to detect and quantify acrylamide in wastewater samples:
Chromatography Techniques: High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC) are widely employed for their sensitivity and accuracy in identifying trace amounts of acrylamide. These methods can separate and quantify the compound, ensuring precise measurements.
Immunoassays: Enzyme-linked immunosorbent assays (ELISA) offer a cost-effective and rapid screening method for acrylamide detection in wastewater samples. ELISA kits are designed to detect specific molecules, including acrylamide, by utilizing antibodies and colorimetric reactions.
Spectroscopy: Infrared (IR) spectroscopy and Mass Spectrometry (MS) can be used to analyze wastewater samples for acrylamide content. IR spectroscopy identifies compounds based on their unique molecular vibrations, while MS provides highly sensitive and specific measurements of molecular masses.
