Persistent Organic Pollutants

ACS provides a full and thorough service for the analysis of Persistent Organic Pollutants (POPs) in almost any sample matrix from our UKAS accredited laboratory.

Using state-of-the-art GCMS QQQ and LCMS QQQ, we offer high-quality mass spectrometry analysis for the full range of pollutants as per the Stockholm Convention.

We can analyse a variety of sample types, including:

Waters
Soils
Aggregates
Ash
Air Pollution Control residues (APCr)

Industrial liquids
Powders
Films
E-Waste
Resins and Plastics

Depending on the sample matrix, we can achieve very low levels of detection with very small amounts of sample.

What are Persistent Organic Pollutants?

Persistent Organic Pollutants are toxic compounds that typically originate from industrial sources. They can remain in the environment for long periods and can be spread by air and water currents to impact the wider environment. The effects of POPs on people and wildlife range from cancer and reproductive problems to the disruption of normal development processes.

If not handled responsibly, these pollutants can enter the food chain, leading to significant health risks for anyone consuming POPs-contaminated food or water.

To avoid this, a proactive approach must be taken to reduce pollution levels through responsible waste management practices, including the proper disposal of hazardous materials and strict enforcement of environmental laws.

The 12 Initial POPs under the Stockholm Convention

Initially, there were twelve POPs recognised as causing adverse effects on humans and the ecosystem, which are placed into three categories:

Pesticides
Industrial Chemicals

By-Products

Since June 2017, an additional sixteen POPs were added to the Stockholm Convention. You can view the complete list with a detailed risk profile on the Stockholm Convention New POPs page.

Analysis of Pesticide Residues

Analysis of pesticide residues is undertaken using a variety of complex methods designed to detect Persistent Organic Pollutants in the food or water supply. These tests can detect whether pesticide residues have been transferred from plants or animals, and if so, at what concentration levels. They also help identify long-term environmental effects caused by these chemicals.

Our experienced team conducts the tests using sophisticated equipment like high-resolution chromatography and mass spectrometry, which measure very small concentrations of toxic chemicals that may be present in samples.

By identifying potential sources of contamination, this testing allows for an accurate assessment of risks associated with exposure to these chemicals so that appropriate measures can be taken to reduce any potential adverse effects.

Test results from the analysis of pesticide residues can also be used to improve the production and management of pesticide usage and inform policies designed to protect human health and the environment.

Persistent Organic Pollutants Regulations

The UK’s Persistent Organic Pollutants Regulations 2007 aims to protect people and the environment from the damaging impacts of POPs. By complying with these regulations, businesses can reduce the risk associated with using and disposing of POP-contaminated chemicals.

The regulations set out specific requirements for the handling, storing, and transporting of products and substances containing Persistent Organic Pollutants, as well as identifying their hazardous properties. To ensure compliance, it is essential that businesses are aware of their obligations under the law when dealing with these types of substances and products.

Persistent Organic Pollutants regulations in the UK aim to:

Protect people and the environment from the damaging impacts of POPs
Set out specific requirements for handling, storing and transporting POPs-containing substances and products

Monitor regularly for any possible risks or spillages
Reduce costs associated with clean-up operations

By adhering to these regulations, your business will remain compliant, help preserve the environment, and protect public health.

See the Government guidance on POPs for more information.

Frequently Asked Questions

What is the Stockholm Convention?

The Stockholm Convention on Persistent Organic Pollutants is a global treaty set out to protect human health and the environment from the use or disposal of certain toxic chemicals. The convention requires that participating countries adopt and introduce specific standards to reduce releases of POPs into the environment and minimise human and wildlife exposure.

How many POPs are listed in the Stockholm Convention?

There are currently 28 POPs listed in the Stockholm Convention on Persistent Organic Pollutants. They fall into 3 overarching categories: Industrial chemicals, pesticides, and certain homologue groups of poly-brominated diphenyl ethers (PBDEs) and unintentional by-products of combustion, industrial processes, and non-industrial processes.

What effects do POPs have on humans?

Evidence shows that long-term exposure to POPs can lead to reproductive disorders, increased cancer risk, changes to the immune system, disruption of normal development processes, and more. Anyone who consumes POPs-contaminated food or water is at significant risk of harm, making POPs testing vital to the well-being of people and wildlife.

How do you test for POPs?

There are several methods for POPs testing, and popular procedures include GC-MS, LC-MS, and ELISA. The choice of method will depend on the substance being tested for, the sample conditions, and the required level of sensitivity and specificity.
