New Research Highlights Threat from Pollutants in Rivers Test & Itchen

Pollutants in Test Itchen Rivers

Portsmouth University Research Paper on Polar Organic Contaminants in the Rivers Test and Itchen

This article provides an overview of the research led by Portsmouth University into the level of pollution by polar organic contaminants in the Test & Itchen. The Test and Itchen Association part funded this vital research with a grant of £3450. 

Researchers deployed Chemcatcher passive samplers across these rivers to quantify these contaminants and assess the risks they pose to the aquatic environment. These samples were then analyzed using mass spectrometry techniques and some statistical weighting to give time and spatial trends.    

The study underscores the urgent need for concerted efforts to mitigate the impact of polar organic contaminants on the Rivers Test and Itchen.

What are Polar Organic Contaminants?

Polar organic contaminants are chemicals that have polar molecular structures, meaning they have regions with positive and negative charges. These chemicals are often water-soluble and can easily enter aquatic environments through various pathways, including agricultural runoff, wastewater discharge, and industrial processes. Common examples include pharmaceuticals, personal care products, pesticides, and herbicides. Because of their polarity, these contaminants can persist in water bodies and pose risks to aquatic life, leading to potential ecological and health impacts.
