New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects

Envirotec Magazine

The source of pollutants in rivers and freshwater lakes can now be identified using a comprehensive new water quality analysis, according to scientists at the University of Cambridge and Trent University, Canada. Water quality is strongly determined by the diversity of organic matter dissolved in it – termed ‘chemodiversity.’

Porous crystals made from plant extracts purify water from pharmaceutical pollutants

Envirotec Magazine

Hence wastewater treatment plants are facing the challenge of removing emerging organic contaminants (EOCs) such as active pharmaceutical ingredients, and therefore new materials and technologies are required. One strategy for removing pollutants from water is by using porous materials that behave like sponges.

Study flags night-time air pollution in China as potential health threat

Envirotec Magazine

Experts believe that this increase will have significant air pollution implications for China and other developing countries such as India. The study seems to show that, if recent increasing ozone pollution trends continue, nighttime oxidation in China will increase further even if NOx emissions are reduced. Increased O3 and PM2.5

Brazilian group presents novel method of analyzing microplastic pollution

Envirotec Magazine

The last decade has seen some progress with studying plastic pollution, but there are still significant challenges, such as a lack of comparability of reported results, especially when it comes to microplastic particles. Few studies of pollution by MPs have been published in Brazil, especially regarding inland aquatic areas.
