Sand, an increasingly scarce resource that needs to be replaced

sable, sand

Humans are big consumers of sand, to the extent that this now valuable resource is becoming increasingly scarce. Being in such high demand, it is extracted in conditions that aren’t always respectful of the environment. With the increasing scarcity of sand and the sometimes devastating consequences of mining at beaches, …

How can AI help better forecast high and low water levels?

flood water level

Predicting the level of water in rivers or streams can prove to be invaluable in areas with a high risk of flooding or droughts. While traditional models are based primarily on hypotheses about processes, another approach is emerging: artificial neural networks. Anne Johannet, an environmental engineering researcher at IMT Mines …

Indoor Air: under-estimated pollutants

Indoor air

While some sources of indoor air pollution are well known, there are others that researchers do not yet fully understand. This is the case for cleaning products and essential oils. The volatile organic compounds (VOCs) they become and their dynamics within buildings are being studied by chemists at IMT Lille …

The many layers of our environmental impact

The water footprint of a product has long been difficult to evaluate. Where does the water come from? What technology is used to process and transport it? These are among the questions researchers have to answer in better measuring environmental impact.

An activity can have many consequences for the environment, from its carbon footprint, water consumption, pollution, changes to biodiversity, etc. Our impacts are so complex that an entire field of research has been developed to evaluate and compare them. At IMT Mines Alès, a team of researchers is working on …

CUBAIR: a prototype for purifying indoor air

CUBAIR : un prototype pour purifier l’air intérieur

Improving indoor air quality? That’s what the CUBAIR project aims to do. By developing a new treatment system, researchers have managed to significantly reduce fine particle concentration and nitrogen oxides.   An important reminder: indoor air is often more polluted than outdoor air. In addition to the automobile exhaust and …

Fine particles: how can their impact on health be better assessed?

fine particles

In order to assess the danger posed by fine particles in ambient air, it is crucial to do more than simply take regulatory measurements of their mass in the air. The diversity of their chemical composition means that different toxicological impacts are possible for an equal mass. Chemists at IMT …

What’s new in the atmosphere?

atmosphere

In conjunction with the 4th National Conference on Air Quality held in Montrouge on 9 and 10 October 2018, I’MTech sat down with François Mathé, a researcher in atmospheric sciences at IMT Lille Douai to ask him five questions. He gave us a glimpse of the major changes ahead in …

The contest for the worst air pollutant

Laurent Alleman, IMT Lille Douai – Institut Mines-Telecom In its report published on June 28, 2018, the French Agency for Health Safety (ANSES) presented a list of 13 new priority air pollutants to monitor. Several air pollutants that are harmful to human health are already regulated and closely monitored at …

Will the earth stop rotating after August 1st?

Earth

By Natacha Gondran, researcher at Mines Saint-Étienne, and Aurélien Boutaud. The original version of this article (in French) was published in The Conversation. It has become an annual summer tradition, much like France’s Music Festival or the Tour de France. Every August, right when French people are focused on enjoying …

Atmospheric reactive trace gases: low concentrations, major consequences

Despite only being present in very small quantities, trace gases leave their mark on the atmospheric composition. Since they are reactive, they may lead to the formation of secondary compounds such as ozone or aerosols that have a significant impact on health and the climate. IMT Lille Douai is a …
