Air, Odours, Noise

Air pollution is the second environmental concern in Europe after climate change, affecting both health and ecosystems. It is the cause of many diseases and thousands of premature deaths (e.g. respiratory and cardiovascular pathologies, but also cell and tissue damage due to the oxidizing potential of certain particles) and has major impacts on biodiversity (acidification), agricultural yields and buildings. At the same time, indoor air pollution has also become a major public health issue as we spend on average 85% of our time in closed environments where chemical, biological and physical pollutants can develop, whether they are related to building components, furniture and decoration, combustion appliances or simply our lifestyles.

For their part, even if they are not systematically responsible for pathologies, olfactory nuisances must also be treated. In this field marked by a large part of subjectivity, several types of solutions exist, from analysis to treatment and reduction at the source.

Finally, as a growing concern in Europe, noise pollution has proven health impacts. In addition to discomfort or direct effects on hearing, excessive noise can lead to sleep disturbances and have an impact on attitudes and behavior. It can disrupt the endocrine or immune system, or even play an aggravating role for certain pathologies (cardiovascular disorders, depression). In 2016, a survey published by the CNB and Ademe estimated the social cost of noise in France at 57 billion euros.

In the field of air quality, there are three main types of solutions: measuring and monitoring instruments; treatment tools and equipment (filtration, suction, purification, dust removal, ventilation, etc.) and low-impact solutions (materials, engines or heating systems with lower emissions, devices to reduce braking emissions, "soft mobility" solutions, etc.). In France, Inéri...

While a majority of us has become more sensitive to noise after the first period of lockdown, the issue of noise abatement remains at the heart of current events. Taking action to reduce exposure to noise is one of the various measures in the planned PNSE4* (see Focus Area 2: "Reducing environmental exposures affecting our health") in the same way as improving indoor air qualit...

Whether they come from industrial, agricultural (livestock farming) or WWTP facilities or from waste treatment, composting or methanization centers, odors are subject to the Environmental Code (see ICPE) and are sampled and measured to classify them and assess their intensity in order to better remedy them. Various players are specialized in diagnosing and auditing these odor n...
