  • Is the solution to pollution dilution?

    Controls and monitors are part of environments where cleaning and purifying air moves beyond the usual HVAC filters and ventilation air. We can now utilize sensors and real time monitors that identify, track, and assure safe destruction of: mold, odors, allergens, bacteria, viruses, corrosion, chemical gases, and VOCs. Powerful proprietary filter media, adapted to each environment’s unique ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Polluted sites: Groundwater decontamination requires robust level sensors

    Whether it be old landfills, coal tips, former military sites or refineries, what remains behind is contaminated ground, which is a danger to both humans and the environment. In the rehabilitation of these sites, level sensors are required which are resistant to the often aggressive hazardous substances encountered.  Contaminated sites are not only characterized by adverse health or ...

  • AQMesh: a new option for flexible air quality monitoring

    AQMesh has an impressive collection of global users and performance results measuring ambient air quality in applications ranging from traffic planning and urban hotspots to industrial fence line monitoring, building ventilation management, or environmental lobbying. This pole-mounted unit comes with an independent power supply and communications, so offering the possibility of measuring air ...

  • Tracking pollution at a personal level

    Two big stories from 2014 were the amount of air pollution in cities, especially in China, and the rise of “wearables” and other personal technologies people use to track things about themselves, often having to do with health and fitness measurements, such as steps taken, hours slept, heart rate and more. Now, the ...

  • Wireless monitoring for a safe indoor environment

    This article discusses the benefits of wireless technology for continously monitoring the indoor environment. In striving for the construction of energy efficient and cost-effective buildings, the imperative issue of the buildings Indoor Air Quality (IAQ) is often overlooked. This can often lead to a unhealthy indoor environment and even to conditions such as Sick Building Syndrome (SBS) or other ...

  • Observational needs for four-dimensional air quality characterization

    Surface-based monitoring programs provide the foundation for associating air pollution and causal effects in human health studies, and they support the development of air quality standards and the preparation of emission reduction strategies. While surface-oriented networks remain a key tool for addressing traditional single pollutant human exposure challenges, these networks in isolation are not ...

  • Cities in France become smarter thanks to Lufft Sensors

    CITYRAMA Smart Data for Smart Cities, is a French company and a subsidiary of Mobile Tech People (DPW), is an IoT (Internet of Things) platform for intelligent city management.

  • MONITORING & ALERT NETWORK in response to the health problems of Sargasso algae

    Martinique has been facing a major health problem in recent years. Indeed, since 2011, the unprecedented phenomenon of massive stranding of Sargasso algae has affected the Atlantic and southern coasts of Martinique. This phenomenon is the origin of a smelling gas emanating from the putrefaction of algae, among these gases hydrogen sulfide (H2S) and ammonia (NH3). Beyond the olfactory discomfort, ...

  • Sahara Dust pollutes Southern Greece – this is how Lufft Ceilometers can help

    Information related to the range resolved aerosol-cloud physical properties appears to be mandatory for our better understanding of the atmospheric dynamics, air quality and climate change. Recently, the Southern part of Greece  suffered from a severe Saharan Dust outbreak. The dust had been driven across the Mediterranean due to strong south winds. The island of Crete was mostly affected by ...

  • Tracking Air Pollution with Mini Micro Pulse LiDAR - Case Study

    Portable Monitoring Solution Offers Valuable Insight Into Haze Problem Poor air quality in large urban population centers has a negative impact on health and quality of life. To address these issues, the Institute of Urban Meteorology (IUM) in Beijing, China, is conducting fundamental research to better understand, forecast and mitigate atmospheric haze, i.e., air pollution. Over the past ...

  • Compressed breathing air safety - how important is it?

    At first glance the physiological demands of the firefighter, the scuba diver and the hospital patient have little in common. One is trained to deal with fire and rescue, one swims underwater and one is concerned with either regaining or improving their health. Yet all three depend to some extent on a safe source of compressed breathing air, which is where our gas detection systems come in. ...
