What Is Particulate Matter?

The American Lung Association has published an insightful article about particulate matter (PM) that explains the topic well. Particulate matter consists of tiny particles such as dust, dirt, soot, smoke, and liquid droplets. While some particles are visible, many require a microscope to be seen. PM is categorized by size: larger particles are called PM10, while finer particles are known as PM2.5, which pose the greatest health risks.

Sources of Particulate Matter
Particulate matter comes from various sources, including:

• Cooking: Frying, grilling, or using gas stoves.

• Combustion Activities: Smoking, burning candles, and using fireplaces.

• Household Products: Cleaning agents, air fresheners, and aerosol sprays.

• Hobbies: Woodworking, metalworking, and crafting.

• Biological Sources: Mold spores, dust mites, and cockroaches.

• Outdoor Air: Vehicle emissions, wildfires, and industrial activities. Particle pollution can enter buildings through windows and ventilation systems.

Health Impacts of Particulate Matter
Inhalation of PM2.5 can penetrate deep into the lungs, causing irritation and exacerbating conditions like asthma and COPD, as well as leading to pneumonia, heart disease, stroke, and lung cancer.

Sensors like Decentlab's DL-PM | Particulate Matter, Temperature, Humidity and Barometric Pressure Sensor for LoRaWAN® and DL-IAM | Indoor Ambiance Monitor including CO₂, TVOC and Motion Sensor for LoRaWAN® help keep air quality in check, ensuring safer air for all.

Groundwater: Alarming Trends and the Need for Monitoring

In many parts of the world, alarming trends in groundwater are being observed as water levels dramatically decline in numerous regions. An analysis by CORRECTIV highlights concerning data for Germany: over a span of 32 years, groundwater levels have generally decreased more than they have increased.

The primary causes of this decline are human activities, particularly water extraction by industries, agriculture, and mining, which lead to water scarcity and conflicts over water resources. The lack of transparency regarding groundwater levels is exacerbated by the absence of standardized data collection. Additionally, the climate crisis intensifies the situation by hindering groundwater replenishment and increasing water demand.

To better understand this critical situation, CORRECTIV has developed an interactive map that provides an overview of groundwater level trends in Germany, based on data from approximately 6,700 measuring points. This map illustrates the alarming trends of recent decades.

Moreover, it is once again evident how essential data collection and long-term measurements are. Environmental sensors like the DL-PR26 and DL-PR36 facilitate continuous monitoring, providing valuable real-time data to swiftly respond to changes in groundwater levels.

Experiment investigates Air and Soil Dryness in Forests

The remarkable installation in the Pfynwald forest in Valais, Switzerland, is part of the globally unique “VPDrought” experiment, designed to unravel the effects of soil and air droughts in a natural forest ecosystem. This study explores how both air and soil dryness impact mature forest pines. The 130-year-old trees receive varying amounts of soil water, and high-pressure nozzles in some of the canopies spray water vapor during the day to reduce the vapor pressure deficit (VPD) by about 20 to 30 percent.

Our client and partner, WSL (Swiss Federal Research Institute for Forest, Snow and Landscape) and EPFL, are examining how these conditions affect tree resilience and dieback processes. The experiment will evaluate the effects of soil and air drought on plant physiology and ecosystem health. It will offer valuable information for developing future climate models and forest management strategies.

Like a Sponge: Could this be the Future of Urban Water Systems?

A sponge city is an urban concept designed to make cities more resilient to floods and extreme weather events. The city functions like a sponge, absorbing rainwater, storing it, and slowly releasing it. This is achieved through permeable surfaces, green spaces, green roofs, and rainwater storage systems, which together reduce the risk of flooding and improve water supply during dry periods. National Geographic explains this concept in an engaging and insightful article.

Environmental sensors are crucial in sponge cities, as they monitor key parameters such as soil moisture, rainfall, and water levels in real-time. For instance, Decentlab’s DL-SMTP sensor measures soil moisture and temperature, while the DL-PR26 tracks ground water and water levels, and the DL-MBX provides ultrasonic distance and water level measurements. These sensors help optimize water absorption and storage, prevent flooding, and ensure water and air quality. This continuous data collection enables better planning and adaptation, enhancing the resilience of sponge cities to climate change impacts.

Heat Islands & Cooling Strategies

What are Heat Islands?
Heat islands are urban areas where buildings and roads absorb and re-emit more heat than natural landscapes, causing higher temperatures.

Causes of Heat Islands

• Reduced Natural Landscapes: Less vegetation means less shading and cooling.

• Material Properties: Asphalt and concrete retain more heat.

• Urban Geometry: Dense buildings restrict airflow and heat dissipation.

• Human Activities: Vehicles and air conditioning add extra heat.

• Weather and Geography: Clear, calm weather intensifies heat islands; wind and clouds lessen them.

Cooling Strategies for Heat Islands

• Increasing Vegetation: Adds shading and cooling.

• Green Roofs: Reduces roof temperatures and improves stormwater management.

• Cool Roofs: Reflective materials lower roof temperatures.

• Cool Pavements: Heat-absorbent materials on sidewalks and streets.

• Smart Growth: Development that enhances environmental quality and livability.

Recent Storms and Floods: Enhancing Resilience

The recent floods and severe weather in Switzerland and neighboring countries have deeply saddened us and tragically claimed several lives. According to a meteorologist from SRF Meteo, moist air masses in the southern Alps and a cold front over Switzerland may have played a role in these events, while saturated soils from previous rains may have facilitated landslides. It would seem that such events are becoming more frequent and intense as a result of climate change.

Our client and partner, the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), addresses questions about these weather events and emphasizes the crucial role of advanced technologies in timely data capture and provision. Sensors like the DL-MBX | Ultrasonic Distance / Level Sensor for LoRaWAN® have been specifically developed for flood monitoring and water level measurement. They are indispensable for early warning systems, providing precise data to assess risks and protect residents and their surroundings.

See the Air – Mass vs Particle Number

Traditionally, air quality has been monitored by measuring the mass concentration of particles (PM), i.e., the total mass of particles per unit volume of air. However, this method is insufficient for submicron particles (diameter < 1 micrometer). These tiny particles are numerous, but their low mass might obscure the health risks.

A better method is to measure the particle number by size distribution. This provides important insights, as different sources produce different particle sizes.

Advantages of Particle Size Distribution:

• Source Identification: Differences in particle sizes help identify emission sources (e.g., vehicles, industry).

• Targeted Regulations: Regulations can be designed to address specific particle size ranges associated with health risks.

• More Effective Monitoring: Monitoring can focus on the most hazardous particle types.

Sensors like the DL-PM, which transmits particulate matter measurements along with temperature, humidity, and barometric pressure data over LoRaWAN®, enable researchers and decision-makers to gather valuable insights.

Growing Flood Risk

Massive floods occurred in Germany and other parts of Europe in early June. The Süddeutsche Zeitung addressed the increased occurrence of intense rainfall and flooding, driven by climate change. Warmer air can hold more moisture, leading to heavier rainfall, while rising temperatures provide more energy for extreme weather events.

The Intergovernmental Panel on Climate Change (IPCC) warns of growing flood risks in Europe. Thanks to modern sensor technology, prediction accuracy has improved, enabling early evacuations. Adaptation measures such as expanding flood protection and early warning systems have already reduced fatalities.

Nature-based solutions, such as the restoration of floodplains and reforestation projects, play a crucial role in mitigating the effects of floods. However, construction continues in flood-prone areas, exacerbating risks. Over 1,000 new houses are built in such zones annually, despite 300,000 buildings already being threatened. It is urgently necessary to develop long-term solutions that consider climate change and prevent future disasters.
