Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous.

According to a current study conducted by the Max Planck Society, worldwide 3.3 million people annually die prematurely due-to consequences of air pollution. In the European Union, the exposure with fine dust and ozone causes up to 180 000 deaths each year, of which alone 35 000 die in Germany. (Source) Various examinations have proven that dust polluted air indoor and outdoor damage the heart, lungs and brain resulting in an increased infarction and stroke risk and rising attacks of asthma. At the latest since the Volkswagen emission scandal and the fine dust alert in Stuttgart, the topic gained presence. It is a fact that the emission of fine dust and nitrogen oxide in exhaust gases is not entirely caused by road transport vehicles. Not only in Stuttgart, but also in other areas in Europe the particulate matter concentrations are too high. Also tyre abrasion on the roadway as well as aviation and railway related PM2.5 emissions contribute to a rising fine dust concentration in the environment. The promotion of small-scale firing plants in recent years intensified the problem and demonstrates nowadays its full impact. Biomass power plants and industrial incinerations were the main emitters of fine dust particles.

European emission limits and emission guidelines should control the respirable dust pollution. Since 2015 exist a limit value of 25 µg/m³ in the annual average throughout Europe. This value will be reduced in 2020 to 20 µg/m³. The conformation of the limitation values were controlled by 170 regulatory measuring stations of the Federal Environment Agency in Germany. According to their results, the fine dust pollution has diminished over the last few years at both national and regional level, but the trend stagnated since 2013. (Source)
Comprehensible to everyone is that fine dust pollution rises in urban and suburban spaces, whereas in rural areas the values decrease.
To combat causes is more difficult than the responsible persons thought.

No matter what the weather is like: The fine dust measurement fits

Weather-related influences adversely affect the measurement. Regulatory measuring stations, as required to gain reliable measuring values, are technically sophisticated and cost-intensive. Currently six regulatory measuring stations in Stuttgart were installed.

Through the compact fine dust sensor FDS 15 from Dr. Födisch Umweltmesstechnik AG, a smart fine dust measuring instrument enters now the market that determines the fine dust concentration (PM2.5) in a similar way. Previous trials in Germany and China correspond well to the regulatory measuring stations. Every two seconds, a measuring signal is transmitted to the receiver. Depending on the customers’ requirements the determined values can be averaged over minutes or hours. Due to the continuous measuring principle, the values contain a high level of information density and have therefore also a great expressiveness.

Moreover, through the WLAN-capability and the connection of several sensors, it can be defined precisely, where and when the fine dust pollution comes from. This is shown by the evaluation of our test results.”

Habits that are bad for your indoor air quality

5 Habits that are bad for your indoor air quality

“School is starting, but warm weather means we are still spending more time outside and keeping windows open as much as possible. However, it doesn’t mean we are safe from poor indoor air quality at home. In fact, indoor air may be more polluted in the summer months than in the wintertime. The reasons include high humidity, pollutant buildup, pesticides and VOCs.

There are certain habits in particular that put our health and well-being at risk in the summer and fall, but awareness and a few tweaks in these habits can help combat poor IAQ this time of year.

Forgetting to Monitor Humidity

In winter, it’s easy to take an interest in humidity levels, since low humidity could lead to nasal irritation and discomfort. In the summertime, humidity is often high and can make its way indoors through open windows and cracks in the building.

The problem is that high levels of humidity can lead to mold growth and a multitude of health problems. It often starts in the basement, where cold walls react to warm air or saturated soil around the home, which leads to condensation and increased humidity.

Humidity levels should stay between 40-60% in the summer, and they should not get much higher than 60% before mold growth becomes a concern. Most homes need a dehumidifier in the basement to regulate humidity, but increased air circulation and monitoring also help.

Slacking Off on the Regular Cleaning Schedule

Hey, we get it, everyone is busy, and cleaning sometimes takes a back seat to hanging out with friends, getting some exercise or attending an outdoor event. But it might be a good idea to keep vacuuming and mopping regularly. Going in and out many times throughout the day means more dirt ends up inside, pets shed just as much as usual (if not more) and dust mites also like to multiply in these conditions.

Going Overboard with Renos and Projects

During the spring, summer and fall, many people move homes or start on a renovation or restoration project close to their heart. And warmer months are great for these activities, as many projects can be done outside or with open windows to maximize ventilation and to minimize exposure to harmful chemicals. Still, taking on too much could wreak havoc with the indoor air quality, and poorly planned projects also bring more headaches than joy. Focus on one project at a time, include the weather forecast in your planning and buy the least harmful products possible.

Leaving the A/C on Continuously

If you are living in a warm region, constant high temperatures are worrisome and can lead to heat exhaustion or heat stroke, but leaving the air conditioning running all the time is also problematic. That’s because when the A/C is on, windows stay shut, and pollutants from everyday products and building materials as well as those brought in from outside remain trapped indoors, building up to unhealthy levels. It’s much better to run the air conditioning during the hottest hours in the day and to open windows at night for optimum air circulation.

Using Pesticides to Combat Bugs

Warmer temperatures mean more insects – a common complaint during the summer – and they like to find their way indoors during fall. Mosquitoes, flies, spiders, ants, and co. will make their appearances, wanted or not. But spraying pesticides is not a good idea, as these chemicals are not only harmful to insects but also to humans, and children in particular. Using screens in windows and on patio doors helps to keep bugs out. Boric acid can help combat ants in the home, and it’s much safer than chemical pesticides.

Try natural bug sprays with citronella and essential oils of lavender, thyme and mint to keep bugs away. Certain plants around the doors and deck can also help: Basil, lemon balm, lemongrass, lavender, rosemary and marigold, for example.”
