Bedside Water Taste & Chemistry

Have you ever noticed that the water tastes different when you leave it in a glass on your nightstand overnight?

In general during the 8h sleep, CO2 is built inside the room. Especially in winter when we don’t ventilate as frequent and CO2 can reach levels higher than 2,000ppm inside the house. CO2 is a soluble gas and water is the perfect solvent. As a result a process called Acidification is occurred naturally and the PH lowers during that process. That gives your bedside glass of water a horrible taste.

OK Lab Stuttgart – PM DIY Monitor

An Outdoor PM DIY Monitor

Do you think the current PM (Particulate Matter) monitors are too expansive or too risky to leave them outside? Do you need proofs for convincing your local authorities to take actions against air pollution?

Then it’s time to build your own personal outdoor PM DIY Monitor. It won’t cost you more than €32 and it can feed your community with valuable data about the air quality. Use that data to prove how bad is the air quality in your neighborhood or community.

The Air in New York

In my recent visit in New York and in other USA cities I decided to take with me a portable carbon monoxide device and measure the air quality across the cities during my trip.

The CO Sensor was placed on a net pocket that I had sewed on my backpack. I am quite the craftsman! The experiment had to be done correctly to ensure that the air flowed easily and the measurements were taken correctly and constantly.Read More »

Review: Cambridge Mask

This time I had the opportunity of getting a half face mask by Cambridge Mask Co. and of course I wrote with pleasure a review on my blog.

Characteristics

Cambridge Mask offers the N99 respirators (Not oil resistant), a three layer mask with a Military Grade Carbon Filter layer, and the Three-Ply Micro Particulate layer. An exhale valve is present as well to ensure that moist won’t build up.  These respirators also filter 99.6% of viruses and 99.77% of bacteria.Read More »

Exhaust Smoke Colours and Pollutants

Did you know that cars emit smoke with a differnt colour depending the engine that they use and the problems that they are having. Here are the following categories: Blue smoke, White smoke and Black smoke.

Untitled

Blue Smoke

Blue smoke means your engine is burning oil. Oil is an important element in the engine, but only to lubricate the moving parts. When it is burnt by the engine means that there are leaking valve seals or worn piston rings or worn cylinder walls. In this case large quantities of Carbon monoxide CO, PMs, NO2 and SO2 are released into the environment.

White Smoke

There are two types of white smoke, the normal white vapor that disappears quickly under normal conditions due to condensation and the heavy white smoke. The heavy white smoke must concern you because the coolant has made its way into the combustion chamber. In this case large quantities of VOCs and PMs are released into the environment.

Black Smoke

Finally the black smoke indicates that your air/fuel mixture is running rich. Which means that more fuel is entering the engine and it doesn’t burn completely due to the lack of the air or oxygen. This is also called rich. When more air enters the engine than fuel this is called lean. In this case large quantities of CO, PMs and NO2 are released into the environment.

Conclusion

All in all, the emitted smoke from the exhaust may not tell you the exact problem, but it can give you an idea of what the problem of your engine is and the pollution that is emitted. Visit your mechanic immediately, public health may be in jeopardy.

Ozone O3 an Air Pollutant

The Ozone O3 is protecting us through the Ozone Shield from the harmful ultraviolet UV radiation when it is in the lower portion of the stratosphere at 20km to 30km above Earth. However it is a harmful gas for the respiratory system and it can cause serious health issues when it is inhaled in high consecration.

As a result we divide the Ozone in two categories, the Ozone Shield aka Good Ozone and the Ground Level Ozone aka Bad Ozone. Basically the Ground level Ozone is formatted by a combination of gases and the Sunlight.

VOCs + NOx + Heat + Sunlight = Ozone

 Breathing ozone O3 can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma. Ground level Ozone can also have harmful effects on sensitive vegetation and ecosystems.
