GO AQS – Heike Krüger – Clean Indoor Air is Only Possible with Limits for Invisible Ultrafine Particles PM0.1

Heike Krüger, Chairwoman of the nano-Control, Internationale Stiftung, is sounding the alarm on a „silent epidemic“ hiding in our offices: ultrafine particles from laser printers.

The Invisible Reality:

  • Printing just one page can release billions of particles into the air.
  • These pollutants can reach every cell in the human body, including the brain.
  • Studies show that 90% of affected individuals report respiratory issues.

Heike is calling for international standards to limit these particles to below 1,000 per cubic centimeter, a vital move to protect us in the indoor spaces where we spend 90% of our lives.

„I have a dream that one day the air we breathe indoors will be safe and clean.“ — Heike Krüger

Global Pledge for Healthy Indoor Air

We declare, for the first time as a global community, that clean indoor air is a fundamental human right for protecting health and safeguarding well-being. Poor air quality in indoor environments – where populations spend up to 90 percent of their time – contributes to respiratory disease (including
asthma and lung cancer), heart disease, infectious disease transmission, and cognitive impairment, in addition to potential impacts from carcinogens. All people are impacted by poor indoor air quality.
In 2000, a World Health Organization working group concluded „everyone has a right to healthy indoor air”1 and in recent years, both the United Nations (2022)2 and the World Health Organization (2021)3 recognized clean air as a human right. This Global Pledge builds on those pioneering steps
to help galvanize global action explicitly on indoor air quality. Furthermore, the importance of healthy indoor air is recognized in the context of the United Nations’ Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-Being) and SDG 11 (Sustainable Cities and Communities). Collaboration amongst the broad suite of stakeholders involved in addressing indoor air quality also honors SDG 17 (Partnerships for the Goals).
The 2025 launch of the Global Pledge for Healthy Indoor Air represents a landmark moment, signaling the first international movement to prioritize healthy indoor air for all. We invite governments, non-governmental organizations, cities, universities, schools, healthcare facilities, professional associations, advocacy organizations, businesses, and community groups to join this Pledge. Together, we can build a world where everyone, everywhere, breathes healthy indoor air. Weiterlesen

Die Mauer durchbrechen: Innenluft zählt genauso wie Außenluft!

Unsichtbare Gefahr im Innenraum – Zeit zur Schaffung wissenschaftliche Evidenz zur Luftverschmutzung durch ultrafeine Partikel und deren Wirkung auf die Gesundheit

Seit über drei Jahrzehnten kämpfen Menschen, die von den Emissionen von Laserdruckern und Kopierern betroffen sind, um Anerkennung, Verständnis und Schutz. Was als Gesundheitsbeschwerden Einzelner begann, hat sich zu einem bedeutenden Problem der öffentlichen Gesundheit entwickelt – gestützt durch Daten, Fallberichte und wissenschaftliche Erkenntnisse.

Über viele Jahre hinweg hat sich gezeigt, dass Büroumgebungen, die harmlos erschienen, eine zentrale Rolle bei diesem Problem spielen. Tausende haben sich bei nano-Control, Internationale Stiftung immer wieder mit ähnlichen Symptomen gemeldet. Alle waren den Emissionen aus Bürogeräten, wie Laserdrucker und Kopierer ausgesetzt und sahen dies als die Ursache ihrer Gesundheitsbeschwerden.

Die ehrenamtliche Stiftung nano-Control hat sich von einer Bürgerinitiative zu einer Wissens- und Interessenvertretungsplattform entwickelt. Weiterlesen

Elephant in the room – ultrafine particles and anthropogenic organic aerosols

Origin, effect and health relevance – focus on laser printer emissions

Aerosols – definition and origin in the air we breathe

Aerosols: complex mixtures of solid and/or liquid particles, finely dispersed in a gas – typically air

Formation in the ambient air – indoors and outdoors: both through natural processes (e.g. volcanic eruptions, pollen count, sea spray) and human activities such as industry, transport, laser printing, 3D printing and household processes.

Jahresbericht 2024

Zusammenfassung

Liebe Stifter, Förderer und Paten, liebe Teammitglieder, Freunde und Leser!

In diesem Jahr haben wir einen Meilenstein erreicht. Anonymisierte Daten von 2.000 Betroffenen wurden von der University of Massachusetts wissenschaftlich ausgewertet und bestätigen die Berichte von inzwischen 4.000 Betroffenen. Es kommt zu entzündlichen und immunologischen Symptomen und Erkrankungen durch die Emissionen von Laserdruckern und -kopierern.

Indoor air quality (IAQ): Safe areas with clean, healthy breathing air that we can trust! – An overview

The non-profit foundation nano-Control, International Foundation calls for mandatory rules for the operation of toner-based printing systems „laser printers“ to sustainably improve indoor air quality.

The human right to breathe clean air also applies to the air we breathe indoors.

„Briefing Air quality in Europe 2021 Air pollution is the single largest environmental health risk in Europe and has significant impacts on the health of the European population, particularly in urban areas.“ Source: European Environment Agency (EEA)

The voluntary nano-Control, International Foundation and its previous organization, the ITG citizens‘ initiative, have been working for almost 30 years on a vital issue: protecting the air we breathe indoors, because we need clean, healthy air to breathe. Breathing is living.
