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

The air we breathe indoors can be far more polluted than the air outside, yet it’s an issue that often goes unnoticed. The nano-Control, International Foundation and the Global Open Air Quality Standards (GO AQS) initiative are stepping up to address this critical challenge by announcing a new collaboration focused on the health risks posed […]

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.

The non-profit organisation nano-Control, International Foundation calls for mandatory rules for the installation and operation of ubiquitous toner-based printing systems like ‘laser printers and copiers’ to sustainably improve indoor air quality. The ban on inhalable PFAS in indoor environment is necessary.

The non-profit nano-Control International Foundation advocates for strict regulations on indoor air quality and stricter control over the installation and operation of toner-based devices, such as laser printers and copiers. Achieving high standards in indoor air quality is essential to protect public health and minimize exposure to harmful pollutants.

Over the course of many years, the International nano-Control Foundation (iNCF) used a detailed questionnaire to carefully and systematically collect information about health symptoms and exposure conditions of office employees who believed to be exposed to printers and photocopier machines in Germany. The data were collected between 1999 and 2010 from at least 2000 participants.  After no one in Germany showed any interest on such data for many years, in 2021, a team of researchers from the US University of Massachusetts Lowell in the College of Health Sciences, led by Profs. Dhimiter Bello and Anila Bello, systematically analyzed the data and published the results in the Journal of Occupational and Environmental Medicine[1]. Dr. D Bello’s group has been investigating the chemistry and toxicology of nanoparticle emissions from printers and photocopiers for many years.

The current paper documented that workers who stated that they were exposed to particles from these machines, including copy and printer machine operators, technicians, and office workers, also reported high frequencies of respiratory diseases (90% of 1998 respondents), allergies (70% of respondents), as well as other health symptoms or diseases, including  asthma/Chronic  Obstructive Pulmonary Disease (COPD, 15% of respondents), bronchial hyperreactivity, cardiovascular disease, neurological disorders, metal allergies (nickel and cobalt), gastrointestinal disorders, and some cancers. The researchers found that half of the workers reported that their acute respiratory and skin conditions improved significantly away from work (e.g. on the weekend or holidays) and worsened when returning to work, indicating an important role of workplace exposures on the reported symptoms.

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.

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.
