Mandatory standards for the indoor environment would result in immense benefits to the health and productivity of people around the world

TU Delft researchers participate in landmark Science paper on indoor air quality

2024-03-29
(Press-News.org) This publication is a call to action for governments and agencies to develop, legislate and enforce IAQ standards. Boerstra: “Traditionally, governments have regulated outdoor air. But inhabitants of industrialized countries now spend more than 90% of their time indoors.” As a result, indoor pollutants have major consequences for our long-term health. Bluyssen: “For example, we now know that tiny airborne particles can pass directly from lungs to bloodstream, where they cause all kinds of diseases.” And indoor air is also a prime transmitter of pathogens, as demonstrated by the COVID-19 pandemic.

Quote: Governments have regulated outdoor air, but [we] now spend more than 90% of our lives indoors - Boerstra

Where to start

According to the authors, initial regulations should focus on pollutants which are relatively easy to measure and indicate broader health concerns. PM2,5 (airborne particles) fit these criteria, while monitoring levels of CO (carbon monoxide) remains vital in developing economies. In addition, a high indoor CO2 level indicates overcrowding and a lack of ventilation, and thus an increased risk of spreading pathogens. Ventilation is a vital countermeasure, augmented by filtering and cleaning technology where necessary. Boerstra points out: “Due to poor outside air quality in many cities, mechanical ventilation will remain essential.” And Bluyssen: “The type of ventilation is critical. Displacement ventilation for schools, personal ventilation for offices… just opening a window is not good enough.”

The hurdles to overcome

The authors point to several challenges in enforcing IAQ standards. For example, a main source of indoor pollutants is human breathing, which is difficult to control. Monitoring IAQ is also highly complex, since every room serves a different function and thus has its own difficult-to-predict fluctuations in pollutants. And new regulations will always be resisted by industries who incur costs or require strategic change. Boerstra: “For example, the recommended level of ventilation for existing nightclubs and cafes is currently set at 2.1 litres of clean air per person per second, even though the World Health Organisation recommends at least 10 to avoid infections.” Finally, the authors acknowledge that IAQ standards may have economic, cultural, and political implications for certain regions. In such cases, compromises might be unavoidable.

Quote: The type of ventilation is crucial… just opening a window is not good enough - Bluyssen

The time to act is now

While these obstacles are acknowledged, the paper asserts that the benefits of IAQ standards will far outweigh the costs. Data clearly show the devastating effects of air pollution on the financial and physical health of society, and the authors are fighting those effects. Philomena Bluyssen is part of the Pandemic & Disaster Preparedness Centre, the programme P3Venti (Pandemic Preparedness and Ventilation), and a national project on mobile air cleaners at schools. Atze Boerstra is part of the nationwide collaboration MIST (Mitigation Strategies for airborne infection control). “And I am a member of NEN and CEN indoor climate committees, which influence policy across Europe.” Therefore, this Science publication reflects the ongoing efforts of Bluyssen, Boerstra, and their 37 colleagues to develop technology, research air quality, and advocate for IAQ standards.

Chickadees have unique neural “barcodes” for memories of stashing away food

Chickadees have unique neural “barcodes” for memories of stashing away food
2024-03-29
Your ability to remember and recall moments in time is important for recording life-defining moments and everyday information like where you parked the car. Now researchers reporting in the journal Cell on March 29 have new insight into how those episodic memories are encoded in the brain based on studies of how chickadees store food. Their study finds that chickadees activate unique neural patterns, which they liken to barcodes, each time they cache food in a certain spot. When they go back to retrieve that stored food, their brains light back ...

Chickadees are memory geniuses. Their barcode-like neural activity may be to thank

2024-03-29
NEW YORK, NY — Black-capped chickadees have extraordinary memories that can recall the locations of thousands of morsels of food to help them survive the winter. Now scientists at Columbia's Zuckerman Institute have discovered how the chickadees can remember so many details: they memorize each food location using brain cell activity akin to a barcode. These new findings may shed light on how the brain creates memories for the events that make up our lives. "We see the world through our memories of objects, places and people," said Dmitriy Aronov, PhD, a principal investigator at Columbia’s Zuckerman Institute and an ...

2024-03-29
Researchers Yuta Sunakawa, Ko Mochizuki, and Atsushi Kawakita of the University of Tokyo discovered the first orchid species pollinated by gall midges, a tiny fly species. This is the first documented case of an orchid species found to be pollinated by gall midges, and it makes the orchids the eleventh such plant family. The findings were published in the journal Ecology. The family of orchids is rich both in numbers and variety. Their range of shapes and sizes is due to having evolved to attract different animal pollinators. However, scientists have only mapped ...

Scientists discover a key quality-control mechanism in DNA replication

2024-03-29
PHILADELPHIA – When cells in the human body divide, they must first make accurate copies of their DNA. The DNA replication exercise is one of the most important processes in all living organisms and is fraught with risks of mutation, which can lead to cell death or cancer. Now, in a landmark finding, biologists from the Perelman School of Medicine at the University of Pennsylvania and from the University of Leeds have identified a multi-protein “machine” in cells that helps govern the pausing or stopping of DNA replication to ensure its smooth progress. The discovery, published today in Cell, advances the understanding of DNA replication, helps explain ...
