A new device for measuring air pollution has been developed in Brazil and will be installed on indigenous territories. The technology was created in partnership between the Amazon Environmental Research Institute (IPAM) and the Federal University of Para (UFPA), as reported by Brasil de Fato, a partner of TV BRICS.
The device measures temperature, humidity, and pollution levels every two minutes. It is capable of detecting the tiniest PM 2.5 particles (microscopic airborne particles, both solid and liquid, invisible to the naked eye – Ed.), which are ten times thinner than a human hair. These tiny particles can penetrate deep into the lungs and enter the bloodstream. In the long term, they can lead to the development of respiratory and cardiovascular diseases.
The equipment is low-cost and manufactured entirely domestically. Plans are in place to integrate air quality data with records of consultations at the Special Secretariat for Indigenous Health (SESAI) and the health monitoring system. Such analytics will help government bodies update existing health programmes.
IPAM researcher Filipe Viegas Arruda, who is responsible for the development, notes that the equipment helps to obtain objective data on air quality in the region. Unlike large cities, where the main source of pollution is cars, in the Amazon, air quality is influenced by natural processes.
There are currently around 570 air quality monitoring stations operating in Brazil, 12 of which are located on indigenous territories.

Ashok MondalNID Director"Signing this Memorandum of Understanding between the National Institute of Design (NID) and TV BRICS marks a pivotal milestone in advancing design diplomacy across the BRICS media space. This moment is especially significant as India hosts the 18th BRICS Summit, following India’s assumption of the BRICS chairship under the visionary leadership of Prime Minister Shri Narendra Modi. The partnership directly embodies his call to elevate Indian design standards through 'Design in India, Design for the World'. Through the global reach and broadcast capabilities of TV BRICS, we are excited to showcase the extraordinary visual storytelling, films, and design research of NID’s Film and Video Communication students to an international audience, while also welcoming and screening film works from BRICS network countries at NID Ahmedabad. This reciprocal exchange strengthens our shared commitment to educational, cultural, and artistic collaboration, fostering sustainable connections among global creative communities. NID Ahmedabad looks forward to leveraging this partnership to deepen cross-cultural dialogue, build international expert networks, and unlock transformative opportunities for filmmakers, researchers, and faculty across member nations" -

So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification" -
