Researchers at the University of Basel have investigated how fine particles in exhaust emissions from aircraft and marine engines change in the atmosphere. Their findings show that aircraft emissions in particular become more toxic over time.
Fine particulate matter consists of tiny particles with diameters in the nanometer range. They are produced, for example, by fuel combustion, remain suspended in the air and can penetrate deep into the respiratory tract. There, they can trigger what is known as oxidative stress – a process that promotes inflammation and, in the long term, can lead to serious health problems such as respiratory or cardiovascular diseases. Scientists refer to this harmful property of the particles as their oxidative potential.

Patient-centered financial navigation assistance helps reduce financial toxicity among cancer patients - Medical Xpress
Among cancer patients, the high financial cost of cancer care is a prevalent problem. This financial burden is also associated with potentially harmful behavioral strategies that patients might use to cope with costs, such as delaying or forgoing treatment and skipping medications. Collectively, researchers refer to this impact as financial toxicity.
Northern Health region continues to see province’s highest drug toxicity death rate, new data shows - CJDC-TV
October 14, 2026 at 2:50p.m. EDTFORT ST. JOHN, B. C. - Preliminary figures from the BC Coroners Service show unregulated drug toxicity deaths increased in August, with 126 deaths recorded across British Columbia compared to 113 in July. The latest reporting found an average of 4.1 deaths per day in August, up from 3.6 deaths per day in July. The report also found Northern Health continues to have the highest rate of unregulated drug toxicity deaths in the province in 2026, at 43 deaths per 100,000 people. In July, 5 people died in the Northern Health region due to overdose. In September, that number climbed to 13. Island Health recorded the second-highest rate at 34 deaths per 100,000 people. Across July and August, 239 people died in B. C. from unregulated drug toxicity. Of those, 188 were male and 51 were female. Men account for 76 per cent of all unregulated drug deaths reported so far this year. People between the ages of 30 and 59 continue to be the most affected group, accounting for 69 per cent of drug toxicity deaths in B. C. during 2026.
