BASF introduces cost-effective upgrade to ozone-VOC converters for healthier aircraft cabin air; UpCore

Green Car Congress

BASF has launched UpCore, a new service providing a cost-effective and sustainable technology upgrade from a standard ozone converter to an ozone-VOC (volatile organic compounds) converter for cleaner and healthier aircraft cabin air. The air at high altitude contains significant levels of ozone.

Studies find global COVID-19 lockdowns have significantly reduced PM2.5 and NO2 pollution, but ozone up

Green Car Congress

Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Ozone is harmful to humans at ground-level, causing pulmonary and heart disease. —Guy Brasseur.

A team from Rice University and the Houston Fire Department EMS has found a direct correlation between out-of-hospital cardiac arrests (OHCA) and levels of air pollution and ozone. micrograms) and ozone. For the study, OHCA events were defined as cases where EMS personnel performed chest compressions. Katherine B.

EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

Researchers discover that a ubiquitous tire rubber–derived chemical is killing coho salmon in urban waterways: 6PPD-quinone

Green Car Congress

For decades, researchers have observed regular acute mortality events affecting adult coho salmon ( Oncorhycchus kisutch ) that migrate into urban waterways contaminated with stormwater runoff. Ozone breaks the bonds holding the tire together. 6PPD reacts with ozone before it can react with the tire rubber, sparing the tires.

6PPD-quinone derived from tire debris is toxic to two trout species, not just coho salmon

Green Car Congress

6PPD is an antioxidant and antiozonant that helps prevent the degradation and cracking of rubber compounds caused by exposure to oxygen, ozone and temperature fluctuation. They found that even small concentrations, such as those regularly occurring in surface waters after stormwater runoff events, were fatal to brook and rainbow trout.
