Air pollution is the most-pressing environmental health crisis of our time with approximately nine in 10 people around the world breathing unclean air.
The most recent estimates (2016) obtained by the World Health Organization state that more than 4.2 million people die prematurely annually as a result of long-lasting exposure to fine particulate outdoor air pollution (frequently mentioned as PM2.5).
Government and industry are working together to build a clean and strong economy that supports good jobs and positions Canada as a reliable supplier of energy in a net-zero world. Through continued investments in clean technology innovation, like hydrogen, Canada will remain a leader in this field.
Globally, the coastal lagoons of Lagos (Nigeria), Sakumo (Ghana) and Bizerte (Tunisia) --close to large urban centres and without waste and sewage treatment systems-- are among the most affected water ecosystems of this nature by microplastic pollution.
Researchers in Ehime University (Japan) investigated the contamination levels and composition profiles of halogenated and phosphorous flame retardants in settled dust from informal waste processing sites in Vietnam, and detected the emerging flame retardants organophosphate esters (OPEs) at higher concentrations than those of the legacy brominated flame retardants (BFRs) in the end-of-life vehicle (ELV) processing site.
In Singapore, small particles in air pollution may have resulted in sudden cardiac arrests in a few people who were not in the hospital but just going through their normal lives, as per researchers at Duke-NUS Medical School collaborating with the National Environment Agency (NEA) as part of the Pan-Asian Resuscitation Outcomes Study (PAROS).
Scientists and collaborators from Karlsruhe Institute of Technology (KIT) doubt that a high number of plastics has been transported in flowing waters compared to what was thought earlier and are currently developing new modeling approaches.
Carbon emissions from lakes, rivers, and reservoirs include a huge proportion of the carbon cycle worldwide. New studies on carbon release from inland waters in China have concentrated on single rivers or lakes, and the fundamental factors driving carbon dioxide (CO2) emissions remain vague.
One of the most notable climate change provisions in the 2022 Inflation Reduction Act is the first U.S. federal tax on a greenhouse gas (GHG). That the fee targets methane (CH4), rather than carbon dioxide (CO2), emissions is indicative of the urgency the scientific community has placed on reducing this short-lived but powerful gas.
The Plasticker project has been initiated by scientists to provide comprehensive information on the presence of microparticles in cities.
