matter from wildfire smoke can be more harmful than pollution from other sources

University of California - San Diego. "Fine particulate matter from wildfire smoke more harmful than pollution from other sources: Researchers call for revisions to air-quality monitoring guidelines to consider the sources of emissions." ScienceDaily. ScienceDaily, 5 March 2021. <www.sciencedaily.com/releases/2021/03/210305080124.htm>.


       Researchers at Scripps Institution of Oceanography at UC San Diego have been examining the data of hospital admissions from the past 14 years. They can conclude that the fine particles in wildfire smoke can be several times more harmful to the lungs of humans and other animals, than particles of matter from other sources, such as car exhaust or other gas appliances. While there have been many laboratory experiments, the new study confirms it at a population level. Wildfire smoke can penetrate the human respiratory tract and can enter the bloodstream or impair vital organs. To isolate wildfire-produced PM2.5 from other sources of particulate pollution, researchers defined exposure and are comparing it to the strong Santa Ana winds with fire upwind.

    This is surprising to me since I would've assumed that man-made pollution would be more harmful due to all the chemicals we've created. But this just further shows that we need to be careful about how we use our resources so that we can try to prevent large wildfires. Unfortunately, I'm sure we'll have plenty more thanks to climate change, but we should do all we can to reduce damage for the sake of the environment & our lungs.

Dual-fuel vehicles

A recent study shows that dual- fuel vehicles are benefiting the population but, turns out they are costing the environment. While substituting gasoline for ethanol gases, it causes an increase of ultra fine particle matter, with a 30% increase of atmospheric concentration. The problem is that they are less then 50 nanometers in diameter. The nano particles are also not track or regulated by the environmental agencies. We inhale these gases everyday, inhaling ethanol. The most practical way to reduce greenhouse gases is using electric, hybrid and biofuel care.   https://www.sciencedaily.com/releases/2017/08/170828124546.htm

Acid Zone in Chesapeake Bay Found

     According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
