Canadian Lakes still have traces of dangerous pesticide decades later

In the 70's, planes dropped the DDT pesticide, which is now banned, in an effort to combat spruce budworm outbreaks in New Brunswick, Canada. Now decades later, researchers have found traces of the pesticide in some mud samples taken near lakers in the province. While not harmful to humans at the levels found, it is still jarring to think that nearly 50 years later a banned substance could still be found in the environment.

    This is quiet interesting because of the length of time the pesticides have been in the environment. Does this mean that the amount was at a dangerous level for animals and humans in years before? I'm also curious as to what the effects the pesticides had on local species?

    This is alarming since there is legislation at the moment trying to lift the bans on previously banned pesticides. 50 years is a long time, and to still have the affects lingering around is quite disturbing. Which raises the question of how much research should go into the making/ use of pesticides before they are implemented into everyday farming along with what are the effects on the environment in countries that do not have any regulations on pesticides.

    This is very interesting since this pesticide hasn't been used for over 50 years. Could this be harmful to humans in any way in the future if the levels rise, or is it harmful to any other animals or creatures?

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
