Plant and tree destruction is advancing rapidly across the globe. Theories of causes of this damage include the vapors from the Deepwater Horizon oil spill in the Gulf or Mexico and the Louisiana sinkhole, ethanol combustion from autos, chemtrails, and radionuclides from the Fukushima nuclear catastrophe.
The blue-black spots that frequently occur on the leaves of damaged trees can be explained by the action of iodine on starch in the leaves. When photosynthesis occurs, excess glucose is stored in the leaf in the form of amylose, which is a starch. This stores energy for later breakdown into sugars.
The well-known iodine-starch test is widely used to test for the presence of starch. Iodine in the form of iodide compounds enters the leaf. Most of these compounds are water soluble, so they may be found in rainwater. These iodide molecules fit inside the coils of amylose. In the presence of an excess oxidizing agent, these iodides revert back to elemental iodine inside the coils, and the complex turns blue or blue-black.
So what is happening?
1. Iodine is entering the leaf via rainfall. The iodine may come from the oil fields of Louisiana and the Gulf, or may be produced in the form of radioactive iodine from the ruins of the Fukushima Daiichi nuclear complex.
2. An excess oxidizing agent is also present, in the air from ozone, or in the rain from more water soluble PANs (peroxyacyl nitrates), from the BP oil spill and/or the Louisiana sinkhole.
3. Together they show the blue-black colors where starch is present in the leaf.
There is no easy way to determine how much iodine is coming from the oil disasters in the Gulf area vs. from Fukushima. But it cannot be caused by burning ethanol in cars. It must be coming from one or both of these environmental catastrophes.
