The effects of DDT traumatic at high doses, while DDT doesn't cause polio but it is a possible carcinogen, thanks to biomonitoring studies which help to keep track acceptable levels in blood serum, but due to legislation the levels are far lower than in the 70's. #geochemchat

@HalCranmer @crypto_foxtrot @cliftonaduncan Try the toxicology reports, look for instances of poisoning, study the medical journals.

Lead poisoning is well documented. DDT poisoning is well documented, as is polio.

An overlap of U-Pb & U-Th dating,overcomes a significant barrier to dating Iron ore. This method accounts for Iron that emerged from tectonic plate continental separation due to the heat associated. Where only 1 type wouldn't account for the chronology and origin. #geochemchat

Funny enough, Mars volcanic geochemical character has been shown to differ from earth. K and Th are radioactive markers at volcanoes, as they emit gamma rays. However K and Th are found in very low amounts on Mars, the suspicion is a depletion over years of eruption. #geochemchat

Correlation between how anthropogenic activities can affect forest structure. Different species are now replacing original mangroves, these are now resistant to saltiness and low levels of Oxygen caused by pollution, these species derive nutrients from our pollution. #geochemchat

U and Th impact, was studied and the results on ants and their nests with soil which is affected by Uranium due to soil erosion overtime, from the bedrock that contains U and Th . Ants with high Uranium content displayed a "lustre- like" blue colour on their cuticles.#geochemchat

Something health related for a change, would be interesting to do ICP-MS a for this. This article shows how the Potassium Isotopes that are linked to proteins that cause AD appear in the blood, suggesting a migration from the brain when the proteins aggregate. #geochemchat

[James Cook Uni @jcu]

New research from a JCU-led study has proposed a hypothesis that higher levels of certain potassium isotopes (atoms) in a person’s bloodstream could be a way of detecting Alzheimer’s Disease much sooner than current methods allow.

Fascinating read on how wild fires, due to climate change can increase metal concentration in streams. While most elements may not be seriously harmful to life, but what if more toxic trace metals were washed into a stream after massive fires? #geochemchat

Interesting how isotopic data between different volcanic deposits can have a tight similarity in lead content, meaning the rock chemistry is still preserved in spite of erosion and distance. I wonder what type weathering processes would tamper with isotope abundance #geochemchat

[USGS Volcanoes🌋 @USGSVolcanoes]

Geologists are like detectives—they use a variety of investigative tools to understand how a landscape develops. Today, #Yellowstone #CalderaChronicles explores how geochemistry can link volcanic deposits to their sources, even over great distances.
