@Witsgeochem It would also be interesting to see if the amount of plastic present in people can be related to the amount of plastic pollution in specific areas of the world #geochemchat

[greyling_wits @greyling_wits]

@Witsgeochem It would be interesting to see if age has an effect on how much plastic is present in the body. Like the older you are, the more plastic is present? It would also be interesting to see where (and if) the plastic accumulates #geochemchat

Check out this interesting article on how forensic scientists use IRMS to analyse explosives. #geochemchat. https://t.co/tUA7oekdSb

@geo_mvna An example of using plants to extract heavy metals is sunflowers! Sunflowers are used to extract heavy metals like Cd, Ni, Pb and Zn from the ground. Another example is lettuce. Lettuce removes Pb, Cu and Zn specifically. #geochemchat

@Witsgeochem This is really sad 😔. A solution for the plastic problem must be found soon. Not just for South Africa, but everywhere in the world #geochemchat

@tsutsu1632 @Witsgeochem It would be very interesting to see if the bacteria can absorb other heavy metals and not just uranium #geochemchat

@JasonIsotopes @Witsgeochem @jgchopcraft It’s very interesting that isotopes can be used to compare different animals on the basis of trophic positions, proximity to oceans and geolocation! #geochemchat

Check out this interesting article highlighting some applications of radioisotopes in diverse fields. I found the section about radioisotopes and agriculture very interesting! https://t.co/KldHXqbD0U. #geochemchat.

They used argon-argon dating to date Lucy’s skeleton. The skeleton was too old for radiocarbon dating. Radiometric dating puts pieces of the past in context. Here’s how https://t.co/P6A8vH4j2o #geochemchat

@KLSDM23 @Witsgeochem The aim is to decrease the demand of the rhino horn internationally and to make it more detectable across borders. So why will it be in less demand? What changes to make it less wanted? Easier detection methods has never stopped thieves. So why would this? #geochemchat

@Rethabile2892 @Witsgeochem I think this is a good possible option to generate energy. But one should also consider the health effects of plutonium-238. Check out this article with some of the health issues of Pu-238: https://t.co/SKRxGZZPSH. #geochemchat

Radiocarbon dating can be used to determine when an earthquake occurred, however inaccuracies can arise. Check out this article on improving the dating of earthquakes through the use of tree rings and radiocarbon dating.

@heisenberg_Wits @_Bubbles0509 Will something as simple as planting more trees make a difference to increase the atmospheric oxygen? #geochemchat

[greyling_wits @greyling_wits]

@Witsgeochem Sulfur isotopes can be used as tracers of atmospheric oxygenation. Sulfur isotopes can be used to determine an increase in atmospheric oxygen which first appeared in the early Paleoproterozoic era #geochemchat

[greyling_wits @greyling_wits]

@Witsgeochem @_Bubbles0509 C13/C12 can be used to study the carbon cycle. The carbon cycle is a very important cycle for life on earth #geochemchat

@Witsgeochem @visagie2089444 Silicate melts are used to study evolution of the earth #geochemchat

[greyling_wits @greyling_wits]

@Witsgeochem @visagie2089444 W is a naturally occurring stable isotope with a strong affinity to metals compared to silicates. The earth’s core is the main reservoir for W on earth. W behaves incompatible during partial melting process in silicate earth thus getting enriched in silicate melts #geochemchat
