This interesting article explains the use of stable water isotopes and the use of N¹⁵ and O¹⁸ isotopes to track nitrates in water to identify sources of ground water contamination. Worth reading! #geochemchat 🧪https://t.co/KZFVqzQt0A

@Senorita4007 @radioac97960451 @greyling_wits @Witsgeochem Growing research of recycling plastics to make useful things like bricks really does give me hope that we may not be going fast enough but we’re moving in the right direction. Like the research project @Rethabile2892 is involved in. @geochemchat

All four of the key DNA building blocks have now been found in meteorites, suggesting that space rocks may have delivered the compounds to Earth, contributing to the origin of life https://t.co/lVz9g0O73L

@Witsgeochem “the cyanobacteria produce the toxin from a bromide-containing herbicide that lake managers use to control the weed.” Classic example of solving a problem by creating an even bigger one.

A recent experiment suggests that iron oxides may be forming far below earth's surface, which could lead to earth's core rusting. #geochemchat

Scientists have hypothesized that radioactive molecules could be used as a tool to explore why there is more matter than antimatter in the universe,by using heavy radioactive molecules they can measure symmetry violations. #geochemchat

The use of Nitrogen-15 and Phosphorus-32 in fertilizer can aid in determining the extent to which the fertilizer is taken in by plants. This is important in minimizing pollution caused by excess fertilizer.
