#unsw — Public Fediverse posts

Paper publication day is one of my favourite days! Our paper on wildfire ash chemistry is out today and #OpenAccess in the #AGU journal 'Geochemistry, Geophysics, Geosystems.' We analysed the inorganic and organic chemistry of wildfire (and prescribed burn) ashes from 4 karst areas in Australia and found that ash chemistry varies with burn severity and sampling location. Another team effort from #ANSTO, #UNSW, #UWA, #GNSScience colleagues (👋 @Andbaker )

If you are interested in the chemical tracers of wildfires, and how those might vary with burn severity, check out our new #preprint https://www.authorea.com/doi/full/10.22541/au.170689252.26414470/v1

We leached wildfire ashes and soils from karst areas, so we can better understand the speleothem palaeofire proxy signal. Another team effort, with co-authors from #UNSW (👋 @Andbaker) #ANSTO, #UWA, and #GNSScience

A photo from today's UNSW Earth and Environmental Sciences class. 100+ students brought in 100+ soil samples for analysis for lead concentration. Thanks to the speed and ease of use of portable x-ray fluorescence analysers, 100+ samples is no problem.

Next week the students will develop hypotheses and start to analyse the data, before writing a report on Sydney soil lead concentrations.

Historically, lead in city soil comes from traffic pollution, lead paint and lead solder, and this persists in the environment today.

Some samples had high lead concentrations, we will retest those and offer advice.
