GEUS Geochemistry

News from the Danish pesticide leaching assessment program (PLAP) – the new PLAP-report focusing on the pesticide monitoring results from 2018 to 2020 is available. Read it on: pesticidvarsling.dk/wp-content/upl…

2/2. ...and not only, as previously described, inflow induced by excess groundwater abstraction. @AquaEtMontibus @EddyEdgeconnect @FlemmingGEUS #research #publication #contamination #groundwater #arsenic sciencedirect.com/science/articl…

1/2. A new one out: @GEUS_Geochemist+others found that high groundwater arsenic levels in Pleistocene aquifers of the Red River delta are the result of a limited extent of flushing and inflow of arsenic-contaminated groundwater from Holocene aquifers along natural flow paths...

2/2. This trip involved meetings with several Indian water-related experts and field visits. We'll keep you posted as we progress!

1/2. A team from @GEUS_Geochemist and @hydrologygeus is back from a great trip to India. The trip is part of the Strategic Sector Cooperation (SSC) between the Ministry of Jal Shakti, Government of India and the Environmental Protection Agency, Ministry of Environment of Denmark.

A team of @GEUS_Geochemist described the relation between groundwater arsenic content and sedimentary environment derived from remote sensing. It enables mapping low arsenic groundwater in rural areas. sciencedirect.com/science/articl…

In the Geochemistry Department, we are happy to get our hands full this year contributing with exciting experiments and numerical modeling in these projects: eudp.dk/nyheder/eudp-s… geus.dk/om-geus/nyhede…

Work involving @GEUS_Geochemist show that aquatic eutrophication is linked to 4.5 ka of human activity and reached a historical maximum after Medieval deforestation. Hence, preindustrial conditions cannot be used as pristine for eutrophication. sciencedirect.com/science/articl…

My newest paper on #preferential transport of #ARGs of agricultural land, and contamination of the #aquatic environment. #OneHealth @GEUS_Geochemist pubs.acs.org/doi/abs/10.102…

First international meeting in Bruxelles ✈ with #HOVER #GeoERA revealing a great but highly variable degradation potential for pesticides and antibiotics at the groundwater-surface water interaction zones 🌍 #OneWater

(3/3) @GEUS_Geochemist on the leaching risk and fate of pesticides from coated seeds. Coated seeds with triazole fungicides were studied to assess the fate of the fungicides and their degradation products especially 1,2,4-triazole: doi.org/10.1016/j.chem… @norasbadawi

(2/3) #GEUS and others investigated the effects on reservoir quality for aquifer thermal energy storage. Specifically, the chemical effects of heating the Bunter Sandstone Formation were investigated: doi.org/10.1016/j.geot…

(1/3) Some more interesting work involving #GEUS @GEUS_Geochemist published during the summer:

(4/4) By combining field studies and numerical modeling, #GEUS and others evaluated the impact of fate properties in the topsoil of golf courses with and without preferential flow using different bottom boundary conditions: doi.org/10.1016/j.envp… @SachinKaran_1 @norasbadawi

(3/4) #GEUS involving @GEUS_Geochemist, @hydrologygeus, and others studied catchment disturbances from early land use to Lake Væng. Their results indicated a lengthy and varying history of aquatic eutrophication linked to human activity: doi.org/10.1016/j.ance…
