Environmental Chemistry is now on Twitter straight from CSIRO Publishing 🎉Keep up with us for the best #Chemistry research! Let’s dive into all things #EnvironmentalScience ! #EnviroChem

A message from Environmental Chemistry Publisher - CSIRO Publishing "As a publisher within a research organisation, supporting the scientific community is crucial to us. Our collaboration with Research4Life is one way we ensure access for those in lower income countries." #OpenAccess

Can inorganic arsenic (Asi) and dimethylarsenic (DMA) impact the growth of hydroponically grown Doongara rice? Absolutely! Although plants can uptake Asi faster, DMA translocates at a higher rate, indicating greater effects on plant health. Read more: publish.csiro.au/EN/EN23114

Mineral dust is an important source of essential and potentially toxic trace metals for the ocean’s organisms! Stockdale & Krom explore how anthropogenic acidic atmospheric gases impact the bioavailability of Al, Co, Pb and more in desert dust. Read more: doi.org/10.1071/EN23117

Our study intercomparing results from proteomics labs on ocean samples is out. Consistency across labs and lessons were learned are shared. These are necessary efforts for comparing ocean diagnostic data across time and space. Thanks to the study contributors.Biogeoscapes

Could ecological risk of pesticides be assessed without vertebrate testing? This paper explores different approaches using alternative lines of evidence for fish, birds and mammals. Read more: publish.csiro.au/EN/EN23105

Increasing wildfire activity, driven by climate change, underpins the need to characterize smoke emissions, with potential to impact human health. Jaoui & Co. show significant changes to smoke composition, (i.e., PM2.5) linked to fuel moisture. Read more: doi.org/10.1071/EN23013

Is bioavailable Arsenic hiding in your mushrooms? Walenta & Co. determined As speciation, an important indicator of toxicity, in commonly consumed mushrooms. Read more about their work (spoiler: health risks are unlikely if <2kg are eaten!):  doi.org/10.1071/EN22069

The use of crumb rubber from recycled tires results in unintended microplastic pollution. Cunningham et al investigate the relationship between plastic size and toxicity effects in D. magna, finding that chronic exposure has severe reproductive effects. Read more: 10.1071/EN23131

Mercury (Hg) contamination is a global health concern. Cardenas & company found that Hg is present at high concentrations, even in pristine lakes in the Andes. They report seasonal changes in Hg behavior, with impacts on biotic uptake! The full story: doi.org/10.1071/EN24088
