Formation, photochemistry and fate of gas-phase peroxyl radicals. This project aims to understand how peroxyl radical reactions modulate the composition of air. The gas-phase chemical reactions of organic peroxyl radicals contribute to air quality in clean and polluted environments. However, experimental observations of these reaction intermediates and the complex mechanisms governing their formation and fate are limited. This project will use mass spectrometry and laser-based methods to interro ....Formation, photochemistry and fate of gas-phase peroxyl radicals. This project aims to understand how peroxyl radical reactions modulate the composition of air. The gas-phase chemical reactions of organic peroxyl radicals contribute to air quality in clean and polluted environments. However, experimental observations of these reaction intermediates and the complex mechanisms governing their formation and fate are limited. This project will use mass spectrometry and laser-based methods to interrogate the chemical and photochemical reactions of peroxyl radicals in the gas phase. This project expects to understand the composition and dynamics of the troposphere and inform strategies to improve air quality.Read moreRead less
Darwin Harbour corals as environmental data archives and bio-monitors. The forecast rapid population growth and industrial development of the Darwin Harbour catchment necessitates research into novel environmental monitoring techniques to aid the sustainable management of the Harbours resources. This project will develop a powerful and cost-effective bio-monitoring system by using chemical data stored in yearly growth bands of coral skeletons stretching back at least two centuries. Such data wil ....Darwin Harbour corals as environmental data archives and bio-monitors. The forecast rapid population growth and industrial development of the Darwin Harbour catchment necessitates research into novel environmental monitoring techniques to aid the sustainable management of the Harbours resources. This project will develop a powerful and cost-effective bio-monitoring system by using chemical data stored in yearly growth bands of coral skeletons stretching back at least two centuries. Such data will form a comparative baseline against which present and future coral data on pollutants released by urban, industrial and other developments can be assessed.Read moreRead less
A global platform for identifying emerging chemical threats. This project aims to develop an automated early warning social network to systematically detect newly identified emerging chemical threats. Rapid identification of chemical exposures is key to managing chemical threats and associated risks. Global collaboration and sharing of archived, high-resolution mass spectrometry data through open/social platforms will revolutionise data processing and chemical threat identification. This project ....A global platform for identifying emerging chemical threats. This project aims to develop an automated early warning social network to systematically detect newly identified emerging chemical threats. Rapid identification of chemical exposures is key to managing chemical threats and associated risks. Global collaboration and sharing of archived, high-resolution mass spectrometry data through open/social platforms will revolutionise data processing and chemical threat identification. This project will result in a new and cost-effective approach for the identification, tracking and prioritisation of emerging chemical threats and address key national and global health risks. The outcomes include the first spatial and temporal distribution of new emerging chemical threats in Australia.Read moreRead less
Uncovering Antarctica’s Secret Chemical Voyagers for Expedited Regulation. This project aims to strengthen global chemical policy by rapidly identifying chemicals that demonstrate environmental persistence and mobility, two requisite risk criteria for regulatory action. It will take the novel approach of applying powerful non-target chemical screening approaches to Antarctic environmental media, leveraging the remoteness of Antarctica to derive unambiguous evidence against the key risk criteria. ....Uncovering Antarctica’s Secret Chemical Voyagers for Expedited Regulation. This project aims to strengthen global chemical policy by rapidly identifying chemicals that demonstrate environmental persistence and mobility, two requisite risk criteria for regulatory action. It will take the novel approach of applying powerful non-target chemical screening approaches to Antarctic environmental media, leveraging the remoteness of Antarctica to derive unambiguous evidence against the key risk criteria. Research will uncover a new catalogue of proven persistent and mobile chemicals, and further assess their ubiquity and biomagnification potential in the Antarctic system. Project findings will be directly disseminated to policymakers, facilitating expedited regulatory decision-making for improved Planetary Health outcomes.Read moreRead less
