Environmental forensic evidence from perchlorate in dust fall [PDF]

open access: yes, 2016
Summer in Malta is accompanied by fireworks as part of the numerous (about 85) religious festivals (festa) that occur throughout the period. We attempted to establish whether firework activity is truly following official trade statistics, which imply a ...

Stratospheric Gas‐Phase Production Alone Cannot Explain Observations of Atmospheric Perchlorate on Earth

open access: yesGeophysical Research Letters, 2023
Perchlorate has been observed in many environments on Earth and Mars but its sources remain poorly quantified. In this study, we use a global three‐dimensional chemical transport model to simulate perchlorate's gas‐phase photochemical production ...

Hypotheses for near-surface exchange of methane on Mars [PDF]

open access: yes, 2016
The Curiosity rover recently detected a background of 0.7 ppb and spikes of 7 ppb of methane on Mars. This in situ measurement reorients our understanding of the Martian environment and its potential for life, as the current theories do not entail any ...

Bond length of perchlorate at different temperatures: X-ray and neutron comparison. [PDF]

open access: yes, 2020
The averages (average deviations from the mean are given in square brackets) of uncorrected Cl-O bond distances in a perchlorate anion from an X-ray diffraction analysis of (N-{2-[bis(pyridin-2-ylmethyl)amino]ethyl}pyridine-2-carboxamidato)(nitric oxide ...

Resistance and Resilience of Sulfidogenic Communities in the Face of the Specific Inhibitor Perchlorate

open access: yesFrontiers in Microbiology, 2019
Hydrogen sulfide is a toxic and corrosive gas, produced by the activity of sulfate-reducing microorganisms (SRM). Owing to the environmental, economic and human-health consequences of sulfide, there is interest in developing specific inhibitors of SRM ...

Perchlorate Exposure Reduces Primordial Germ Cell Number in Female Threespine Stickleback. [PDF]

open access: yesPLoS ONE, 2016
Perchlorate is a common aquatic contaminant that has long been known to affect thyroid function in vertebrates, including humans. More recently perchlorate has been shown to affect primordial sexual differentiation in the aquatic model fishes zebrafish ...

Benchmark Calculations for Perchlorate from Three Human Cohorts [PDF]

open access: yes, 2005
The presence of low concentrations of perchlorate in some drinking water sources has led to concern regarding potential effects on the thyroid. In a recently published report, the National Academy of Sciences indicated that the perchlorate dose required ...

Functional Redundancy in Perchlorate and Nitrate Electron Transport Chains and Rewiring Respiratory Pathways to Alter Terminal Electron Acceptor Preference

open access: yesFrontiers in Microbiology, 2018
Most dissimilatory perchlorate reducing bacteria (DPRB) are also capable of respiratory nitrate reduction, and preferentially utilize nitrate over perchlorate as a terminal electron acceptor.

Transport and degradation of perchlorate in deep vadose zone: implications from direct observations during bioremediation treatment [PDF]

open access: yesHydrology and Earth System Sciences, 2017
An in situ bioremediation experiment of a deep vadose zone ( ∼  40 m) contaminated with a high concentration of perchlorate (> 25 000 mg L−1) was conducted through a full-scale field operation.
