Iodine was discovered as a novel element in 1811 during the Napoleonic Wars. To
celebrate the bicentennial anniversary of this event we reflect on the history and highlight …

Halogen chemistry is well known for ozone destruction in the stratosphere, however reactive
halogens also play an important role in the chemistry of the troposphere. In the last two …

Brown algae of the Laminariales (kelps) are the strongest accumulators of iodine among
living organisms. They represent a major pump in the global biogeochemical cycle of iodine …

The oceans contribute significantly to the global emissions of a number of atmospherically
important volatile gases, notably those containing sulfur, nitrogen and halogens. Such gases …

Microbial communities associated with produced water from hydraulic fracturing are not well
understood, and their deleterious activity can lead to significant increases in production …

With a projected steady decline of gold ore grade in mineral resources, mining applications
enabling efficient metal extraction from low-grade ores are of increasing interest to the …

129I is commonly either the top or among the top risk drivers, along with 99Tc, at
radiological waste disposal sites and contaminated groundwater sites where nuclear …

Hydraulic fracturing for natural gas extraction from shale produces waste brine known as
flowback that is impounded at the surface prior to reuse and/or disposal. During …

Iodine is an essential trace element for humans and animals because of its important role as
a constituent of thyroid hormones. If the anthropogenic iodine-129 (129I, half-life: 1.6× 107 …

Environmental Context. Atmospheric aerosols play an important role in determining the
earth's radiative budget, climate change and air quality levels. Much effort has been spent …
