... ( Visscher et al., 2004 ). The prime reason for this would be the volcanic activity of the Siberian Traps by release of organohalogens ( Beerling et al., 2007 ). Sporomorphs with darker colors regularly occur in most of the studied samples. Their colors vary from dark brown to black. Opaque black...

... of widespread application of mecoprop, and increasing numbers of other herbicides and pesticides, is now being realized and a number of legislative controls have been introduced. As a List I substance under the Groundwater Directive (80/68/EEC; CEC 1980 ), by virtue of being an organohalogen, its direct...

... (e.g., Wignall, 2015 ). The contemporaneous eruption of the Siberian Traps large igneous province is thought to have been the main trigger of the biological crisis, with the release of vast quantities of volatiles such as CO 2 , SO 2 , organohalogens, and metals to the atmosphere resulting...

... composition of the ocean-atmosphere reservoir ( Payne and Kump, 2007 ), as recorded in beds 24–26. Beerling et al. (2007) further proposed that the release of organohalogens by the Siberian Traps may have severely weakened the ozone layer, to the detriment of plant life. Large tracts of dead vegetation...

... on vegetation may have derived from large-scale degassing of hydrothermal organohalogens (CH 3 Cl, CH 3 Br), contributing to stratospheric ozone depletion and an increased flux of harmful UV radiation in the 290–315 nm (UV-B) range ( Visscher et al., 2004 ). Volcanic emissions may also be responsible...

... in pulses lasting <10 k.y. ( Pavlov et al., 2011 ). In addition to the long-term effects of CO 2 release, these eruptions could have produced severe but geologically short-lived environmental deterioration. We focus on the transient effects of sulfur, halogen, organohalogen, and methane release over...
