Dataset includes the analysis results of 49 inorganic chemical elements bound to suspended-sediment particles below Paonia Reservoir during a sediment release in September 2017. Suspended-sediment samples were collected at U.S. Geological Survey (USGS) station number 385626107212000 by following data collection procedures and protocols in Edwards and Glysson (1999). The samples were freeze-dried after collection and then decomposed using a mixture of nitric, hydrofluoric, and perchloric acids. The dried residue after acid digestion was analyzed by atomic absorption spectrometry and inductively coupled plasma-mass spectrometry following procedures and protocols in Taggart (2002). Reference samples of flue gas desulfurization...

The U.S. Geological Survey (USGS) collected porewater samples from nine suction lysimeters in 2018, 2019, and 2021 for analysis of organic and inorganic constituents from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, MN. In August of 1979, approximately 1,700,000 L (liters), or 10,700 barrels, of crude oil spilled onto a glacial outwash aquifer. Sampled lysimeters included L310-1.5, L310-4.5, L1802-1.8, L9014-1.5, L9014-3.0, L9014-4.5, L9017-1.3, L9017-2.5, and L9017-3.7. This data release presents data on analytes that are important indicators of biodegradation processes. Some of these analytes, if present in elevated concentrations, can be a concern regarding potential effects...

Illegal logging is one of the leading causes of deforestation today. Sadly, tree species indigenous to regions critical to maintaining Earth’s ecological diversity also possess properties (i.e. appearance, aroma, etc.) desirable to humans, which often leads to exploitation. In 1992, due to illegal logging, Brazilian rosewood (Dalbergia nigra) became the first ever tree species to be listed in an appendix of the Convention of International Trade in Endangered Species of Wild Fauna and Flora (CITES), which prohibited international trade of the timber or other products from this species between entities which had voluntarily joined CITES. Despite its inclusion in Appendix I of CITES, the species continues to be logged...

The titanium concentrations were obtained from a data set that is called the "National Geochemical Survey." This data set, as well as its documentation, are available in U.S. Geological Survey Open-File Report 2004-1001 (https://mrdata.usgs.gov/geochem/doc/home.htm). The titanium concentrations were measured in 3,457 samples of stream sediments from the coastal plain of the southeastern United States; this area includes parts of Virginia, North Carolina, South Carolina, Georgia, Florida, and Alabama. The samples were collected between 1975 and 1999 during several field surveys, and the concentrations were measured using inductively coupled plasma-atomic emission spectrometry.
