Publication year: 2010 Source: Regulatory Toxicology and Pharmacology, In Press, Accepted Manuscript, Available online 10 December 2010 Robin B., DeHate , Giffe T., Johnson , Raymond D., Harbison Soil vapor intrusion (SVI) has recently garnered much interest as a potential exposure route for occupants of properties overlying and surrounding former Manufactured Gas Plants (MGPs). This investigation evaluates SVI at 10 commercial buildings and 26 single family and multi-family residential properties overlying and/or adjacent to three former MGPs. SVI was evaluated in three categories according to thickness of the vadose zones: no vadose zone; 0 – 6 feet thick, and 6 to 25 feet thick.

Publication year: 2010 Source: Palaeogeography, Palaeoclimatology, Palaeoecology, In Press, Accepted Manuscript, Available online 10 December 2010 A., Zazzo , J.-F., Saliège Since the early trials in the 50′s, the reliability of 14C dates obtained from bioapatites has always been questioned. However, methodological attempts at dating biological apatites are rare. The compilation of the radiocarbon dates published in Radiocarbon over the period 1959-2009 shows that less than 6% of all the bone dates were performed on purified bioapatite

Evaluation of more than 7,400 skeletonized benthic invertebrates and taphonomic processes reveal a general pattern of increasing diversity and abundances of skeletozoans through the Early Triassic in tropical marine environments on the coast of western Pangea (present-day western U.S.A.). Griesbachian age skeletobiont assemblages are dominated by episkeletozoans, while Spathian ones are dominated by endoskeletozoans.
