|Title:||Interlaboratory Analytical Comparison Study to Support Deepwater Horizon Natural Resource Damage Assessment: Description and Results for Mussel Tissue QA10TIS01|
|Published:||November 02, 2011|
|Abstract:||To support natural resource damage assessment (NRDA) in response to the Deep Water Horizon (DWH) oil spill in the Gulf of Mexico, a large number of coastal sediment and tissue (i.e., oysters) samples have been collected outside of the spill zone to define baseline environmental conditions prior to being exposed to oil. Analysis of oiled sediments and oil-exposed oysters will continue for the foreseeable future. To support these efforts, NOAA will require additional analytical laboratories to support NRDA sample analyses in addition to the commercial laboratories that are currently listed as providing support to NRDA. To compare the data among these laboratories, inter-laboratory comparison studies have been initiated with the results from the third exercise, mussel tissue QA10TIS01 reported here. In this exercise, selected polycyclic aromatic hydrocarbons (PAHs), alkylated PAHs, hopanes, and steranes were determined in the exercise material, which consisted of a cryogenically homogenized mussel tissue sample, and in SRM 1974b Organics in Mussel Tissue (Mytilus edulis). The results from this third exercise are reported along with a summary of the analytical methods used.|
