![]() ![]() string ListMatchesExpr ( string list, string matchExpr, variable exprType ) ¶ Return a list of all objects of the given type from dfr.ĭoes not work for datafolders which have a comma ( ,) in them. List of object names matching matchExpr static string GetAllObjects ( dfref dfr, variable typeFlag ) ¶ Recursive – descent into all subfolders recursivelyĮxprType – convention used for matchExpr, one of MatchExpressions TypeFlag – One of TypeFlagsįullPath – should only the object name or the absolute path of the object be returned MatchExpr – expression matching the objects, either a regular (exprType = MATCH_REGEXP) or wildcard (exprType = MATCH_WILDCARD) expression Parametersĭfr – datafolder reference to search for the objects which honours a dfref and thus does not require SetDataFolder calls. UTF_NOINSTRUMENTATION string GetListOfObjects ( dfref dfr, string matchExpr, variable typeFlag = defaultValue, variable fullPath = defaultValue, variable recursive = defaultValue, variable exprType = defaultValue ) ¶Īlternative implementation for WaveList/VariableList/etc. Var – if zero an error message is printed into the history and procedure execution is aborted, nothing is done otherwise.ĮrrorMsg – error message to output in failure caseĮxtendedOutput – Output additional information on failureĬhecks if the given name exists as window. Unlike ASSERT() this function does not jump into the debugger (Igor Pro limitation). The results demonstrate the need for further investigation into heavy metal speciation and bioavailability in the sediment to ascertain the degree of toxicity.ASSERT_TS(DataFolderExistsDFR(dfr), "dfr does not exist") do something with dfr This provides a more reliable understanding of whole sediment behaviour and classified the ecological risk of the sediment as moderate to very high. Consequently, a modified ecological risk index (MRI) employing enrichment factor is proposed. However, RI could not account for the complex sediment behaviour because it uses a simple contamination factor. Application of potential ecological risk index (RI) revealed that the sediment poses moderate to considerable ecological risk. ![]() A further comparison with the Australian Sediment Quality Guidelines indicated that Ag, Cr, Cu, Ni, Pb and Zn had the potential to rarely cause biological effects while Hg could frequently cause biological effects. Generally, the sediment is deemed to be “slightly” to “heavily” polluted. To overcome inherent deficiencies in using a single index, a range of sediment quality indices, including contamination factor, enrichment factor, index of geo-accumulation, modified degree of contamination, pollution index and modified pollution index were utilised to ascertain the sediment quality. Principal component analysis and cluster analysis identified three main sources of metals in the samples: marine sand intrusion, mixed lithogenic and sand intrusion as well as transport related. Sediment samples were analysed for major and minor elements using LA-ICP-MS. ![]() The distribution, source, contamination and ecological risk status of heavy metals in sediment of Brisbane River, Australia were investigated. Estuarine environment is complex and receives different contaminants from numerous sources that are persistent, bioaccumulative and toxic. ![]()
