- Title:
- Fish Contaminant Monitoring Sampling Sites and Select Results (Consolidated Version) [Michigan]
- Description:
- Note that this layer contains the same information astheMichigan Fish Contaminant Monitoring Program Sampling Sites and Select Results. They are distinct in structure only (the data is the same). Thisis a single flattened file, while the other is a layer with a related table containing results.These data are a static pull of the Michigan Department of Environment, Great Lakes, and Energy'sFish Contaminant Monitoring Program(EGLE-FCMP) on 11/01/2023. Each year EGLE-FCMP collects fish from all over the state for contaminant testing. The majority of these fish are used to inform theMichigan Department of Health and Human Services' Eat Safe Fish Program(MDHHS-ESF) fish consumption advisories. In these instances, the edible portion (e.g. fillets, headless and gutted rainbow smelt, lake sturgeon steaks) is removed from the fish and sent to theMDHHS Bureau of Laboratories(MDHHS-BOL) for contaminant testing. Only edible portion data are shown with select contaminants used by the MDHHS-ESF for advisory development. This layer will be updated annually. Additional data (e.g. whole fish) that are not used to inform the MDHHS-ESF advisories are available upon request.Prior to 2000, polychlorinated biphenyls (PCBs) were analyzed using an Aroclor method. Afterwards, a congener method was used to analyze PCBs. Total PCB concentration was estimated by summing the concentrations of the PCB congeners (or Aroclors) listed in the latest FCMP report found athttps://www.michigan.gov/FCMP. Total dichlorodiphenyl trichloroethane (DDT) was calculated by summing concentrations of the para, para' and ortho, para' forms of the following chemicals: DDT, dichlorodiphenyl dichloroethane (DDE), and 1,1 bis(4-chlorophenyl)-2,2-dichloroethane (DDD). Total chlordane was estimated by summing the concentrations of five chlordane breakdown products: alpha-chlordane, gamma-chlordane, cis-nonachlor, trans-nonachlor, and oxychlordane. Finally, total 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) toxic equivalents (TEQ) were calculated using the USEPA recommended toxic equivalency factors for seven dioxin, 10 dibenzofuran, and 12 dioxin-like PCB (dl-PCB) congeners (USEPA, 2010). The concentrations of individual dioxin, dibenzofuran, and dioxin-like PCB congeners in a fish sample were multiplied by toxic equivalency factors; the resulting products were summed to calculate a 2,3,7,8-TCDD TEQ concentration. Prior to 2008, TEQs were calculated using only the 17 dioxin and dibenzofuran congeners. These earlier data were excluded from this data set. The standard analytical method for toxaphene can identify a residue with chromatographic characteristics similar to toxaphene but does not specifically identify the residue as the pesticide toxaphene. Those results are referred to as "apparent toxaphene." In 2009, MDHHS developed an analytical method (Parlar Method) that provides precise measurements of the concentrations of several toxaphene congeners (Parlars 26, 40, 41, 44, 50, and 62) as well as the toxaphene degradation products commonly referred to as hexachlorobornane (Hx-Sed) and heptachlorobornane (Hp-Sed). Due to the higher cost of this analytical method it is used selectively on sample sets with relatively high apparent toxaphene concentrations.Contaminant data often include flags, also known as qualifiers or codes, which are notes attached to data that gives detailed information about that particular result. In the fish contaminant data layer, a "K" indicates that particular chemical was not detected in the sample and therefore the method detection limit (MDL) is displayed. "J" flagged results indicate an estimated concentration. "J" flags can occur for a variety of reasons including the concentration being outside of the laboratory's standard curve for that chemical. "I" flag indicates that analytical interference was present in the sample; therefore, a concentration could not be determined. Finally, "QNS" indicates that there was not enough sample remaining from the other contaminant analyses to analyze the sample for this chemical.Questions regarding these data can be directed toEGLE's FCMP. MDHHS-ESF is currently reviewing some newer data in this database for updates to Eat Safe Fish guidelines. Please refer to the Eat Safe Fish Guides for current fish consumption guidelines issued by MDHHS. Questions related to consumption advisories based on these data can be directed toMDHHS-ESF.If you are interested in having your water body tested for fish contaminants, please consider submitting aTargeted Monitoring Request.FieldDescriptionUSGSHUCUnited States Geological Survey Hydrological Unit CodeCountyNameCounty NameStationIDSampling Station Identification NumberWaterBodyWater BodySamplingLocationSampling LocationLatLatitudeLongLongitudeCollectionDateCollection DateSpeciesSpecies of FishSexSex of FishAgeAge of Fish in yearsLengthcmLength of Fish in centimetersWeightgWeight of Fish in gramsSampleTypeSample TypeVisitIDVisit Identification NumberSampleIDSample Identification NumberFishIDFish Identification NumberMercuryppmMercury concentration in parts per millionMercuryCodeLaboratory code or flag for mercury concentrationPerfluorooctaneSulfonateppbPFOS concentration in parts per billionPFOSCodeLaboratory code or flag for PFOS concentrationTotalChlordaneppmTotal Chlordane concentration in parts per millionChlordaneCodeLaboratory code or flag for Chlordane concentrationTotalDDTppmTotal DDT concentration in parts per millionDDTCodeLaboratory code or flag for DDT concentrationTotalPCBAroclorppmTotal PCB (Aroclor method) in parts per millionPCBAroclorCodeLaboratory code or flag for PCB aroclor concentrationTotalPCBCongenersppmTotal PCB (Congener method) in parts per millionPCBCongenerCodeLaboratory code or flag for PCB congener concentrationToxapheneppmToxaphene concentration in parts per millionToxapheneCodeLaboratory code or flag for Toxaphene concentrationTEQpptTotal TCDD toxic equivalents (TEQ) concentration in parts per trillion
