Relative percent contributions of microcystin congeners are also provided for samples analyzed by LC-MS and LC-MS/MS.\nSolid phase adsorption toxin tracking (SPATT) and diffusive gradients in thin-films (DGT) are types of passive environmental samplers containing porous synthetic resin beads that adsorb and concentrate cyanotoxins over time. SPATT and DGT samplers are relatively inexpensive to construct and have been widely demonstrated to adsorb a range of cyanotoxins in different environments. These samplers can be deployed in water bodies for time periods ranging from hours to weeks and, upon extraction and analysis, provide a semi-quantitative, relative dissolved cyanotoxin concentration that is calculated based on the deployment length.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.6577157bd34e952b22746005.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9OZR89E", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6577157bd34e952b22746005", "keyword": ["biota", "hazards", "inlandWaters", "United States", "enzyme-linked immunosorbent assay (ELISA)", "cyanotoxin", "USGS:6577157bd34e952b22746005", "Seneca Lake Platform (Site ID: 425027076564401)", "cyanobacteria", "surface water quality", "limnology", "Skaneateles Lake", "saxitoxin", "ecotoxicology", "solid phase adsorption toxin tracking (SPATT)", "cylindrospermopsin", "phytoplankton", "mass spectrometry", "anatoxin", "diffusive gradients in thin-films (DGT)", "fresh water (surface)", "environment", "congener", "Owasco Lake", "algae", "Owasco Lake Platform (Site ID: 425327076313601)", "water resources", "Skaneateles Lake Platform (Site ID: 425606076251601)", "Finger Lakes", "environmental proxies", "water quality", "Seneca Lake", "New York", "algal blooms", "microcystin", "lake ecosystems"], "modified": "2025-06-02T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-77.0389, 42.3565, -76.2286, 42.9682", "theme": ["geospatial"], "title": "Cyanotoxin Concentrations in Extracts from Solid Phase Adsorption Toxin Tracking (SPATT) and Diffusive Gradients in Thin-Films (DGT) Samplers in Owasco Lake, Seneca Lake, and Skaneateles Lake, Finger Lakes Region, New York, 2019"}
