This dataset includes pesticides and pesticide transformation products in 15 tributaries of the Great Lakes. Pesticides were monitored using polar organic chemical integrative samplers (POCIS) to estimate concentrations in water following standard protocols (Alvarez, 2010) in June and July 2016. POCIS extracts were analyzed for 225 chemicals (USGS National Water Quality Laboratory schedule 5437, Sandstrom and others, 2016), for which 129 chemicals also have POCIS uptake rates, allowing calculations of time-weighted mean concentration over the approximately 30 day deployment (Alvarez and others, 2008). Collectively, there were 97 chemicals detected, and time-weighted mean concentrations could be calculated for 95...

This is a collection of data on the contamination of water, fish, and sediments in Biscayne National Park and in canals that discharge into the national park. The water data are estimations of their concentrations in water based on sampling with passive water samplers (semi-permeable membrane devices and polar organic chemical integrative samplers). Also in this data set are estrogen equivalencies for the chemical mixtures in the polar organic chemical integrative samplers.

Background Industrial discharges of toxic and bio-accumulating compounds to the Niagara River and its tributaries have occurred over many decades. High concentrations of polychlorinated biphenyls (PCBs) have been found in samples of fish tissue from many locations, including three tributaries to the Niagara River: Tonawanda Creek, Two mile Creek, and Rattlesnake Creek (study reaches listed in Table 1). Study site for SPMD sampler in a tributary to the Niagara River High PCB concentrations have also been found in mussel tissues during in situ experiments in the latter two creeks PCBs have been detected in sediments from many locations, but they were generally lower than expected given the elevated PCB concentrations...

Water-borne polychlorinated biphenyls (PCBs) were sampled in three tributaries of the Niagara River Area of Concern (AOC) in 2018 and 2019 using semipermeable membrane devices (SPMDs). This data set is a compilation of data from two sampling efforts, focused on determining the presence and distribution of total and congener PCBs in these tributaries.

This dataset includes per-and polyfluoroalkyl substances (PFAS) and pharmaceuticals monitored at 62 sampling sites in tributaries of the Laurentian Great Lakes. Chemicals were evaluated in a sediment sample (PFAS only) and water concentrations were estimated using polar organic chemical integrative samplers (POCIS). Sediment samples were collected from the 62 sites in June and July 2018, which were analyzed for 23 PFAS compounds using liquid chromatography tandem mass spectrometry (LC/MS/MS). Duplicate sediment samples were collected at 23 sites. Overall, 22 of the 23 sediment PFAS compounds analyzed were detected in samples from at least one site. Pharmaceuticals and PFAS samples were collected instream by deploying...
