“…Perylene‐d12 was used as the instrumental internal standard. Transport stability studies performed by Donald et al verified that the transport times (12 h) and temperatures (<20 °C) should not result in loss of PAHs. All solvents used were Optima grade or better (Fisher Scientific), and standards were purchased at purities ≥97%.…”

Superfund sites may be a source of polycyclic aromatic hydrocarbons (PAHs) to the surrounding environment. These sites can also act as PAH sinks from present day anthropogenic activities especially in urban locations. Understanding PAH transport across environmental compartments helps to define the relative contributions of these sources and is therefore important for informing remedial and management decisions. In the present study, paired passive samplers were co-deployed at sediment-water, and water-air interfaces within the Portland Harbor Superfund site (PHSS) and the McCormick and Baxter Superfund Site (MCBSS). These sites, located along the Willamette River in Portland, Oregon, have PAH contamination from both legacy and modern sources. Diffusive flux calculations indicate that the Willamette River acts predominately as a sink for low molecular weight PAHs from both the sediment and the air. The sediment was also predominately a source of 4 and 5 ring PAHs to the river and the river was a source of these same PAHs to the air, indicating that legacy pollution may be contributing to PAH exposure for residents of the Portland urban center. At the remediated MCBSS flux measurements highlight locations within the sand and rock sediment cap where contaminant breakthrough is occurring.

“…Wristbands were purchased from 24HourWristbands. Conditioning, postdeployment cleaning, and extraction of the wristbands were performed as described previously 69–71 . Briefly, wristbands were rinsed in deionized water to remove particulates, 68 dried, and conditioned in a Blue‐M Model# POM‐18VC‐2 vacuum‐oven (300°C, 0.12 Torr) for 3 h with periodic N 2 sweeps.…”

“…Extraction surrogates tetrachloro‐meta‐xylene, decachlorobiphenyl, and PCB100 were added and the wristbands extracted with two 50 ml volumes of ethyl acetate, combined and quantitatively reduced to 1 ml. When necessary to remove analytical interferences, a 200 μl aliquot of extract underwent solid‐phase extraction on a C18 silica column with acetonitrile, 71,72 followed by a solvent exchange to isooctane for injection. All solvents were Optima‐grade or equivalent (Thermo Fisher Scientific).…”

Background Although pesticides have adverse effects on child health and development, little research has examined pesticide exposure among child farmworkers. This analysis addresses two specific aims: (1) describes pesticide exposure among Latinx child farmworkers in North Carolina, and (2) delineates factors associated with this pesticide exposure. Methods In 2018 (n = 173) and 2019 (n = 156) Latinx child farmworkers completed interviews and wore silicone wristbands for a single day to measure pesticide exposure. Wristbands were analyzed for 70 pesticides. Results Most Latinx child farmworkers were exposed to multiple pesticides; the most frequent were pyrethroids (69.9% in 2018, 67.9% in 2019), organochlorines (51.4% in 2018, 55.1% in 2019), and organophosphates (51.4% in 2018, 34.0% in 2019). Children were exposed to a mean of 2.15 pesticide classes in 2018 and 1.91 in 2019, and to a mean of 4.06 pesticides in 2018 and 3.34 in 2019. Younger children (≤15 years) had more detections than older children; children not currently engaged in farm work had more detections than children currently engaged in farm work. Migrant child farmworkers had more detections than nonmigrants. For specific pesticides with at least 20 detections, detections and concentrations were generally greater among children not currently engaged in farm work than children currently engaged. Conclusions Children who live in farmworker communities are exposed to a plethora of pesticides. Although further research is needed to document the extent of pesticide exposure and its health consequences, sufficient information is available to inform the policy needed to eliminate this pesticide exposure in agricultural communities.

“…As there is no need for electricity supply, they can be used in remote areas (reviewed by Domínguez-Morueco et al 2017). Some guidelines, however, require that fielddeployed passive samplers should be preserved and transported frozen or near frozen as soon as possible which is not always feasible (Donald et al 2016). Other drawback is the sensitivity to environmental, mostly meteorological conditions (Marć et al 2015).…”

Biomonitors are considered a cheap alternative of active air samplers, especially where spatial pattern of air quality is to be monitored, requiring numerous parallel measurements. Of higher plants, Plantago lanceolata L. has been proven a good monitor species with proper accumulation capacity. While biomonitoring studies are difficult to compare due to inherent errors such as the diverse plant material used in different studies, the No. 227 OECD GUIDELINE FOR THE TESTING OF CHEMICALS: Terrestrial Plant Test: Vegetative Vigour Test provides a tool to test extract of aerosol samples under controlled laboratory conditions. In our study, this guideline was followed to experimentally treat Plantago with the aqueous extract of a diesel exhaust sample. Accumulation pattern of polyaromatic hydrocarbons (PAHs) was assessed and compared to samples collected in the field. Unlike most studies reported in the literature, both in the experimentally treated and field Plantago samples, high ratio of high molecular weight PAHs was experienced. Distribution pattern of accumulated PAHs showed strong correlation between the experimentally treated sample and most of the field plantain samples, underlying the usefulness of laboratory treatments for bioaccumulation studies.
