Latinx child and adolescent farmworkers.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;METHODS: &lt;/strong&gt;Child and adolescent farmworkers aged 13 to 20 years completed questionnaires about menstrual cycle patterns in 2019, and wore silicone passive collection wristbands for pesticide detection in 2018. Menstrual cycle irregularities were determined from the American College of Obstetricians and Gynecologists committee opinion.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;RESULTS: &lt;/strong&gt;Half of participants experienced any menstrual cycle irregularity; the most frequent irregularities were cycle length (38.6%) and having gone 90 days or more without a menstrual period (20.4%). Pesticides were detected in 92.9% of the wristbands; most participants were exposed to an endocrine disrupting chemical (EDC) pesticide.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;CONCLUSION: &lt;/strong&gt;Half of Latinx children and adolescents hired farmworkers experience irregular menstrual cycles, and most are exposed to EDCs. Inclusion of occupational and menstrual histories in child and adolescent medical visits is critical.&lt;/p&gt;

Wristbands and associated methods enabled quantitation of 63 pesticides and screening for 1397 chemicals including environmental contaminants and personal care products. Sixty-eight wristbands were worn for approximately one month by volunteers from four communities of Alto Mayo, Peru. We identified 106 chemicals from eight chemical classes among all wristbands. Agricultural communities were characterized by pesticides and PAHs, while the urban communities had more personal care products present. Multiple linear regressions explained up to 40% of variance in wristbands from chlorpyrifos, cypermethrin, and DDT and its metabolites (DDx) (r(2)=0.39, 0.30, 0.40, respectively). All three pesticides were significantly different between communities, and cypermethrin and DDx were associated with participant age. The calculated relative age of DDT suggested some communities had more recent exposure than others. This work aids health research in the Alto Mayo and beyond by identifying typical mixtures and potential sources of exposure to organic chemicals in the personal environment. Silicone wristband sampling with chemical screening is a candidate for widespread use in exposure monitoring in remote areas.Journal of Exposure Science and Environmental Epidemiology advance online publication, 26 July 2017; doi:10.1038/jes.2017.12.&lt;/p&gt;

With high detection in indoor environments and increasing toxicological evidence suggesting a potential for adverse health effects, there is a growing need for reliable exposure metrics to examine individual exposures to PFRs. Silicone wristbands have been used as passive air samplers for quantifying exposure in the general population and occupational exposure to polycyclic aromatic hydrocarbons. Here we investigated the utility of silicone wristbands in measuring exposure and internal dose of PFRs through measurement of urinary metabolite concentrations. Wristbands were also compared to hand wipes as metrics of exposure. Participants wore wristbands for 5 consecutive days and collected first morning void urine samples on 3 alternating days. Urine samples were pooled across 3 days and analyzed for metabolites of the following PFRs: tris(1,3-dichloroisopropyl) phosphate (TDCIPP), tris(1-chloro-2-isopropyl) phosphate (TCIPP), triphenyl phosphate (TPHP), and monosubstituted isopropylated triaryl phosphate (mono-ITP). All four PFRs and their urinary metabolites were ubiquitously detected. Correlations between TDCIPP and TCIPP and their corresponding urinary metabolites were highly significant on the wristbands (rs = 0.5-0.65, p &amp;lt; 0.001), which suggest that wristbands can serve as strong predictors of cumulative, 5-day exposure and may be an improved metric compared to hand wipes.&lt;/p&gt;

This instrument, with optimized parameters, achieves quantitative separation of 62 polycyclic aromatic hydrocarbons (PAHs). Existing methods historically limited rigorous identification and quantification to a small subset, such as the 16 PAHs the US EPA has defined as priority pollutants. Without the critical source and extractor lens modifications, the off-the-shelf GC-EI/MS/MS system was unsuitable for complex PAH analysis. Separations were enhanced by increased gas flow, a complex GC temperature profile incorporating multiple isothermal periods, specific ramp rates, and a PAH-optimized column. Typical determinations with our refined GC-EI/MS/MS have a large linear range of 1-10,000pgμl(-1) and detection limits of &amp;lt;2pgμl(-1). Included in the 62 PAHs, multiple-reaction-monitoring (MRM) mode enabled GC-EI/MS/MS identification and quantitation of several constituents of the MW 302 PAH isomers. Using calibration standards, values determined were within 5% of true values over many months. Standard curve r(2) values were typically &amp;gt;0.998, exceptional for compounds which are archetypally difficult. With this method benzo[a]fluorene, benzo[b]fluorene, benzo[c]fluorene were fully separated as was benzo[b]fluoranthene, benzo[k]fluoranthene, and benzo[j]fluoranthene. Chrysene and triphenylene, were sufficiently separated to allow accurate quantitation. Mean limits of detection (LODs) across all PAHs were 1.02±0.84pgμl(-1) with indeno[1,2,3-c,d] pyrene having the lowest LOD at 0.26pgμl(-1) and only two analytes above 2.0pgμl(-1); acenaphthalene (2.33pgμl(-1)) and dibenzo[a,e]pyrene (6.44pgμl(-1)).&lt;/p&gt;

The mobile exposure device (MED) is integrated personal environmental exposure tools coupled with software which links health data to location and chemical exposure. The MED combines a wristband passive sampling device with a smart phone application and biometric equipment providing a holistic tool to capture uniquely linked environmental-health information.&amp;nbsp; Silicone passive sampling wristbands sequester organic compounds while a cell phone application captures geographic location of study participants. Users were prompted to test lung function with a spirometer three times daily to identify variation in lung function throughout a typical daily routine.&amp;nbsp; Wristbands were worn daily then mailed to the laboratory, extracted, and analyzed for over 1,200 organic compounds including PAHs, OPAHs, PCBs, pesticides, flame retardants and industrial chemicals. Data is transmitted securely from a laboratory information management system and the smart phone app to a secure server through web services and integrated in order to discover statistical relationships among air pollutants, locations, and lung function. The MED was developed and tested in two different exposure scenarios, one community in Oregon with proximity to intense industrial activity, and another community in Ohio near unconventional natural gas drilling operations. Focus group meetings were employed in both communities to further enhance and optimize the MED. Early beta testing resulted in a daily accumulation of over 600,000 data points including geographic location, lung function, and chemical observations for each participant. The MED coupled with data integration and visualization techniques will enable researchers &amp;nbsp;to gain new insights and investigate new connections, while allowing communities to see their data in more intuitive ways.&lt;/p&gt;
