“…In contrast, dicofol displayed a widespread distribution in gas phase in samples collected from the Bohai Sea in August 2016 (89%), and was also detected in 44% of the samples in December 2016. The presence of pollutants in the particulate phase depends on the physicochemical properties of each compound (Carratala et al, 2017); the lower detection rate might be attributed to the higher logK oa value of dicofol (Table S4).…”

“…Seasonal variations of most types of CUPs in the atmosphere are related to their usage, with the highest concentrations measured in the spring or summer (Carratala et al, 2017;Estellano et al, 2015;Yao et al, 2008a;Zhong et al, 2012b). However, little is known about their seasonal distribution in the marine environment, especially in the highly human impacted Bohai Sea.…”

“…Riverine inputs could be important sources not only for CUPs with relatively high water solubility, but also for CUPs with low water solubility (Zhong et al, 2014). CUPs can be transported by currents into the offshore and deep ocean regions, and hence threaten coastal and pelagic ecosystems (Carratala et al, 2017;Li et al, 2015;Mai et al, 2013). Airwater exchange is also an important process that transports CUPs.…”

“…They are now among the catalog of 'emerging pollutants' (Mai et al, 2013). CUPs are not only identified in the regions where they are applied, such as agricultural and forestry areas (Arinaitwe et al, 2016;Asman et al, 2005;Feng et al, 2016;Yao et al, 2008a), rural and urban areas (Carratala et al, 2017;Coscolla et al, 2017;Estellano et al, 2015), but also in regions far away from their sources, such as the Arctic (Hoferkamp et al, 2010;Morris et al, 2016;Walker and Nidiry, 2002;Zhong et al, 2012a), high mountains (Hageman et al, 2006), the and Indian-Pacific Ocean (Bigot et al, 2016). China produces and consumes the largest amount of CUPs in the world.…”

“…Outdoor herbicide concentrations were greater in winter, while insecticide concentrations were greater in autumn; no differences between rural and urban air concentrations was observed. [76,77] A Scandinavian study found that while personal homeowner exposure was poorly associated with application of 2,4-D, 68% of exposure variation in occupational application of 2,4-D was explained by nozzle type and personal protective equipment (PPE) used. [78] Much of the community exposure data available evaluates home exposures near agricultural areas.…”

set. Without her seeking help for data entry, this thesis would not have evolved into what it has. In addition, thank you to Diane Rohlman and Nate Fethke, for their commitment and guidance as committee members. This thesis would not have been possible without the training grant received from the Centers for Disease Control and Prevention and the National Institute for Occupational Safety and Health. The Great Plains Center for Agricultural Health also provided necessary support for this research. Last, but certainly not least, thank you to the University of Iowa and the faculty of the Occupational and Environmental Health program. Without their belief in me, I would not have a position at one of the best universities in the country. Moreover, I would not have been able to make the lasting connections that I have. Thank you.

BACKGROUDPesticides are widely used to control insect infestation and weeds in agriculture. However, concerns about the pesticide residues in agricultural products have been raised in recent years because of public interest in health and food quality and safety. Thus, rapid, convenient, and accurate analytical methods for the detection and quantification of pesticides are urgently required.RESULTSA nanohybrid system composed of gold nanoparticles (AuNPs) and tetrakis(N‐methyl‐4‐pyridiniumyl) porphyrin (TMPyP) was used as an optical probe for the detection and quantification of five pesticides (Paraquat, Dipterex, Dursban, methyl thiophanate and Cartap). The method is based on the aggregation effect of pesticides on the carboxyl group modified by AuNPs. Subsequently, with the help of particle swarm optimization‐optimized sample weighted least squares‐support vector machine (PSO‐OSWLS‐SVM), all the pesticides could be successfully quantified. In addition, partial least squares discriminant analysis (PLS‐DA) was applied and the five pesticides were satisfactorily recognized based on data array obtained from the ultraviolet visible (UV‐visible) spectra of AuNP–TMPyP complex. Furthermore, the quantitative and qualitative analysis of the five pesticides could be also achieved in the complex real samples, in which all the relative standard deviations (RSDs) were less than 0.3‰ and all the linear absolute correlation coefficients were more than 0.9990. Furthermore, recognition rate of the training set and the prediction set based on multiplicative scatter correction (MSC), or second‐order derivative (2nd derivative) UV‐visible spectra in PLS‐DA model could reach 100%.CONCLUSIONThis method was successfully applied for the rapid and accurate determination of multicomponent pesticide residues in real food samples. © 2020 Society of Chemical Industry
