Plasticizers are plastic additives used to enhance the physical properties of plastic and are ubiquitous in the environment. A class of plasticizer compounds called phthalate esters that are not fully eliminated in wastewater treatment facilities are relevant to the ecological health of downstream ecosystems and urban areas due to their ecotoxicity, tendency for soil accumulation, and the emerging concern about their effects on public health. However, plasticizer concentrations in a constructed wetland environment have rarely been studied in the United States, prompting the need for a method of plasticizer quantification in the Tres Rios Constructed Wetlands which are sustained by the effluent of the 91st Avenue Wastewater Treatment Plant in Phoenix, Arizona. The concentrations of four common plasticizer compounds (dimethyl: DMP, diethyl: DEP, di-n-butyl: DnBP, and bis(2-ethylhexyl): DEHP phthalate) at five sites across the wetland surface water were quantified using solid-phase extraction followed by gas chromatography coupled with mass spectrometry (GC/MS). The sampling period included four sample sets taken from March 2022 to September 2022, which gave temporal data in addition to spatial concentration data. Quantification and quality control were performed using internal standard calibration, replicate samples, and laboratory blanks. Higher molecular weight phthalates accumulated in the wetland surface water at significantly higher average concentrations than those of lower molecular weight at a 95% confidence level, ranging from 8 ng/L to 7349 ng/L and 4 ng/L to 27876 ng/L for DnBP and DEHP, respectively. Concentrations for dimethyl phthalate and diethyl phthalate were typically less than 50 ng/L and were often below the method detection limit. Average concentrations of DnBP and DEHP were significantly higher during periods of high temperatures and arid conditions. The spatial distribution of phthalates was analyzed. Most importantly, a method for successful ultra-trace quantification of plasticizers at Tres Rios was established. These results confirm the presence of plasticizers at Tres Rios and a significant seasonal increase in their surface water concentrations. The developed analytical procedure provides a solid foundation for the Wetlands Environmental Ecology Lab at ASU to further investigate plasticizers and contaminants of emerging concern and determine their ultimate fate through volatilization, sorption, photodegradation, hydrolysis, microbial biodegradation, and phytoremediation studies.
This study examined the differences in mental and behavioral treatment outcomes between use of Telehealth and in-person appointments in effort to mitigate discrepancies that may lessen treatment efficacy.
Refugee women face many challenges to obtaining maternal, reproductive, and sexual health post-resettlement including the language barrier, navigating the healthcare system, finding childcare to attend appointments, and cultural mismatches between their beliefs and practices around the prenatal, childbirth, and postpartum periods and that of the healthcare system in which they resettle into. This cultural barrier poses a challenge to healthcare providers as well as it necessitates that they respect their patients’ cultural beliefs while still providing them with the highest standard of care. Cultural competency training has been used to assist providers in understanding and responding to cultural differences, but gaps still exist when it comes to navigating specific scenarios. The objective of this research was to conduct a literature review of studies pertaining to refugee maternal, reproductive, and sexual healthcare post-resettlement to investigate the following questions: how tensions between biomedically accepted best practices and cultural norms present themselves in these healthcare fields, how healthcare providers take into consideration their patients’ cultural beliefs and norms when providing maternal, reproductive, and sexual healthcare to refugee women, and what can be done to continue to improve the provision of culturally appropriate care to refugee women. Findings from twenty different studies that focused primarily on eight cultural groups identified that Cesarean sections, inductions, and certain family planning methods are significant points of contention regarding cultural norms for refugee women and that they prefer certain foods, birthing positions, and other cultural practices during the delivery. Healthcare providers consider their refugee patients’ cultural beliefs by creating relationships with them built on trust, utilizing community liaisons, and through attempts to accommodate cultural practices when possible. Some potential improvements offered to improve cultural competency were improved cultural competency training that focused on how healthcare providers ask questions and interact with their patients, increased partnership with refugee communities, and an emphasis on patient education surrounding interventions and procedures related to maternal and reproductive health that could cause hesitations. The results of this literature review accentuated the importance of relationships within the field of refugee women’s healthcare, between both refugee patients and their providers and refugee communities and the healthcare systems. Providing refugee women access to more culturally competent healthcare can increase their trust in the healthcare systems of the countries they resettle in and healthcare utilization that can contribute to improved health outcomes for refugee women and their children.
