Pathways to Depressive Symptoms among Former Inmates
-
Drawing on data from the National Longitudinal Study of Adolescent Health (Add Health), we examine the association between incarceration and depressive symptoms among a sample of 13,131 young adults. We find that a history of incarceration is associated with a higher expected rate of depressive symptoms and that this relationship operates most strongly through material hardship. We find no differences in the main effect of incarceration across groups, but we find that the role of certain mediating variables may vary, with marital and employment status being a stronger mediator for males than females, and marriage being a stronger mediator for whites compared to blacks and Hispanics. Our results suggest that incarceration constitutes a potent stressor, but that the pathways to depressive symptoms may differ.

Pharmaceuticals, herbicides, and disinfectants in agricultural water sources
-
Agricultural water withdrawals account for the largest proportion of global freshwater use. Increasing municipal water demands and droughts are straining agricultural water supplies. Therefore, alternative solutions to agricultural water crises are urgently needed, including the use of nontraditional water sources such as advanced treated wastewater or reclaimed water, brackish water, return flows, and effluent from produce processing facilities. However, it is critical to ensure that such usage does not compromise soil, crop, and public health. Here, we characterized five different nontraditional water types (n = 357 samples) for the presence of pharmaceuticals, herbicides, and disinfectants using ultra-high-pressure liquid chromatography tandem mass spectrometry based method (UPLC-MS/MS). We then evaluated whether the levels of these contaminants were influenced by season. The highest level of herbicides (atrazine) was detected in untreated pond water (median concentration 135.9 ng/L). Reclaimed water had the highest levels of antibiotics and stimulants including azithromycin (215 ng/L), sulfamethoxazole (232.1 ng/L), and caffeine (89.4 ng/L). Produce processing plant water also tended to have high levels of atrazine (102.7 ng/L) and ciprofloxacin (80.1 ng/L). In addition, we observed seasonal variability across water types, with the highest atrazine concentrations observed during summer months, while the highest median azithromycin concentrations were observed in reclaimed water during the winter season. Further studies are needed to evaluate if economically feasible on-farm water treatment technologies can effectively remove such contaminants from nontraditional irrigation water sources.
