Background: Little is known about the effects of pesticides on children's respiratory and allergic outcomes. We evaluated associations of prenatal and current pesticide exposures with respiratory and allergic outcomes in children from the Infants' Environmental Health Study in Costa Rica.

Methods: Among 5-year-old children (n=303), we measured prenatal and current specific gravity-corrected urinary metabolite concentrations of insecticides (chlorpyrifos, pyrethroids), fungicides (mancozeb, pyrimethanil, thiabendazole) and 2,4-D.

In a transdisciplinary project with the Municipality of Trelew (Argentina), we assessed barriers to households disposing of separated waste, developed supportive behavioral interventions, tested the interventions in a randomized controlled trial, and supported the Municipality in upscaling the most successful and cost-effective intervention to a total of 20,000 households. The interventions were designed to address the three main barriers to waste separation detected through a baseline study: a lack of knowledge on how separation works; the additional hassle it represents; and the self-regulation challenge it poses. The interventions consisted of envelopes containing simplifying information, empathetic messages, a magnetic calendar acting as a reminder, or a combination thereof.
