Abstract: Disclosed herein are methods of assessing a population's health using wastewater samples. For example, the methods assess exposure to pathogens, plasticizers, volatile organic compounds, surfactant, hazardous chemical, nicotine, and/or other environmental toxins. In some aspects, the methods determine the concentration of disease biomarkers, chemical biomarker, certain human hormones, certain genes, pharmaceuticals, illicit drugs, personal care product, pathogens, and/or endogenous mental health markers. In some aspects, the methods assess population health at a neighborhood level. The methods may also be used to assess population health at a larger regional level, for example at a state level or a national level.

Abstract: Methods for sample collection for assessment of air quality include generating an atmospheric condensate from air to be sampled, and collecting the atmospheric condensate in a collection vessel for subsequent use and analysis. Atmospheric condensate may be generated through a heat exchange module, such as a cold trap or the cooling coils of an HVAC system. The collection vessel may be an ultraclean glass jar or a cold trap. Air may be sampled actively or passively for both chemical and biological agents.
