Quantifying microbial risks of field-scale struvite production from source-separated urine using first-person videography exposure assessment

This paper quantifies occupational exposures to pathogens in urine during urine collection and processing into fertilizer as well as attendant risks of infection from indirect pathogen exposure. We also detail the microlevel activity time series (MLATS) method, which was used to model disease risks and monitor hygiene. This method employs videography in exposure assessment and is broadly useful for high-resolution modeling of indirect exposures to pathogens.
