Biogeochemical fluxes through urban residences contribute significantly to the overall biogeochemical cycles of cities and of the nation. However, little is known about how biogeochemical fluxes that contribute to environmental pollution vary among households, nor what factors contribute to that variation. We quantified the fluxes of carbon (C), nitrogen (N), and phosphorus (P) through households along an urban to exurban gradient in the Saint Paul-Minneapolis, Minnesota metropolitan area. Our approach combined a mail survey, household energy records, lawn model, parcel data, and vegetation survey data (used as input to the UFORE model) to quantify fluxes associated with vehicle and air travel, human diet, household landscapes, paper and plastics, and pets. Fluxes of C were dominated by transportation and household energy use. Fluxes of N were dominated by landscape fertilizer use, human diet, and fossil fuel combustion, while P fluxes were dominated by pets, human diet, and detergents. Fluxes of total C, N, and P were highly variable and skewed, indicating that a smaller proportion of households contribute to the majority of total fluxes. Skewed total fluxes were driven by highly skewed fluxes arising from transportation and fertilizer use, while fluxes arising from household energy use and human diet were more normally distributed. These results suggest that policies aimed at mitigating urban biogeochemical pollution need to consider flux patterns; for example, fluxes that are dominated by the activity of relatively few households could be most effectively modified by targeting high emitters. Current research focuses on understanding sociodemographic drivers of fluxes among households.
