Policy makers and regulators are charged with the daunting task of comparing incommensurate environmental risks to inform strategic decisions on interventions. Here we present a policy-level framework intended to support strategic decision processes concerning environmental risks within the Department for Environment, Food and Rural Affairs (Defra). The framework provides the structure by which risk-based evidence may be collated and by assessing the value of harm expressed by different environmental policy areas against a consistent objective (e.g., sustainable development), we begin to form a basis for relative comparison. This research integrates the prior art, examples of best practice, and intimate end-user input to build a qualitative assessment informed by expert judgment. Supported by contextual narratives, the framework has proven successful in securing organizational support and stimulating debate about proportionate mitigation activity, resource allocation, and shifts in current risk thinking.

Modern conventional farming provides Western Europe and North America with reliable, high quality, and relatively cheap supplies of food and fiber, increasingly viewed as a potential source of fuel. One of the costs is continued widespread pollution of rivers and groundwater—predominantly by nutrients. In 1970, in both the United States and UK, farming was focused on maximizing yield and management practices were rapidly modernizing. Little attention was paid to the external impacts of farming. In 2010, diffuse pollution from agriculture is being seriously addressed by both voluntary and statutory means in an attempt to balance environmental costs with the continued benefits of agricultural production. In this paper we consider long-term changes in the concentration and flux of nitrate in five rural UK rivers to demonstrate the impact of agricultural intensification and subsequent policies to reduce diffuse pollution on river water quality between 1970 and 2010.

Concentrations and chiral signatures of polychlorinated biphenyls (PCBs) were measured in outdoor air (using polyurethane foam (PUF) - disk passive samplers) and surface soil samples taken at approximately monthly intervals over 1 year at 10 locations on a rural-urban transect across the West Midlands of the U.K. In both air and soil, concentrations clearly decrease with increasing distance from the city center, supporting the existence of an urban ‘pulse’, that indicate the West Midlands conurbation to be a source of PCBs to the wider environment. Concentrations of PCBs in outdoor air samples in this study are well below those reported previously for indoor air in the West Midlands. This, combined with comparison of chiral signatures in outdoor air and soil with those in samples of indoor air taken in the West Midlands, suggest strongly that the principal contemporary source of PCBs in this conurbation is ventilation of indoor air and not volatilization from soil. Future reductions in PCB concentrations in outdoor air and ultimately human exposure appear best achieved by action to remove remaining sources of PCBs from existing structures.
