Purification effects of riparian wetland in a natural state on pollutants are unstable and are always influenced by hydrology, climate, and extent of wetlands development. For this reason, study of the role of the purification function of riparian wetland in a natural state is ongoing. In this study, with the Kouma section of the Yellow River wetlands as the study area, using the field experiment method and the 15N enriched technique, the agricultural non-point nitrogen pollution control function of Phragmites communis Trin in riparian wetlands was studied. Artificial runoff events enabled the collection of a temporal and spatial array of samples within the wetland so that the plume of runoff water moving through the wetland could be traced and its attenuation determined.

This chapter critically examines English, as well as selected European Union, laws that regulate the interlinked environmental challenges of protecting the quality and quantity of water courses. It deals with legal rules seeking to prevent and limit the pollution of rivers and other inland surface waters, such as lakes, as well as coastal areas and groundwater. One of the key challenges for water pollution law is to evolve into a more holistic, coherent, and integrated pollution control regime. In discussing this challenge, the chapter refers to and critiques recent interesting attempts to develop environmental policy discourses of bioregionalism and ecofederalism, that is, attempts to map regulatory space onto ‘natural’ spaces.

The ‘polluter pays principle’ (PPP) is one of the four principles that govern the European Union's environmental policy. Although PPP justifies Pigovian taxation as a legitimate policy means to internalise externalities, there is a potential contradiction between PPP and Pigovian taxation depending upon the definition of pollution control costs. We summarise this debate and focus on the lump-sum refunding of tax revenues in order to reconcile the PPP and Pigovian taxation. We propose equity as the guiding principle to select among various refunding schemes, and empirically examine a specific application.
