We compared the sensitivity of algae and hermit crabs to seasonal shifts in the dominance of continuous sewage discharge vs. pulsed inputs of terrestrial material to a subtropical bay. During periods of low rainfall, when sewage was proportionately more important than diffuse loads from adjacent catchments, algae and crabs provided comparable information on the spatial distribution of N polluti...

Millions of children in polluted cities are showing brain detrimental effects. Urban children exhibit brain structural and volumetric abnormalities, systemic inflammation, olfactory, auditory, vestibular and cognitive deficits v low-pollution controls. Neuroinflammation and blood-brain-barrier (BBB) breakdown target the olfactory bulb, prefrontal cortex and brainstem, but are diffusely present ...

The key benefit of economic (or fiscal) instruments is that they would allow a given pollution target to be met for lower overall cost than traditional regulations a considerable advantage given the perceived high financial burden of regulatory compliance. There are other benefits too. Economic instruments grant firms and individuals greater autonomy in deciding how to meet targets; they create...

One of the major challenges for agriculture is to understand the effects of agricultural practices on soil properties and diffuse pollution, to support practical farm-scale land management. Three conventionally managed grassland fields with similar short-term management, but different ploughing histories, were studied on a long-term research platform: the North Wyke Farm Platform. The aims were...

Diffuse pollution and the presence in waters of so-called emerging pollutants, among others, represent a major global environmental problem [...]

Robert J. Davies-Colley National Institute of Water and Atmospheric Research (NIWA), PO Box 11-115, Hillcrest, Hamilton, New Zealand. ABSTRACT: River water quality is important to uses and values within rivers and also in water bodies downstream. Water quality here encompasses: the physico-chemical attributes important to aquatic life and that vary diurnally (e.g. dissolved oxygen, temperature)...
