This is the Oak Mere continuous monitoring summary report, 1997 to 2000 from the Environment Agency North West. This report focuses on the continuous monitoring programme made by a multi -parameter probe in Oak Mere since summer 1997. From 1999 nutrient and chlorophyll samples were taken when the water quality instrument was serviced. Water level measurements were made since 1998. Moreover, the report shows a summary Oak mere water quality of each year (1997-2000). The physico-chemical parameters and nutrient levels included are: temperature, specific conditions, dissolved oxygen, pH, Depth, secchi disc measurements, chlorophyll a, total Phosphorus, orto-Phosphate, Nitrate, Ammonia, and Silicate.

This is the Impact Assessment of ionising Radiation on Wildlife document produced by the Environment Agency in 2001. This report describes the behaviour and transport of radionuclides in the environment, considers the impact of ionising radiation on wildlife, and makes recommendations on an approach for the Impact assessment of ionising radiation on wildlife for England and Wales. The assessment approach focuses on three ecosystems representative of those considered potentially most at risk from the impact of authorised radioactive discharges, namely a coastal grassland (terrestrial ecosystem); estuarine and freshwater ecosystems. The likely scale of the impact on wildlife is also assessed in light of a preliminary analysis based on this assessment approach. The report demonstrates the behaviour and transfer of radionuclides in a number of different ecosystem types. Particular emphasis is placed on exposure pathways in those ecosystems most likely to be impacted by the authorised discharges of radioactivity within England and Wales. The use of biomarker techniques is reviewed in the report, and their application to the study of exposure to multiple contaminants is discussed.
