Freshwater Pollution
Derivation of the Biotic Indexes of Freshwater Pollution
You have been provided with long term biological data for the four different freshwater sites routinely monitored by SEPA with potentially different levels of pollution. You have also been issued with notes setting out the sensitivity of various species of invertebrates to pollution.
1- Deveron Cabrach, NJ 37855 29144
2- Water of Cruden, upstream of Morissons
3- Mains of Dyce at Pitmedden Industrial Estate
4- Burn of Noss
Your task is to use these materials to:
(i) derive biotic indexes that summarise pollution status of each site
(ii) compare different BI approaches,
(iii) calculate long-term ASPT scores for each site
(iv) critically appraise the use of biotic indexes in freshwater pollution monitoring.
Summarise your findings in a scientific report. The report should not exceed 2000 words and
should be of the following structure:
