Final Assignment: Concentrations of Chemicals along Rivers in the Yorkshire Region from 1990 to 2006

on 02|02|2015
Filled under: Final Assignment

The dataset from assignment 2 was used again for this assignment. A slider was used in this assignment to show the concentrations for the years from 1990 to 2006. The data was obtained from the environmental agency. The sizes of the circles indicate the concentration of the chemicals. Different colored circles represent the different chemicals, the chemicals are biology, chemistry, phosphate and nitrates. The mouse click displays the name of the district. Certain years do not have data as shown below. Year 1992 has no figures so there is no output for 1992.

The results show that the dominant chemical between 1990 to 1995 is chemistry with most of it being at Ryedale. The concentrations generally reduce towards Doncaster. This could be as a result of dilution. Towards Doncaster and North Lincolnshire region the prevalent chemicals are nitrates. From 1996-1999 chemistry is high in concentration and thereafter the amount of phosphates increases.
