Effects on greenhouse gases of the application of MBT output, bio-solids and compost on land


By Anna-Maria Skartsila: September 2010

Supervisors: Dr Nick Voulvoulis and Dr Martin Head


This project aimed to investigate the effect on greenhouse gases (GHG) emitted by soil, following the application of bio-solid wastes to the soil’s surface. The four main project objectives were:

Testing soil pH

Assessing soil data from sites in London to identify links to key indicators for characterising soils

Supervisors: Dr Nick Voulvoulis & Dr Martin Head
Collaborator: Ms Dee Flight (British Geological Survey)


This project assessed soil data from sites in London generated through the OPAL soil and earthworm survey and compared it with the existing BGS soil observation dataset. Key indicators were identified which could enable the broad characterisation of soils using public participation surveys.

Flame retardants in lakes – pioneering OPAL research


Flame-retardant chemicals are useful in preventing fires, but they can also travel long distances in the air and damage the growth of animals.

OPAL Water Centre research has discovered flame retardants in a number of English lakes, and a significant concentration of one particular flame retardant in some fish.

OPAL Water research data


How healthy are our lakes and ponds?

OPAL monitored the health of nine lakes and ponds across England, looking at water quality, how it's changing, and how the plants and animals are being affected.

We collected physical, biological and chemical data at three-month intervals to explore how things changed over time, research which is being used to help the conservation of ponds and lakes.
