Leukocyte Esterase. Leukocyte esterase is an enzyme present in most white blood cells (WBCs). A few white blood cells are normally present in urine and usually give a negative chemical test result. When the number of WBCs in urine increases significantly, this screening test will become positive.
Land subsidence occurs when large amounts of groundwater have been withdrawn from certain types of rocks, such as fine-grained sediments. The rock compacts because the water is partly responsible for holding the ground up. When the water is withdrawn, the rocks falls in on itself.
Scotland is still experiencing this springboard effect while southern Ireland, Wales and England continues to sink. The new study shows that land levels could rise by up to 10cm in some areas of Scotland over the next century, offsetting the effects of sea level rise caused by global warming.ut in parts of England, where the land is set to sink by up to 5cm over the next century, it could add between 10 to 33 per cent on sea level rises. The map is the most accurate projection of land subsidence in the UK ever compiled.
