Burden looks at Guiyu town in China: the world's largest informal electronic waste disposal centre. Waste circuit boards, cathode ray tube glass, and batteries have directly caused the lead (Pb) content in the local soil to be severely exceeded, resulting in the originally fertile land being unable to grow crops.

During the permeation of lead into the soil, at the microscopic level, the lead is not evenly distributed but instead adheres to the surface of soil particles, gradually forming a dense layered structure. This process is similar to the process of gelation, which compresses the originally loose and breathable soil particles, blocking the circulation of air and water, causing the soil to gradually "suffocate" and lose its ecological functions.

The sculpture aims to visualise imperceptible microscopic phenomenon, allowing viewers to observe the pressure exerted by lead metal on the environment and soil. It reveals a slow, continuous and irreversible change that occurs in the soil under the influence of lead metal pollution: once the pollution enters the system, it will never truly "disappear"; it merely shifts and precipitates. We are neither able to accept it or change it.
