Pollution Levels and Risk Assessment of Heavy Metals in the Soil of a Landfill Site: A Case Study in Lhasa, Tibet.
Int J Environ Res Public Health

Article Synopsis
- The study focuses on pollution levels and ecological risks of heavy metals in soils around a landfill site in Lhasa, Tibet, highlighting the environmental concerns associated with landfill practices in the region.
- Findings show that while heavy metals like cadmium and arsenic are elevated in soil, overall contamination levels are relatively low, with the majority of areas experiencing light to moderate pollution.
- Health risk evaluations indicate a higher cancer risk for adults in the area, and nearby waste disposal and construction activities significantly contribute to increased heavy metal concentrations, particularly in the southeast part of the landfill site.
Article Synopsis
- The study focuses on assessing heavy metal pollution in the soil surrounding the Luqionggang landfill in Shannan City, Tibet, using methods like the geo-accumulation index and potential ecological risk index.
- Results show that the soil has a strong alkaline average pH of 9.37, with mercury (Hg) and nickel (Ni) exceeding background levels, while other heavy metals remain within safety standards.
- The findings indicate that heavy metal pollution is most significant in the western area of the landfill, with Hg posing the highest ecological risk, categorizing the overall pollution level as moderate.
Waste incineration is a process of full combustion reaction between waste and oxygen at high temperature. It is a new problem whether the special natural environmental conditions of Tibet Plateau, such as low air pressure, low oxygen content, and low temperature, will affect the waste incineration in the plateau area. In this work, the influence of different parameters on MSW incineration efficiency and flue gas emission were investigated.
