Yunfu pyrite deposit bearing thallium (Tl) with proven reserves of three million tons' Tl in Guangdong Province, China has been extensively exploited since 1970. This study investigated contamination levels of Tl and other trace metals in ecosystem such as soils, surface waters, vegetables and crops in the area near the deposit. Results show that Tl in these samples nearby has greatly enriched and...
The effects of two earthworm species (Eisenia foetida and Allolobaphora caliginosa) on the bioavailability of Zn or Pb were studied in three soils (Cinnamon soil, Aquic brown soil and Acid brown soil) spiked with 200 mg kg-1 Zn or 400 mg kg-1 Pb, respectively. The results showed that Eisenia foetida and Allolobaphora caliginosa were tolerant to Zn or Pb. but the growth of earthworms was adversely...
This study discusses the feasibility of sequential combination of soil washing and chemical stabilization, through investigating the metal mobility in the treated soils. Results indicate that the washing can facilitate to chemically stabilize metals, if the soil has substantial labile fractions to be removed by washing. However, if the labile metal fraction is negligible, an opposite effect is often...
