OBJECTIVE
The aim of the project is to investigate quality of waters (rivers (i.e.,
the Brahmaputra, Indus and the Ganges), lakes and precipitation)
on Himalaya region of Tibetan Plateau in the background of climate
change.

2. Practical scheme
Research program on climate change (FICCA)
#1 Climate change based
on ice core study — an
increasing temperature
happened over the last 500
years
(Zhang et al.,2014, submitted)

#2 Waters study in rivers and lake of Tibetan Plateau —
atmospheric pollution from surrounding areas could affect the water
quality. Some elements (such as arsenic) concentrations in rivers were
higher than that of WHO guideline for drinking.Result

Outlook
3. Achievement

Seasonal variations of dissolved trace metal levels of Lhasa
River (a) and Duilong Qu (b). (Li et al., 2014)
#3 Effect of climate change on
water chemistry — stream
water emanating from one
glacier of Tibetan Plateau
showed that Ca2+, HCO3- and
SO42- are the key ions in stream
water throughout the ablation
season, and the water chemistry
are affected by temperature
significantly.
