Daqing Wetland was contaminated by heavy metals for holding lots of industrial and domestic waste water. Due to their high stability and non-degradation, heavy metals are possible to gather in human body through the food chain and then threaten health. Water samples were collected from Longfeng Wetland and lake marshes in the vicinity of Daqing City. The contents of heavy metals （Cd, Pb, Cr, Cu, Zn, Ni） were determined, and the contamination degrees were evaluated simultaneously. The results indicate that heavy metals of Zn, Ni, Cd, Cr and Pd have contaminated the Longfeng Wetland severely. In addition the concentrations of Cr and Cd in some lakes around oil wells are excessively high, and have overrun the grade V based on the threshold values of surface water given by the National Environmental Protection Agency of China. Some measures have to be taken to tackle heavy metal contamination of Longfeng Wetland and lake marshes in Daqing City.

It is very common for similar granitoids to be emplaced in the same tectonic region， with some being metal-fertilized while others are barren. The reasons for this are still not clear. Here， we take the Shangcheng pluton as an example. This pluton occurs close to the giant Shapinggou porphyry Mo deposit， and we use amphibole and biotite geochemistry as sensitive tracers to explore this issue. The Shangcheng granitoids comprise the Sigudun （SGD） and Shiguwa （SGW） units， with emplacement ages ranging from 140 ± 3 Ma to 134 ± 2.4 Ma， as revealed by titanite U-Pb dating. The geochemical data of amphibole and biotite indicate that the magma intruded from depths of ～3.3 km to ～2.3 km with increasing oxygen fugacity. The modeled results indicate that water content is an essential factor for metal fertilization， as the Shangcheng pluton has a lower water content than the Shapinggou Mo-bearing granite. The Shangcheng pluton is also characterized by fluorine-poor conditions， with lower halogen fugacity values of IV（F） and log (f H2O/f HF)fluid. In contrast， the increasing Y/Ho and Nb/Ta ratios of the Shapinggou Mo-bearing granite indicate the F-rich nature of the fertilized Shapinggou magma， and its lower Zr/Hf and K/Rb ratios suggest a greater magma differentiation. Therefore， water-poor and F-poor magma， in combination with low-degree fractional crystallization， may be the major controlling factors responsible for the Mo-barren nature of the Shangcheng pluton.
