In more recent studies, Feng et al. (1999) calculated a Th water column residence time of 2 to 12 days in the Hudson River estuary. McKee et al (1986b) determined that " Th was removed on a time scale of a day or less in the very particle-rich environment of the Yangtze River estuary. In the Amazon River estuary, another particle-rich environment, McKee et al. (1986a) determined that the residence time of dissolved " Th ranged from 2 to 4 days. McKee et al. (1986a) also calculated apparent distribution...

It is seen from the contents of heavy metals in stream sediments, soils and suspended matters for the main basins of the Anhui section of the Yangtze River that the contents of heavy metals in suspended matters are obviously higher than those in stream sediments and soils, indicating that the suspended matters are the main carriers for long distance migrations of heavy metals in the Yangtze River basin. 

Table 2 lists the year-output flows of heavy metals for the main tributaries of the Anhui section of Yangtze River. 

To track the sources of the geochemical anomalies of heavy metals in suspended matters along the Shun an River basin (one of the main tributary basins of the Anhui section of the Yangtze River basin), a rock survey was conducted on typical ore deposits and outcrops of main strata and geological bodies along the Shun an River basin. The results shown in Table 3 indicate the largest source of Cd in suspended matters on the Shun an River basin is endogenetic deposits, especially Pb-Zn deposits. 

The age-determination results by using 210Pb and 137Cs for the sedimentary columns of the alluvia beds along the trunk stream and main tributaries of the Anhui section of Yangtze River show that the variations of the contents of Cd and other heavy metals were basically corresponding closely to major historical events, say the establishment of PRC, the exercise of the policy of reformation and opening and the course of extensive industrialization, etc. 

The experimental results obtained by Chinese scientists obviously show that the areas suffering from acid rain in China have extended northwards from the south of the Yangtze River in 1986 to the whole East China at present. The statistical results from the Acid Rain Survey in 82 cities from 1991 to 1995 indicate that the annual average pH value of the precipitation was lower than pH 5.6 in nearly half of these cities or in 87% of the southern cities, which are located in the south to the Qingling... 

It can be seen that most areas sensitive to acid deposition are in Southeast China, and that insensitive areas are in the Northwest. The sensitive areas, including the catchment of the Changjiang (Yangtze) River and the wide areas to the southward, are... 

As we can see from this map, sulfur deposition exceeds critical load in a wide land area that amounts to 25% of total Chinese ecosystems, which mainly refers to the southeast of China. Among these areas, the exceedances are especially serious in the lower reaches of Changjiang (Yangtze) River, in the Sichuan River Basin, and in the Delta of Zhujiang River.
