metal pollution

From has “the blood lead event” to shock the nation repeatedly “the cadmium rice disturbance”, our country heavy metal pollution alarm sounds repeatedly. 　　"Economical Reference Newspaper" reporter when provincial capital areas and so on Hunan, Liaoning, Inner Mongolia investigates and studies found that our country heavy metal pollution by the atmosphere, the water body to the soil pollution shift, the soil heavy metal pollution was entering one “the centralized frequent period”,homepage designer
poses the threaten seriously safely to the resident health and the agricultural product.
Soil heavy metal pollution aggravating 　　In recent years, blood lead exceeding the allowed figure, urine cadmium exceeding the allowed figure and so on shiyou the report, the heavy metal pollution presented the industry to the agricultural shift, the city to the countryside shift, the surface to the underground shift, the upstream to the downstream shift, pollutes from the water and soil to food chain transfer, by the pollution which accumulates gradually is entering the burst characteristics, chain-like, the regional eruption stage.


Huludao is Liaoning Province heavy metal pollutes one of most serious local. Located at the urban district southeast Hulutao Zinc Factory is the whole city heavy metal pollution “the victimized persons”.
To zinc factory Shang Youshu a kilometer place, ill-smelling sharp aroma headed on. 　　Landlord subdistrict office country fair trade community Director Huo Chunhua told "Economical Reference Newspaper" with zinc factory adjoining to Ma Zhang reporter,unreasonable condition
the zinc factory constructs in 1937, for many years the zinc factory heavy metal emissions has caused the peripheral air, the soil to receive the serious pollution. 　　“what most lets the human be able bear is the zinc factory emissions sulfur acid fume.”
Huo Chunhua said that although compared the zinc factory emissions sulfur acid fume with the peak little to be now many, but when arrived discharged fume, in the community fills intermittently “the blue smoke” to let the human not be able to gasp for breath. To the wet weather, in the community could not see clearly nearly the road. 　　What is more worrying, the heavy metal pollution started by the air, the water body to pollute to the soil pollution shift.
A Liaoning Province September Third Society society investigation report showed that the Liaoning soil contaminated zone mainly distributes around Shenyang, Jinzhou, Hulutao city metal mines and so on and so on heavy industry cities and Chai River lead ore, regarding the heavy industry city and the metal mine is the center, take sewage effluent's rivers as a link, forms the Large expanse of soil contaminated zone. And, Shenyang which and the Jinzhou - Hulutao contaminated zone area by the industrial production,market localization smelting industry forms is big, surpasses 1000 square kilometers, by heavy metal element pollution and so on cadmium, mercury, lead, zinc, the pollution intensity is primarily big.
The above report pointed out that in recent years, as a result of the Shenyang Refinery closure and the Industrial enterprise relocation, the pollution pressure had reduces, but Hulutao area, because the mining industry and metal smelting industry was developed, the environment pressure was stern.
With the Hulutao area faced with similar pressure, but also has Hunan's length, the deep pool area. 　　According to the land resources department an item which carries on with the Hunan Province cooperation demonstrated for the time 6 year Earth ecology chemistry investigation that from the Xiangjiang River Zhuzhou Zhuting section exports the Chenglingji to Dongting Lake, presented one long 250 kilometers, the area the approximately 2058 square kilometer giant soil heavy metal element exceptionally to bring, in the region rough rice, the vegetables, in the water body reed, the freshwater mussel appeared by cadmium heavy metal element exceeding the allowed figure primarily.
Hunan Province land resources plan courtyard foundation scientific research department Director Zhang Jianxin believed that looking from the historical tendency, the soil heavy metal pollution presents the aggravating the situation. 　　It is reported that searched the gain with the 1980s regionalizing the material to compare, now the long deep pool area soil heavy metal contaminated area increased 7 percentage points. But if defers to, Academia Sinica subtropics institute's sample investigation data, Hunan soil heavy metal contaminated area has amounted to 715,000 hectares.
