Fuzhou will be monitored to ensure that drinking water without rare earth rare earth content

Rare heavy metal great harm to human body

In this context , the department proposed rare earth content Fuzhou source water monitoring research programs , will introduce the emission spectrum of American mass production , monitoring of drinking water in the rare earth content . Rare earth lanthanum (lán), cerium (shì), praseodymium (pǔ), neodymium (nǚ), promethium (pǒ) and other 10 kinds of elements collectively , while emission spectra mass spectrometer can identify most of these different elemental composition slight difference.

It is reported that many rare and iron ore, uranium associated pollutants , heavy metal poisoning. Rare case of excessive inflow of water , the equivalent of heavy metal pollution of water bodies , human intake , it will affect the nervous system , can cause serious and even kidney failure.

Rare earth is divided into light and heavy rare earth, rare earth south mostly light rare earths. Light rare earth mining basic principle is to use ammonium sulfate soaked soil, the REE ionic displacement to the solution, and then precipitated oxalic acid or ammonium bicarbonate rare earth concentrate .

Small workshops brutal exploitation of rare earth , it is likely to cause pollution. Illegal mining of rare earth who dig the mountain , from the foot of pumping , in the Peak dug pond, open perfusion chemicals soak mined. Perfusion of chemicals directly into the ground , mining and soil contamination of sewage water , land .

Some rare earth potential illegal incorporation of water source protection zones

In addition to the rare earth content in the source water to strengthen monitoring , the province has begun to strengthen some rare earth producing water source protection . Reporters learned that, last September , Dong Tong minqing Sakamoto Sakamoto , Xian Ke Yangshan investigated and dealt with under the illegal mining of rare earth ore events. The provincial government approved the agreement last month to designate Township Minqing three other three towns as centralized drinking water source protection areas, which will contain Dong Tong Sakamoto Sakamoto water source protection zones.

According to reports, after the water source protection areas delineated , the film area will be more stringent environmental requirements , which would be better to curb illegal mining of rare earths impact on downstream drinking water .
