Phosphate rock is a source of heavy metal pollution of air, soil, water, food chain etc, therefore requires removal of heavy metals (HMs) from the rock prior to its use. 展开 关键词: Phosphate rock Atomic Absorption Spectrometry (AAS) Pollutants Heavy metals Pakistan ...
The central lagoon area shows low pollution and a balanced influence of all the sediment components in the metal complexing processes, mostly due to the manganese and iron matrices. The inner canals are very polluted with heavy metals strongly bonded to H2S that form highly insoluble compounds, ...

In the past 30 years, China's economy has experienced rapid development, which led to a vast increase in energy consumption and serious environmental pollution. Among the different types of pollution, heavy metal pollution has become one of the major environmental issues in China. A number of st...
Specificity of heavy metals pollution in index urban soil of Changchun city was studied for the potential ecological hazards. The potential ecological hazard suggested by Hakanson was used to assess the ecological hazards of heavy metals in urban soils. The results showed that urban soils were seriou...
Long-term monitoring of metal pollution by urban trees 2008, Atmospheric Environment Citation Excerpt : Starting from 1990, further measures have been taken in Italy to limit pollution levels increasing; since 1989 “green” fuel and catalytic exhausts have become compulsory, and in 1989, the Rome...
