heavy metal pollutant

Growth of certain salt-marsh plants appears to be inhibited by heavy metal pollutants.

Soil analyses have indicated the presence of heavy metal pollutants, probably due to the area's use as a dump.

The proposal gained more attention in 2007 when asbestos and heavy metal pollutants were confirmed to be present on the site.

Concentrations of two other heavy metal pollutants, cadmium and zinc, were more than halved during the same period.

It also assesses the sink capacity of soils for heavy metal pollutants and major environmental issues related to organic farming.

Furthermore, all cane burning should be the su bject of investigation to identify heavy metal pollutants attributable to agricultural chemicals.

Although not included in the tables below for each facility, another heavy metal pollutant emitted by coal-powered generators is lead (Pb).

Twenty-five blubber cores were collected this summer, which will be analysed for organochlorine and heavy metal pollutants by Dr.

In water purification, chalcogels have shown promise in absorbing the heavy metal pollutants mercury, lead, and cadmium from water.

Microbial communities in natural waterways and soil systems play an important role in the catabolism and sequestration of organic and heavy metal pollutants.

Therefore, removal and replacement of the bioretention layer will become necessary in areas with heavy metal pollutants in stormwater runoff to extend the life of the treatment system.

Majority of heavy metal pollutants are likely to be present in a close proximity range of 0.5 km from the creek mouth after which there is a steady decline in their concentration up to 1.5 km.

Canada also signed a protocol on heavy metals under the UN/ECE Convention on LRTAP, which has reporting requirements for three heavy metal pollutants - lead, mercury and cadmium.

Dr. James Davis, a professor of chemistry at the University of South Alabama, gives the example of designing an ionic liquid that is able to bind with heavy metal pollutants like mercury and cadmium.

Adsorption capacity, which is defined as adsorption content of heavy metal pollutant by unit volume of (muddy) water, increases with an increase in either the suspended sediment concentration or initial dissolved heavy metal concentration.

Adsorption contents of heavy metal pollutants on unit weight of sediment (the suspended particulate heavy metal concentration) decreases with increasing suspended sediment concentration and can be well explained by the law of mass conservation.

Significant levels of chloride (one of the main components in salt) can "alter the soil 's pH chemistry and elevate levels of heavy metal pollutants, while at the same time causing a loss of soil structure and killing off micro-organisms".
