What are the three main hazards of hazardous materials?
Another system, outlined in NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response,3 identifies hazards by the severity of the hazard in three principal categories (health, flammability, and instability).
Is an introduction to hazardous materials?

What is the primary hazard associated with most flammable liquids?
Explosion
Which of the following has the highest priority at a hazardous materials incident?
A. The safety of responding personnel is the highest priority in all actions taken to control or mitigate hazardous materials incidents.
Is difficult and sometimes impossible to purify contaminated groundwater?
Groundwater, defined as water moving through soil and rock, is a common route for chemical movement. Also, chemicals in the groundwater last longer; chemicals cannot evaporate, and they resist breakdown in the absence of air and light. It is difficult and sometimes impossible to purify contaminated groundwater.
What are the four routes of entry for toxic substances?
Exposure to chemicals may occur by the following routes:
- inhalation,
- ingestion,
- contact with skin and eyes, or.
- injection.
Which federal law is intended to ensure so far as possible safe working conditions?
The Occupational Safety and Health Act
What is the basic approach to cleaning contaminated soil?
The basic approaches to cleaning contaminated soil include: Containment, off-site containment, on- or off-site treatment, or disposal. Air stripping/aeration, activated carbon, and chemical precipitation.
How do you fix contaminated soil?
According to the EPA, “Treatment approaches can include: flushing contaminants out of the soil using water, chemical solvents, or air; destroying the contaminants by incineration; encouraging natural organisms in the soil to break them down; or adding material to the soil to encapsulate the contaminants and prevent …
How do you decontaminate soil?
Adjusting the soil pH to as close to neutral as possible will help reduce the negative impact of contaminants. Contaminated soil treatment also includes adding plenty of rich organic matter to the soil and a healthy top-dress of peat moss, compost, or aged manure. This practice will help protect plants from damage.
What is the process of phytoremediation?
Phytoremediation is a bioremediation process that uses various types of plants to remove, transfer, stabilize, and/or destroy contaminants in the soil and groundwater. In this process, the plant releases natural substances through its roots, supplying nutrients to microorganisms in the soil.
Which bacteria is used in phytoremediation?
In recent years, phytoremediation assisted by plant growth-promoting bacteria (PGPB) has been highly touted for cleaning up toxic metals from soil. PGPB include rhizospheric bacteria, endophytic bacteria and the bacteria that facilitate phytoremediation by other means.
What is used in phyto remediation?
Phytoremediation is a plant-based approach, which involves the use of plants to extract and remove elemental pollutants or lower their bioavailability in soil (Berti and Cunningham, 2000). Plants have the abilities to absorb ionic compounds in the soil even at low concentrations through their root system.
How does Phytoaccumulation work?
Phytoextraction (or phytoaccumulation) uses plants or algae to remove contaminants from soils, sediments or water into harvestable plant biomass (organisms that take larger-than- normal amounts of contaminants from the soil are called hyperaccumulators).
Which process is toxic to plant?
The heavy metals that plants extract are toxic to the plants as well, and the plants used for phytoextraction are known hyperaccumulators that sequester extremely large amounts of heavy metals in their tissues. …
Which is the drawback of phytoremediation?
Disadvantages: Phytoremediation simply relocates toxic heavy metals, it does not remove them from the locale. Phytoremediation is limited to the surface area and depth occupied by the roots. Slow growth and low biomass require a long-term commitment.
What are the disadvantages of Phytoextraction?
As with all remediation techniques, phytoextraction has a limited effectiveness. Its two main limitations are: metal toxicity to plants at high concentrations and the cost to dispose of the plant tissues.
What are the advantages and disadvantages of Phytoextraction?
ADVANTAGES | DISADVANTAGES |
---|---|
Bioleaching is in general simpler and cheaper to operate and maintain than traditional processes. | The bacterial leaching process is very slow compared to other methods. |
What organisms are used in bioleaching?
Bioleaching can involve numerous ferrous iron and sulfur oxidizing bacteria, including Acidithiobacillus ferrooxidans (formerly known as Thiobacillus ferrooxidans) and Acidithiobacillus thiooxidans (formerly known as Thiobacillus thiooxidans). As a general principle, Fe3+ ions are used to oxidize the ore.
What organisms are used in Phytomining?
Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining).
What is Phytomining good for?
Plants absorb metal ions through their roots in a process called Phytomining . It removes toxic metals from contaminated soil – around old mines for example. In the future, when supplies of higher grade ores have run out, metals might be extracted by burning the plants to produce ash.
What are the stages of Phytomining?
Phytomining has several stages:
- Plants are grown in an area with low grade ores where they take in the minerals through their roots.
- The plants are then burned.
- The ash is added to water and the minerals dissolve in that water.
- Electrolysis is then used to extract the metal from the mineral.
What type of plants does Phytomining depend on?
Phytomining is the production of a `crop’ of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced.
