Q: what areas in the world are being affected by acid mine drainage?
I wanted to know…what areas specifically in the world are being affected by acid mine drainage? what effects does acid mine drainage have on soil? what are some websites that show affected areas?

A: Anyplace where there is coal or metal ore mining. In the USA it is the Eastern 1/3 and the middle of the north ( Montana, Dakotas, Idaho, Minnesota).

Q: What is the function of a wetland and how does it relate to Acid Mine Drainage?
Be sure to in clude the pros and cons of a wetland. DON’T GET THIS FROM WIKIPEDIA. I already looked there.

A: A wetland is a place created to preserve wildlife, and make sure they have place to live. If it is built to close to a mine or industrial business, it could become contaminated. Wetlands are good if you like wildlife and nature. Wetlands are bad to investors who would rather build on the property.

Q: what are the natural chemical processes by which dissolved trace metals are removed from acid mine drainage?
Trace metals in geochemistry is defined as ‘all elements except the eight abundant rock-forming elements: oxygen, silicon, iron, calcium, potassium, and magnesium’

A: Carbonate neutralization:
Generally, limestone or other calcareous strata that could neutralize acid.
Ion exchange:
ion exchangers would remove potentially toxic heavy metals from mine runoff.
Wetlands:
A spectrum of bacteria and archaea, in consortium with wetland plants, may be used to filter out heavy metals and raise pH. Anaerobic bacteria in particular are known to be capable of reverting sulfate ions into sulfide ions. These sulfide ions can then bind with heavy metal ions, precipitating heavy metals out of solution and effectively reversing the entire process.
Precipitation of metal sulfides

Q: What culture media is most appropriate for growing sulfate-reducing bacteria from acid mine drainage?
i jst want the direct method not the general media. i want to know if SRBs are present in the water sample that im going to collect from Acid mine drainage.
stor5 ill check up on it. the ones i found on the net says either i use SRB medium or desulfovibrio medium. they never even mentioned about actate-sulfate medium. LOL. one more option added.

A: EDIT:
I had to call up my friend and ask him:) Actate-sulfate media is what he say’s to use. He is a Microbiology teacher, and he says it’s a little expensive, but it should do.

If you are using the media for the general purpose of identification why not use selective media? If it is for a report or something of the sort, I’m sure the teacher won’t mind.

Q: what is the iron charge in acid mine drainage?
Acid Mine Drainage (AMD) in a deep mine is green in color because of the ionic form of iron in that water. What is the charge on the iron in the reduced state as ions in the AMD?
a.) 0 b.) -1 c.) +2 d.) +3

A: C. +2

Q: List some commonly mined ore bodies that pose an acid mine drainage risk in BC?

A: Do your own homework.

Q: Acid Mine Drainage?
What is the chemical nature of acid mine drainage and what exactly is it in the AMD that is toxic to organisms such as fish ?

A: See the link below. In a nutshell, what you end up with is sulfuric acid which lowes the pH of aqueous solutions and makes the environment highly toxic. Sulfuric acid is also known as “battery acid”.

Q: How to determine iron and sulfur oxidizing bacteria?
How would you determine whether acid mine drainage from an abandoned coal mine
in SE Ohio contains iron and sulfur oxidizing bacteria?

From my microbiology days I know that these are not organisms that grow colonies on solid media. Other than that I need some direction. Any little bit helps! Thanks!

A: hmmm well you could test the drainage for iron or sulfur. If the sample did contain iron/sulfur oxidizing bacteria, then one would not expect to find any in the sample (the bacteria would eat it all up).

Q: Which of the following is NOT an environmental impact of mining.?
Enrichment of waterways

groundwater depletion

erosion

acid mine drainage

air pollution

Thanks for the help if you can
this question is kind of confusing for me.

A: Wow if this isn’t a loaded question I don’t know what is! Your green party teacher/professor is looking for enrichment of waterways for his/her answer. They are convinced that absolutely nothing good can come from mining, only the destruction of mother earth, which is as absurd as your teacher…

Q: help with my english assignment plz any1 im in yr 8?
i need to make this paragraph like, 2x longer. any1?

Contaminants
Contaminants are organic or inorganic pollutants that pollute our water. Organic substances are natural chemicals that can contaminate the water, such as bacteria, oil, food processing waste and gasoline. Inorganic chemicals are man-made substances such as fertilizers, acid mine drainage and chemical wastes. Other pollutants are rubbish, sewage, and basically anything that damages the water.
contaminants – things that pollute water
organic waste – natural chemicals
inorganic – man made pollutants (fertilizer, etc)

A: Contaminants are organic or inorganic pollutants that pollute our resources. The most commonly polluted resource is water. Organic substances are natural chemicals that can contaminate the water, such as bacteria, oil, food processing waste and gasoline. Inorganic chemicals are man-made substances such as fertilizers, acid mine drainage and chemical wastes. Other pollutants are rubbish, sewage, and basically anything that damages the water. These pollutants can reduce the biodiversity of the water by killing the animals and plants that live in it. This has a huge effect on the ecosystem.

Fertilisers especially are a problem, because when they reach the water they cause algae blooms. Once the algae dies, the bacteria feeding off it use up all the oxygen in the water, which kills the animals that live in the pond. This happens worldwide in rivers, lakes and dams.

Another big problem is the chemical waste. Some of this is poisonous, and though the amounts in the rivers are too small to kill each individual fish, the birds that feed on the fish might be affected, or in extreme cases, the humans that feed on birds that eat the fish.

Hope that helps

Q: glossary: write a brife definition of the following terms?
1.acid mine drainage
2.aquatic
3.biome
4.atmosphere
5.biodiversity
6.buffer zone
7.ecotourism
8.endangered
9.ground water
10.predator
11.toxin
12.waste water
yes i am sure about the brife definition
brief* definition

A: There are too many listed to answers your questions so I will choose one. That would be # 10..Predator.
.
Answer: My ex…predator always looking for $$$$,
Now, go do your homework and look uip your own “breif” discriptions…dumb, dumb.

Q: 10 POINTS FOR BEST ANSWER!!!!!!PLLLEEEAASE ANSWER AS BEST AS YOU CAN?
do you know the answer to the following multiple choice question:

Pesticides,fertilizers,soil,and weed killers are all forms of:
A.)abandoned mine drainage B.)agriculteral runoff
C.)acid rain D.)industrial waste

THANK YOU AND I APPRECIATE ANY EFFORT:)

A: I have a feeling this is your homework, but I wanted to give you a tip for questions like this.

The answer is B, but why is it B?

Think about where they use pesticides, fertilizers, soil and weed killers. It isn’t in abandoned mines or any industrial sites. You know that it is obviously not acid rain.

Those are all things used on farms, yards, etc. AGRICULTURAL items.

So it makes sense that it would be agricultural runoff.

Break down your question and knock off the ones you know are definately wrong.

Just letting you know so when you have your test later on in the week, it may help ;-P

Q: What mass of acid is produced from the reaction of 1.50 kg FeS2 with 1.50 kg O2 and 250 g H2O? Given: Equation?
Acidic water drainage from abandoned coal mines results from the oxidation of iron sulfide according to this reaction:

2 FeS2 (s) + 7 O2 (g) + 2 H2O (l) → 2 FeSO4 (aq) + 2 H2SO4 (aq)

What mass of acid is produced from the reaction of 1.50 kg FeS2 with 1.50 kg O2 and 250 g H2O?

A: Moles H2O ( limiting reactant) = 250 g / 18 g/mol= 13.9
= moles H2SO4
Mass H2SO4 = 13.9 mol x 98 g/mol=1362 g
