Cards

Term
Acid Rain
Definition
Rainfall made sufficiently acidic by atmospheric pollution that causes environmental harm, typically to forests and lakes
Term
Sanitary landfill 
Definition

Refuse is deposited and then covered with soil.  

Daily application of the soil cover prevents 

spreading of flies, rats, fire, and paper.

Term
Dump
Definition
A site for depositing garbage
Term
wastewater effluent
Definition
Wastewater effluent is the final product of all earlier treatment processes, and it can be discharged to a stream, river, bay, lagoon or wetland
Term
Wastewater biosolids 
Definition

Sludge that has been treated to ensure that it can be safely applied to land as a fertilizer or soil amendment

Term
Bioremediation
Definition
the use of microorganisms for the decontamination of soil or groundwater. usually involves injecting organisms or oxygen into contaminated zones
Term
Coliform bacteria 
Definition

 commonly used bacterial indicator of sanitary quality of foods and water. They are defined as rod-shaped Gram-negativenon-spore forming bacteria which can ferment lactose with the production of acid and gas when incubated at 35-37°C.[1] Coliforms can be found in the aquatic environment, in soil and on vegetation; they are universally present in large numbers in the feces of warm-blooded animals


Field crops are best

Effluent can not be sprayed on fresh produce

Term
Atmospheric inversion 
Definition
The weather phenomenon in which a layer of warm air overlies cooler air near the ground and prevents the rising and dispersion of air pollutants
Term
Greenhouse effect
Definition

The distinctive heating effect on the Earth's surface due to the gases and carbon dioxide in the atmosphere that trap solar radiation and emit infrared radiation

 

Term
PM-10 
Definition

A standard for measuring the amount of solid or liquid matter suspended in the atmosphere, i.e. the amount of particulate matter over 10 micrometers in diameter


Dust, Smoke


matter 2.5 is small stuff that gets deep into lungs.

Term
BOD 
Definition

(Biochemical Oxygen Demand) -  The amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period


its a problem in lakes if oxygen level gets too low.


difference of two numbers he gives you 

Term

Water Quality Act section 201 

 

WQA section 208 

 

WQA section 404 

 

Definition

Deals with point source pollution regulation


Deals with non-point source pollution regulation


Deals with wetland regulation

 

 

 

Term
Non-point water pollution sources
Definition

Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. The term "nonpoint source" is defined to mean any source of water pollution that does not meet the legal definition of "point source" in section 502(14) of the Clean Water Act.

 

Non-point water pollutants: sources are... city streets, rural homes, cropland, animal feedlot.

Term
Point source water pollution
Definition

: Comes from point sources that are specific, large, identifiable discharge outlets --wastewater treatment plants, industrial or factory drains.  Confined animal feeding operations (CAFO’s) of more than 1000 animal units.

Term

Point sources water pollutants

Definition

1.  Infectious agents

a.  Bacterial diseases

     Typhoid, Cholera, Salmonellosis

b.  Viral disease  -  hepatitis

c.  Protozoa  -  amoebic dysentery

     Cryptosporidium

d.  Parasites  - giardia

2.  Inorganic chemicals

a.  Salts

b.  Nutrients - N and P

c.  Heavy metals - Pb, Hg, Zn, Cu, Cd.

3.  Organic chemicals

a.  Petroleum wastes and spills

b.  Pesticides

c.  Carcinogens and mutagens

4.  BOD  -  "Biochemical oxygen demand"

Decomposable organic residues

5.  Grit  -  Sand, silt, and clay

Term
BMP
Definition

A.  Agricultural BMPs

1.  Proper manure disposal

2.  Fencing of streams

3.  Appropriate irrigation practices

4.  Erosion control

5.  Soil testing

6.  Timing and placement of fertilizer

7.  Correct pesticide usage, IPM5

 

B.  Forestry and recreation BMPs

Road location, avoid riparian zones

Restroom facilities and locations

 

C.  Construction site BMPs

Berms, catchment basins, seeding

 

D.  Urban area BMPs

Road salt disposal, street sweeping, 

pet waste disposal

 

E.  Mining BMPs  

Revegetation  

Drainage retentions basins

Term
Indicator organism in water
Definition

used to measure such things as potential fecal contamination of environmental samples. The presence of coliform bacteria, such as E. coli, in surface water is a common indicator of fecal contamination.

Term
Recycling
Definition

primary- remaking same material from the waste

secondary- waste materials made into different products

Term
CO- terminal
Definition

Headaches, reduced mental alertness, heart attack, cardiovascular diseases, impaired fetal development, death.

Term
PM-10- terminal
Definition

Eye irritation, asthma, bronchitis, lung damage, cancer, heavy metal poisoning, cardiovascular effects.

Term
NOx
Definition

     Small levels - nausea, irritated eyes and/or nose, fluid forming in lungs and shortness of breath

     high levels - rapid, burning spasms; swelling of throat; reduced oxygen intake; a larger buildup of fluids in lungs and/or death

     major respiratory problems

     visual impairment in the area affected

Term
SO2
Definition

 include breathing problems, respiratory illness, changes in the lung's defences, and worsening respiratory and cardiovascular disease

Term
Pb
Definition

Anemia, high blood pressure, brain and kidney damage, neurological disorders, cancer, lowered IQ.

Term
Ozone
Definition

Eye and throat irritation, coughing, respiratory tract problems, asthma, lung damage.

Term
Mercury
Definition

Disruption of the nervous system

- Damage to brain functions

- DNA damage and chromosomal damage

- Allergic reactions, resulting in skin rashes, tiredness and headaches

- Negative reproductive effects, such as sperm damage, birth defects and miscarriages

 

Term
Hydrocarbons 
Definition

lung, skin, and bladder cancers

Term
Asbestos
Definition

may increase the risk of lung cancer and mesothelioma

 

increase the risk of asbestosis

 

pleural plaques, pleural thickening, and benign pleural effusions

 

Term
What are the sources of acid rain?
Definition

1.  Sulfur dioxide (SO2) from fossil fuel combustion and 

smelting operations forms sulfuric acid (H2SO4) in the 

atmosphere.

 

2.Oxides of nitrogen (N0 and NO2) from internal 

combustion engines form nitric acid (HNO3) in the 

atmosphere. NOX

Term

List the detrimental effects of acid deposition and steps that can be taken to deal with this problem.

Definition

Impacts:

1. Lakes - rise in acidity kills animal and plant life in water.

2. Forests - slower growth, injury, death of forests. Forest and soil degradation.

3. Building and artifacts - can damage surface layers of material (paint on a car)


Control:

1. Low sulfur fuels - burn low sulfur content coal = less sulfur → sulfur oxides

2. Scrubbers - are like liquid filters for the gases resulting from combustion. remove 80 -95% of sulfur oxides

Term
What are the advantages of recycling
Definition

conserve limited resources

conserve energy

reduce volume of solid wastes

 

Term
Which wastes are appropriate for land application
Definition

sewage sludge, non-sewage sludge, septage, food processing, and other solid waste

 

Term
What is the fate of wastes applied to land. 
Definition

Nutrients either plant uptake, volatize into atmosphere, or wash into streams causing eutrophication.
