1
the process whereby a substance is changed from one chemical to another (transformed) by a chemical reaction within the body. Minamata disease is an example of this.
2
The incremental increase in a contaminant's concentration at each level of the food chain.
3
Occurs when an organism absorbs a toxic substance at a rate greater than that at which the substance is lost.
4
______ compounds that contain carbon, chlorine, and hydrogen. Their chlorine-carbon bonds are very strong which means that they do not break down easily. They are highly insoluble in water, but are attracted to fats. Since they resist metabolism and are readily stored in fatty tissue of any animal ingesting them, they accumulate in animals in higher trophic levels.
5
when the environment becomes enriched with nutrients. This can be a problem in marine habitats such as lakes as it can cause algal blooms.
6
Acid rain causes the ________ of soil.
7
an unstable form of a nuclide. They may occur naturally, but can also be artificially produced. Can be found in drinking water.
8
microscopic solid or liquid matter suspended in the Earth's atmosphere.
9
____ hydrocarbons are hydrocarbons that contain halogen carbons. An example is CFC. This is a water pollutant.
10
___ deposition is the pollution of water caused by air pollution.
11
The chemical versions of these increase the amount of nitrogen and potassium in the soil, stripping it of nutrients and killing the microbes in it.
12
Land-based ______ of human-made debris comprise the largest source of marine debris in oceans world-wide
13
Herbicides, insecticides and fungicides are examples of this soil pollutant that causes damage to the top layer of soil.
14
Cause of water pollution: erosion from mining, forestry, farming, and other land-use; coastal dredging and mining
15
Pollutants can disrupt the human _________ system, causing infertility and cancer.
16
Altering of the natural environment by human activities resulting in the contamination of land, air and water by harmful substances.
17
When these compounds mix with oxygen and water, you will get nitric acid.
18
Plankton blooms are formed by this sort of water pollution.
19
____ oil drilling causes oil seepage into the water.
20
Photochemical ______ are secondary air pollutants formed under the influence of sunlight by complex photochemical reactions in air which contains nitrogen oxides and reactive hydrocarbons as precursors.
21
The are biological, physical and ______ pollutants.
22
____ organic compounds are organic chemicals (contain carbon) that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air.
23
Toxic non-metals like chlorine and fluorine that form acids when combined with hydrogen.
24
When these oxides combine with water, you will get sulphuric acid.
25
____ pollution is the degradation of water quality by any process that changes ambient water temperature.
26
Apart from lead, a type of toxic metal. A neurotoxin produced by coal-fired power plants.
27
When there is a algal bloom, there is depletion of oxygen, resulting in ____ conditions, causing organisms to suffocate.
28
___ from agricultural land (and even our own yards) can carry excess nutrients, such as nitrogen and phosphorus into streams, lakes, and groundwater supplies. Main cause of oil seepage into waters.
29
____ issues deal with conservation and wildlife
30
___ issues deal with waste management, recycling, pollution, etc...
