_____ wastes are often exported from developed countries to developing countries.

Salt dome and bed formations, underground caves, and mines are _________.

Metals decompose in ________.

It is the contamination of water bodies

Release pollutants from known locations, such as discharge pipes, that are regulated by federal and state agencies

A combination of pollutants from a large area rather than from specific identifiable sources

The degradation of water quality by any process that changes ambient water temperature

It is the process whereby human activity increases the amount of nutrients entering surface waters

These are water-soluble and are found in fertilizers, which can remain on fields and accumulate, leach into groundwater, or end up in surface runoff and cause algal blooms in surface waters, resulting in decreased dissolved oxygen levels

These are also a component of fertilizers; however, they are not water-soluble, and they adhere to soil particles

Such as bacteria, viruses, and protozoa, can result in swimmers getting sick and shellfish becoming contaminated

A large system of rotating ocean currents of marine litter in the central North Pacific Ocean and is characterized by high concentrations of floating plastics, chemical sludge, and other debris that have been trapped by the currents of the North Pacific Gyre

Formed as a result of marine pollution gathered by oceanic currents as the gyres rotational pattern drew in waste material from across the North Pacific Ocean

These are organic (carbon) compounds that are resistant to environmental degradation through chemical or biological processes or decomposition due to light

Refers to the chemical, physical, and biological characteristics of water and is a measure of the condition of the water relative to the requirements of one or more biotic species and/or to any human need or purpose

It is a broad description for various procedures that are used to analyze water quality

It measures the sum of the bicarbonate, carbonate, and hydroxide ions in the water, which raise the pH

When found in natural water, is regarded as an indicator of pollution

It gives an approximation of the level of biodegradable waste in water

Aquatic vegetation, ranging from phytoplankton to large rooted plants, depends upon carbon dioxide and bicarbonates in the water for growth

If its level is too low, it indicates possible water pollution and shows a potential for further pollution downstream because the ability of the stream to self-cleanse will be reduced

These are a form of bacteria that are found in the intestines of warm-blooded animals; their presence in lakes, streams, and rivers is a sign of untreated sewage in the water

They can get into the water from untreated human sewage or from farms and runoff from animal feedlots

This gets reduced to nitrites, which can be harmful to humans and fish

Occurs in water as an intermediate product in the biological breakdown of organic nitrogen being produced either through the oxidation of ammonia or the reduction of nitrate

These are essential nutrients for aquatic plants, but only in very low concentrations

It measures the total concentration of calcium and magnesium ions in the water

It is a measure of how light is scattered in the water column due to solids that do not dissolve but are small enough to be suspended in the water

When one substance enters completely into another

When one substance just hangs onto the outside of another

Using chemicals and/or cleansing techniques that destroy or prevent the growth of organisms that are capable of infection

Removes clays, natural organic matter, precipitants, and silts from the treatment process

A process that combines small particles into larger particles that then settle out of the water as sediment

Removes inorganic constituents and can be used to remove arsenic, chromium, excess fluoride, nitrates, radium, and uranium

An organ that secretes particular chemical substances for use in the body or for discharge into the surroundings

A network of glands that make the hormones that help cells communicate with each other and is responsible for almost every cell, organ, and function in both humans and animals

These are chemicals that can interfere with endocrine or hormonal systems and can cause behavior, learning and developmental disorders, birth defects, cancerous tumors, and loss of fertility

Used in plastic manufacturing and epoxy

By-product of herbicide production and paper bleaching, and released during burning wastes and wildfires

Used to make plastics more flexible

Used to make electrical equipment, heat transfer fluids and lubricants

It is a place where the land is covered by water, which can be freshwater, saltwater, or brackish water

A shrub or small tree that grows in slightly salty (brackish) water formed by seawater mixing with freshwater in estuaries

It is the increase in the concentration of a pollutant within an organism

It is the increasing concentration of a substance in the tissues of organisms at successively higher trophic levels within a food chain

More commonly known as trash or garbage-consists of everyday items that are used and then thrown away

Paints, chemicals, pesticides, etc

Kitchen wastes, vegetables, flowers, leaves, or fruits

Spent fuel rods and smoke detectors

Glass, metals, paper, and some plastics

Hospital wastes

Are used to break down biodegradable material and sewage sludge in the absence of oxygen

A waste treatment process that involves the combustion of substances contained in waste materials and the conversion of the waste into ash, flue gas, and heat

It is the international trade of waste between countries for further treatment, disposal, and/or recycling

The deliberate disposal of municipal and/or hazardous wastes at sea

Method of waste disposal where the waste is buried either underground or in large piles, and where waste is isolated from the environment until it is safe

Lessening the number of hazardous wastes by substituting and using products that are more "Earth-friendly."

Its molecular structure contains chlorine, which seriously degrades the stratospheric ozone layer

Substitutes fluorine for chlorine, and has less of an impact on the stratospheric ozone layer

Usually a by-product of nuclear power generation and other applications of nuclear fission, such as research and medicine

Contain low levels of radiation and remain dangerous for a relatively short time

Contain high levels of radiation and remain dangerous for a very long time

These are wastes that are unstable under normal conditions

These are wastes from specific industries

These are substances found in the environment that can cause birth defects

These are wastes that are harmful or fatal when ingested or absorbed

A containment technology that forms a barrier between the contaminated media and the surface, protecting humans and the environment from its harmful effects and limiting its migration

Excavated or engineered sites for the final disposal of non-liquid hazardous waste are selected and designed to minimize environmental release

Isolates hazardous waste from the environment by condensing or concentrating it

These are natural topographic depressions, man-made excavations, or diked areas that are used for temporary storage and/or for the treatment of liquid hazardous waste

These stores fluid deep underground in geologically stable, porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer

These are non-containerized piles of solid, non-liquid hazardous waste that are used for temporary storage or treatment

These can occur by producing less waste, converting the hazardous material to less hazardous or nonhazardous substances, and placing the toxic material into perpetual storage

It is land that was previously used for industrial or commercial purposes, may have been contaminated with hazardous wastes, and is commonly found in large urban areas
