Pollutant

* Many pollutants are carcinogens
  - chiral
  - dangerous at concentrations as low as parts per billion
  - toxic or harmful to marine life

* More pollutants create clouds with more number of smaller droplets
  - mean more absorption and scattering of light, resulting in more haze

* Most pollutants contain dioxide
  - sulfur dioxide
  - decrease over time, but a genetically altered organism can become dominant
  - enter streams
  - find in pesticide
  - found in Great Lakes waters originate on land from human activity
* Most pollutants have biodiversity
  - impact
  - indirect impact
  - negative effects
* Most pollutants kill aquatic plants
* Some pollutants affect only small regional areas, while others can travel the globe.
* Some pollutants can cause both short and long term health problems
  - serious health problems
  - damage genes in sperms and eggs
  - have a wide range of effects across different groups
* Some pollutants can interact to form secondary pollutants, called 'smog'
* Some pollutants cause cancer, birth defects, nerve damage and lung damage
  - inflammation
  - come primarily from industrial and municipal wastewater discharges
  - dissolve in rainwater
* Some pollutants enter atmospheres
* Some pollutants find in surround water
* Some pollutants have development
  - multiple air quality standards
  - negative effects on the body
  - lose toxicity when filtered by the forest
  - ultimately fall out of the atmosphere as aerosol particles or acid rain
* accelerate oxidation, and nutritional antioxidants and enzymes slow it down.
* accumulate in the ecosystem, impacting the food chain, water quality, and sediment
  - watersheds as a result of various practices and natural events
* affect all of the abiotic factors on which plants survive
  - cycles in nature which are necessary for our survival
* also come from business, industry, and farm fields
  - flow off streets and parking lots, lawns and golf courses
  - irritate mucous membranes in the nose, throat and eyes
  - kill marine species indirectly by degrading their habitat
  - present a potential hazard to loons
* are classified as primary or secondary
  - common today in runoff and floods
  - filtered from surface runoff, enhancing water quality via biofiltration
  - important determinants of human health
  - the key elements or components of pollution
* become trapped under the layer of warm air.
* build in the waterways.
* can affect brain development, survey finds
  - the quality and production of sperm
* can also affect ecosystems on a smaller scale
  - be a major problem for kids
* can also seep down and affect the groundwater deposits
  - downand effect groundwater deposits
  - be gases, such as ozone, sulfur dioxide, carbon monoxide, and nitrogen oxides
  - come from various sources, including building materials and furnishings
  - dissolve in to the water, stay suspended or lie on the ground
  - enter and leave Lake Michigan in many ways
* can enter the Arctic Ocean through the Bering Strait, between Alaska and Russia
  - water cycle from the air when it rains
  - exist in water in different states
* can harm health, the environment and property
  - the natural biological and chemical processes in aquatic ecosystems
  - include hydrocarbons, heavy metals, and pesticides
  - irritate the respiratory tract and make the person less able to perform aerobically
  - reduce the cognitive abilities of children as well as adults
  - seep into rivers and groundwater
  - speed up or initiate normal precipitation processes
  - take two to three days to trigger an asthma attack
  - travel farthest when they are in solution in a river that is fast flowing
* carried by water are a major threat to cave life
  - in the rainwater react chemically with the mortar between the stones
  - the lowering of an animals resistance to disease
  - water pollution problems
  - tiny particles
* continue to pour into it from agricultural runoffs and industrial discharges.
* created in Florida show up in Canada's high arctic and in Antarctica.
* damage trees.
* diminish oceanic sound, the biota above and below.
* disturb the natural balance of the environment.
* enter rivers and streams as run-off during and after a rain
* enter the atmosphere from either man-made activities or through natural Earth processes
  - environment and are broken down by naturally occurring organisms and events
* fate and transport processes.
  - their way to the catch basins in runoff that picks up oils and sand from streets
* have a harmful result on quality of drinking water, recreation, and aesthetic value
* include carbon monoxide
  - chemicals
  - sediments
  - solid waste
  - toxic substances
* increase as they move up the food chain.
* is waste
* migrate in coastal currents, air flow patterns, rivers, and underground aquifers.
* monitored include ozone, carbon monoxide and particulate matter
  - sulfur dioxide, nitrogen oxides, and carbon dioxide
* often attach to soil and flow with runoff that drains to lakes and ponds
  - have the greatest impact on poor people
* pose particular problems
* range from elevated temperature to dioxins and bioaccumulative chemicals.
* rapidly become diluted and blown away by upper level winds before contacting many trees.
* represents an important problem in soil and biosludge.
* rise on air currents to the ceiling exhaust.
* ruin the beauty of healthy, and clean water habitats.
* swirl near shore.
* taint our air, soil and water - even our mother's milk.
* tend to lower the level of dissolved oxygen.
* travel through a watershed to that common body of water.
* wait to smite salmon at sea.
+ Global dimming, Causes and effects: Climate change :: Environmental issues
  * Air pollutants absorb solar energy and reflect sunlight back into space. The pollutants can also become the core for cloud droplets. Water droplets in clouds fuse around the pollutants. More pollutants create clouds with more number of smaller droplets. The smaller droplets make clouds to reflect more light. This causes more sunlight to be reflected back into space and less light reaches the Earth's surface.
  * Many pollutants have a poisonous effect on the body. Carbon monoxide is an example of a substance which is damaging to humans. This compound is taken up in the body instead of oxygen. That makes the body  and in severe cases may lead to death.
