Transcript of Pollution
Provo/Orem, Utah metropolitan area
Light Pollution is defined as the intrusion of artificial light and the alteration of natural light levels in the outdoor environment
Many adverse effects:
Negative health effects for humans
Changes in animal behaviors
Disruption in species interactions
Pollution in the Arctic Marine Ecosystem
Oceanic Plastic Pollution
Air pollution is a prevalent issue in large cities across the world. It is the dispersal of particulates, biological molecules or other harmful materials into theEarth's atmosphere.
Combustion of gasoline
Incineration of garbage
Burning of Fossil fuels
Case Study: China
As Chinese cities undergo rapid urbanization, the amount air pollution increases significantly. Pollution in major cities such as Shanghai and Beijing becomes so dense, blocking the sunlight and preventing plant important processes such as photosynthesis.
Air pollution gives rise to other forms of pollution
In Damascus, Syria, air pollution gives rise another form of pollution known as "soil pollution". In this case, Ozone, from the combustion of motor vehicle and industrial buildings are released into the air and sink into the soil. This affects staple crops and livestock.
is where freshwater rivers and streams meet the ocean
originates from many sources:
Types of Pollutants
Persistent Organic Pollutants (POPs)
Biological Impacts of Pollutants
Importance of estuaries:
Future research suggestions:
Avian impacts of estuary
Infaunal organisms as
Toxic substances released from automobile exhaust, industrial manufacturing and other processes enter aquatic environment through the atmosphere
Effects of Atmospheric Pollution
Introduces foreign airborne contaminants:
- Liver toxicity
- Immune suppression
- Hormone alteration
- Contribute to acidification of bodies of water
- High doses are lethal
- Susceptibility to pathogens
- Reproduction rate reduction
- Reduced ability to produce calcium carbonate shell
Most of the Arctic is not sewered
Effects of Oil Pollution
Persistence of sub-lethal does of oil
Overall effect of spills: change in composition of marine fish community, reducing forage fish biomass, affecting higher vertebrates populations
Transport of foreign species
Suffocation or starvation due to entanglement or ingestion
The Arctic holds the largest gas and oil reserves.
- Blow outs
- Pipe line leaks
- Shipping accidents
What are landfills?
Landfills are a mass of land that is reserved for waste disposal.
Usually consists of a gravel pit and a plastic liner
Landfills are the main area for disposal by humans.
All plastic pollution is discarded by human.
About 80 % of debris in the ocean is plastic, and the amounts of it is only increasing. (Gorman 1993)
Plastics: Bottles, bags, plastic packing materials, net webbing, and many more.
Effects of Landfills
Changes in Animal Behavior/Interactions
Groundwater and Soil
Main cause of contamination due to leachates
Leachate is the liquid waste that comes from the waste within the landfill
Landfills are a major source of greenhouse gases.
Artificial Light on Predation:
- Changes in vertical migration leads to higher predation in Zooplankton
- Insect attraction to light sources leads to higher predation by birds/bats.
- Baby Sea Turtles can be drawn by light sources away from the ocean.
- Tall buildings with light confuse and disorient migrating birds
Casablanca landfill in Morocco
Contamination exceed standard levels for potable and irrigation water
Landfills with no liner have more of an immediate impact on their surrounding environment
Threat to Biodiversity
Light pollution is causing changes in:
Changing the Spectrum of Lighting
Changing the Intensity of Lighting
Maintaing Naturally Unlit Areas
Limit waste that goes into the landfills
Change Duration of Lighting
Reduce Trespass of Lighting
The Right Whale
Near to extinction
Due to their enormous size lead them to starvation.
Population tend to grow slowly due to the amount of time it takes them to reproduce.
Female whales don't become sexually mature till about 10 years & pregnancy takes a year long.
Transport of Invasive species
Plant growth compromised
Ozone causes decreased life span
Growth and sustainability affected
Susceptibility to plant death and disease
Case study: China
Urbanization = pollution
Binding of ozone to greenhouse
Increase in ambient ozone; winter wheat (
Case Study: Syria
Heavy metal and ozone uptake in the soil
Weather station funding
Research in other areas
Sewage pollution causes eutrophication (algae bloom)
Heavy metal contamination
Viral and bacterial contamination

- The presence in or introduction into the ENVIRONMENT of a substance or thing that has a harmful or poisonous effect.
What ways can wastewater create issues in baton rouge?
What ways can it be handled in a safe and controlled way?
Are there any current solutions that can be improved?
Use the straws, tape, craft sticks, paper towel yarn to construct an apparatus to protect a fragile egg from cracking when falling
