MUNICIPAL SOLID WASTE
Waste materials produced in biomes, business, schools and other places in a community
WHAT ARE THE 3 METHODS OF HANDLING SOLID WASTE?
- 1. Burning
- 2. Burying
- 3. Recycling
Burning of solid waste
A polluted liquide caused by rainwater falling on a dump that has dissolved chemicals from wastes
Holds municipal solid waste, construction debris, and some types of agriculture and industrial waste
Process of reclaiming raw materials and reusing them to create new products
Any material that can be broken down and recycled by bacteria and other decomposers
WHAT ARE THE 4 MAJOR CATEGORIES OF RECYCLED PRODUCTS?
- 1. Metal
- 2. Plastic
- 3. Glass
- 4. Paper
WHAT ARE THE 3 WAYS INDIVIDUALS CAN HELP CONTROL THE SOLID WASTE PROBLEM?
- 1. Reduce
- 2. Reuse
- 3. Recycle
- (The 3 "R's")
Chemicals that kill crop-destroying organisms
Particles of rock and sand
WHAT ARE THE NAMES OF 3 RIVERS IN CONNECTICUT THAT ALL FLOW INTO THE LONG ISLAND SOUND?
- 1. Connecticut River
- 2. Housatonic River
- 3. Thames River
Are chemicals that provide nutrients to help grow better/they can also cause water to become polluted as it speeds up the growth of algae
An area in which, sediments and dissolved materials drain into a common outlet, such as a river, bay, lake, sound or ocean
Ant change to water that has harmful effects on people or living things.
- Oil is a pollutant that nature can only handle in small amounts/a spill is too large to handle
- Oil spills are the most dramatic form of water pollution
HOW DO BODIES OF WATER GET POLLUTED NATURALLY BY THE FALL OF RAIN?
Water from the water cycle picks up pollutants from the ground and carries them to other bodies of water/when this precipitation accumulation occurs in other bodies of water it can cause natural harm
WHY DO PEOPLE HAVE SUCH A PROBLEM WITH SHORTAGE OF WATER?
- 1. Most of the water is salty
- 2. Lots of water is in the form of ice
- 3. Water is far from area in need
- 4. Pollutants get into safe water
WHAT IS POLLUTION?
Emissions of particles and gases, such as carbon monoxide, released into air from factories
A period when less rain than normal falls in area
The process of helping biodegradable wastes to decompose naturally
A material that can be harmful to human health or the environment if it is not properly disposed of
WHAT ARE THE 4 MAIN CATEGORIES OF HAZARDOUS WASTE?
- 1. Toxic or poison
- 2. Explosive
- 3. Flammable
- 4. Corrosive
WHAT ARE SOME SAFE WAYS TO DISPOSE OF HAZARDOUS WATSE?
- 1. Burial in landfills
- 2. Incineration
- 3. Breaking down by living organisms
- 4. Stroring of liquid wastes in deep rock layers
When oil is refined to make gasoline and other petroleum products, these solid materials are left over
Wastes that catch fire easily that can begin burning at fairly low temperatures
Wastes that dissolve or eat through many materials
Wastes that contain unstable atoms/ the atoms give off radiation that can cause cancer and/or diseases
SHORT TERM AND LONG TERM EFFECTS OF HAZARDOUS WASTES?
- Short term:
- 1. irritation
- 2. Breathing difficulties
- 3. Internal bleeding
- 4. Paralysis
- 5. Coma
- 6. Death
- Long Term:
- 1. Diseases
- 2. Damage Body
