residential, recreational
Land pollution increases the risk of h____ h___ to man
health hazard
T/F: In land pollution, it is not just one individual that is affected but the entire population.
T
Soil Composition
- Minerals
- Air
- Water
- Organic matter from plant and animal residue
Soil Functions
Commonly observed for houses
Bearing function
Soil Functions
Commonly observed in agriculture
Production or plant growth function
Soil Functions
This refers to disrupting bacterial functions which can result to less decomposition of soil material
Decomposition or ecological function
Soil Functions
This is one of the occult or hidden functions of soil
Filter function
The soil is one of the filters for w_____.
water
Replacing soil with other materials will result to r____ o____ of chemicals in g_____.
run off, groundwater
Sources of Land Pollution
Accidental c____ s_____
chemical spills
Sources of Land Pollution
Improper disposal of?
chemicals and industrial waste
Sources of Land Pollution
Agriculture, m____ and q_____
mining, quarrying
Sources of Land Pollution
Sewage s_____, h____ solid waste
sludge, household
Sources of Land Pollution
Other sources
- Chemicals that erode over time
- Plastic pollution
This refers to soil contaminants that are spilled onto the surface through many different activities.
Accidental Chemical Spills
Improper Disposal of Chemicals and Industrial Wate
- Factory waste
- Human waste
- Improper garbage disposal
- Chemicals that corrode overtime
Improper Disposal of Chemicals and Industrial Waste
These do not decompose
Plastics
Improper Disposal of Chemicals and Industrial Waste
Found in our blood and feces
Microplastics
Improper Disposal of Chemicals and Industrial Waste
Research in UP Biology to find decomposing bacteria for long-living plastics such as?
sando bags and pet bottles
T/F: We use portions of our lands as dump sites.
T
Examples of lands turned to dump sites in the Philippines
Smokey Mountains and Payatas
Improper Disposal of Chemicals and Industrial Waste
Explosions can happen due to trapped _____ from decomposing.
Methane
Improper Disposal of Chemicals and Industrial Waste
If this is not properly disposed, it can accumulate in soil and affect hormones or risk for cancers
Chemical wastes
In the Philippines, since we don’t have the same balance from the old times and control a lot of the process, what agriculture is used?
brute force agriculture
Plants need a lot of ____ from the soil.
Nitrogen
These changes the soil composition, and yield of crops become lesser
Fertilizers
Example of Fertilizers
Ammonia
Proper way of nature’s way in agriculture
Weeds in corn, rice
can be nitrogen-fixing
These can kill bugs, weeds, and can flow through irrigation and escape through the river.
Pesticides and herbicides
Where does pesticides escape to?
tributaries of a river
T/F: Pesticides and herbicides may not kill us but can change compositions in our body.
T
What can lead to multiple disasters such as runoff?
minerals extracted from sides of mountains
When it rains over the mountains, particularly at mining areas affected with chemicals, it will wash over these chemicals and bring it to our sources of freshwater.
Runoff
Two types of mining
- Small scale mining
- Large scale/industrial mining
What is used in small scale mining which may lead to runoff?
Mercury
Mining
Less regulated like only mining gold
Small scale mining
Mining
One problem here is maintaining the safety of miners and runoff
Large scale/industrial mining
Untreated s____ can contaminate land and bodies of water
Sewage / Sewage sludge
T/F: In urban areas, there are already water treatments for safe drinking water
T
Fate and Transport of Pollutants in Soil
Pollutants might be washed away by p____, causing little or no harm to the ground
precipitation
Fate and Transport of Pollutants in Soil
The pollutant, if v____, could e_____ and cause little harm to soil
volatile, evaporate
Fate and Transport of Pollutants in Soil
Pollutants could infiltrate through the u____ soil, in much the same way as g_____
unsaturated soil, groundwater
This refers to increase in concentration of a pollutant from the environment to the first organism in a food chain
Bioaccumulation
This refers to increase in concentration of a pollutant from one link in a food chain to another.
Biomagnification
This is one of the major contributors to land pollution
Solid waste
T/F: Some take years before it becomes eliminated from the environment.
T
Biggest polluters of plastic
PH and Japan
This is waste arising from domestic, commercial, institutional activities in urban areas
Municipal waste
This is a mix of biodegradable and non biodegradable waste.
Municipal Waste
Municipal Waste arise from d_____, c_____, i_____ activities in urban areas.
domestic, commercial, institutional
This is waste arising from industrial activity and typically include rubbish, ashes, and hazardous waste.
Industrial Waste
Industrial waste arise from industrial activity and typically include r_____, a_____, and h_____ waste
rubbish, ashes, hazardous
Examples of industrial waste
Heavy metals, old computers
This waste poses substantial danger immediately or over a period of time to human, plant or animal life.
Hazardous Waste
Hazardous waste poses s______ d______ immediately or over a period of time.
substantial danger
Hazardous waste will exhibit the following:
- Toxicity
- Ignitability
- Corrosivity
- Reactivity
Hazardous Waste
Ability to explode
Ignitability
Hazardous Waste
Gets corrosive if applied to skin
Corrosivity
Hazardous Waste
An example of this is lithium ion batteries, which cannot be used to charge aircrafts since it might explode
Reactivity
Answer to land pollution
Solid Waste Management
Public Health Implications of Improper Sw management
- Aesthetic problems (eyesores, odor)
- Clogging of sewers, drains & river
- Breeding place of insects & rodents
- Surface & groundwater pollution
Functional Elements of Solid Waste Management
- Waste Generation
- Storage
- Collection
- Transfer and Transport
- Processing and Recovery
- Disposal
This refers to having a space container for waste instead of dumping trash on top of each other.
Modern Landfill System
It is the liquid portion that seeps off waste. There should be a plan that manages this portion.
Leachate
Gas collection of leachate could be used for e____ g_____.
electricity generation
Trash should have a p_____ c____ in an ideal world.
protective cap
