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
26
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
27
Plants need a lot of ____ from the soil.
Nitrogen
28
These changes the soil composition, and yield of crops become lesser
Fertilizers
29
Example of Fertilizers
Ammonia
30
Proper way of nature's way in agriculture
Weeds in corn, rice can be nitrogen-fixing
31
These can kill bugs, weeds, and can flow through irrigation and escape through the river.
Pesticides and herbicides
32
Where does pesticides escape to?
tributaries of a river
33
T/F: Pesticides and herbicides may not kill us but can change compositions in our body.
T
34
What can lead to multiple disasters such as runoff?
minerals extracted from sides of mountains
35
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
36
Two types of mining
* Small scale mining * Large scale/industrial mining
37
What is used in small scale mining which may lead to runoff?
Mercury
38
Mining Less regulated like only mining gold
Small scale mining
39
Mining One problem here is maintaining the safety of miners and runoff
Large scale/industrial mining
40
Untreated s____ can contaminate land and bodies of water
Sewage / Sewage sludge
41
T/F: In urban areas, there are already water treatments for safe drinking water
T
42
Fate and Transport of Pollutants in Soil Pollutants might be washed away by p____, causing little or no harm to the ground
precipitation
43
Fate and Transport of Pollutants in Soil The pollutant, if v____, could e_____ and cause little harm to soil
volatile, evaporate
44
Fate and Transport of Pollutants in Soil Pollutants could infiltrate through the u____ soil, in much the same way as g_____
unsaturated soil, groundwater
45
This refers to increase in concentration of a pollutant from the environment to the first organism in a food chain
Bioaccumulation
46
This refers to increase in concentration of a pollutant from one link in a food chain to another.
Biomagnification
47
This is one of the major contributors to land pollution
Solid waste
48
T/F: Some take years before it becomes eliminated from the environment.
T
49

60
Hazardous Waste Gets corrosive if applied to skin
Corrosivity
61
Hazardous Waste An example of this is lithium ion batteries, which cannot be used to charge aircrafts since it might explode
Reactivity
62
Answer to land pollution
Solid Waste Management
63
Public Health Implications of Improper Sw management
* Aesthetic problems (eyesores, odor) * Clogging of sewers, drains & river * Breeding place of insects & rodents * Surface & groundwater pollution
64
Functional Elements of Solid Waste Management
* Waste Generation * Storage * Collection * Transfer and Transport * Processing and Recovery * Disposal
65
This refers to having a space container for waste instead of dumping trash on top of each other.
Modern Landfill System
66
It is the liquid portion that seeps off waste. There should be a plan that manages this portion.
