Endocrine disruptors cause the following impacts to organisms
increased respiratory rate
damage to the cardiovascular system
increased size of individual organisms
birth defects and cancer
Presence of fecal coliform bacteria suggests that
a factory polluted the river
a nearby treatment plant added chlorine to the waste water
the water is safe for drinking
untreated animal waste contaminated the water
Which of the following describe the relationship between D.O. and B.O.D.?
When D.O. decreases, the B.O.D. decreases
When D.O. decreases, the B.O.D. increases
When B.O.D. decreases, the D.O. decreases
When B.O.D. increases, the D.O. decreases
Which water quality test will best determine the disruption of photosynthesis caused by cloudy water conditions from sedimentation?
Temperature
Salinity
Dissolved oxygen
pH
Turbidity
Organic matter like yard waste in landfills is a problem primarily because
there is a high risk of toxic leaching
it contains bacteria that spreads disease
as it breaks down it can dissolve the containment
it produces methane gas
Where would you expect to find the greatest concentration of leachate?
at the bottom of the landfill
at the top of the landfill
throughout the landfill
leachate is not created in a landfill
Bacteria in landfills perform anaerobic respiration as they decompose materials very slowly. This process creates
methane
leachate
CO2
oxygen
Which soil is best to have under a landfill?
sand
silt
clay
loam
Living organism that can cause disease in another organism.
pathogen
carcinogen
teratogen
mutagen
Plague is transferred to humans via
Bites from an infected animal
Pathogens in the air
Infected water
exposure to sewage
How are climate change and pathogens related?
Pathogens are wiped out at a higher rate as global temperatures rise
Pathogens are no longer able to spread to subtropical regions
Pathogens are able to expand their range due to warming temperatures
Integrated Waste Management is a system of steps in a specific order to make the best use of disposed solid waste items (think RRR). Which of the following steps should be considered as a last option?
Landfill
Reduce
Recycle
Incinerating
The presence of which of the following can indicate that water has fecal contamination?
Ozone
Asbestos
E. coli/coliform bacteria
Phosphates
