Nutrients
These nutrients act mainly as an energy source for metabolism.
What are carbohydrates?
These substances often taste sour and turn litmus paper red.
What are acids?
What example of pollution did Deji mentioned in class with our class with no windows?
What is fart?
These pollutants accumulate in living organisms over time due to their non-biodegradable nature.
What are persistent pollutants?
The largest contributor to modern air pollution in Canada is this.
What are human activities?
This nutrient is most essential for bone structure, along with phosphorus.
What is calcium?
This is a chemical substance that changes color when exposed to acids or bases.
What is an indicator?
This device removes sulfur oxides from industrial smokestacks.
What is a scrubber?
This element depletes the ozone layer when released into the atmosphere.
What are chlorofluorocarbons (CFCs)?
This process uses calcium oxide to remove sulfur dioxide from industrial emissions.
What is scrubbing?
These inorganic substances are essential in small amounts for a healthy diet.
What are minerals?
A reaction between an acid and a base produces water and a mineral salt.
What is neutralization?
The dose of a chemical required to kill 50% of a population is referred to as this.
What is LD50?
Acid precipitation is caused by compounds emitted from this activity.
What is the burning of fossil fuels?
This term describes pollutants that dissolve or dilute in water.
What is solubility or dilution?
The primary constituents in fertilizers are listed as nitrogen, phosphorus, and this compound.
What is potash (potassium)?
The number on which a hot tub’s pH is recorded as basic range will likely be?
What are 8 to 14?
This phenomenon occurs when excess nitrogen and phosphorus cause algae blooms in water systems.
What is eutrophication?
The harmful environmental impact of DDT is primarily due to this.
What is its persistence in the environment?
Washing clothes and fertilizing lawns can lead to an increase in these nutrients in wastewater.
What are nitrogen and phosphorus?
This type of pollutant, such as DDT, does not break down easily and accumulates in the environment.
What is a persistent pollutant?
The major source of oxides contributing to acid precipitation is this.
What are oxides from the burning of fossil fuels?
This technique uses microorganisms to degrade pollutants at contaminated sites.
What is bioremediation?
These pollutants cause harm to living things when their concentrations exceed this measurement.
What is the LD50 threshold?
The most practical way to address acid rain involves reducing this.
What are harmful emissions?
