Which is NOT an effect of mining and mine drainage?

the pH of the water becomes too high for plants and animals

heavy metals get into the water

the pH of the water becomes too low for plants and animals

How could pesticides get into lakes and streams?

it could be sprayed too close to a stream

rain could wash pesticides into a stream

Which of the following is an effect of excess fertilizer washing into streams and lakes?

algae "blooms", leading to lower oxygen

the pH is too low for plants and animals

increased sediment reduces oxygen

Biological indicators like macroinvertebrates are an indicator of potential poor water quality because

only pollution tolerant macroinvertebrates would be found

they can tell you what the dissolved oxygen is

they wouldn't be there if the water had a high turbidity (cloudiness)

Which of the following factors play a role in dissolved oxygen levels within a water body?

temperature and turbulence of the water

pesticide and heavy metals contamination

Acid deposition is a problem because the acid

falls to the ground with precipitation and can get into water bodies

makes water bodies have a high turbidity (cloudiness)

LD50 is the amount of a substance that

causes 50% of the organisms to die

causes 50% of the organisms to live

causes all of the organisms to die

causes all of the organisms to live

When comparing the toxicity of substances, LD50 is used by scientists because

they are comparing the dosage that will produce death

it keeps 50% of the test organisms alive

it causes acidity to increase strongly over time

Macroinvertebrates such as stoneflies, mayflies and water boatmen require high levels of dissolved oxygen and their abundance is an indication of:

Don't tell us anything about water quality

Invertibrates don't tell us anything about water quality

Which of the following are indicators of healthy water systems?

low temperatures, high dissolved oxygen, and neutral pH

high nitrates, high pH, and low temperatures

Under which condition are large numbers of fish in a lake likely to die?

when the water's dissolved oxygen is low and temperature is high

right after a storm with heavy rainfall

Why does chemical waste need to be disposed of carefully?

It contains heavy metals which build up in the tissues of living organisms.

It encourages excessive plant growth

It depletes the oxygen levels in the water

Too much nitrogen or phosphorus in the water can affect dissolved oxygen in water, what does this cause? Select all that apply

large growth of algae that grows too fast for the ecosystems can handle and leads to algae blooms

Increase in fish and aquatic life

Increases the amount of dissolved oxygen

What is true about LD50? (Select all that apply)

Usually received by mouth or skin contact

is 50% of a test group that dies from a specific dose of that substance

The lower the number the more toxic it is

The higher the number the more toxic
