Aquatic Pollution and Ecosystem Impacts Flashcard

Front

What are nonpoint sources of pollution?

Back

Nonpoint sources of pollution are diffused and difficult to identify, such as pesticide spraying, agricultural runoff, and urban runoff.

Front

What is a major environmental concern with dumping solid waste in the ocean?

Back

Dumping solid waste in the ocean leads to floating islands of trash and endangers wildlife.

Front

How is Severe Acute Respiratory Syndrome (SARS) primarily transmitted?

Back

SARS is primarily transmitted by inhaling or touching infected fluids.

Front

How do persistent organic pollutants travel long distances?

Back

Persistent organic pollutants can travel long distances by moving via wind and water before being redeposited.

Front

What effect does algal bloom caused by eutrophication have on dissolved oxygen levels?

Back

Algal blooms caused by eutrophication decrease dissolved oxygen levels in water.

Front

Define eutrophication.

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae.

Front

What are the primary sources of nutrient pollution in aquatic systems?

Back

Primary sources of nutrient pollution include agricultural runoff, wastewater discharge, and urban runoff.

Front

What is the impact of plastic pollution on marine life?

Back

Plastic pollution can entangle marine animals, be ingested by wildlife, and disrupt ecosystems.

Front

What is bioaccumulation?

Back

Bioaccumulation is the process by which toxic substances accumulate in the tissues of living organisms over time.

Front

What are heavy metals, and why are they a concern in aquatic environments?

Back

Heavy metals, such as lead and mercury, are toxic pollutants that can accumulate in aquatic organisms and pose health risks to humans and wildlife.
