Algal Bloom

Front

What is an algal bloom?

Back

An algal bloom is a rapid increase in the population of algae in a water body, often due to excess nutrients like nitrates.

Front

What causes algal blooms?

Back

Algal blooms are primarily caused by large amounts of nitrates and phosphates in runoff from agriculture and urban areas.

What is point-source pollution?

Back

Point-source pollution is contamination that comes from a single, identifiable source, such as a pipe or a discharge outlet.

Front

What is non-point source pollution?

Back

Non-point source pollution comes from multiple sources and is often caused by runoff from land, which carries pollutants into water bodies.

How do high water temperatures affect fish populations?

Back

High water temperatures can reduce the amount of dissolved oxygen in the water, which is essential for fish survival.

Front

What are nitrates and why are they important?

Back

Nitrates are compounds that provide essential nutrients for plant growth, but excessive levels can lead to algal blooms and water quality issues.

Front

What is turbidity?

Back

Turbidity is a measure of how clear water is, affected by suspended particles, which can impact aquatic life.

Front

What pH level is optimal for marine organisms?

Back

A pH level of around 7.4 is considered optimal for most marine organisms.

Front

What is the relationship between nutrients and algal blooms?

Back

Excess nutrients, particularly nitrates and phosphates, can lead to algal blooms by providing the necessary resources for algae to grow rapidly.

Front

How can runoff contribute to water pollution?

Back

Runoff can carry fertilizers, pesticides, and other pollutants from land into water bodies, leading to contamination.
