Rather than pay for an oil change at the service station, justin decides to do the job himself. he drains the used oil
and antifreeze directly into the ground in the alley beside his house. after several years, he notices there are no
more frogs in the pond behind his house. what type of pollution is demonstrated in this real world example?
toxic
sediment
nutrient
bacterial

The answer is: Toxic Pollution

Explanation:

"Toxic pollution" refers to contaminating the surroundings with toxic or hazardous chemicals and wastes. This kind of pollution is dangerous as it causes birth defects and death of organisms.

The problem with Justin's situation above is that, he used the oil and antifreeze DIRECTLY into the ground. Antifreeze is also known as an "engine coolant." This is a toxic chemical that should not be ingested. The frogs from the pond behind his house must have ingested the engine coolant, thus resulting to their deaths. It is said that animals are attracted to its smell, thus they are more prone to ingesting or drinking it.

If you are doing it on your own without going to the service station, it is best to bring the substance to the appropriate facility that disposes it. However, in case you spill it accidentally, you may pour some soap and water so it can be mixed together, thereby reducing its toxicity.
