Why Monitor the Environment? (HSC SSCE Chemistry): Flashcards

Substance causing undesired environmental effects

Upper atmosphere (absorbs UV radiation)

Waterway enrichment by nutrients (phosphates & nitrates)

Phosphates (phosphorus) & nitrates (nitrogen)

Block sunlight, preventing photosynthesis

Fish cannot breathe and die

$\text{CH}_4$, $\text{NH}_3$, $\text{H}_2\text{S}$, $\text{PH}_3$

Methane, Ammonia, Phosphine, Sulfide

Sulfuric acid ($\text{H}_2\text{SO}_4$), nitric ($\text{HNO}_3$)

Identify source and extent of contamination
