Water chemicals + pollutants effects Flashcards
Water testing Eutrophication
INDICATOR SPECIES
Plants and animals that show something about the environment by their** presence, absence, or abundance.**
Ex. Frogs: Frog skin is permmeable so they absorb pollutants easliy
Biotic Index
Scale of 1-10 that gives a measure of quality of an ecosystem by looking at the presence or abundance of the species living there
Invertebrates are used to know pollution levels bc they are senstive to Decreased oxygen
Eutrophication
Step 1
Urband or Agriclutural land runoff that contains high nutrient levels meet a water body
Eutrophication
Step 2
Excess nutrients causes plants to grow faster and algae bloom happens on surface
Eutrophication
Step 3
Sunlight block
DO levels decrease
zooplankton accumulate to feast on algae
Eutrophication
Step 4
Algae dies off so decomposers take over; BOD increase while DO decreases
Eutrophication
Step 5
DO is so low that a dead zone is created; food chain dies and orgainsms die
Ocean Water Accumlation
Litter that ends up in ocean and accumlates in ocean b/c water circulation & convection currents
Causes- decrease tourism, chocking hazzard to animals, and toxins into water
Great Pacific Garbage Patch
Ocean Warming
Ocean heat up leading caued by GHGs in atmosphere trapping more energy from the sun
- Stronger stormes
- Heat loss
- Coral bleaching
Heavy Metal Solubility
Mehals can dissove meaving toxic metals in ocean
