A HAIR RAISING DILEMMA
ORGANIC
CONTAINS CARBON
INORGANIC
REFERRED TO AS MINERALS
NUTRIENTS
TWO TYPES
MACROMINERAL
100mg/DAY OR MORE
CARBOHYDRATES
GIVES YOU ENERGY
SOURCES: RICE GRAINS, POTATOES AND FRUITS.
PROTIENS
HELP BULID AND REPAIR MUSCLE TISSUES
SOURCES: MEAT, EGGS, DAIRY PRODUCTS, LEGUMES, NUTS
LIPIDS (FATS)
STORES UNUSED ENERGY
SOURCES: VEGETABLE OIL, NUT OILS, SOME DAIRY
TRACE ELEMENT
LESS THAN 100mg/DAY
NITROGEN
LEAF GROWTH
FERTILIZER
CONTAINS 3 ELEMENTS
N/P/K
PHOSPHOROUS
FLOWER GROWTH
POTASSIUM
ROOT AND STEM GROWTH
DDT
Toxin used to kill bugs, but had larger effects on large birds or pray through biomagnification
Litmus Paper
an indicator paper that turns red in an acid and blue in a base
pH PAPER
pH paper is used to test the acidic levels in liquids, water would be considered neutral so color changes would occur in the middle of the color wheel
Scrubbers
technology to chemically treat gases produced in combustion to remove hazardous components and neutralize acidic gases
NEUTRALS
7 on the pH scale
BASES
8-14 on pH scale,
turns litmus paper
blue
Neutralization
When an acid reacts with a base, the properties of each are neutralized and the products are water and a salt.
Catalytic Converters
Devices installed in the exhaust stream of cars to reduce emissions.
Acid Precipitation
Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur, nitrogen and carbon) combine with water
LIMING
Neutralization of acidic lakes with calcium carbonate
MEASURED BY
MEASURED BY
pH Scale
Power of Hydrogen
ACIDS
Has between 0-6 on the pH scale, turns litmus paper red
INSECTICIDES
CONTROLS INSECTS
BIOMAGNIFICATION
accumulation of toxins in the tissues of organisms as you move up the food chain
FUNGICIDES
CONTROLS FUNGUS
RESISTANCE
WHEN PESTICIDES ARE OVER USED ORGANISMS BECOME RESISTANCE OF THAT CHEMICAL AND IT NO LOGER AFFECTS THEM
Pesticides
Any one of these various substances is used to kill "pests"
HERBICIDES
CONTROLS WEEDS
Acute Toxicity
Serious symptoms occur after only one exposure
ex. carbon monoxide
Chronic Toxicity
Serious symptoms occur after multiple exposures
ex. mercury poisoning, radiation
Biological Indicators
Species whose health reflects the health of its ecosystem
Non-point Source
A widely spread source of pollution, such as road runoff, that is difficult to link to a specific point of origin
Bioremediation
The use of living organisms to detoxify and restore polluted and degraded ecosystems
Sanitary Landfill
A place to deposit solid waste, where a layer of earth is bulldozed over garbage each day to reduce emissions of gases and odors from the decaying trash, to minimize fires, and to discourage vermin.
Secure Landfill
A landfill designed to hold hazardous material so it cannot contaminate and cause environmental problems
POLLUTANTS
substance or energy put into the environment that has unwanted effects
Toxicity
There are two types of toxicity, the toxicity is how toxic a substance or material is.
Lethal Dose 50
The amount of a chemical that kills 50% of the test population, also referred to as LD50
Point Source
A specific source of pollution that can be identified, such as a pipe or smoke stack.
Biodegradable
Capable of being readily decomposed into harmless substances by microorganisms
