health effects classified as (3)

1)Acute
2) Chronic
3)carcinogen

2

CAA

Clean Air act

3

EPA

Environmental Protection Agency

4

NAAQS

National Ambient Air Quality Standards

5

SIPs

State Implementation Plans

6

List Air Pollutants

1) PM- mixture small liquid or solid particles in air
2)Sulfur Dioxide (S02)- released from combustion of coal MAY UNDERGO CHEMICAL REACTION CAUSING ACID RAIN
3)Carbon Monoxide- Fossil fuel burned
4) NO2- From fuel combustion- at hight temperature NO oxidizes and forms NO2
5)OZONE O3- transportation sector main source- oxidant- smog
6)Lead- Bioaccumulation... from smelting

7

HAPs

Hazardous air pollutants

8

MACT

Maximum Available control technology

9

TRI

toxic release inventory

10

What is stratospheric ozone depletion

stratosphere absorbs UV-B rays, but as halocarbons are emitted to the atmosphere, they reduce the amount of ozone and more UV-B pass

11

Explain Greenhouse gases

solar energy from sin at short wavelengths that are partially absorbed by earth's surface. warmed surfaces radiate energy back and this energy gets trapped in the atmosphere at longer wavelengths. the balance of this phenomenon determines temperature

12

avg. temperature on earth

15

13

GWP

Global warming potential

14

Main Greenhouse gases

CO2- 85%
CH4- 10%
halocarbons, N20 (laughing gas), O3 (ozone)

15

Major Water contaminants (9)

1)Pathogens - bacteria, viruses
2) Organic Waste- Human waste & animal excrement...
3)Nutrients- Nitrogen & Phosphorus used in fertilizers and detergents increase quantity algae.... Depletion of dissolved oxygen
4)Toxic Organic Chemicals - PESTICIDES, VOCs
5) Toxic Metals- lead form old pipes
6) Suspended Solids- sun cant go through and vegetation cant survive
7)acidity- biological processes impaired
8)SALTS
9)Heat- biological processes impaired at high temperature

16

TSS

Total Suspended Solids

17

TDS

Total dissolved solids

18

SWDA

SAFE WATER DRINKING ACT, established by EPA

19

MCLs

Max. contaminant levels

20

FWPCA

Federal water Pollution Control Act

21

Name the 3 Obstacles to clean groundwater

1)Petroleum
2)Nitrates From Fertilizers
3)Abandoned Chemical Waste dumps

22

Hazardous wastes are described by:

1) IGNITABILITY
2) CORROSIVITY- STRONG ACID BASES
3)REACTIVITY- STRONG REACTIONS
4)TOXICITY- ABILITY TO THREATEN WATER AND SOIL

23

TCLP

toxicity characteristic Leaching procedure

24

CERCLA

comprehensive environmental response, compensation, liability act

25

NON-HAZARDOUS WASTES

1)Trash
2)MSW- Municipal waste
3)Industrial wastes

26

AEC

Atomic Energy Commission

27

Name the 4 types of radioactive wastes

1)High lever---- MOST DANGEROUS
2) Transuranic -- HEAVIER THAN URANIUM, from weapon production
3)Low level (LLW)- 3 classes A,B,C---- C most dangerous
4)Uranium Mill tailings-- largest volume

28

What is climate??

"Average weather" over 30 year span.... determined by complex interactions of many factors

29

Heat flux

radiative energy per surface area ( FROM SUN)

30

Tropopause

Upper boundary of troposphere
