Study Notes

UV Index and Sun Protection

UV Index reading of 11 or more means extreme risk of harm from unprotected sun exposure.
UV Index reading of 8-10 means very high risk of harm from unprotected sun exposure.
UV Index reading of 6-7 means high risk of harm from unprotected sun exposure.
UV Index reading of 3-5 means moderate risk of harm from unprotected sun exposure.
UV Index reading of 0-2 means low danger from the sun's UV rays for the average person.
Bright surfaces like sand, water, and snow reflect UV and increase exposure.
Reduce time in the sun between 10 a.m. and 4 p.m.
Seek shade and wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.

Water Pollutants

Biological Pollutants

Viruses: poliomyelitis virus, hepatitis A
Bacteria: Escherichia coli, Legionella spp, Shigella spp, Vibrio cholera
Parasites: Entamoeba histolytica, Giardia lamblia

Non-biological Pollutants

Inorganic chemicals: lead, copper, arsenic
Industrial solvents: trichloroethylene (TCE)
Pesticides: dichlorodiphenyltrichloroethane (DDT), atrazine

Radiation

Radiation is the process in which energy is emitted as particles or waves.
Sources of natural radiation: extraterrestrial (outer space and the Sun) or terrestrial (radioactive minerals emanating from the Earth).
The sun is a considerable source of radiation, including visible light, heat, and ultraviolet (UV) radiation.
