Water Quality
What is water quality
A measure of water's health and cleanliness, assessed by its physical, chemical, and biological characteristics, to determine if it's suitable for specific uses, such as drinking, recreation, or supporting aquatic life
what is the primary measurement of air quality
particulate matter 2.5 (PM2.5)
Define vector borne diseases
Diseases transmitted by vectors
Define occupational health hazard
"Any workplace condition that causes risk to an employee’s health"
the federal regulatory agency for environmental issues
Environmental Protection Agency (EPA)
Common outdoor pollutants
Industrial Waste
Fertilizers (nutrients, nitrogen, phosphorous)
E. Coli
Oil
List the six criteria pollutants
Particulate matter (PM2.5, PM10); Ground-level ozone (O₃); Carbon monoxide (CO); Sulfur dioxide (SO₂); Nitrogen oxides (NOₓ); Lead (Pb)
List the three major vectors
mosquitos; ticks; fleas
List the five types of hazards
a course or principle of action adopted or proposed by a government, party, business, or individual.
policy
Chlorine
Metals (Lead, Copper)
Bacteria
pH
Toxins
Organic Material
environmental impacts of air pollution
acid rain; chemical bioaccumulation in the food chain, ozone depletion, reduced visibility, and photosynthetic capacity
List a major disease/illness from the three major vectors
mosquitoes: dengue, yellow fever, malaria, zika, west nile, chikungunya
ticks: lyme disease, Ehrlichiosis, Rocky Mountain spotted fever
fleas: plague, typhus,
An example of how workplace hazards can become community health hazards
Disease spread, infection spread, loss of familial income, or redirected psychosocial abuse
a non-legally binding document that provides general instructions, recommendations, or interpretations to help achieve policy or legal objectives, and outline best practices
Define Point source vs Non-point source
Pollution coming from a single point/can identify the direct source of pollution vs pollution that we cant identify the direct source
Examples of the 4 types of pollution emissions
mobile: any form of transportation (car, plane, train, boat
natural: wildfire, volcanoes
area: agriculture
source: factory
What are the four environmental determinants of vector-borne diseases
climate change; land use change; global trade and travel; urbanization and housing quality
list a career and its associated work hazard/ health impact
farm workers & heat stress; first responders & respiratory health; office workers & ergonomic health; factory workers and excessive noise
rules created by governmental authorities (at federal, state, or local levels) on private individuals, businesses, and other organizations to control or govern conduct, implement laws, and serve public interests like safety, economic stability, and environmental protection.
"Regulation"
Three categories of water borne illnesses and an example of each
bacterial: cholera, typhoid, dysentery, ecoli, salmonella
viral: Hepatitis A; Rotavirus; Norovirus; Adenovirus
parasite:giardi; Cryptosporidiosis; Amebiasis.
a stationary source or group of stationary sources that emit or have the potential to emit 10 tons per year or more of a hazardous air pollutant or 25 tons per year or more of a combination of hazardous air pollutants.
"major source"
What solutions have been proposed for mosquito control, and what is the ethical dilemma around it?
Solutions: releasing GMO mosquitoes, targeting the elimination of specific mosquito species
Ethical dilemma: how do we impact the food chain by releasing GMO organisms or eliminating specific species?
What protects workers? When was it created, and what did it do?
Occupational Safety & Health Act (OSHA) of 1970 was created to “assure safe and healthful working conditions"
What are the major acts controlling air (1955 & 1970), water (1972 & 74), funding, and policies (1970)
Air Pollution Control Act - 1955
Clean Air Act - 1970
Clean Water Act - 1972
Safe Drinking Water Act - 1974
NEPA - 1970
