Wastewater, water, air, noise, energy, risk, solid waste
3 human survival and negative aspects related
Air (lasts seconds) –> polluted air
Water (last 3 weeks) –> waste/polluted water
Food (last 2 months) –> contaminated soil
1996
National Research Council Study (NRC)
1987
World Commission on Environment and Development (WCED)
Calculation of mass accumulation
Total Mass flow in = total mass flow out + rate of mass storage
Types of wastes
Municipal, Hazardous, Biomedical
Properties of hazardous waste
Toxicity, reactivity, ignitability, corrosiveness (TRIC)
Emerging contaminants
PFAS: Perfluoroalkyl and Polyfluoroalkyl Substances
–> hazardous substances that we should remove from emerging contaminants
Recent trends for energy use (emerging contaminants: carbon sequestration)
capturing and storing atmospheric CO2
→ reduce CO2 in the atmosphere to reduce global climate change
1963
Clean Air Act
6 major air pollutants
NGLPCS
Particulate matter(PM; Dust, smoke, haze)
Sulfur Dioxide (SO2)
Carbon monoxide (CO)
Nitrogen dioxide (NO2)
Ground-level ozone (O)
Lead (HEAVY METAL)
Effects of particles: 10 um
Removed in nose and throat
Effects of particles: 5 to 10 um
Removed in trachea & bronchi –> doesn’t get to lungs
Effects of particles: 0.5 to 5 um
Alveoli –> lung damage
Characteristics of NO2
Acid rain
