Study Notes
Environmental Engineering
- Integrates environmental science with human needs.
- Uses math and science to utilize matter and energy sources.
- Addresses sustainable development, environmental equity, habitat loss, and biodiversity.
Environmental Engineer's Role
- Possesses a deeper understanding of engineering's environmental impact than traditionally trained engineers.
- Can identify, design, and implement control strategies and technologies.
- Understands the feasibility of control and waste minimization technologies better than environmental scientists.
- Acts as a bridge between environmental scientists (ecosystem focus) and industry engineers (development focus).
- Applies engineering science to analyze environmental processes, effects, and design control systems to minimize adverse effects.
Environmental Systems Overview
- Utilizes a systems approach to understand interrelated parts and their effects.
- Includes water resource, air resource, solid waste management, and multimedia systems.
Water Resource Management System
- Water sources (surface and groundwater) determine collection, purification, transmission, and distribution.
- Surface water sources include streams, lakes, and rivers.
- Groundwater sources are pumped from wells.
- Desalination plants operate in over 120 countries.
Sustainability and Life Cycle Thinking
- Three pillars of sustainability: society, economy, and environment.
- Aims for prosperity and high quality of life without harming the environment or communities.
- Maintains sufficient natural resources for current and future generations.
- Life cycle thinking considers environmental impact from raw material acquisition to end-of-life management (recycling, remanufacturing, reuse).
- Life Cycle Assessment (LCA) quantifies trade-offs across environmental and human health endpoints.
- LCA helps identify areas for improvement and innovation.
- Benefits of LCA include increased market share, reduced environmental impact, minimized harm to human health, and improved quality of life.
Ecology and Ecosystems
- Hierarchical levels of organization: individual, population, community, ecosystem, biosphere.
- Organismal ecology focuses on individual organism's responses to the environment.
- Population ecology studies population growth and change over time.
- Community ecology examines interactions between populations of different species.
- Biomes are large-scale communities characterized by distinctive vegetation and climate.
- Ecosystem ecology studies energy flow and nutrient cycling within and between organisms and the environment.
- Human activities impacting ecosystems: species destruction, habitat loss, introduction of non-native species, excessive hunting.
Ecosystem Components
- Energy flow is essential for ecosystems.
- Primary producers: photoautotrophs (sunlight-using, inorganic carbon), photoheterotrophs (sunlight-using, organic carbon), and chemotrophs (energy from organic/inorganic carbon).
- Primary consumers: herbivores (chemoheterotrophs) and decomposers (chemoautotrophs).
- Secondary consumers: carnivores (chemoheterotrophs).
- Net primary productivity (NPP): rate of biomass production by primary producers.
- Aerobic respiration: breakdown of organic chemicals using oxygen to produce carbon dioxide.
Bioaccumulation and Biomagnification
- Bioaccumulation: accumulation of chemicals in an organism's fat tissue.
- Biomagnification: accumulation of chemicals at higher levels in organisms than in their food, potentially causing harm.
Biogeochemical Cycles
- Essential elements: carbon, nitrogen, phosphorus, sulfur, oxygen, hydrogen.
- Carbon, nitrogen, phosphorus, and sulfur are limited and cycled through the environment.
- Cycles are conserved and recycled indefinitely.
