Monday, March 14, 2016 ENV 1301 Week 10 Notes Chapter 10: Toxicology - Occupational Safety and Health Administration - Mercury vapor — mercury is heavy metal: once it goes into an organism, it will not come out - Toxic threshold - Toxic substance: one that can have an adverse effect on an organism - Risk assessment: trying to quantify the risk associated with a particular activity - Percieved risk: based on psychology - Health Risk Categories • Age—health is best post-pubescent • Gender—sex cells are sensitive to environmental changes • Pre-existing health conditions— - Latency period: the length of time it takes for a disease to manifest itself • Genetics (genetic predisposition)— - dose—ppm…mg/L - duration • What two things determine response to a pollution: - Dose, Duration - Vector of exposure • inhalation ingestion • - Two types of risk • voluntary • involuntary 1 Monday, March 14, 2016 - Bioconcentration - Hormone disrupter: chemicals can be ingested and begin to mimic hormones - Mutation: change in genetic code • lethal • nonlethal - some chemicals can cause birth defects - Four major types of hazards: • physical - (i.e. sunburn) • chemical - something you ingest • biological - organism you ingest • cultural - hazards resulting from socioeconomic status or choices in our place of living or work - Environmental health: assesses environmental factors that influence health and quality of life\ - Morbidity - disease - Vector: and organism that transfers pathogens to a host - Environmental health hazards that exist indoors: • Radon • Lead Poisoning • Asbestos - Isotope: different number or protons and neutrons - Rachel Carson published Silent Spring in 1962 • brought together studies to show DDT risks to people, wildlife, and ecosystems • In the 1960’s, pesticides were mostly untested and were sprayed over public areas, assuming they would do no harm. - The book generated significant social change - Types of toxicants based on health effects: 2 Monday, March 14, 2016 • Carcinogens • Mutagens • Teratogens • Neurotoxins • Allergens • Endocrine disruptors - Endocrine disruption research is controversial • BPA • Lethal Dose - Precursor: breakdown products: toxicants degrade into simpler products • some of the precursors may be more or less harmful than the original substance and stay in the body for longer than the actual chemical - Bioaccumulation: toxicants build up in animal tissues as the trophic levels increase - Biomagnification: toxicants concentrate in top predators • near extinction of peregrine falcons, bald eagles, and brown pelicans - Linear dose response curve: • dose-response analysis: measures how much effect a toxicant produces - Two types of exposure: • Acute: high exposure for short periods of time to a hazard - stem from discreet events (oil spills, nuclear accident, ingestion) • Chronic exposure: low exposure for long periods of time to a hazard - more common but harder to detect affects organs gradually: (lung cancer, luver damage) • 3 Wednesday, March 23, 2016 ENV 1301 Week 11 Notes continued Water - Water Quality • Types of Water - ground - surface • Water cycle (4 steps) - Precipitation • latent heat of evaporation - Surface water runoff - Ground water storage - Evapo-Transpiration (Evaporation, Transpiration; ET): water loss through phase change • Water Pollution - point & non point • Water Quality - N - P - Temp - DO - BOD - COD - biologicals (will discuss) Water Shed: geographical area within which water flows after a major storm event 1 Wednesday, March 23, 2016 Estuary: where fresh water meets salt water Productive: the amount of energy that can be fixed per unit area per unit time (more carbon fixed in an estuary than anywhere else) Phase change: liquid water turns into gas Relative Humidity: percentage of water vapor that the air can hold Surface water/ surface runoff Porosity: Ground water: water that is stored in the pores of the soil Transpiration: unbroken pathway from the ground all the way to the atmosphere through the stomates of the leaves/plants; at the same time CO2 Spring: where groundwater meets the surface 2
