Biology, chemistry, and epidemiolgy
How do toxins enter the body through ingestion?
Toxins (spilled or settled in food, beverages, cigarettes, beards, hands, etc.) can travel into the body through ingestion
Key word: swallowing
What is the reaction that is known to occur during gold cyanidation?
Oxidization
What are two greenhouse gases released from eutrophication and nutrient buildup?
Nitrous Oxide, Methane
Relationship between chemicals in the air (air pollution, the environment, living organisms, and human health.
What are 4 examples of target organs?
Lungs, liver, kidneys, and nervous system
What are examples of toxins that an environmental toxicologist would investigate (mentioned in the slideshow)?
VOCs, greenhouse gases, fossil fuels, heavy metals, pesticides, etc.
Pesticides also increase _________ production in soils while releasing ___________
Nitrous Oxide, Ground-Level Ozone
What is environmental toxicology concerned with?
The movement of chemicals throughout the environment (learning where they go, how they get there, and how they can enter humans and harm us)
Give at least 3 examples of diseases caused by toxins which are mentioned in the slideshow.
State the word equation of gold cyanidation.
Solid Gold +Aqueous Sodium Cyanide + Oxygen Gas + Liquid Water -> Aqueous Sodium Dicyanoaurate + Aqueous Sodium Hydroxide
How do VOCs contribute to climate change?
They can react with sunlight to create tropospheric “ground-level” ozone, a greenhouse gas, which heavily contributes to climate change after CO2 and methane
