300

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

400

What are 4 examples of target organs? 

Lungs, liver, kidneys, and nervous system 

400

What are examples of toxins that an environmental toxicologist would investigate (mentioned in the slideshow)? 

VOCs, greenhouse gases, fossil fuels, heavy metals, pesticides, etc. 

400

Pesticides also increase _________ production in soils while releasing ___________

Nitrous Oxide, Ground-Level Ozone


500

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)

500

Give at least 3 examples of diseases caused by toxins which are mentioned in the slideshow. 

  • Asbestosis
  • Asthma
  • Bronchiolitis obliterans
  • Cancer

  • Leukemia
500

State the word equation of gold cyanidation. 

Solid Gold +Aqueous Sodium Cyanide + Oxygen Gas + Liquid Water -> Aqueous Sodium Dicyanoaurate + Aqueous Sodium Hydroxide

500

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
