Synthetic chemicals- compounds that are formed through a chemical process and are ubiquitous
in our everyday lives (Our knowledge has changed over time)
Types of Synthetic Chemicals
Chemicals in Commerce 100,000
Industrial Chemicals 72,000
Pesticides 600
Food Additives 8,700
Cosmetic Ingredients 7,500
Human Pharmaceuticals 3,300
New Chemicals Introduced per year 2,000
Toxicants- toxic agents introduced into the environment
1. Carcinogens- cancer causing
2. Mingens- cause mutations of DNA
3. Teratogens- affect development of who the fuck knows cause he skipped passed the slide
Endocrine Disruptors- Mimic the structure of hormone molecules
-Ex: Bisphenol A, Atrazine
Neurotoxin- a poison that attacks the nervous system
-EX: Lead
●Food webs can be plagued by the process of bioaccumulation and biomagnification
-EX: PCB’s, DDT, Mercury
●Toxicants have far reaching effects that scope globally (Table 14.1)
●Pharmaceuticals, Hormones, and other Organic Wastewater Contaminants in U.S.
Streams, 1999-2000 (reading)
-Found an overwhelming amount of chemicals from humans in the Iowa River
●Movie: “Big River”

Document Summary
Synthetic chemicals- compounds that are formed through a chemical process and are ubiquitous in our everyday lives (our knowledge has changed over time) Toxicants- toxic agents introduced into the environment: carcinogens- cancer causing, mingens- cause mutations of dna, teratogens- affect development of who the fuck knows cause he skipped passed the slide. Endocrine disruptors- mimic the structure of hormone molecules. Neurotoxin- a poison that attacks the nervous system. Food webs can be plagued by the process of bioaccumulation and biomagnification. Toxicants have far reaching effects that scope globally (table 14. 1) Pharmaceuticals, hormones, and other organic wastewater contaminants in u. s. Found an overwhelming amount of chemicals from humans in the iowa river.
