Transcript of Agricultural Chemistry

Organic chemistry is branch of chemistry that deals with essential atoms of life such as carbon, hydrogen, nitrogen, etc.
Organic Chemistry
Agricultural Chemistry
The modern world is dependent on hydrocarbons.
From pharmaceuticals to plastics, to different types of fuels, organic chemistry is a part of almost every industry, including agriculture.
Why is Organic Chemistry Important?
They work in various fields: agriculture, cosmetics, food industry, research, and many more.
Some specific careers in organic chemistry: material chemists, natural products chemists, and bio organic chemists.
Ex: Organic chemists can produce plastics or polymers, compounds in fragrances and makeup, synthetic chemicals, and additives.
Organic Chemists
The salary of someone going into organic chemistry depends on his or her level of education and the field of organic chemistry
Salaries can range from $45,000-$85,000
It is a science that deals with the production of food (such as fruits and vegetables) and fibers (such as cotton and linen).
Agricultural Chemistry
What do they do?
Start research projects to find agricultural products and test the effect of compounds on the environment and food
Where can they work?
Chemical companies, colleges and universities, food companies, government agencies (USDA, FDA), and research firms
Salary: 35,000-70,000 depending on education level
How does their work affect you?
The fertilizers and pesticides that agricultural chemists formulate can result in consumers’ choice of eating organic vs. non-organic foods

Agricultural Chemists
Control diseases, pests, and weeds in crops.
Creates a large mass of crops (increase profit for corporations and farmers and better economy)
Help make food fit for consumption ( better quality)
Increase in production leads to lower prices and wider selection;thus, more accessibility to these fresh foods gives people the opportunity to have a healthier diet
Protect overall human health by removing fungi on crops; therefore, preventing consumer sickness

Why Pesticides Are Beneficial (Pros)
According to Princeton University, 60% of herbicides, 90% of fungicides and 30% of insecticides are carcinogens-a startling number and main reason why organic foods are becoming more and more popular.
By producing more organic food, people can help clean up the environment and prevent the spread of more pesticides.
The general consensus is that pesticides created by agricultural chemists are not healthy for people and the environment.
Expert Opinion
Organic chemistry is mostly taken in sophomore and junior year of college
Majors that take organic chemistry: chemistry, biochemistry, biomedical engineering, chemical engineering, nursing, pre-med, pre-pharmacology, and other medical majors
Students studying organic chemistry focus on carbon containing compounds and functional groups such as alkanes, alkenes, alkynes, aromatics, alcohols, amines, carboxylic acid, ketones, amides, ethers, and esters.
Education- Organic Chemistry
• A current focus in organic chemistry is to calculate the Global Warming Potential (GWP) based on the amount of emitted greenhouse gases (GHGs)
• Researchers found an increase of 69.3% GWP of methane and nitrous oxide over a span of thirty years (using simulation models)
• They plan to decrease GHG emission (increase nitrogen use in crops, and reduce carbon usage during rice season)
• A total decrease of 66% of GHG emission could be achieved nationally.

Current Research
Net Greenhouse Gas Balance in China’s Croplands over the Last Three Decades and Its Mitigation Potential
The Cons of Pesticides
extremely harmful to both the human body and the environment
over 865 EPA registered pesticides in the world
-it’s very probable that everyone in this room has ingested a pesticide
can cause health problems that include birth defects and nerve damage

Organophosphate-a commercial fruit and vegetable pesticide
-can cause ADHD in children exposed to the chemical
-can affect the nervous system, causing excessive salivation, stomach pain, vomiting, constipation and diarrhea

Pesticides-contaminate soil, water, turf and other forms of vegetation
Pesticide contamination affects entire ecosystems (hurting birds, fish, beneficial insects and non-target plants)
How are people combating the pesticide problem?
The answer is organic foods.
farmers use natural fertilizers and pesticides made from plant and animal compounds.
organic farmers use historical methods -crop rotation, tilling, or hand weeding
How is food determined to be organic?
The USDA is the regulation board
100% Organic means products are completely organic or made of all organic ingredients
Organic means 95% of the product is organic
