Resources/Waste: Home Chemicals Introduction Chemical Connec

Chemicals are everywhere, in the air you breathe, in the food you eat, and in the chair you’re sitting on. Moreover, you’re mostly chemicals. Ninety nine percent of the human body is composed of just 6 chemical elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. After you die, you’ll decompose into hydrogen, nitrogen, water, ammonia, carbon dioxide, phosphoric acid, and sulfuric acid. So, from chemicals we come and to chemicals we go.

Chemical elements are substances that contain one kind of atom and cannot be separated into simpler substances. There are 116 known chemical elements, of which 91 occur naturally. The other 25 are man-made. These elements are listed in the periodic table.

Chemical compounds are formed by the combination of two or more elements. The one you’re probably most familiar with is H2O, two parts hydrogen and one part oxygen, also known as water. Other common compounds include sodium chloride (NaCl) or salt, glucose (C12H22O11) or sugar, and CH3COOC6H4COOH or aspirin. Chemicals are used in a wide range of industrial and commercial applications including plastics, adhesives, absorbents, fertilizers, detergents, dyes, explosives, oils, inks, lubricants, metals, paper, insecticides, pharmaceuticals, solvents, waxes, photography, food additives and on and on. So, you see, chemicals are everywhere.

There are several ways to classify chemicals. Organic chemicals are those chemicals that contain the element carbon, C. Organic chemicals can be broken down by micro-organisms and reactions with other chemicals, as well as photochemically by ultraviolet or visible light. The rate at which a chemical degrades is expressed as half-life, the amount of time it takes for half of the chemical to be converted into some other chemical or element. Generally, organic chemicals biodegrade or decompose more rapidly than inorganic chemicals, which do not contain carbon. Inorganic chemicals include salt, asbestos, and silicates as well as minerals such as iron, aluminum, and phosphorus, among others. Chemicals can also be either natural or synthetic. Natural chemicals are those which are found occurring in the environment which are not introduced by humans. Synthetic chemicals are those which are developed by humans and do not exist in nature. It might be easy to assume that natural, organic chemicals are less harmful to humans. This is not the case as many poisons come from plants and animals.

This exercise involves conducting an inventory of the types of chemicals in your home. Identify one product that you use for each of the categories on the Activity Sheet. If you do not use a particular category of product, simply enter the phrase "do not use" and explain why.

For each product identified that you do use indicate the following: 1. The product name 2. What the product does, also known as the product “service” 3. Whether there is some type of warning about using the product. 4. What the warning says. After doing this, select three products from your household product list which you think may be “hazardous” based on the warnings listed on the products. The U.S. Environmental Protection Agency defines hazardous as any material that is ignitable, corrosive, explosive, or toxic to humans, plants or animals.

The Consumer Products Information Database (CPID) maintains a database that contains a wide variety of information on over 21,000 consumer products. Information contained in the database includes the chemical ingredients, the manufacturer and contact information, as well as any possible acute and chronic effects associated with the chemicals that make up the products.

Answer the questions on the Activity Sheet after you have completed your inventory. At the conclusion of this step in the exercise, you should have looked up and found results for 3 products.

Paper For Above Instructions

In today's world, household chemicals are ubiquitous, found in nearly every product we use daily. Understanding these chemicals can help us navigate their potential hazards and make informed decisions about their use. In this exercise, I will identify and assess various household products, focusing on their components and associated warnings.

Household Chemical Inventory

For the inventory, I selected several categories of household products. The following is a summary of the products I have identified and assessed:

  • Auto Products: Motor Oil - Used for lubricating the engine; Warning: Yes - Avoid prolonged skin contact.
  • Pesticides: Raid Ant and Roach Killer - Kills ants and roaches; Warning: Yes - Harmful if inhaled.
  • Personal Care: Neutrogena Shampoo - Cleans hair; Warning: No.
  • Arts & Crafts: Elmer’s School Glue - Used for crafts; Warning: No.
  • Inside the Home: Clorox Bleach - Disinfects surfaces; Warning: Yes - Corrosive; avoid contact with skin.
  • Landscape & Yard: Roundup - Kills weeds; Warning: Yes - Toxic to aquatic life.
  • Home Maintenance: WD-40 - Lubricates locks; Warning: Yes - Flammable, do not spray near heat sources.
  • Pet Care: Do not use - No pets in the household.

Assessment of Hazardous Products

From the products identified, I chose to focus on three potentially hazardous items based on their warnings: Motor Oil, Raid Ant and Roach Killer, and Clorox Bleach.

  1. Motor Oil: This product can be hazardous due to its ability to irritate the skin upon contact and contribute to environmental pollution if disposed of improperly.
  2. Raid Ant and Roach Killer: This insecticide is potentially harmful due to its toxicity when inhaled and can pose serious risks to health.
  3. Clorox Bleach: Known for its disinfecting properties, bleach is dangerous as it is corrosive and can cause severe burns if it comes into contact with skin.

The next step was to research these products using the Consumer Products Information Database to better understand their hazardous nature.

Research Findings

Upon researching motor oil, the Safety Data Sheet (SDS) indicated that it has a health hazard rating of 2, which means it can cause temporary injury with sustained exposure. The flammability rating is 1, indicating it must be heated before ignition can occur. Additionally, the reactivity rating is 0, suggesting it is stable under normal conditions. Acute health effects include skin irritation and potential lung damage if inhaled, while chronic effects include long-term skin exposure leading to dermatitis.

For the Raid Ant and Roach Killer, the SDS showed a health hazard rating of 3, indicating it can cause serious injury. It has a flammability rating of 2, meaning it can ignite under high heat. The reactivity rating is 1, which means it can react during high heat. Acute effects may include respiratory issues, and chronic exposure could result in neurological damage.

Finally, Clorox Bleach's SDS revealed a health hazard rating of 3 with a flammability rating of 0, indicating minimal risk. Its reactivity rating is also 0. However, acute effects can include serious respiratory distress, and chronic exposures might lead to lung damage over time.

Hazard Ranking

When ranking the products based on their hazardous nature, I concluded:

  1. Raid Ant and Roach Killer - Most hazardous due to high toxicity and potential for serious health impacts.
  2. Clorox Bleach - Highly corrosive and serious acute health effects.
  3. Motor Oil - Moderate risk, mainly environmental concerns and skin irritation.

Conclusion

Through this exercise, I learned that many common household products contain potentially dangerous chemicals. The information provided by the Consumer Products Information Database was comprehensive and crucial in understanding the products I use daily. Awareness of the potential risks associated with these chemicals can promote safer usage and disposal practices in our homes.
