1
Indoor Air Pollution One of the most pressing global problems today
Mostly from household products 2 to 5 times – and occasionally more than 100 times – higher than outdoor pollutant levels Statistics show that nearly half of the world is affected by indoor air pollution Causes about: 35.7% of respiratory tract infections 22% of chronic obstructive pulmonary disease 1.5% of trachea, bronchus and lung cancer
2
Indoor Air Pollution Residues of more than 400 toxic chemicals have been identified in human blood and fat tissue A five-year U.S. Environmental Protection Agency (EPA) study that surveyed 600 homes showed that: Peak concentrations of 20 toxic compounds were 200 to 500 times higher inside some homes than outdoors Linked to cancer and birth defects Pesticides Risk for leukemia increases by 4 to 7 times for children, ages 10 and under Pesticides, insecticides, herbicides and flea collars on pets Increases risk of childhood brain cancer
3
Indoor Air Pollution Symptoms Runny nose Itchy eyes Scratchy throat
Headaches and dizziness Respiratory tract infections Long-term exposure to indoor air pollution Lung cancer Liver and kidney damage Central nervous system damage
4
Personal Care Products e. g
Personal Care Products e.g. Anti-bacterial Toothpaste, Hand Wash and Shower Gel Triclosan Triclosan mixed with chlorinated water releases chloroform. When absorbed through the skin, chloroform may cause depression, liver disorder and even cancer.
5
Personal Care Products e. g
Personal Care Products e.g. Anti-bacterial Toothpaste, Hand Wash and Shower Gel Sodium Lauryl Sulfate (SLS) Prolonged contact may lead to urinary tract and vaginal inflammation and infection Animal tests show: Eye damage, depression, labored breathing, diarrhea, severe skin irritation and corrosion, and even death Research shows that long-term exposure to SLS may increase cancer risk A concentration of more than 0.01% of SLS leads to cell death
6
Household Cleaning Products e. g
Household Cleaning Products e.g. Dishwashing Liquid, Washing Powder, Toilet Detergent, Tile/Glass Cleaning Liquid Formaldehyde Highly irritating Allergen Headaches, nausea, chest tightness, eye pain, palpitations, insomnia, forgetfulness Prolonged exposure during pregnancy may cause birth defects and even fetal death Animal tests show that inhaling high concentrations may lead to nasopharyngeal cancer Sustained release of 3 to 15 years
7
Dry Cleaning — Carcinogenic Tetrachloroethylene Naphthalene Benzene
Formaldehyde Trichloroethylene — Carcinogenic
8
Indoor Furnishings e.g. Carpet, Paint, Wood Lacquer
Grime and dust Tetrachloroethylene Irritating and toxic to central nervous system and respiratory system Turpentine Easily absorbed through skin Eye irritation, headache, dizziness and vomiting Breathing or swallowing it causes kidney and bladder irritation Volatile Organic Compounds Carcinogenic
9
Garden Pesticides, and Flea, Tick and Lice Inhibitors
Lindane Carcinogenic May trigger epilepsy in rare circumstances May even cause death
10
Shoe and Furniture Polish
Turpentine Easily absorbed through skin Eye irritation, headache, dizziness and vomiting Breathing or swallowing it causes kidney and bladder irritation Nitrobenzene Toxic to reproductive and central nervous systems Absorbed through skin
11
Air Fresheners Isopar p-Dichlorobenzene Methylene dichloride
A toxic substance widely used by manufacturers p-Dichlorobenzene Toxic to liver and kidneys Carcinogenic Methylene dichloride A propellant used in many aerosol products Naphthalene and Formaldehyde Carcinogens
12
Essential Oils Earliest mention in 1188
Distilled from flowers, leaves and fruit skins Aroma from natural botanical essences Calming and relaxing effects; help to boost concentration Improve blood circulation Activate cells Increase metabolism Restore balance to the body
13
How Aroma Affects the Human Body
Travels through olfactory nerve to the brain Stimulates brain to secrete endorphins and enkephalins Produces a relaxing effect Absorbed through skin Absorbed and carried by tissue fluid between cells Only a few types of essential oil e.g. mint can be absorbed through skin
14
Staying Happy and Relaxed
Helps to: Increase immunity Improve digestion Boost concentration Improve sleep quality
15
Natural Aromas Lavender—Melts away stress; soothing
Lemongrass—Lifts moods and boosts concentration Rose—Uplifting and inspires joy and happiness Jasmine—Soothing and revitalizing Green Apple—Lifts moods and enhances vitality Mint—Refreshing; prevents dizziness; cooling and relieves pain
16
Essential Oil Extraction Methods
Distillation Expression Supercritical Fluid Extraction
17
Distillation Most common essential oil extraction method
Hot steam helps to release aromatic molecules from plant material, which evaporate into the steam Passed through a condenser to separate water and essential oil Essential oil Condensed steam—Hydrosol
18
Distillation
19
Essential Oils Extracted By Distillation
Rose Jasmine Lavender Peppermint Lemongrass
20
Expression Expression—Skin, pulp or seeds
Obtains a mixture of water and oil High-speed centrifugation—Separates water and oil
21
Essential Oils Extracted By Expression
Lemon Sweet orange Tangerine Grapefruit
22
Supercritical Fluid Extraction (SFE)
One of the most advanced extraction techniques Supercritical fluid—carbon dioxide Critical Point—31.3C, 72.9 atm Superior penetration Excellent solvent Safe and non-toxic Non-flammable Non-explosive
23
Supercritical Fluid Extraction (SFE)
Effectively separates, extracts and purifies High efficacy and not easily oxidized Natural and does not cause chemical pollution
24
Supercritical Fluid Extraction (SFE)
25
Essential Oils Extracted By Supercritical Fluid Extraction
Rose 1,500 to 2,500 kilograms of roses to extract one kilogram of essential oil Lavender 200 kilograms of lavender to extract one kilogram of essential oil (Distillation)
26
