This document discusses different types of personal pollution including food additives, smoking, medicine, alcohol, drugs, cosmetics and their effects. It provides details on common food additives like artificial sweeteners and food colors and their potential health risks. The document also examines smoking and its delivery of nicotine to the brain. Medicines, alcohol, and dangerous drugs are discussed in terms of their appropriate versus inappropriate usage. Finally, the document outlines common toxic ingredients to avoid in cosmetics like parabens, phthalates, and sodium lauryl sulfate due to potential links to health issues.

1. PERSONAL POLLUTION
Natural Science 1
By: Francis Gladys Belmin

2. What is Personal Pollution?
• a kind of pollution that human produce
and create
• the pollution of the human body and
lifestyle with harmful actions
• it is something that someone do
voluntarily (and involuntarily depending
on the habit) yet sometimes it is
something that humans received from
those around them.

3. Types of Pollution
• Food Additives
• Smoking
• Medicine
• Alcohol
• Dangerous Drugs and Narcotics
• Cosmetics

4. Food Additives
• a substance added to food to
improve its flavor, color, texture,
or resistance to spoilage
• enhances the shelf-life of food
products and makes food
attractive to customers

5. Kinds of Food Additives
1. Intentional – substances added
on purpose to perform specific
functions. Example: salt
2. Incidental/accidental –
substances which become part
of a food product through some
phase of production, processing,
storage or packaging.

6. Kinds of Food Additives
3. Natural - substances derived
from natural sources such as
annato, chlorophyll and carotene
food colors
4. Artificial – substances that are
produced synthetically such as
saccharin and cyclamate sweetener

8. Some additives are carcinogenic or
cancer- causing agent
Sodium nitrite is used for curing bacon and other
meat products is considered carcinogenic. It can
affect the hemoglobin by impairing its oxygen-
carrying capacity.
Sulfites when present in high
concentrations can cause
asthmatic attacks and may cause
gastric irritation
• Artificial sweetener like cyclamate can cause liver cancer while
saccharin is shown to be a carcinogen
• 90% of food colors today are synthetic and which are found to be
carcinogenic and may cause allergic reactions for adult and
hyperactivity for children like tartrazine
• MSG is safe to use as flavor enhancer in food in moderate
amount however too much of it may cause nausea, headache,
vomiting and dizziness

9. • Heavy metals like lead, mercury or cadmium are
reported to be present in the food we eat.
• Lead decreases RBC and affects the nervous system
particularly the brain which can be found in milk
• Fishes may contain mercury or cadmium (ex.
Minamata disease and itai-itai disease can lead to
death

10. MEDICINE
• A substance used to treat a disease
• Can have undesirable effects if taken
in too large quantities
– Self-practice and self-medication may lead
to misuse and overuse of medicines

12. Dangerous Drugs
and Narcotics
• Drugs are needed to
prevent or cure diseases
• Drugs may be:
1. Regulated – those which can be taken by a
patient under the administration of a physician.
The dosage required is just enough to produce
the particular effect needed
2. Restricted – may produce harmful effect or
might even kill a person when taken in large
amount.

15. SMOKING
Smoking is the inhalation of the smoke of burning tobacco that
is used mostly in three forms: cigarettes, pipes, and cigars.
Casual smoking is the act of smoking only occasionally,
usually in a social situation or to relieve stress. A smoking
habit is a physical addiction to tobacco products.
Nicotine, the active ingredient in tobacco, is inhaled into the
lungs, where most of it stays. The rest passes into the
bloodstream, reaching the brain in about 10 seconds and
dispersing throughout the body in about 20 seconds.

16. Nicotine is
an alkaloid
found in the
nightshade
family of
plants
(Solanaceae)
that functions
as an
antiherbivore
chemical with
particular
specificity to
insects (it
was widely
used as an
insecticide in
the past)

19. Alcohol
Alcohol (ethanol or ethyl alcohol) is the ingredient found
in beer, wine and spirits that causes drunkenness.
According to the World Health Organization (WHO),
globally, 3.3 milliondeaths every year result from the
harmful use of alcohol.
Alcoholism or Alcohol Use Disorder (AUD) is a
condition in which a person has a desire or physical need
to consume alcohol, even though it has a negative impact
on their life.

20. • A person with AUD or formerly
called alcoholic does not know
when or how to stop drinking.
They spend a lot of time thinking
about alcohol, and they cannot
control how much they consume,
even if it is causing serious
problems at home, work, and
financially.

21. • Some signs and symptoms of AUD:
o drinking alone or in secret
o having rituals and being irritated if someone else
comments on these rituals, for example, drinks
before, during, or after meals, or after work
o losing interest in hobbies that were previously
enjoyed
o feeling irritable when drinking times approach,
especially if alcohol is not, or may not be, available
o storing alcohol in unlikely places
o having problems with relationships, the law,
finances, or work that stem from drinking
o needing more alcohol to feel its effect
o experiencing nausea, sweating, or shaking
when not drinking
The problems linked to alcohol dependence are extensive.
The effects can be physical, psychological, and social.

22. Alcohol is classed as a ‘sedative hypnotic’ drug, which means
it acts to depress the central nervous system at high doses. At
lower doses, alcohol can act as a stimulant, inducing feelings
of euphoria and talkativeness, but drinking too much alcohol at
one session can lead to drowsiness, respiratory depression
(where breathing becomes slow, shallow or stops entirely),
coma or even death.
Long Term
effect of
Alcohol:
Cirrhosis
(shrunken
liver,
fibrous
and
ceases to
function)

23. Cosmetics
Cosmetics are products used
on body to clean it, beautify it, or
change how it looks.
Examples are makeup, hair
dyes, perfumes, skin-care
creams.

24. • Cosmetics can cause allergic reactions.
• Fragrances and preservatives are the most common
causes of skin problems.
Manufacturers are required to list the ingredients of the product.
Labels such as "natural" and "hypoallergenic" have no official
meaning. Companies can use them to mean whatever they want.

25. Toxic Ingredients to Avoid
Parabens are a whole family of chemicals
(methylparabens, propylparabens, butylparabens,
and ethylparabens) that help preserve shelf-life of
products.
• Parabens can mimic estrogen in the body
disrupting the hormonal balance that can
lead to reproductive and fertility issues
• Linked to breast cancer
• Can be found in face cleanser, body wash,
body lotion, foundation and shampoo
Phthalates are group of chemicals used to soften and
increase the flexibility of plastics in cosmetics. This
helps products stick to our skin.
• Extremely dangerous to children, but it’s best
to avoid them all together as they can be
serious endocrine disruptors and even cause
birth defects.
• Mostly found in deodorant, lotion, fragrance
& hair spray

26. Toxic Ingredients to Avoid
Fragrance doesn’t sound scary, but “fragrance” is
considered a trade secret which means that
companies don’t have to disclose what ingredients
are inside. Often, the ingredients include tons of
chemicals that can cause allergies, hormone
disruption and lead to bigger health problems
reproductive issues and infertility.
• Mostly found in moisturizers, hand creams and
hair products
Sodium Lauryl Sulfate (SLS) and/or Sodium
Laureth Sulfate (SLES)
SLS and SLES are known to cause skin
irritation and trigger different allergies.
• Commonly found in shampoo, body wash,
bubble bath

27. Toxic Ingredients to Avoid
BHA & BHT are synthetic antioxidants
that are used to extend shelf life and
are likely carcinogens and hormone
disruptors that may cause liver
damage.
• lipsticks, moisturizers, diaper
creams, and other cosmetics
Retinyl palmitate and Retinol (aka, Vitamin A)
It help soften wrinkles but it may damage
DNA and speed the growth of skin tumors
when used on your skin
• moisturizer, anti-aging skincare

28. Toxic Ingredients to Avoid
Lead is a heavy metal and is a
neurotoxin. It can cause serious
behavioral and learning problems, like
lowered IQ. It’s already been removed
from things like paint and gasoline.
• found in lipstick and lip gloss
Formaldehyde is used to
preserve dead animals and was
used in some cosmetics.
• It is a known carcinogen
that is also linked to asthma,
neurotoxicity, and
developmental toxicity.
• shampoo, body wash,
bubble bath
