TYPES OF HAZARDS CHEMICAL - ANYTHING THAT HARMS HUMAN HEALTH BIOLOGICAL – VIRUS’, BACTERIA, OR ANY OTHER LIVING ORGANISM THAT CAUSES HARM SOCIAL – RESULT FROM WHERE WE LIVE, OUR JOB, OR LIFESTYLE CHOICES

REFRESH: CHEMICAL HAZARD: ANYTHING THAT HARMS HUMAN HEALTH CARCINOGEN – CAUSES CANCER MUTAGEN – CAUSE GENETIC CHANGES (MUTATIONS) TERATOGENS – HARM EMBRYO’S OR FETUS’ NEUROTOXINS – AFFECT THE NERVOUS SYSTEM (BRAIN, SPEECH, MUSCLE CONTROL) ALLERGENS – WEAKEN IMMUNE SYSTEM ENDOCRINE DISRUPTOR – INTERFERES WITH THE ENDOCRINE SYSTEM (HORMONES, GROWTH, DEVELOPMENT, & SEXUAL MATURITY)

INDOOR AIR POLLUTION SIGNIFICANT AMOUNTS OF CHEMICAL HAZARDS ARE FOUND INDOORS *THINK ABOUT WHERE YOU SPEND MOST OF YOUR TIME* TYPES: ASBESTOS – MINERAL THAT FORMS IN LONG, THIN MICROSCOPIC FIBERS, USUALLY USED IN INSULATION IN BUILDINGS. WHEN DISTURBED, THESE FIBERS ARE RELEASED FROM THE INSULATION AND THEN INHALED. ONCE INHALED, THEY CAN GET STUCK IN THE LUNG TISSUE, CAUSING CANCER RADON – COLORLESS, ODORLESS, AND HIGHLY TOXIC RADIOACTIVE GAS. MADE NATURALLY IN THE GROUND, THEN SEEPS INTO BASEMENTS AND GETS TRAPPED IN THE STRUCTURE. VOC’S (VOLATILE ORGANIC COMPOUNDS) – RELEASED INTO THE AIR FROM PERFUMES, PLASTICS, AND PESTICIDES. *THINK ABOUT WHEN SOMEONE SPRAYS THEIR BODY SPRAY IN CLASS AND YOU START COUGHING*

TYPES CONTINUED CARBON MONOXIDE – COLORLESS, ODORLESS GAS. LOW LEVEL EXPOSURE CAUSES HEADACHES, DIZZINESS, AND NAUSEA. HIGH LEVELS RESULT IN DEATH. CARS RELEASE THIS (DON’T HAVE CAR RUN IN A CLOSED GARAGE) LEAD – CAN BE FOUND IN DRINKING WATER, CONTAMINATED SOIL, PAINT, AND AIR. CAUSES DAMAGE TO BRAIN, LIVER, KIDNEY AND STOMACH. 1/6 KIDS AFFECTED IN USA

BIOMAGNIFICATION ORGANISMS BUILD UP CHEMICALS IN THEIR BODIES AS THEY ARE EXPOSED TO MORE AND MORE AS YOU MOVE UP THE FOOD CHAIN, THIS LEVEL MAGNIFIES REALLY COMMON IN FISH CURRENTLY - MERCURY POISONING

HAZARD IMPACT THE IMPACT OF A HAZARD DOESN’T ONLY HAVE TO DO WITH THE TYPE OF HAZARD IT IS (URANIUM IS OBVIOUSLY BAD) BUT ALSO, HOW MUCH HAVE YOU BEEN EXPOSED TO (EVEN WATER CAN BE DEADLY IF ENOUGH IS DRANK). ALMOST ANY SUBSTANCE CAN BE HARMFUL IF EXPOSURE IS HIGH.
