  • HOME OF THE PBS NEWSHOUR,

  • WEEKNIGHTS ON PBS.

  • JOHN: THERE'S A CLASS OF TOXIC

  • CHEMICALS SO PERVASIVE THAT THEY

  • ARE FOUND IN FOOD, SOIL, WATER,

  • AND IN THE BLOOD OF MOST PEOPLE

  • IN AMERICA.

  • EARLIER THIS MONTH, THE EPA

  • PROPOSED THE FIRST-EVER

  • REGULATORY STANDARD TO LIMIT THE

  • QUANTITY ALLOWED IN DRINKING

  • WATER.

  • ALI ROGIN LOOKS AT THE GROWING

  • HEALTH CONCERNS ABOUT THESE

  • CHEMICALS.

  • ALI: PFAS, SOMETIMES CALLED

  • FOREVER CHEMICALS, REPEL FIRE,

  • WATER, OIL AND STAINS AND HAVE

  • BEEN USED SINCE THE 1940S IN A

  • WIDE VARIETY OF EVERYDAY

  • PRODUCTS.

  • YOU CAN FIND THEM IN NONSTICK

  • COOKWARE, FAST FOOD WRAPPERS,

  • CLOTHES, AND COSMETICS.

  • BUT THESE MAN MADE CHEMICALS

  • DON'T BREAK DOWN EASILY, AND A

  • NUMBER OF THEM HAVE BEEN LINKED

  • TO SERIOUS HEALTH PROBLEMS.

  • FOR MORE ON THEIR IMPACT, WE

  • TURN TO ERIN BELL.

  • SHE'S AN ENVIRONMENTAL

  • EPIDEMIOLOGIST AT THE STATE

  • UNIVERSITY OF NEW YORK AT ALBANY

  • WHO STUDIES HUMAN EXPOSURE TO

  • THESE TOXINS.

  • ERIN, THANK YOU SO MUCH FOR

  • JOINING US.

  • JUST HOW WIDESPREAD ARE THESE

  • CHEMICALS?

  • ERIN: THESE CHEMICALS HAVE BEEN

  • DETECTED IN THE DRINKING WATER

  • AND SOIL IN EVERY STATE OF THE

  • UNITED STATES, AND IT IS ALSO

  • BEING DETECTED IN MANY COUNTRIES

  • ACROSS THE WORLD.

  • A NUMBER OF HEALTH CONCERNS ARE

  • RELATED TO EXPOSURE TO THESE

  • CHEMICALS.

  • THEY INCLUDE IMPACT ON THE

  • IMMUNE SYSTEM.

  • FOLKS WITH HIGHER EXPOSURES

  • ARE MORE LIKELY TO HAVE THYROID

  • CHANGES, CHANGES IN KIDNEY

  • FUNCTION, AS WELL AS HIGHER

  • CHOLESTEROL.

  • WE'RE ALSO CONCERNED ABOUT

  • IMPACTS ON CHILDREN WITH REGARDS

  • TO LOW BIRTH WEIGHT AND

  • NEURODEVELOPMENT IN THOSE

  • CHILDREN.

  • AND THERE ARE A NUMBER OF OTHER

  • HEALTH OUTCOMES WHERE THE

  • LITERATURE IS MORE MIXED.

  • WE SOMETIMES SEE AN ASSOCIATION,

  • OTHER TIMES WE SEE LESS OF AN

  • ASSOCIATION AND WE HAVE MORE

  • WORK TO DO.

  • THESE WOULD INCLUDE INFERTILITY

  • FACTORS AROUND ULCERATIVE

  • COLITIS AND OTHER AUTOIMMUNE

  • DISEASES.

  • ALI: AND ARE THESE THINGS THAT

  • PEOPLE CAN DETERMINE BY TAKING A

  • BLOOD TEST?

  • I MEAN, HOW HOW DOES ONE TEST TO

  • SEE WHERE THEIR LEVELS ARE?

  • ERIN: THAT'S CORRECT.

  • SO FOR EACH INDIVIDUAL, WE

  • MEASURE CONCENTRATIONS IN THEIR

  • BLOOD, AND THAT IS THE BEST WAY

  • TO DETERMINE THE INDIVIDUAL

  • LEVEL OF EXPOSURE FOR PEOPLE WHO

  • HAVE LIVED IN COMMUNITIES OR

  • FOR PEOPLE IN OCCUPATIONS THAT

  • HAVE THESE HIGHER EXPOSURES.

  • UNFORTUNATELY, THERE'S NO

  • CONSISTENT GUIDANCE OR COVERAGE

  • FROM INSURANCE COMPANIES FOR

  • TESTING FOR PFAS IN YOUR BLOOD.

  • IF YOU CONTACT YOUR LOCAL HEALTH

  • DEPARTMENT, THEY WILL LET YOU

  • KNOW IF THERE ARE PROGRAMS AT

  • THE STATE LEVEL SPONSORED

  • THROUGH STATE HEALTH

  • DEPARTMENTS, IF THEY HAVE

  • OPPORTUNITIES FOR YOU TO GET

  • TESTED.

  • BUT THIS IS A SITUATION THAT

  • WE'RE STILL WORKING ON IN TERMS

  • OF MAKING SURE THERE'S COVERAGE

  • FOR PEOPLE TO GET TESTED IF THEY

  • WISH TO KNOW WHAT THEIR LEVELS

  • ARE.

  • ALI: NOW, THE EPA, AS WE

  • MENTIONED IN THE INTRODUCTION,

  • IS PROPOSING A NEW REGULATION

  • PERTAINING TO PFAS IN WATER.

  • CAN YOU EXPLAIN WHAT EXACTLY

  • THIS PROPOSAL WOULD DO?

  • ERIN: THERE ARE 12,000 CHEMICALS

  • IN THE FAMILY OF PFAS.

  • THE EPA HAS SUGGESTED THAT FOR

  • SIX OF THESE CHEMICALS, THERE

  • SHOULD BE A STANDARD FEDERAL

  • RULE THAT WOULD REQUIRE THAT

  • WATER UTILITIES TEST FOR THESE

  • SIX CHEMICALS.

  • AND IF THEY WERE ABOVE A CERTAIN

  • LEVEL, THAT THOSE LEVELS BE

  • MONITORED FOR AND COMPANIES BE

  • REQUIRED TO REDUCE THEIR

  • EXPOSURE IN THE WATER UTILITY.

  • ALI: NOW SIX OUT OF 12,000

  • DOESN'T SOUND LIKE A LOT.

  • ARE WE MISSING SOMETHING HERE?

  • ARE THESE VERY SIGNIFICANT

  • VERSIONS OF THESE CHEMICALS?

  • ERIN: SO THAT'S AN EXCELLENT

  • QUESTION.

  • AND THIS IS ONE OF THE

  • CHALLENGES WE HAVE IN THE FIELD.

  • OUT OF THE 12,000, WE'VE

  • OBVIOUSLY STUDIED VERY FEW OF

  • THEM.

  • SO THESE SIX ARE PARTICULARLY OF

  • CONCERN BECAUSE WE KNOW THE MOST

  • ABOUT THEM.

  • WE ALSO HAVE DETECTED THEM IN

  • HIGHER LEVELS IN DRINKING WATER

  • ACROSS THE COUNTRY.

  • HOWEVER, IT IS QUITE LITERALLY A

  • DROP IN THE BUCKET.

  • IT IS JUST A VERY SMALL NUMBER.

  • THERE IS CONCERN IN THE

  • SCIENTIFIC COMMUNITY THAT WE

  • WILL NEVER CATCH UP IN TERMS OF

  • UNDERSTANDING WHAT THE HEALTH

  • EFFECTS ARE FOR THE MUCH LARGER

  • GROUP OF PFAS'S.

  • ALI: HOW IS IT THAT THESE

  • COMPANIES ARE ABLE TO CONTINUE

  • TO MANUFACTURE PRODUCTS WITH

  • THESE DANGEROUS CHEMICALS IN

  • THEM?

  • ERIN: SO HISTORICALLY, WHEN WE

  • TALK ABOUT ENVIRONMENTAL

  • EXPOSURES AND REMOVING THEM FROM

  • PRODUCTION, WE FOCUS ON THEIR

  • PERSISTENCE.

  • THEY STAY IN THE ENVIRONMENT AND

  • IN OUR BODIES FOR A VERY LONG

  • TIME.

  • THE NEWER VERSIONS ARE NOT AS

  • LONG LASTING IN THE ENVIRONMENT,

  • HOWEVER, BECAUSE THEY ARE

  • STRUCTURALLY DESIGNED TO IN

  • ESSENCE DO THE SAME THING THAT

  • MADE THEM GOOD FOR PRODUCTION

  • AND FOR OUR CONSUMER PRODUCTS.

  • THEY'RE STILL RELATED TO SOME OF

  • THESE ADVERSE HEALTH OUTCOMES.

  • SO THEY'RE STILL BEING USED

  • BECAUSE WE HAVE NOT REGULATED

  • THEM AND WE STILL REQUIRE THEM

  • IN THE MANUFACTURING PROCESS.

  • AND UNTIL THOSE RULES AND LAWS

  • CHANGE, THEN THAT WILL BE

  • ALLOWED TO HAPPEN.

  • ALI: SO MY UNDERSTANDING IS THAT

  • THIS EPA RULE, IF IT IS

  • APPROVED, IS STILL GOING TO TAKE

  • A FEW YEARS BEFORE IT'S FULLY

  • OPERATIONAL.

  • SO WHAT KIND OF THINGS CAN

  • PEOPLE DO IF THEY WANT TO BEGIN

  • REDUCING THEIR EXPOSURE NOW?

  • ERIN: THERE ARE A NUMBER OF

  • THINGS THAT PEOPLE CAN DO AND

  • COMMUNITIES CAN DO.

  • THE FIRST IS AWARENESS.

  • PLEASE BE SURE AND KEEP MINDFUL

  • OF WHAT MIGHT BE GOING ON IN

  • YOUR COMMUNITY, ESPECIALLY IN

  • THE DRINKING WATER.

  • IF YOU ARE NOT SURE WHAT THE

  • LEVELS OF PFAS ARE IN YOUR

  • DRINKING WATER, YOU CAN CONTACT

  • YOUR LOCAL WATER UTILITY, YOUR

  • STATE HEALTH DEPARTMENT, AS WELL

  • AS ANY UNIVERSITY OR COLLEGE

  • RESEARCHERS THAT ARE IN THE

  • AREA.

  • IN TERMS OF REDUCTION, WE CAN

  • USE FILTERS ON OUR WATER SYSTEMS

  • AND IN OUR HOMES.

  • YOU ALSO WANT TO BE MINDFUL OF

  • WHAT YOU USE ON AN INDIVIDUAL

  • BASIS.

  • AGAIN, MINIMIZING FAST FOOD

  • WRAPPERS, THE WRAPPERS ARE LINED

  • WITH THESE MATERIALS AS WELL AS

  • MICROWAVE POPCORN IS ANOTHER

  • EXAMPLE.

  • POTS AND PANS HAVE THESE LININGS

  • .

  • AS THEY BECOME SCRATCHED THE

  • PFAS CAN LEACH INTO THE FOOD AND

  • CAUSE US MORE EXPOSURE.

  • SO AGAIN, BE MINDFUL OF THAT.

  • AND AS YOU REPLACE THEM WITH

  • THINGS THAT ARE NONSTICK WITH

  • THAT DON'T HAVE THE NONSTICK

  • CHEMICALS OR HAVE THE OTHER

  • TYPES OF COATINGS ON THEM THAT

  • WOULD POTENTIALLY HAVE THESE

  • CHEMICALS.

  • ALI: ERIN BELL WITH SUNY ALBANY,

  • THANK YOU SO MUCH FOR YOUR TIME.

  • ERIN: THANK YOU.
