1
We're used to the idea that what looks and feels like fresh air can contain all sorts of dangers.
2
But the latest pollutants to concern us are actually in your home and mine.
3
They're microplastics, tiny fragments of plastic that are less than five millimeters in size.
4
We've come to one Sydney home to find out what lurks inside.
5
Hi Eleanor.
6
How are you?
7
I'm great.
8
I'm great.
9
Would you like to come in?
10
Yeah, I'll take my shoes off.
11
I've come to the home of Eleanor Saxon Mills,
12
a busy mum to one-year-old Sunny and four-year-old Ines.
13
Cup of tea?
14
I would love a cup of tea.
15
Yeah, black?
16
Yeah, just black, thanks.
17
Thanks so much.
18
That's great.
19
So what have you heard about microplastics before we came along?
20
I've heard only a little bit that it's everywhere,
21
especially in our food, and that there's huge amounts in us,
22
which is kind of a little bit terrifying.
23
But it is everywhere.
24
Yeah.
25
You know, I thought tea was safer.
26
What can be safer than tea and tea bags?
27
And then I discovered that even tea bags have microplastics in them.
28
You just can't escape it.
29
Yeah, that's crazy.
30
Do you want to show me around the kitchen?
31
We'll see what you've got.
32
Yeah, yeah, go right ahead.
33
So let's look at the fridge.
34
Yeah.
35
Let's show Dr. Norman all of our plastic in here.
36
I mean, it's very hard to buy stuff that's not wrapped in plastic.
37
Yeah, everything.
38
All sorts of plastic here,
39
no glass, just plastic bottles, plastic containers.
40
OK, show me your secret stash.
41
Yes, the Tupperware.
42
That's up here.
43
Let's lift you up here.
44
Here we go, the stash.
45
This is all the plates in here and plastic.
46
Do you put plastic in the dishwasher?
47
Yes.
48
Am I allowed to?
49
Yeah, there should be plastic in there now.
50
Oh, that's where it is, yes.
51
You know what they're saying about plastic and dishwashers these days.
52
Please don't tell me.
53
So what was here beforehand?
54
It was just grass and a hill's hoist and that was it.
55
Eleanor knows and does more than most when it comes to the environment.
56
She grows her own veggies and raises her own chooks.
57
They give us a couple of eggs a day, which is awesome.
58
So she's certainly keen to find out how to minimise potential microplastic danger inside the house.
59
What are microplastics?
60
Microplastics are those small bits of plastic.
61
They either come from fragments of larger plastics,
62
or they're intentionally added as microplastics to products.
63
But they can get very small indeed, can they?
64
They can.
65
We're now finding plastics down to the nanoscale,
66
so plastics just fragment over time.
67
They don't biodegrade within our lifetime.
68
They'll just get smaller and smaller under UV light or through action, fragments come off.
69
How do microplastics actually get inside your body?
70
Breathing it in, drinking and eating are the main sources.
71
The finer particles tend to settle in the bottom of the lungs and they move through the bloodstream,
72
across the membrane, because they're fine enough.
73
Similarly, with what food we eat,
74
you know, those smaller particles will move across the stomach wall and into the bloodstream,
75
and then they're distributed around the body.
76
The third major source is applying it on our skin.
77
Rather than assume where the highest exposure to microplastics are in Eleanor's house,
78
We're actually going to measure them over a few weeks.
79
We can't measure what microplastics Elner's family is eating,
80
but these petri dishes will catch the plastic fibres and particles they might breathe in from the air.
81
We'll have the results back in a couple of weeks.
82
It's hard to imagine a world without plastic.
83
It's in the clothes we wear,
84
the carpets we walk on,
85
the pans we use for cooking,
86
and the packaging in the supermarket.
87
Plastic production has grown more than 200-fold in the last 75 years and is showing no signs of slowing down globally.
88
There are around 16,000 chemicals in plastics,
89
and of the few which have been tested for safety,
90
a significant proportion shows signs of being harmful.
91
We did have a look in the kitchen,
92
but not in the cupboard.
93
Dr Scott Wilson has picked up the petri dishes from Eleanor's home and is analysing them in the lab.
94
Really in the home, it's the fibres.
95
It's 90% of what we're seeing are fibres like this on the screen.
96
And just at this fibre level,
97
can that have an effect on the body?
98
Yeah, I mean, we're breathing it in,
99
and so it can get trapped in the lungs.
100
The larger particles get expelled as we cough it out,
101
but the smaller particles get caught and reside there and can move across into the bloodstream.
102
He's also taken a sample from inside Eleanor's vacuum cleaner.
103
It picks up lots of plastics.
104
As you can see, there's some larger fragments there,
105
some smaller fragments, but they're heavier particles that just fall on the ground.
106
And is there any evidence that that sort of material is what we're ingesting?
107
Potentially, particularly with kids and babies crawling around on the ground.
108
The potential for human harm is significant.
109
It's not just the thousands of chemicals that have not been tested for safety.
110
There are contaminants and additives,
111
some of which have already been banned.
112
And then there's nanoplastics, which can get into the brain, perhaps causing inflammation.
113
The reality with microplastics is that we're flying blind, relying on animal studies.
114
If you put microplastics in the water with fish or with some invertebrates,
115
they'll change their growth behaviour and or die depending on the concentration.
116
There was a study done where they put microplastics in the water supply of mice
117
and the ones that had been exposed to microplastics were behaving as if they had early onset dementia.
118
I've come back to give Eleanor the results from the Petri dishes.
119
Where do you think was highest?
120
I actually think it was Sunny's bedroom
121
because we had it right next to where the nappies are
122
and every time I took a nappy out
123
or got his clothes out I just thought there's got to be a lot of plastic floating around here.
124
So it was your bedroom?
125
Oh really?
126
Yeah.
127
Oh, I would put that right down the bottom of the list.
128
I'm very surprised.
129
Second was the bathroom.
130
Okay.
131
Yeah.
132
And then in here and the play area.
133
Right.
134
And the kitchen, you know,
135
parts of the kitchen were high,
136
but the pantry was really low.
137
Right.
138
Okay.
139
Gosh, that really surprises me.
140
Yeah.
141
I don't think we have a lot of plastic sort of stuff in our room,
142
but maybe it's the clothes You don't,
143
but it's fibres, you see.
144
So what you get is the synthetic fibre off the carpet,
145
off the clothes and towels and what have you.
146
So it's kind of different.
147
You're thinking about the kitchen,
148
but in fact what you're getting there are the fibres.
149
And the same as in the bathroom,
150
but also in the bathroom you've got complications with cosmetics and things like that.
151
And as for the play area,
152
it was heaviest not so much in fibres but plastic fragments.
153
So do I have to chuck out all the kids' toys or the plastic?
154
How worried should I be?
155
A lot of parents are worried about this.
156
I'm not the expert.
157
They are progressively, some of them,
158
changing to wooden toys and so on.
159
What our resident expert Scott says is as long as you're vacuuming regularly,
160
whether it's the carpet or your wooden floor,
161
floor then you're getting rid of the plastic particles from the environment and that's probably the best thing you can do.
162
It's easy to get panicked about all this so it's important to remember that the evidence for harm is not solid,
163
well at least not yet.
164
The question is how long do you wait for proof?
165
So the experts say you should do what you can.
166
So here's what I've done.
167
I no longer wrap food in plastic wrap.
168
Certainly got rid of plastic chopping boards you just don't know what's breaking off there.
169
Plastic utensils which crumble in the heat.
170
Nonstick cookware has gone from my household,
171
gets scratched, you don't know what's coming off there.
172
Trying very hard to get rid of plastic containers.
173
Certainly don't put plastic in the microwave and don't put them in the dishwasher and replacing it with glass.
174
Anytime you use a high wash cycle
175
or high temperatures you are basically going to be eroding like micro erosion off the surface of those plastics
176
that you've got in there so you're actually creating microplastics by putting them in your dishwasher.
177
So have I scared you?
178
A little bit.
179
A little bit.
180
So what people talk about a lot is that when you're changing curtains,
181
renewing carpets, you look for natural fibres rather than synthetic mixes because that increases the flux of
182
microplastics into your environment in general but those are slow processes
183
and the interesting thing is that if everybody does that a little bit the market will change
184
should be good and protect the health of people like sunny in the years to come yeah thanks norman

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
