Unexpected Elements
The Soaring Price of Condoms

KyllÀ, se nÀyttÀÀ hieman yksinkertaiselta, mutta asia on se, ettÀ koalat ovat todella hyvÀt syötÀjÀt. He pystyvÀt kasvamaan vain muutamia yksilöitÀ eukalyptoista. Ja Suomalaisessa EstÀ-Australiassa he ovat yliopistoneet manna-kummi-eukalyptoista paikoillaan. Ja jos se tapahtuu, se tappaa koalaa ja se voi edistÀÀ isoja koalapopulaita, jotka ovat syötÀneet.

Ne ovat yksityiskohtaisia nÀissÀ pienissÀ alueissa. Joten tÀmÀ on yksi tehtÀvÀ, jotta voimakkaus ei pysy. KyllÀ, se on melkein se, mitÀ tapahtuu. Mutta ainakin on helpompaa antaa koalaan kontraseptiivisen implantin, kuin antaa afrikkalaisen elokuvan, joka on sama kuin syrjintÀkontrollin pilli.

Yes, I'd say that that's an interesting job. Does anyone have to do that? I mean, I imagine it's going to be a bit harder to just grab hold of an elephant. You've got bigger bodies, bigger appetites, bigger territories. Bigger feet to stomp you with and also a bigger nose to smack you with.

Managing elephant populations is a real hot button issue over here in southern Africa, because very few populations can roam as widely as they need to, since they're all corralled inside closed off reserves. And as with the koalas, if their numbers outpace what the landscape and the vegetation can support, they'll also end up starving. Usually numbers are managed with culling or relocating.

Unexpected Elements

Kulling is horribly cruel. You know, elephants are highly intelligent, they have sophisticated cultures, really sophisticated social structures. And then of course relocating is super expensive. Okay, so contraception is much easier in theory. In practice, how do they do it?

No, minulla oli Dr. Audrey Delsink, joka on Suomalaisen Suomalaisen yliopistossa Afrikassa. HÀn kertoi minulle metodin, jonka he suosittelevat ja suosittelevat. Kaikki, mitÀ tarvitset, on kÀynti, jonka jÀrjestÀjÀ ja kestÀvÀ kÀynti, ja jonka jÀrjestÀjÀ, jonka jÀrjestÀjÀ ja kestÀvÀ kÀynti.

Jotkut jÀttÀvÀt kivun, jolla on ensimmÀinen kivu. Jotkut heittÀvÀt hÀnet kivuun, joka kÀsittelee taitoja ja purpaa kivua, jotta hÀnet tietÀÀ, millainen kivu on. Jotkut jÀttÀvÀt kivun, jolla on ensimmÀinen kivu, jota hÀnet tietÀÀ, millainen kivu on.

KyllÀ, se on hieno kysymys. He ovat yrittÀneet tÀtÀ. He antoivat joitakin vanhempien elÀinten visektomia, ja he halusivat nÀhdÀ, onko animali- tai ryhmÀtyötÀ muuttunut. Ja se ei ollut. Joten kysyin Dr. Dalsinkista, miten nÀmÀ kaksi asiaa verrattuna. Ja hÀn sanoi, ettÀ viimeisen elÀinten visektomien kohdalla se toimii noin 130 euroa elÀinten per vuosi.

Vesektominen koulutus on todella kalliikkaa. Ja oikeastaan veterinaarien taitoja on erittÀin erilaisia. Joten se tulee hieman liian haastavaa. Hieman helpompaa. Sandy, missÀ haluat ottaa meitÀ seuraavaksi? Minulla on hieman mysterytÀ sinulle tÀnÀÀn. Se ei ole tÀysin selvÀÀ, miten tÀmÀ liittyy kondomille. Mutta pysyÀni minulle. Toivon, ettÀ se on tarpeeksi. MinÀ olen tÀÀllÀ mysterytÀ, joten menetÀÀn.

So some time ago, a multidisciplinary team of researchers from the University of Michigan were working together on a project. And they were trying to figure out how many microplastics people in their city were inhaling while outdoors. Just to be clear, a microplastic is a piece of plastic that's smaller than... About five millimeters, which is roughly the size of a pencil eraser. But that's the high end of the scale. They actually go down to much, much smaller than that.

Unexpected Elements
The Soaring Price of Condoms

Mikroplastiitit ovat löytyneet kaikessa ja kaikessa. IhmisissÀ ne ovat löytyneet sydÀn, sydÀn, rauha, kÀrsikot, placenta, kÀrsikot, ja niin edelleen. LisÀksi tutkijat ovat löytÀneet mikroplastiitit paikoissaan Mariana-trenkissÀ, joka on yksi laajimmista osista maata, ja myös Mount Fujiin ylÀpuolella.

So anyway, back to the project. The Michigan researchers had to collect air samples, but when they analysed the results, they were shocked to discover that the microplastic counts in the air were way higher than expected. We're talking more than 1,000 times higher. Wow, okay, that's a lot higher. So this is our mystery, right? This is our mystery, yes.

It led the researchers on what they described to be a wild goose chase. They started sampling things in the lab that were made from plastics that could have possibly contaminated the samples. They tested things like plastic squirt bottles, the lab's atmosphere, and eventually they traced it to the lab gloves they were using.

Unexpected Elements
The Soaring Price of Condoms

So these gloves were made from nitrile and latex, which are two very commonly used materials when it comes to lab gloves. Okay, and there's our connection to the news story. It's latex. But as we discussed at the start, latex is rubber, not plastic. So what's the contaminant? So it turns out that these types of gloves contain something called stearates. Now these are soap-like particles that manufacturers add to disposable gloves to help them separate easily from the moulds that are used to make them.

Unexpected Elements

Kuten sinÀ oikeasti sanoit, Marni, nÀmÀ eivÀt ole plastikkoja, mutta niillÀ on erittÀin erilaisia kemikaalistuksia kuin polyethylen, joka on yksi suurin tyyppi plastikkoja, joita löydÀmme ympÀristössÀ tÀnÀÀn. Ja siksi steroidit ovat vaikuttaneet mikroplastikkojen testaukseen. He löysivÀt, ettÀ nÀmÀ nitroli- ja latexluvut kÀsittelevÀt noin 7000 steroidia per kuusi millimetriÀ. Ja lopputulos tÀstÀ koko tutkimuksesta on se, ettÀ ehkÀ jotkut tutkijat ovat ymmÀrtÀneet ymmÀrtÀvÀsti mikroplastikkojen tasoja tutkimuksessaan.

Unexpected Elements

This is interesting. I can think of a solution, and that means getting completely naked in the lab when they do the sampling. I imagine, though, that it would probably be a bit of a breach of office protocol, though. Sandy, what solution did they come up with?

Unexpected Elements
The Soaring Price of Condoms

Unfortunately, I don't think anyone's going to bite on the naked researchers solution. But what these Michigan researchers found was that clean room gloves actually perform better than nitrile and latex gloves in the sense that they release far fewer chemicals.

Unexpected Elements

Ne tekevÀt kÀytÀnnössÀ samaa asiaa kuin muissa tyypillisissÀ tyypillisissÀ tyypillisissÀ tyypillisissÀ tyypillisissÀ tyypillisissÀ tyypillisissÀ tyypillisissÀ tyypillisissÀ tyypillisissÀ

KyllÀ, toivottavasti. Ja tÀmÀ on juuri se, mitÀ tutkijat kÀsittelevÀt paperissaan. Mikroplastiikki-alueet voivat olla ylipÀÀnsÀ ylipÀÀnsÀ ylipÀÀnsÀ ylipÀÀnsÀ ylipÀÀnsÀ ylipÀÀnsÀ ylipÀÀnsÀ ylipÀÀnsÀ

Thank you, Sandy. So, we've started with the price of prophylactics and via koala contraceptives we've just heard how rubber gloves may be shedding and muddying the waters when those waters are microplastic samples. Still to come on the show, whatever happens to the male contraceptive? Find out after this.
