Een onthullende spray laat elke loodverontreiniging felgroen oplichten

Toxicologie Een simpele spraytest toont gevoelig en onmiddellijk aan of een voorwerp vervuild is met lood. De vinding is een bijvangst uit het onderzoek naar loodvrije leds en zonnepanelen. „Wij hebben de gedachte omgedraaid.

‘We hebben de spray op allerlei gebruiksvoorwerpen uitgeprobeerd, het was voor ons verrassend in hoeveel alledaagse dingen lood zit”, zegt chemicus Lukas Helmbrecht.

Ook een theepot van mijn huisgenoot lichtte fel groen op. Die wordt dus niet meer gebruikt. Best jammer, het was een geliefde theepot.

Innovatieve Toepassing van de Looddetectiespray

De spray waardoor de theepot is verbannen detecteert lood. Helmbrecht ontwikkelde de spray samen met zijn collega Wim Noorduin van natuurkundig onderzoeksinstituut Amolf in Amsterdam. Ook de mooie wijnglazen die de ouders van Noorduin jarenlang bewaarden zullen nooit meer gebruikt worden, concludeerde hij na gebruik van de spray. De looddetectiespray bestaat uit een oplossing met methylammoniumbromide, dat reageert meteen als het in contact komt met een loodverbinding. Bij die reactie wordt een loodperovskiet gevormd, een specifieke kristalstructuur, dat groen oplicht wanneer het met uv-licht wordt beschenen.

Het is een nieuwe en verrassende toepassing van perovskiet, dat vooral onderzocht wordt als halfgeleidermateriaal voor zonnecellen en leds. Vorige week publiceerden Noorduin en Helmbrecht met enkele andere Amolfpromovendi over hun vinding in het tijdschrift Environmental Science and Technology.

Kinderen met loodvergiftiging

Het opsporen van loodverontreiniging is nuttig, want blootstelling aan lood komt veel voor en kan ernstige gevolgen hebben voor de gezondheid. In 2020 bleek uit onderzoek van Unicef en milieustichting Pure Earth dat 800 miljoen kinderen wereldwijd een loodvergiftiging hebben. Het loodgehalte in hun bloed is meer dan 5 microgram per deciliter, een grens waarboven volgens de wereldgezondheidsorganisatie actie moet worden ondernomen.

Thanks for putting this product out! One of my favorite mugs tested positive :( Sad. Also scary. I'm in the process of testing all my dishes, because man, I've been drinking out of a lead lined cup this entire time??? Geez.

So thankful I purchased this kit. I found a suspect pile of paint chips in my new apartment that was built in 1898 and this test was able to confirm it was lead paint and that I need to move out asap!

Before Lumetallix was invented, there wasn't a way for people without an XRF gun to test consumer products for lead.
I became lead aware after Corelle admitted that its pre-2005 dishes had lead (except for the plain white dishes--those are safe). I was really concerned about exposing my kids (and myself) to lead. I had no way to know which of my dishes were safe. I put away mugs and dishes that I thought could have lead, but I wanted to know for sure. So, I'm so grateful for this product! I bought a Lumetallix kit and tested a ton of my stuff at home.

Using the test, I identified lead in:
a Starbucks mug and soooo many promo mugs
my Wedgwood Peter Rabbit porringer :(
the white logo on my Bodum glass beaker
the lid of a pill box from Ireland

To test for lead using Lumetallix, just spray (or drip) some of the test liquid on your item, then see if that creates a green glow using the included UV flashlight. The test can detect lead down to 500 ppm.

People can post photos on the Lumetallix website of what they've found glowing using the test. It is so surprising what people have found that contains lead--bathtubs, dumbbells, yoga mats, vintage Pyrex mixing bowls, tire swings, Tiffany lamps, beer glasses, door/cabinet knobs.

I highly recommend buying this test to see if your stuff contains lead. I tested so much of my stuff that I ran out of the test liquid, and I just ordered a refill 2 days ago. It is definitely worth the money to have the peace of mind, knowing whether your things are safe or leaded.
Shipping from the Netherlands (where the company is based) to Canada took 8 calendar days.

5/5 Cannot recommend highly enough

An absolute MUST-HAVE for any family! Thanks to Lumetallix I started completely clearing my household of tons of lead products...I had no idea the amount of exposure to my children, pets and family!

I ordered the Lumetallix Test Kit, and it exceeded my expectations. The ease of use and accurate results make it an excellent value. I highly recommend it to anyone looking to safeguard their health from lead contamination.
