Hare wys dalk uraangevaar

Die antwoord op uraanbesmetting in die Wonderfonteinspruit en Soweto lê moontlik opgesluit in mense se hare.

 

Die Internasionale Agentskap vir Kankernavorsing (IARC), ’n spesialiseenheid binne die Wêreldgesondheidsorganisasie (WGO), het in samewerking met die Federasie vir ’n Volhoubare Omgewing (FVO) en die Mynwaternavorsingsgroep by die Noordwes-Universiteit met ’n aanvoorstudie begin om te probeer vasstel of uraan opgehoop het in die hare van mense wat in gebiede rondom goudmynhope woon.

Mariette Liefferink, direkteur van die FVO, het gister gesê geen epidemiologiese studie oor die invloed van goudmynbedrywighede op menslike gesondheid bestaan in Suid-Afrika nie.

“Hierdie is die eerste stap om vas te stel wat in die liggaam gebeur wanneer mense jare lank aan die uraan in goudmynhope blootgestel is.

“As die laboratoriumtoetse wys uraan het wel in mense se hare opgehoop, sal die navorsing moontlik voortgaan in ’n volwaardige epidemiologiese studie.”

Die FVO versamel tans meer as 800 haarlokke. Die hare word gekry van agt haarkappers wat ingestem het om aan die studie deel te neem.

Vier van die haarkappers is in gebiede rondom goudmynhope (Diepkloof, Azaadville, Mindalore en Kagiso) en vier in kontrolegebiede (Randburg, Lenasia, Lau­dium en Alexandra).

Volgens Liefferink word elkeen wie se hare deel van die studie vorm, ingelig en moet hulle daartoe instem. Deelnemers sal egter nooit weet wat die uitslag van die studie is nie omdat hul name nie op die koeverte aangebring word waarin hul hare verpak word nie.

Die plek waar die hare vandaan kom en of dit dié van ’n vrou of ’n man is, sal wel op die verpakking aangedui word.

Sodra al die haarlokke ingesamel is, sal dit by drie verskillende laboratoriums getoets word, in Mahikeng, Frankryk en Duitsland.

Liefferink sê die FVO versamel tans ook haarlokke van tradisionele helers en mense wat in suurmynwater gedoop word, asook dié van mense wat weens geloofsgebruike sand van goudmyne aan hul gesigte smeer.

Die haarlokke sal einde Februarie aan die IARC gestuur word vir verspreiding na die verskillende laboratoriums.

. Die Nasionale Kankervereniging van Suid-Afrika (Kansa) het in 2012 begin met die versameling van verstandtande in Potchefstroom en Ventersdorp (as kontrolegebied) in ’n poging om ’n soortgelyke studie te doen. Kansa het by navraag gesê die studie is nog nie afgehandel nie.

Lauded for research on SA acid mine drainage

The launch of Acid mine drainage in South Africa: Development actors, policy impacts and broader implications, by Suvania Naidoo, took place on 10 February 2017. The book has proven to be a timely publication because of the incipient water crisis in South Africa. The event was hosted by Unisa’s Department of Development Studies in the College of Human Sciences. The guests were welcomed by the chair of the department, Prof Gretchen du Plessis, who expressed that “development studies is an ever-changing discipline and is a space where different issues converge”. She further stated that the book fills a void in our knowledge about acid mine drainage (AMD) and that the publication is “an example of hard work which results in big achievements”.

WATER

Eastern Basin acid water plant is "sledgehammer"

The Department of Water and Sanitation (DWS) has used a "sledgehammer" for its R1bn treatment plant for acid mine drainage (AMD) on the Eastern mining basin that could ultimately create more toxic water.  This is the view of water strategy and consulting mining hydrologist Kym Morton, who believes government is "wasting money" by pumping large volumes of water and adding lime that makes it alkaline but still toxic and hazardous.
