Back from Mexico – Removing Lead from a Tradition

Just returned from Mexico with Blacksmith’s globe-trotting program officer Bret Ericson (who’s also the task manager for our global inventory project).  For me, Mexico always brings to mind wonderful, colorful pottery, perhaps because there is a such a strong ceramics tradition there. Unfortunately, this tradition also involves the use of toxic lead-based glazes.  Even though there is now a lead-free alternative glaze that is available and CHEAPER,  it is a hard habit to break for the 50,000 or so Mexican potters. Because it is something so entrenched in their way of life, the potters are, in a way, blinded to the lead poisoning that goes on around them.

About 50,000 ceramics producers in Mexico use toxic lead-based glazes

A year ago, we entered into a partnership with Fondo Nacional Para El Fomento De Las Artesanias (FONART), a Mexican government agency that has been working on the problem (see Blacksmith August newsletter). We went back this time to collaborate with FONART and the Mexico Ministry of Environment on a 2-part plan to convince Mexican potters to stop using toxic lead in their ceramics glazes, and then to clean up the contamination.

We decided that to break the habit, we had to show the potters hard data to prove that they and their families are being poisoned. To do this, we are going to test their children to highlight their extremely elevated blood lead levels. Once the potters make the switch to lead-free glazes, we will launch into step 2 — cleaning up the lead contamination in the community.  We also plan to re-test  the children to show the corresponding drop in blood lead levels.  Cause and effect.  That’s the best way to educate and get change to happen.  That’s the way to spread the message from one family-run pottery to the next.

While in Mexico, we also hired a Mexico country coordinator for Blacksmith — Daniel Estrada.  Daniel will oversee the project on the ground.  One of his first tasks will be to train nurses to take blood lead samples from the potters’ children.

How to Build the World’s First Database of Polluted Sites

It’s been a good start to the year for us on the funding side. We just received confirmation that we will be getting a $900,000 infusion to complete work on our Global Inventory Project, which is about one-third done (see snapshot in my December 23 post). This new grant will allow us to hire more investigators and pay for equipment, travel and training for them.  It’s a big job — building the Global Inventory – the world’s first comprehensive database of polluted sites with human health impact.  Here is a behind-the-scenes look at what the grant is supporting/what our investigators are doing on the ground in over 60 countries:

Over the past year, we have been training teams of investigators around the world for the Global Inventory Project. These local teams are then dispatched to assess and collect data on polluted sites in their region using the Initial Site Assessment (ISA) protocol and other resources developed by Blacksmith. This ISA protocol involves a visit to the site and a review of key technical and historical information. Our investigators review and collect as much information as possible from all stakeholders, including local NGO’s, businesses, technical agencies, and governments. Samples are taken, where credible test results are not already available, and information collected is related to population and pollutant pathway.  This data is then used to calculate a ranking for the site on the Blacksmith Index, which assigns a number from 1 to 6, with the latter indicating the highest risk to human health from pollution. All site information is inputted into an online database and reviewed by a team of technical experts. Other experts conduct field visits for quality assurance purposes.

Only through this painstaking process will we be able to paint a first clear picture of the scope of life-threatening pollution. You really can’t solve a problem until you know its extent. By next year, our Global Inventory Project will give us just that.

Video of gold miners in Indonesia – Mercury: The Burning Issue

Amalgam of mercury and gold

Amalgam of mercury and gold

I first blogged about the toxic connection between gold and mercury back in December in my post All That Glitters, when the price of gold reached a record high.  Back then, we asked you to join our December Holiday Challenge and you came through – so far we have raised enough money to buy nearly 3,000 additional mercury-recapture retorts. Thank you. Now I have some video to show you so you can see how those retorts are making a difference.

Watch Mercury: The Burning Issue (Part 1) and Mercury The Burning Issue (Part 2) now.

We have been working with a local NGO in Indonesia to introduce these simple, low-cost retorts that gold miners can use to recapture mercury that is burned off in the gold mining process.  We took our cameras out to the mines in Kalimantan to talk to the miners themselves   One man explained that before the retorts,  “my head feels like it’s about to burst and it gets hard to breathe.” His only wish is for a bigger retort so he can process larger quantities.

Now that the price of gold is still high — I continue to see those ads on television asking you to mail in your gold for cash — it is a good time to stop and think where your gold comes from.  At least a quarter of the world’s total gold supply comes from artisanal gold mining in countries like Indonesia. These are small, very labor intensive operations. Often, men, women and kids work together. To understand what it is like on the ground, this video shows how the miners extract the gold – crushing the ore, mixing it with mercury, then burning the mercury off with a propane torch to recover the gold or adding cyanide to release the mercury.  Either way, mercury leaks into the air and environment, and gets absorbed into the ground, contaminating the water. One village of about 2000 people we visited had more than a dozen gold processing sheds.  The miners there have built their own retort but they are only 60% efficient, meaning 40% of the toxic mercury escapes into the air, poisoning everyone in the village.

Slowly we are  starting to make a difference.
