Safer Mining Practices Reduce Hazardous Exposures—Study

A new study has showed that a pilot program to reduce lead poisoning in Nigerian gold mining communities has brought extraordinary improvements to an area where hundreds of children had died from lead poisoning.

The study authors concluded that a two-year effort to introduce safer mining practices was effective at preventing deaths and reducing lead poisoning in highly exposed villages.

“Our pilot project demonstrated that low-cost dust control measures were effective at reducing average airborne lead exposures by 95 per cent,” said Perry Gottesfeld, Executive Director of Occupational Knowledge International (OK International) whose organization partnered with Doctors Without Borders/ Médecins Sans Frontières (MSF) in this effort.

The safer mining project took place in the Shakira community in Niger State where high levels of lead are naturally present in the gold ore. The primary objective was to reduce lead exposures among artisanal small-scale miners and minimize take-home exposures.

“We worked cooperatively with miners to provide them with the information and tools to reduce their exposures to lead and silica dust. Together we showed that these efforts minimized contamination and helped save lives.” Gottesfeld said.

The organization demonstrated the effectiveness of reducing airborne lead levels by working with miners to convert dry operations into wet methods. Water spray misting was proven to be highly effective while minimizing water consumption. In addition to significant reductions in the airborne lead, the authors reported that these control measures reduced the smaller respirable silica dust by 80 percent.

Philip Aruna, Head of Mission in Nigeria for Doctors Without Borders said: “OK International has exceeded expectations in bringing an entire community together to prevent severe lead poisoning and by demonstrating significant reductions in lead exposures among miners.”

Gottesfeld noted that “Following our extensive outreach and training, these miners were motivated to take measures to reduce hazardous lead exposures and invested their own time and money to implement these protective measures.”

The authors of the Study “Reducing Lead and Silica Dust Exposures in Small-Scale Mining in Northern Nigeria” published in Annals of Work Exposures and Health noted that average lead exposures among ore processors before the implementation of safer practices were 19 times greater than the U.S. Occupational Safety and Health Administration (OSHA) permissible limit for lead.

In Nigeria and in most other African countries, there are no occupational limits for exposure for lead or silica dust.

Silica dust causes silicosis, lung cancer and is a significant risk factor for tuberculosis (TB). Lead causes severe neurological deficits and death among children in these communities, but even at low exposure levels is responsible for 674,000 deaths each year primarily due to cardiovascular disease.

There are an estimated 40 million informal small-scale miners working in at least 70 countries around the world. Although some programs have attempted to reduce mercury exposures in these communities, this is the first such intervention to demonstrate reductions in lead and silica dust exposures. The authors of the published article note that in mining communities lead and silica hazards pose a far greater risk to human health than the use of mercury.

Dr. Adolphe Fotso, Medical Coordinator for Nigeria with Doctors Without Borders, and an author on the paper said, “this effort was an extraordinary success in reducing these significant health risks and protecting children from lead poisoning.”

In addition to introducing wet methods, OK International focused on training miners to implement simple measures including handwashing, showering, setting up separate eating areas, and changing out of work clothing before going home at the end of the day. The study estimated that the overall cost for introducing these measures in this community was approximately $5,000.

The last trading session of the week at the Nigerian Autonomous Foreign Exchange Market (NAFEX) ended on a negative note for the Naira on Friday, May 15, as it lost N15 Kobo or 0.1 per cent against the Dollar to trade at N1,371.04/$1 compared with the previous day’s N1,370.89/$1.

However, it further appreciated against the Pound Sterling in the same market segment yesterday by N20.77 to close at N1,830.61/£1 versus Thursday’s value of N1,851.38/£1, and gained N7.91 against the Euro to settle at N1,595.07/€1 versus N1,602.98/€1.

At the GTBank FX desk, the Naira lost N2 against the US Dollar during the session to sell at N1,383/$1 compared with the preceding session’s N1,381/$1, and at the black market, it remained unchanged at N1,385/$1.

The Naira is forecast to be broadly stable, supported by Dollar sales by the Central Bank of Nigeria (CBN) amid steady, higher oil receipts, with the ‌market settling ⁠into a balance.

Policy direction is also expected to give the market some boost as the CBN said the new edition of the FX market guidelines will deepen liquidity, improve transparency and strengthen confidence in the country’s foreign exchange market.

According to the Governor of the CBN, Mr Yemi Cardoso, the update is due to changing global economic realities, domestic reforms and the need for a more coherent and forward-looking regulatory framework. According to him, the last edition of the FX manual was issued in 2018, making the latest review both timely and necessary.

Meanwhile, the cryptocurrency market plunged into the red zone as rising bond yields hit risk assets across markets, while traders are increasingly betting the Federal Reserve may need to raise rates again. Rising energy prices and resurging inflation could force central banks back into tightening mode.

Cardano (ADA) shrank by 4.4 per cent to $0.2557, Dogecoin (DOGE) slid by 3.7 per cent to $0.1104, Ripple (XRP) depreciated by 3.5 per cent to $1.41, Solana (SOL) crashed by 3.5 per cent to $87.81, and Binance Coin (BNB) slumped by 3.4 per cent to $659.64.

Further, Bitcoin (BTC) declined by 2.6 per cent to $78,547.49, Ethereum (ETH) lost 2.1 per cent to quote at $2,209.19, and TRON (TRX) tumbled by 0.7 per cent to $0.3509, while the US Dollar Tether (USDT) and the US Dollar Coin (USDC) traded flat at $1.00 each.
