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 NASD Over-the-Counter (OTC) Securities Exchange further appreciated by 0.23 per cent on Thursday, April 23, with the Unlisted Security Index (NSI) adding 8.99 points to close at 3,969.96 points against the previous day’s 3,968 points.

The rise in the share price of Central Securities Clearing System (CSCS) Plc by N2.86 to N69.34 per unit from N66.48 per unit raised the market capitalisation of the NASD bourse by N5.38 billion to N2.380 trillion from N2.375 trillion.

Yesterday, there were two price losers, led by Food Concepts Plc, which lost 29 Kobo to sell at N2.65 per share versus N2.94 per share, while UBN Property Plc dipped by 22 Kobo to N2.03 per unit from N2.25 per unit.

During the session, the volume of securities traded declined by 97.9 per cent to 451,522 units from 21.5 million units on Wednesday, the value of securities depreciated by 52.32 per cent to N23.6 million from N49.5 million, and the number of deals depreciated by 3.6 per cent to 27 deals from 28 deals.

At the close of business, Great Nigeria Insurance (GNI) Plc remained the most active stock by value on a year-to-date basis with 3.4 billion units valued at N8.4 billion, followed by CSCS Plc with 59.5 million units exchanged for N4.0 billion, and Okitipupa Plc with 27.8 million units traded for N1.9 billion.

GNI Plc also closed the day as the most traded stock by volume on a year-to-date basis with 3.4 billion units worth N8.4 billion, trailed by Resourcery Plc with 1.1 billion units transacted for N415.7 million, and Infrastructure Guarantee Credit Plc with 400 million units sold for N1.2 billion.

Fresh foreign exchange (forex) demand pressure saw the Naira depreciate against the United States Dollar in the Nigerian Autonomous Foreign Exchange Market (NAFEX) on Thursday, April 22, by N5.46 or 0.4 per cent to trade at N1,353.91/$1 compared with the preceding day’s value of N1,348.45/$1.

It was the same outcome for the local currency in the official market after it depreciated against the Pound Sterling by N4.13 to close at N1,825.88/£1, in contrast to the preceding session’s N1,821.75/£1, and against the Euro, it dropped 72 Kobo to finish at N1,582.72/€1 versus N1,582.00/€1.

But the Nigerian Naira appreciated against the US Dollar at the GTBank FX desk by N2 during the session to quote at N1,361/$1 compared with Wednesday’s closing price of N1,361/$1, and at the parallel market, it closed flat at N1,375/$1.

FX Pressure came as data showed that NFEM interbank turnover was N28.117 million, lower than the N66.084 million recorded the previous day.

Concerns over liquidity pressures, policy transparency, and confidence in Nigeria’s FX market continue to grip the market while the country’s foreign reserve declines further, even as the Central Bank of Nigeria (CBN) recently said that the recent decline in Nigeria’s external reserves should not be a cause for concern.

Global developments also played a significant role, as rising geopolitical tensions boosted demand for the US Dollar, further weakening emerging market currencies, including the Naira.

As for the cryptocurrency market, there was a mixed outcome as traders reacted to rising geopolitical tensions from the Iran war and fresh inflation data from Japan.

Japanese inflation ticked higher in March, stoking expectations that the Bank of Japan may soon signal rate hikes, which could strengthen the yen and unsettle global risk assets.

The Iran conflict has disrupted oil flows through the Strait of Hormuz, raising energy costs and inflation risks worldwide and potentially complicating efforts by the Federal Reserve to cut interest rates.

Ethereum (ETH) declined by 1.8 per cent to $2,316.53, Bitcoin (BTC) lost 0.6 per cent to sell at $77,935.53, Solana (SOL) fell by 0.5 per cent to $85.67, and Binance Coin (BNB) dropped 0.4 per cent to sell for $634.85.

However, Dogecoin (DOGE) appreciated by 1.4 per cent to $0.0976, Ripple (XRP) grew by 0.7 per cent to $1.43, Cardano (ADA) expanded by 0.6 per cent to $0.2493, and TRON (TRX) improved by 0.2 per cent to $0.3279, while the US Dollar Tether (USDT) and the US Dollar Coin (USDC) traded flat at $1.00 each.

The resilience shown by Nigerian Breweries Plc in the 2025 fiscal year, despite a volatile macroeconomic environment, which consumed several businesses, has not got without notice.

Shareholders of the brewery giant applauded the board and management for the strong recovery and improved profitability recorded in the year.

At the company’s 80th Annual General Meeting (AGM) on Wednesday, April 22, 2026, in Lagos, they attributed these achievements to disciplined cost management and a significant reduction in finance expenses.

“We are proud of how the company has withstood the ups and downs of a challenging environment. The return to profitability and the reversal of the negative cash position recorded in the previous two financial years are commendable,” a member of the Noble Shareholders Association, Mr Owolabi Opeyemi, said at the gathering.

Also, the immediate past Secretary of the Independent Shareholders Association of Nigeria (ISAN), Mr Eke Emmanuel, noted that the company’s resilience reflects strong leadership and a sound strategic direction.

“It is good news that we have been here for 80 years. There is no reason why we will not be here for the next 80 years with what we have achieved. To return to this level of profitability and cash position shows the Board has done an enormous amount of work,” he said.

Addressing investors at the AGM, the board chairman, Mrs Juliet Anammah, expressed confidence that the company is firmly on a recovery path following the net losses recorded in the past two years due to macroeconomic pressures and fiscal reforms.

She thanked shareholders for their continued support and reaffirmed that the company will build on its 2025 performance as it accelerates growth ambitions.

“We have a solid foundation built over eight decades, anchored on a strong portfolio of brands, an extensive nationwide sales and supply chain network, ongoing digital transformation, and most importantly, our people. These strengths remain critical to sustaining our leadership position,” the former chief executive of Jumia Nigeria said.

Ms Anammah also addressed the company’s dividend position, noting that the decision not to declare a dividend reflects the need to rebuild retained earnings impacted by prior macroeconomic shocks, particularly foreign exchange-related losses.

“We recognise the importance of dividend payments to our shareholders and sincerely appreciate your continued understanding. While we are not declaring a dividend at this time due to negative retained earnings, we are working diligently to restore the company’s financial position and return to dividend payments as soon as it is sustainable to do so,” she added.

She further noted that the board remains vigilant to external risks, including the Middle East crisis and broader macroeconomic challenges, which may impact the pace of improvement in the 2026 financial year.
