SWDAYS) Science Jack HASTINGS Gas-containing ivater cause of lake deaths nlore than 1,500 African tribal III people died in their sleep on Aug. 21 at Lake Nyos in Cameroon, Overcome by a mysterious gas which erupted from the lake and drifted over nearby villages. A Belgian chemist, W.R. Ruston of Brussels, has concluded that whatever the cause, water containing gas from the deep high-pressure zone of the lake leached the upper low-pressure zone where spontaneous degassing triggered self-sustaining eruptive process that lasted until the total overturn of the lake's water. Ever since the mysterious deaths occurred scientists of many disciplines have sought to explain how it happened.

At the time, all that was known was that on Aug. 21 something apparently triggered the release of poisonous gas from Lake Nyos (also spelled Nios). The gas drifted from the lake to nearby villages where men, women and children were overcome as they slept On the surrounding hills some 2,000 livestock were found dead by the first rescuers to appear at the scene. In a letter to Chemical and Engineering News, Washington, Ruston explained what probably happened at Lake Nyos on that fateful night in August He said convection, an accidental idestabilization of the lake's vertical structure, led to an uncontrolled iipwelling of gas-bearing waters at an exponentially increasing rate and resulted in an explosion with catastrophic consequences. Ruston's letter was published in the magazine's Dec.

1 edition. Ruston's explanation is very likely jcorrect, according to Dr. Datta V. Naik, chemistry department chairman at tMonmouth College, West Long Branch. was one of the first to explain the action of gases immediately following the tragedy at Lake Nyos.

I The incident at Lake Nyos resembled what took place just two earlier, on Aug. 15, 1984, at Lake Monoun, 150 miles from Lake Nyos. Because both lakes are in volcanic at first it was thought that some 'volcanic activity resulted in an 'upwelling of poisonous gases. However, that is not thought to have been the cause. I Gases from rotting matter may lie 'for hundreds of years in lakes.

Limnologists who study lakes say August is the time of minimum 'stability for lakes in Cameroon. The Belgian chemist, Ruston, studied the findings of a Belgian research team which in 1953 made a study of the great lakes in Africa. A study of Lake Kivu, which resembles Lake Nyos, showed it contained large amounts of carbon dioxide and methane. Both lakes are very deep and V-shaped. The Belgian expedition found gases at a depth of 275 meters downward in Lake Kivu.

Kivu is at the frontier between Zaire and Rwanda. The 4 principal gases found were methane, 25 percent, carbon dioxide, 74 percent, and small amounts of hydrogen sulfide 5 and inert gases. 4 On average, Ruston said, one cubic meter of water was found to contain 1.62 cubic meters of gas at normal temperature and pressure. At Lake Nyos, contrary to earlier i assumption, there never was any "gas bubble" at the bottom that suddenly J. could have burst, Ruston said.

The gas present was simply dissolved in the t- water under high pressure. i I "It could have been present at a depth below 200 meters (220 yards) for I thousands of years," Ruston said. He theorized that a relatively minor event may have upset the lake's precarious equilibrium. A large boulder railing down the slopes may have accelerated a column of gas-containing water toward the surface. However, Ruston doesn't discount the possibility 4 that an injection of hot volcanic if magma at the lake bottom might also i have been responsible.

i But whatever the cause, gas from I the deep reached the upper low-i pressure zone where a spontaneous degrassing triggered a self-sustaining total overturn of the lake water. Cooking or heating fires in villagers' huts may have ignited the seeping gas, causing the bum injuries later found on the bodies of victims. 1 Naik of Monmouth College, who has worked on gas research for the Air Force and NASA research projects, believes the Belgian chemist is right about Lake Nyos. "His theory is the best of all I have heard on the subject," he said. "In all probability Lake Nyos, prior to eruption, was similar to Lake Kivu." Peter Kilham of the University of Michigan has described the rotten-egg smell of deadly hydrogen sulfide he encountered up to eight miles from lakes in Tanzania.

He also said gases from decaying matter are held in the lakes until the lake waters turn over. However, he said, in Africa the water of very deep V-shaped lakes are sheltered from the winds by high cliffs around the lake. The lake water may not turn over for many years, with the result that lethal gases accumulate, slowly gathering force. Jack Hastings is a staff writer for The Asbury Park Press.
