Institute of Occupational Medicine pesticides from food and other sources. This work demonstrated that although it is likely that most people are exposed to low levels of a wide variety of pesticide compounds it is unlikely that such exposure would have measurable effects on the health of the population. In 1995 the Soufriere Hills volcano on the Caribbean island of Montserrat erupted, spewing volcanic ash containing large amounts of the crystalline silica mineral cristobalite over the surrounding area. IOM scientists investigated the health of people who lived on the island. In general the exposure of the residents was low, because most people lived well
Devastation Trail and the intensity of the earthquakes also increased. By nightfall, the earthquakes stopped, and the eruption began. The fissure eruption produced fountains of lava which cascaded to the floor of the crater some 100 m below the erupting fissure. Forest fires were also noted. Over the next few days, the lava fountains became higher and higher, eventually reaching a height of more than 500 meters. Erupting pumice started building a new cinder cone that was later named " Puu Puai", (gushing hill). A lava lake also developed on the crater floor. The eruption produced both Pele's hair, the geological term
