The source of the epidemic was artisanal gold mining
that became prolific in 2009-10. For several months, ore processing was
conducted at numerous sites within the villages. Because local religious
and cultural practices include the sequestration of married women, ore
crushing, washing, and gold recovery were undertaken within the
residential compounds to utilize the women’s labor. At some point during
the rapid increase in mining activities, a dangerous ore exceeding 10%
lead was introduced, severely exposing young children, pregnant women,
and nursing mothers. By April 2010, with death and illness prevalent,
the local Emirates ordered a temporary suspension of artisanal ore
processing and later required that all operations be moved approximately
one-half kilometer from the villages involved in mining. However,
extremely hazardous exposures associated with residual waste and
contaminated soils remained in the residential compounds and exterior
processing areas.
Due to the continuing mortality, MSF/TG focused on
emergency medical treatment and environmental response. MSF, ZMOH, and
FMOH developed village chelation therapy clinics. However, all entities
agreed that returning treated children to contaminated homes would
compromise the treatment. Coupled with local resistance to relocation,
this required the villages to be remediated prior to commencing
chelation. Remediation continued over three and one-half years in three
phases, encompassing 8 villages and 17,000 residents. More than 2,300
children under five years of age received chelation therapy.
