Mining activities in Kenya, including artisanal gold mining, quarrying, and industrial mining, create occupational and environmental health impacts affecting workers and surrounding communities. Artisanal and small-scale gold mining (ASSGM) has expanded rapidly in western Kenya driven by economic opportunities and poverty, with miners using mercury in gold extraction. Mercury exposure causes neurological damage, kidney disease, reproductive effects, and developmental effects in children of exposed pregnant women. Acute mercury poisoning causes tremors, mood changes, and cognitive impairment. Chronic exposure causes peripheral neuropathy, renal dysfunction, and psychological effects.
Mining dust inhalation causes silicosis (fibrosis of lungs from silica dust exposure) and other respiratory diseases. Particulate matter exposure reduces lung function and causes chronic respiratory disease. Noise exposure from mining equipment causes hearing loss. Physical trauma from accidents with inadequate safety measures causes crush injuries, fractures, and disability. Mining workforces often include children, reducing school attendance and creating hazardous exposure during critical developmental periods.
Water pollution from mining contamination with heavy metals and chemical inputs affects drinking water sources for mining communities. Acid mine drainage from inactive mines continues creating environmental hazards years after mining ceases. Soil contamination from mining activities reduces agricultural productivity and creates ingestion exposure for populations consuming contaminated food. Communities downstream from mining sites experience disease burden from contaminated water supplies.
Occupational health services for miners remain limited, with no organized health surveillance or occupational disease management in most artisanal mining communities. Miners lack knowledge of hazards and prevention measures. Personal protective equipment is unavailable or unused due to cost, discomfort, or lack of awareness. Health facilities lack capacity to diagnose and manage mining-related occupational diseases. Worker organizing for safety improvements has been limited in artisanal mining sectors.
Strengthening mining health and safety requires regulation of mining activities, provision of occupational safety training and protective equipment, health surveillance for mining workers identifying early disease, and environmental monitoring preventing community contamination. Transition of workers from hazardous artisanal mining to safer alternative livelihoods would reduce exposure. Remediation of abandoned mining sites prevents ongoing environmental contamination. However, mining workers' economic dependence on mining makes livelihood transition challenging without alternative income sources. Sustained government commitment to mining health and safety remains necessary for protecting worker and community health.
