In 1700, Dr. Bernardino Ramazzini, considered the founder of occupational medicine, identified evidence of silicosis in stone cutters. Roughly 200 years later, Dr. Alice Hamilton, a physician whose work resulted in significant safety and health reforms, documented silica related illnesses among granite workers.

GPES is an international technical cooperation programme designed to assist countries in their action to prevent silicosis and eliminate it as an occupational health problem worldwide. Through GPES, the ILO and WHO have shaped a policy perspective for a wide international collaboration in this area between developed countries, developing countries and international organizations.
#0183;#32;Crystalline silica is considered as one of the most common and serious occupational hazards to workers health. Although its association with lung cancer has been studied for many decades, the conclusion remains somewhat controversial. Our objectives are to review and summarize the epidemiological evidence on the relationship between occupational silica exposure and risk of lung

#0183;#32;Silica and asbestos are recognized lung carcinogens. However, their role in carcinogenesis at other organs is less clear. Clearance of inhaled silica particles and asbestos fibers from the lungs may lead to translocation to sites such as the bladder where they may initiate carcinogenesis. We used data from a Canadian populationbased casecontrol study to evaluate the associations between
#0183;#32;Crystalline silica is a common mineral found in the earth''s crust. Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone. Respirable crystalline silica very small particles at
(2000) on the exposure to crystalline silica dust showed that the concentration of crystalline silica in the coremaking unit was mg/m 3, which is lower than the limit, but in other units (molding, cleaning, melting) it was higher than the standard limits specified by the National Institute for Occupational Safety and Health (NIOSH) and ACGIH (Koo et al., 2000).
Occupational Knowledge International (OK International) is a nonprofit organization dedicated to improving public health through innovative strategies to reduce exposures to industrial pollutants. We seek to address inequities in environmental standards between developed and developing countries by working in partnership with industry, government and nongovernmental organizations (NGOs).
