Ainul Huq, 55, (R) and Bulbul Hossain, 25, describe the condition of their lungs inside a village house in Burimari in Lalmonirhat district, Bangladesh July 9, 2013. According to Huq and Hossain, they are sufferers of silicosis, an incurable lung disease caused by inhalation of silica dust as they used to work in a stone crushing factory. The stone crushing industry in the Burimari land port area of Lalmonirhat, in the north of Bangladesh, produces lime powder for various industrial purposes. According to a report by the Bangladesh Institute of Labour Studies, those working in the industry run the risk of contracting silicosis. A researcher from the organization said that at least 18 workers in the Burimari area had died of complex silicosis over the last four years. International attention has been focused on workers' safety in Bangladesh since the disaster at Rana Plaza, a garment factory complex which collapsed in April, killing 1,132 workers.
