Health and environmental issues
The shelling of cashew nuts has deleterious effects on worker health and the environment as seen above in Processes. CNSL is harmful to the skin, the smoke pollutes the atmosphere and the wastewater contaminates soil and water. In India, the installation of cashew nut extraction plants is regulated: it is forbidden to build a cashew factory in the vicinity of hospitals, schools, airports and public buildings, and extraction plants must be at a distance of at least 500 m from each other (Sengupta, 2007).
