Abstract
21st century brings out a revolution in a field of nanotechnology. Multiple technological applications on nanoscale can be created, manipulated or utilized according to ones need. Engineered Nano materials (ENM) have a lot of benefits and implementation in different fields. Different materials can be used to create an ENM for different purposes. These materials show different physical and chemical properties (Schmid et al., 2010). Although ENM has wide range of applications, but during its manufacturing and usage the chances of vulnerability for the workers and their future effects cannot be anticipated (Cordier & Stewart, 2014). Previous finding showed a group of patients were exposed to nanoparticles which were having a coating of polyacryl paint. The exposed workers showed peculiar symptoms like pleural effusions, progressive pulmonary fibrosis and can lead to death. At that time the reason for the death and symptoms was not clear. Researchers gave different opinions few argued that this is due to gas or raw materials whereas others had different reasons. But after examining biopsies and chest fluids of the patients with Transmission Electron Microscopy and Energy Dispersive X-rays (EDX) nanomaterials were found to be the reason (Song et al., 2011). Nanomaterials showed deleterious effects on human lungs. It was expected that by the end 2020, 6 million workers can be affected by ENMs, thus major guidelines must be follow to avoid the toxic effects of ENMs. (Roco, 2011).
