Photocopiers are indispensable in today's working environment. However, photocopiers emit a number of harmful chemicals during their operation. Photocopier toners also contain a number of potentially toxic substances. Chronic exposure to these substances may compromise the health of photocopier operators. This study is aimed to understand if chronic exposure to photocopier emissions is harmful to human health.
