Potential impact of engineered nanomaterials release into environment

Engineered nanomaterials (ENMs) are defined as a materials with at least one dimension between 1 nm to 100 nm. They have large surface area and specific electronic, optoelectronic, thermal and catalytic properties in comparison to their bulk counterparts, which make them particularly useful. ENMs that are found in different products (paints, cosmetics, medicines, food, sun tan lotions, remediation treatments, etc.) are usually designed to achieve desired properties. Those materials can be released into the environment throughout their entire life cycle and their extensive usage nowdays could led to their accumulation into environment. Over the last twenty years, ENMs have significantly increased in quantity produced, thus their presence in environment could have significant impact. However, understanding the effects that engineered nanomaterials (ENMs) have on environment through these applications is still limited. The aim of this paper is to point out issues releated to release of ENMs into the environment
