Answer in detail as 10 marker.
Solution
There has been an increasing production and use of nanomaterials lately. This raises concerns about their potential toxic effects on human health and the environment.
There is high variation among different nanoparticles in their ability to cause toxic effects.
Example 1
CuO nanoparticles
They show severe cytotoxicity and DNA damage. These particles also caused oxidative lesions and can lead to an increase in the ROS. The ROS are also called reactive oxygen species and are usually formed in relation to any kind of stress faced by the organism. Thus CuO poses to be quite toxic as DNA damage can often lead to mutations and this could then cause cancer, or even birth defects in progeny.
Example 2
ZnO shows toxic effects on cell viability as well as DNA damage. Since cell viability is impacted, exposure can not only harm the DNA and future cells or progeny, but also cause harm to existing cells. These particles can lead to cancers, and other mutational defects.
