**6. Conclusions**

Microplastics demonstrate much more challenging to remove due to their small size and huge quantity, which can be remain active for years. The small particles of microplastics serve as carriers for bacteria and persistent organic pollutants, which are considered as biodegradable materials. Moreover, they consist of chemical materials that are hazardous to human and animal health in high concentrations. Many sources of food and landfill have microplastic waste that goes directly or indirectly to the human body by eating food or breathing air, which affect human health. It was found that the human person eats at least 50,000 microplastic particles every year. Still, there is not enough data that help to know how microplastics affect humans. However, there are some solutions to eliminate the effect of microplastics on the humans and animals. Therefore, it is very important to make more researches to develop new standardization methods to analyze microplastics and determine their effect and risk on the human body.
