21st century is a period that human society carrying out industrialization. One of the most popular materials, plastics, is a kind of artificial materials that satisfying humans’ needs in improving living standards. Unfortunately, there are some matters derived from the plastic products, which are microplastics, and they would be derived from the daily usage in Therefore, the microplastics can be possibly contaminate the household environment once the household owners use plastic products. Through the analysis of the indoor dust, the Indoor environmental pollutants would then be investigated, and further deduce how the pollutants released from the indoor materials and activities (Mercier et al., 2011). In indoor dusts, one of the major sources of microplastics is textile washing (Liu et al., 2019). In nowadays, some of the clothes are made of artificial plastic-blending cotton or simply plastics, therefore microplastics would be possibly derived during process of laundry. Polycarbonate (PC) and Polyethylene terephthalate (PET) are the popular microplastics in indoor dusts (Liu et al., 2019). Apart from microplastics, heavy metals are also one of the major contaminants to household, which also could be investigated by analyzing the household dust. Heavy metals from outdoor would be potentially contaminate household indoor environment through airborne dust. Also, heavy metals may cause health risks to humans if humans expose to those heavy metal in their lifetime. In this project, the investigation of indoor household pollution of heavy metals and microplastics in Hong Kong families would be done. Also, the investigation that has been mentioned before would be compared to the relations of habit of using plastic products in Hong Kong families, the location of the household. For this project, it includes experimental design and literature research, so as to figure out the indoor microplastics & heavy metals pollution with the relation of the usage of plastics in Hong Kong families and the location of household.
