Coating zirconium oxide-nanocomposite with humic acid for recovery of mercury and chromium in hazardous waste of chemical oxygen demand test

Implication of nanotechnology to reduce the environmental risks of waste associated with the COVID-19 pandemic

“…Lai et al 39 show that wearing a mask increases the danger of breathing microplastics, particularly microfibers. 39 One should also consider inhaling microplastic from the air to protect human health.…”

“…In this situation, masks serving as a barrier may help to minimize the amount of microplastic inhaled while breathing. 40 Lai et al 39 proposed that even when masks are worn continuously for 720 hours, they greatly reduce the risk of breathing particles. Tables 2 and 3 show the total quantity of fiber-like microplastics and particles observed collected throughout the 720 hours breathing simulation test while wearing various types of masks.…”

“…Abbasi et al 38 detected 900 microplastics and 250 microrubbers of various sizes and shapes in 15 g of street dust collected in Iran. 38 Lai et al 39 show that wearing a mask increases the danger of breathing microplastics, particularly microbers. 39 One should also consider inhaling microplastic from the air to protect human health.…”
