Air pollution due to fine particulates (PM2.5) is globally increasing the relative risk of mortality from cerebrovascular disease, lung cancers, and chronic respiratory diseases. However, an emerging challenge is to understand the relationship between active components of PM2.5 and human health. Polycyclic aromatic hydrocarbons (PAHs) was considered as an essential toxic component of PM2.5. With the increase of atmospheric oxidizing capacity, more derivatives of PAHs such as nitrated PAH...

Phosphorus is an essential nutrient for all lives. Phosphorus is involved in the process of material and energy transmission and storage in the biological organisms. Phosphorus exists in the phospholipid bilayer, which forms the basic skeleton of cell membrane. It is also an important component of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), which are used by living organisms to reproduce and function in everyday life.
The flow of phosphorus in nature is a one-way flow, st...
