The emission and physicochemical properties of airborne microplastics and nanoplastics generated during the mechanical recycling of plastic via shredding.

This study examined the emission and physicochemical properties of microplastics and nanoplastics (MPs/NPs) generated during shredding, which is regularly used in mechanical recycling. Waste and new polyethylene terephthalate, polypropylene, and high-density polyethylene were investigated herein for a total of six categories. The concentration and size distribution of particles were measured using two spectrometer instruments, and morphology and elemental composition of emitted particles were analyzed with microscopy and spectroscopy.

Living in poverty and its effects on health.

Poverty has been identified as the greatest threat to health. Generally speaking, poor people are sick more often than wealthier people, and poor people die younger due to poorer economic, social, political and physical conditions. The article explains the difference between relative poverty and absolute poverty, before going on to explore various reasons why people living in relative poverty are more susceptible to ill health than their wealthier counterparts.
