CE-UV/LIF Analysis of Organic Fluorescent Dyes for Detection of Nanoplastics in Water Quality Testing

environmental studies that assessed the abundance of microplastics in different water columns [8].Release of nanoplastics from drinking water bottles was characterized by SEM, XPS, SPES and µ-Raman Analysis [9].Spherical organic nanoparticles from bottled water were collected effectively through a tangential flow ultrafiltration system [10].Polyethylene terephthalate nanoplastics collected from commercially bottled drinking water were detected with an average mean size of 88 nm; their concentration was estimated to be 10 8 particles/mL by nanoparticle tracking analysis [11].A new study has reported the levels of micro-and nano-particles released in carbonated beverage bottles range from 68 to 4.7×10 8 particles/L, potentially posing health risks to humans.Polypropylene bottles released more particles than polyethylene terephthalate and polyethylene bottles [12].The occurrence of micro-and nano-plastics (with particle diameters from 0.7 to 20 μm) in plastic bottled water has been assessed, and the median concentration was 359 ng L -1 .Polyethylene was the most detected polymer, while polyethylene terephthalate was found at the highest concentrations [13].The content of microplastic and nanoplastic particles in raw water, tap water, and drinking water was analyzed.Plastic particles were found in all water samples, with an average abundance ranging from 204 to 336 particles/L in raw water, from 22 to 33 particles/L in tap water, and from 25 to 73 particles/L in drinking water [14].
