Pharmaceuticals and personal care products (PPCPs) are a group of emerging micro-pollutants causing detrimental effects on living organisms even at low doses. Previous investigations have confirmed the presence PPCPs in environment hazardous levels, mainly due to inefficiency conventional wastewater treatment plants (CWWTPs). Their stable structure induces longer persistence environment. Microa...
The following were the identified and defined classes of emerging contaminants concern (ECCs): pharmaceutical personal care products (PPCPs), perfluorinated compounds (PFCs), plasticizers, agrochemicals, industrial additives agents (IAAs), flame retardants (FRs), Nanopar-ticles (NPs), steroids hormones, gasoline additives. From 1983 to 1990, an estimated 15,000 metric tons pesticides reported h...
Many pharmaceuticals and personal care products (PPCPs) are commonly found in biosolids and effluents from wastewater treatment plants. Land application of these biosolids and the reclamation of treated wastewater can transfer those PPCPs into the terrestrial and aquatic environments, giving rise to potential accumulation in plants. In this work, a greenhouse experiment was used to study the up...
The presence of bioactive trace pollutants such as pharmaceuticals and ingredients of personal care products (PPCPs) in different environmental compartments (rivers, lakes, groundwaters, sediments, etc.) is an emerging issue due to the lack of existing information about the potential impact associated with their occurrence, fate and ecotoxicological effects. Due to the low PPCP concentrations r...
The worldwide overuse of pharmaceuticals and personal care products (PPCPs) has introduced these compounds in exorbitant amounts into aquatic systems. Pharmaceuticals particular have been highlighted among other water contaminants not only due to their significant consumption continuous discharges environments, but also manufacturing processes.
Adsorption of typical pharmaceuticals and personal care products (PPCPs) (such as naproxen, ibuprofen and oxybenzone) from aqueous solutions was studied by using the highly porous metal-organic framework (MOF) MIL-101 with and without functionalization. Adsorption results showed that MIL-101s with H-donor functional groups such as -OH and -NH2 were very effective for naproxen adsorption, despit...
Municipal effluents are important source of contaminants including many socalled Pharmaceutical and Personal Care Products (PPCPs) substances, whose potential impacts on the receiving environment are poorly understood. New emerging substances, in the form of pharmaceutical drugs like antibiotics, antiinflammatory, and anti-convulsive, are now being frequently measured in these wastewaters. Whil...
A screening of metals, persistent organic pollutants, pharmaceuticals and personal care products (PPCPs), and other organic contaminants in sludge from seven Swedish sewage treatment plants (STPs) was performed in this study. This extensive screening provides information on mass flows of 282 compounds used in the Swedish society to sewage sludge. It reveals constant relative contaminant concent...
