Teijon, Gloria published the artcileOccurrence of emerging contaminants, priority substances (2008/105/CE) and heavy metals in treated wastewater and groundwater at Depurbaix facility (Barcelona, Spain), Quality Control of 117-96-4, the main research area is emerging contaminant priority substance heavy metal treated wastewater groundwater.
The presence of 170 pharmaceuticals, personal care products, priority substances according to the 2008/105EU Directive and 4 metals (Cd, Ni, Hg, Pb) were studied at the Llobregat delta, south of Barcelona, Spain. In the area, reclaimed water is destined to satisfy environmental uses, irrigation and the construction of a hydraulic barrier against seawater intrusion in the deep aquifer of the delta. A monitoring survey was undertaken of water samples from a tertiary wastewater treatment plant (Depurbaix), treated wastewater with an addnl. treatment of ultrafiltration, reverse osmosis, and UV disinfection (WWATP, for the hydraulic barrier injection). Groundwater samples from the aquifer receiving recharge were also studied. The pharmaceutical group of substances was detected in sampled waters at concentrations rarely exceeding a few μg/L, among the compounds Caffeine, Nicotine and Galaxolide (musk fragrance) were present in >60% of the samples. Diuron was the only priority substance detected. The 4 metals were always present in a variable concentration After the WWATP treatment the majority of analytes are removed from tertiary treated wastewater or their concentration is reduced to <0.1 μg/L. Monitoring revealed a widespread occurrence of analyzed compounds in groundwater. Among them Codeine (analgesic), Ibuprofen (anti-inflammatory), Iopamidol, Iopromide (contrast agent) and Paraxanthine (metabolite of caffeine) have only been detected in groundwater, and are not present in water currently being injected in the deep aquifer. Science of the Total Environment published new progress about Cosmetics and Personal care products. 117-96-4 belongs to class isoquinoline, name is Diatrizoic Acid, and the molecular formula is C11H9I3N2O4, Quality Control of 117-96-4.
