Removal of strontium from drinking water by conventional treatment and lime softening in bench-scale studies.
The United States Environmental Protection Agency Contaminant Candidate List 3 lists strontium as a contaminant for potential regulatory consideration in drinking water. Very limited data is available on strontium removal from drinking water and as a result, there is an immediate need for treatment information. The objective of this work is to evaluate the effectiveness of coagulation/filtratio...
متن کاملSynthetic musk fragrances in Lake Michigan.
Synthetic musk fragrances are added to a wide variety of personal care and household products and are present in treated wastewater effluent. Here we report for the first time ambient air and water measurements of six polycyclic musks (AHTN, HHCB, ATII, ADBI, AHMI, and DPMI) and two nitro musks (musk xylene and musk ketone) in North America. The compounds were measured in the air and water of L...
متن کاملReuse of water treatment residuals from lime softening, Part I: Applications for the reuse of lime sludge from water softening
Lime sludge, an inert material mostly composed of calcium carbonate, is the result of softening hard water before distribution as drinking water. A large city such as Des Moines, Iowa, produces about 32 000 tons of lime sludge (dry-weight basis) annually. This is about half of the lime sludge produced in Iowa per year in eight different cities, and these cities currently have 371 800 tons (dry-...
متن کاملSynthetic musk fragrances in human milk from the United States.
Synthetic musk compounds are used as additives in many consumer products, including perfumes, deodorants, and detergents. Earlier studies have reported the occurrence of synthetic musks in environmental and wildlife samples collected in the United States. In this study, human breast milk samples collected from Massachusetts, were analyzed for the determination of concentrations of synthetic mus...
متن کاملThe toxicology of musk fragrances
Synthetic musk fragrances are widely used as replacements for natural musks not only in perfumes but also in soaps, toiletries and disinfectants. The worldwide annual production of musk fragrances ranges between 6000 and 8000 metric tons per year, of which nitroand polycyclic musks represent 30 and 70%, respectively. As a result of their inherently low biodegradability, nitroand polycyclic musk...
