Chemical Composition of Precipitation in the Coastal Environment of India
Bulletin of Environmental Contamination and Toxicology, 2010The present study investigated the chemical composition of precipitation at Comba, Madgaon, South Goa during southwest monsoon. The rainwater samples were collected on event basis during June-September 2008 and were analyzed for pH, major anions F, Cl, NO(3), SO(4)) and cations (Ca, Mg, Na, K, NH(4)).

Sampling and physico-chemical analysis of precipitation: a review
Environmental Pollution, 2002Wet deposition is one of two processes governing the transfer of beneficial and toxic chemicals from the atmosphere on to surfaces. Since the early 1970s, numerous investigators have sampled and analyzed precipitation for their chemical constituents, in the context of "acidic rain" and related atmospheric processes.

The chemical composition of precipitation at cloud levels
Quarterly Journal of the Royal Meteorological Society, 1962AbstractIn an attempt to obtain precipitation samples free from contamination either from industrial sources or from sea spray, samples were collected by an aircraft of the Meteorological Research Flight over Southern England at heights up to 8,500 ft.

chemical characteristics of precipitation at an atlantic station
Water Air and Soil Pollution, 1999Weekly or half-monthly bulk rainwater samples were collected over 3 yr (1993–1995) at Porspoder, an Atlantic station near Brest, France. They were analyzed for 0.08 M HNO3-leachable trace metals Cd, Cu, Fe, Mn, Ni, Pb and Zn by direct electrothermal atomic absorption spectrometry.

Factors affecting the chemical composition of precipitation in Syria
Environmental Science and Pollution Research, 2020Concentrations of the major ions (Ca2+, Mg2+, Na+, K+, NH4+, Cl-, HCO3-, SO42- and NO3-), pH and electrical conductivity (EC) values in the rainwater (RW) samples at 16 stations in Syria were determined for characterizing the principal factors affecting the chemical composition of precipitation (P) in this country. Collection of the RW samples was made

Sulfide removal in petroleum refinery wastewater by chemical precipitation
Journal of Hazardous Materials, 2008Sulfide removal by chemical precipitation from petroleum refinery wastewater was investigated. The wastewater samples were taken from the flocculation pond influent of TUPRAS Kirikkale Middle Anatolia Petroleum Refinery Wastewater Treatment Plant (WWTP) and physicochemical treatments using conventional coagulants which were partial precipitant [FeCl(3)
