Determination of Metals by Inductively Coupled Plasma Spectroscopy 1. SCOPE AND APPLICATION: 1.1 This method provides procedures for the determination of dissolved elements in ground waters, surface waters, and drinking water supplies. It may also be used for the determination of total recoverable element concentrations in these waters and wastewaters. Dissolved elements can be determined after suitable filtration and acid preservation. Acid digestion procedures are required prior to the determination of total

the size of the human population, the state and type of industry and agriculture are but a few of the factors contributing to each country’s unique pollution problems. Pollution is discharged either directly into to the sea, or enters the coastal waters through rivers and by atmospheric deposition. In order to mitigate and control the impact of pollution on coastal and marine resources, it is essential that the type and load of pollutants be identified. This involves determination of the sources

learned that we, as a whole, are ruining our water supplies for the future. We have continuously flushed whatever we don’t want to deal with into our sewer systems. The toxins, mostly from cleaning supplies and body treatment products are being reintroduced into our water sources. The waste water treatment facilities are efficient in removing the organic waste from the water supply, but they are not active in removing chemicals, and nutrients from the water table. I would like to discuss a few things
