Accuracy, Precision, and Detection Limits — Analytical cost, accuracy, precision, and detection limits are the four main evaluation criteria for selecting an analytical method. Detection limit information will not be givdn here, as it is easily obtained from the literature or from instrument manufacturers. The analysis of NBS orchard leaves and bovine liver is often used to demonstrate the accuracy and precision of ICP analysis. We feel that the analysis of United States Geological Survey (USGS) and Canadian Centre for Mineral Energy Technology (CANMET) standard rocks, is a more rigorous test of ICP analytical accuracy because of the resistance to sample...

By 2002, there were about 1 billion cell phones in use throughout the world. By 2005, experts estimated that about 500 million unused cell phones were stuck in drawers and closets for storage. According to experts at the United States Geological Survey (USGS), the earth science branch of the federal government, these discarded cell phones are a treasure trove of valuable metals waiting to be recycled. 

The United States Geological Survey (USGS) has provided extensive reviews on the distribution, trends, and governing factors on pesticides in groundwater and in surface water (Barbash and Resek, 1996 Larson et al, 1997 USGS, 2006). These reviews included data on several triazines and chlorotriazine metabolites and are helpful in understanding the environmental fate of triazines within the hydrologic cycle in the Midwestern United States.

A number of major studies to analyze triazine herbicides and their degradation products (i.e., metabolites) in water have been carried out by the United States Geological Survey (USGS), Water Resources Division, in the Toxic Substances Hydrology Program. These studies investigated four major water resources - groundwater, surface water, reservoirs, and precipitation.
