Because of the high volatility and nonpersistence of some agents, lack of positive field identification should not be considered proof that agents were not released. Unless the release occurred in an enclosed or confined space, then by the time testing can be undertaken there may not be a detectable level of agent remaining at the scene. 

The previous studies and almost all of the simulated acid rain experiments discussed herein were designed to quickly produce symptoms and obtain threshholds for plant injury. To date there has been no documented field identification of ambient acid rain injury to forest trees or woody plants (8). Among many potential reasons, this may be due either to the fact that ambient acid rain is often accompanied by other atmospheric pollutants, thus injury symptoms are different, or that changes are occurring subtly over time ... 

Chemistry. Chemical analysis methods range all the way from simple to sophisticated. See Chapter 6 under Field Identification. The exact chemical composition is generally not required. The identification method should distinguish the correct material from materials that may have been substituted. For example, a moly (molybdenum) spot test is a chemical color change technique that is sometimes used to distinguish 304 (no moly) from 316 (small percentage of moly) stainless steel. 

Field Identification. Supplemental chemistry verification by x-ray fluoresence spectroscopy or chemical spot test (e.g., for moly in 316 stainless steel) may be required. 

Many types of nondestructive, leak, corrosion evaluation and mechanical tests may be used to establish and verify quality requirements of the materials specification. In addition, identification markings enable materials to be checked for specification conformance. Field identification methods must be used when all else has failed, but their limitations must be understood. 

Field identification provides rapid, nondestructive verification of the composition of metal products before they are fabricated into components, placed in service, or stored for later use. Field identification may be required when accompanying paperwork is lost or identification markings are obliterated or not to be trusted. 

Rapid, on-site analysis for directing detailed sampling regimes and on the spot decisions for soils shift operations. Increased confidence in the transferability of laboratory-validated treatment techniques to the field. Identification of opportunities and constraints for individual techniques under heterogeneous conditions. Improved stakeholder dialogue and involvement in decisions regarding site investigation assessment and remediation. 

One should be very careful with field identification when collecting any mushroom to be eaten. This is especially tme in the present case, to avoid confusing Amanita muscaria or A. pantherina with one of their potentially lethal cousins. The deadly toxins alpha-wssadivA and phalloidin (and related cyclic polypeptides) have... 

LC/MS is penetrating many other scientific research sectors and is becoming widely used by various scientists toxicologists, physicians, environmental scientists, veterinary scientists, and so forth. This becomes more evident in fields where unambiguous identification of banned or toxic substances is required. In clinical and forensic toxicology, LC/MS competes with GC/MS, the working horse of the field. Identification and quantitation of several drugs of... 

Morphological properties, although crucial in identification, depend (as was the case with yeast) on substrate and other conditions of growth. For example, some molds may appear yeastlike when growing under mi-croaerophilic conditions as would be found in bottled juice. The color of the mold colony is frequently used for preliminary field identification of molds.
