Instructions to Authors Main Page

All nonstandard abbreviations should be defined in the text at first use; for example, organochlorine (OC) pesticides, LOD (limit of detection), polymerase chain reaction (PCR). Abbreviations for elements (e.g., Fe, Cu) and chemical compounds (e.g., polychlorinated biphenyls, PCBs; carbon dioxide, CO2)) should be spelled out on first use and abbreviated thereafter.

The standard abbreviations listed below do not need to be defined in the text. Note that units of measure should be abbreviated only when a specific amount is given (e.g., "concentration of 10 ng/mL" versus "units of nanograms per milliliter").
