The commerci简介:Introduction
This dictionary contains terms used in the fields of environmental engineering and
environmental science, and the definitions provided relate to their use in an environmental
context only.
The commercial terms represent company brand names or trademarks, and have
been italicized to differentiate them from the technical terms in general usage.
Whenever appropriate, the use of ™ or
®
has been included following the name of
the entry, although terms may be registered trademarks even though they do not
include either symbol. It is also possible that some of the entries listed as trademarks
may not be registered or properly used by the manufacturers listed in connection
with them.
Brand names and trademarks often evolve and take different forms. Variations
in the use of capitalization, hyphens, or symbols often occur over time. The representation
of the words included in this book reflects the latest version seen in use
and are assumed to be the preferred form.
Commercial acronyms are included if they are registered trademarks or commonly
used abbreviations of company names. Nonregistered product model numbers
and trademarks that are the same as the name of a company are not always included.
Many definitions were extrapolated from stories, advertisements, or product brochures
and were not directly corroborated by the company listed as being responsible
for the term.
The company name included in the definition of a commercial term usually
represents the company that manufactures that particular product or process. In some
cases, the listed company may only market, distribute, or license the product.
In several instances, the same brand name has been listed more than once to
describe different products or processes from different companies. The author is
unaware of any dispute involving these cases and is simply reporting that the
companies identified have used the term for the product described. In some cases,
the term may be dormant, obsolete, or no longer available from the company listed.
Company addresses, phone numbers, and e-mail addresses listed in the Manufacturer’s
Directory were confirmed over a period of several years. Some contact
information may have changed, especially with the recent telephone area code
changes in many parts of the U.S. Readers are cautioned that an incorrect phone
number, address, or e-mail address does not mean that a company is no longer in
business.
There are a few cases where a company whose name is listed in a definition is
not included in the Manufacturer’s Directory. If current contact information for a
company could not be located, the out-of-date information was not included.
Terms have been arranged alphabetically using current word processing software.
In general, terms related to plumbing, household products, computer programs,
or software have not been included.
All of the terms have been listed in good faith. A reasonable attempt has been
made to confirm all definitions and, in the case of commercial terms, verify the
companies responsible for the listings. The author apologizes for any omissions or
errors.
