Peer reviewedEnvironmental Science and Technology, 1976
The use of remote sensing to quickly detect and efficiently monitor environmental problems is discussed. Available technology, typical operations procedure, and film choice are detailed. (BT)
Descriptors: Air Pollution, Environment, Environmental Influences, Instrumentation
Peer reviewedKehoe, Thomas J. – Environmental Science and Technology, 1977
The instrumental method for detecting total organic carbon (TOC) in water samples is detailed. The method's limitations are discussed and certain precautions that must be taken are emphasized. The subject of TOC versus COD and BOD is investigated and TOC is determined to be a valid indication of biological demand. (BT)

Peer reviewedInhaber, Herbert – Environmental Science and Technology, 1975
A Canadian scientist discusses his country's environmental monitoring programs (by parameter and medium), points out their strengths and weaknesses, and indicates some possible directions for future efforts in the field of environmental monitoring at both the national and international level. (BT)

Peer reviewedPhillips, Sidney L.; Mack, Dick A. – Environmental Science and Technology, 1975
This discussion gives a general picture of the instrumentation available or being developed for measuring the four major categories of water pollutants: metals, nutrients, pesticides and oxygen demand. The instruments are classified as follows: manually operated laboratory analyzers, automated laboratory instrumentation, manual field monitors, and…

Peer reviewedWalker, John E.; Dahm, Douglas B. – Environmental Science and Technology, 1975
Infrared remote sensors, plus photometric interpretation and digital data analysis are being used to record the stresses on air, water, vegetation and soil. Directly recorded photographic information has been the most effective recording media for remote sensing. (BT)

Peer reviewedArd, R. W., Jr. – Environmental Science and Technology, 1976
The Coast Guard utilizes a number of monitoring detectors, sensors, and techniques to find, recover and identify oil spills. Discussed in this article are in-situ and airborne sensors, systems developed to provide clean-up capability such as air deployable anti-pollution transfer system (ADAPTS), and techniques which will determine the source of a…

Peer reviewedCase, S. K.; And Others – Environmental Science and Technology, 1978
This method of image enchancement and real-time imput of 3-D microscopic objects into an optical pattern recognition system is designed to identify and count diatoms as a means of water pollution assessment. The method consists of directing a low-power laser beam into a microscope to produce a coherent image of the specimen. (Author/BB)
