Volatile synthetic organic chemicals

Case Volatile Synthetic Organic Chemicals. The USEPA recently published recommended maximum contaminant levels (RMCLs) for eight volatile synthetic organic chemicals (43). Seven of these were treated as potential carcinogens in this proposal. Under the U.S. Safe Drinking Water Act (SDWA), the first step in the regulatory process for...

WASP/TOXIWASP/WASTOX. The Water Quality Analysis Simulation Program (WASP, 3)is a generalized finite-difference code designed to accept user-specified kinetic models as subroutines. It can be applied to one, two, and three-dimensional descriptions of water bodies, and process models can be structured to include linear and non-linear kinetics. Two versions of WASP designed specifically for synthetic organic chemicals exist at this time. TOXIWASP (54) was developed at the Athens Environmental Research Laboratory of U.S. E.P.A. WASTOX (55) was developed at HydroQual, with participation from the group responsible for WASP. Both codes include process models for hydrolysis, biolysis, oxidations, volatilization, and photolysis. Both treat sorption/desorption as local equilibria. These codes allow the user to specify either constant or time-variable transport and reaction processes. 

The interaction of synthetic organic chemicals with mobile colloids present in soil solution has been demonstrated (Ballard, 1971). These interactions may alter the environmental behavior and fate of synthetic organic compounds, including toxicity and bioaccumulation, volatility, photolysis, and nonbiological alteration. It has also been proposed that mobile colloids may act as carriers for organic...

There is a standard of performance for equipment leaks of formamide and other volatile organic compounds (VOCs) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOCs, considering costs, nonair quality health and environmental impact and energy requirements.

PCBs are a group of synthetic organic chemicals that can cause a number of different harmful effects. There are no known natural sources of PCBs in the environment. PCBs are either oily liquids or solids and are colorless to light yellow. Some PCBs are volatile and may exist as a vapor in air. They have no known smell or taste. PCBs enter the environment as mixtures containing a variety of individual chlorinated biphenyl components, known as congeners, as well... 

USEP A, Control of Volatile Organic Compound Emissions from Air Oxidation Processes in Synthetic Organic Chemical Manufacturing Industry, PB85-164275. 

The Clean Air Act regulates carbon disulfide for equipment leaks of volatile organic compounds in the synthetic organic chemical manufacturing industry (EPA 1995g). 

Table VI presents the WHO guidelines for bacteriological quality of drinking water. Tables VII, VIII, and IX contain the USEPA standards and WHO Guideline Values for inorganic, volatile organic and synthetic organic chemicals, respectively. Table X and XI presents the USEPA and WHO Guidelines Values for disinfectants and disinfection byproducts. Table XII presents the USEPA limits (secondary standards that are not enforceable at the federal level) and the WHO Guideline Values for constituents affecting the taste and odor of the water.
