LEVEL1B
A six-compartment Level I program, similar to LEVEL1A.
LEVEL2A
A four-compartment Level II program that prompts for the same information as
Level I programs, but also for reaction and advection rate data.
LEVEL2B
A six-compartment Level II program, similar to LEVEL2A.
LEVEL3A
A four-compartment Level III program that requires all the Level II data and
prompts for D values in the form of transfer half-lives.
LEVEL3B
A six-compartment Level III program, similar to
values directly.
The following Windows models are available:

The DOS-based Generic model contains all the Level I, II, and III calculations.
It is described in a paper by Mackay et al. (1992). It is also described in Chapter 1
of the five-volume Illustrated Handbook of Physical Chemical Properties and Environmental
Fate of Organic Chemicals, by Mackay, Shiu, and Ma, which is also
available in CD ROM format.
The EQC (EQuilibrium Criterion) model is described in a series of papers by
Mackay et al. (1996). It applies to a 100,000 km2
land area (about the size of Ohio).
It is a Windows model and has been used in several assessments of the likely behavior
of a chemical in an evaluative context. An example is the application to the chlorobenzenes
in Ontario by MacLeod and Mackay (1999). Booty and Wong (1996)
have also applied the model to the same region for a variety of chemicals.
The Level III ChemCAN model is in Windows format and contains databases of
24 regions of Canada and a number of chemicals. It can be applied to other regions,
and it has been modified to apply to regions of France (Devillers and Bintein, 1995),
Germany (Berding et al., 2000), and the U.K.
The CalTOX model of McKone, which is available from the California Environmental
Protection Agency (http://www.dtsc.ca.gov/sppt/herd/), is a Level III model that
