Persistence and Spatial Range as Endpoints of an Exposure-Based Assessment of Organic Chemicals

Scheringer, Martin·1996·Environmental Science & Technology

Abstract

An approach to the classification of environmental chemicals in terms of exposure-based quantities is presented. First, the spatial range of environmental chemicals is introduced as the counterpart of the persistence, and mathematical definitions are given for the calculation of both persistence and spatial range from exposure data. Persistence and spatial range serve as proxy measures that reflect the influence of many different transport and degradation mechanisms without the details of these mechanisms being discussed individually. Secondly, a one-dimensional model of the global circulation is set up in analogy to previous unit-world models; besides atmospheric and oceanic long-range transport, the model covers diffusive and nondiffusive phase transfer processes as well as net first-order degradation. CCl 3 F and 1-butanol are used as benchmarks representing long-range/long-term and short-range/short-term exposure. As a first test of the model, the distribution behavior of these two chemicals is quantified in terms of the three spatial ranges of the phases soil, water, and air.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
