Curricula for Environmental Chemistry have become established, not only recently in the US, but also in European countries. This article discusses the current situation in Germany. German students can make their choice among four possibilities: 1. full-time studies in environmental sciences, 2. classical chemistry program followed by an environmental supplementary program, 3. classical chemistry program with a mandatory choice between environmental or ecological chemistry, 4. classical introductory chemistry followed by a major course of studies in environmental subjects.The background of this development is the attempt to reform the German chemical curricula (Würzburger Modell) which emphasizes practice and the environmetally related subjects.

Material Flow Analysis (MFA) has become an important instrument in environmental science and pollution research. In this paper, we look at the MFA problem as a particularly structured system identification problem. Special emphasis is given to the linear, static case, where we describe a procedure for reconciliating the flow measurements and for estimating the unmeasured flows and the transfer coefficients by taking into account a priori restrictions such as balance equations.

The effects of environmental policy on trade and social welfare are analyzed in a modified Heckscher-Ohlin framework where pollution is embodied in a good consumed. Utility is non-homothetic to account for changes in the demand for healthy goods when income increases. If the polluting input is used intensively, taxing it alone can cause an increase in the good's level of pollution concentration. Instead, a tax on the polluting input in combination with a subsidy to the non-polluting input can result in Pareto improvement. Contrary to other approaches, an abatement policy does not necessarily have a negative effect on a country's comparative advantage. However, if the country is large, change in terms of trade may cause one country to be made better off at the expense of the other, which suggests that compensatory payments may be required to encourage abatement policies.
