Groundwater Remediation Using Biological and Photocatalytic Methods
The degradability of two commercially available pesticides was studied
using heterogeneous photocatalytic and activated sludge treatment
methods. The first pesticide contained 5% quizalofop-P-ethyl as an active
ingredient and petroleum naphtha as a solvent, the latter causing
difficulties both in photocatalytic and biological treatment methods. The
active ingredient of the second compound was acetamiprid. The
photocatalysis proved to be effective both under laboratory conditions
(using UV light) and when exposed to sunlight, but the pesticides remained
stable during the employed biological treatment. Preliminary information on
its behaviour in soil was obtained from transport modelling
International Law in the Service of Minority Protection—Hard Law, Soft Law, and a Little Practice
With the increase in the number of international organizations directly or indirectly involved in
the protection of human rights on the European continent, a kind of competition has developed in
recent decades in the field of fundamental rights: By widening the scope of the rights to be protected
on the one hand, and by expanding the forms of legal remedies for their protection on the other, the
organizations concerned are becoming increasingly integrated into the internal legal systems of the
European states. This is why the shortcomings in the effective, systematic protection of minority
rights in Europe are quite obvious. It is therefore a contradictory area of law, which must be exam-
ined in the light of the potential and the obvious weaknesses of the existing norms and monitoring
systems of minority rights. There are tensions and contradictions at many points between the typi-
cally individualistic constitutional systems of our time and the concept of minority rights today. It
is also clear, however, that it is precisely the highly developed fundamental rights systems that are
expected to protect the rights of minorities. The history of the development of minority rights protec-
tion, which has its roots in the distant past, provides ample examples of mistakes to be avoided and of
the details to which particular attention should be paid in the course of regulation
