The Royal Netherlands Meteorological Institute (KNMI) has published the KNMI’06 climate scenarios in 2006. These scenarios give the possible states of the climate in The Netherlands for the next century. Projections of changes in precipitation were made for a time scale of 1 day. The urban drainage sector is, however, more interested in projections...

The “3R” (reduce, reuse and recycle) principle has been significantly employed in processing ELVs (end-of-life vehicles), particularly ELV parts and methods to promote sustainable development. Motivated by legislation such as Directive (2000/53/EC), recently, ELV problems have seriously been treated in developing countries as well. This paper analy...

Conference Paper
Abstract The use of agrochemicals such as chemical fertilizers and pesticides has caused tremendous harm to the eco-environment. Organic matter (OM) addition to soil often leads to a rapid increase in the activities of various enzymes and reactivation of biogeochemical cycles in soil. One of the major concerns today in all over the world is the pol...

The heavy metals mean serious risk in environmental pollution. Some of them are essential for many organisms in a low concentration, but the others should be toxic at low concentrations, too. The heavy metals are contacted through the food chain with living organisms. Industrial, transport and municipal waste origin effects of contaminants appear m...

The application of municipal sewage sludge (MSS) increases soil organic matter (SOM) and improves soil structure. MSS of high heavy metal (HHM) content significantly decreased soil bioproductivity, reduced its biochemical properties, and lowered the microbial contents in comparison with MSS of low heavy metal (LHM) content. Total alfalfa dry matter...

If soils are to be successfully treated with sewage sludge it is necessary to study the biological properties of the soil, which are closely correlated with soil quality. In general the biocomponents of the soil respond more rapidly to changes in soil conditions than the physical and chemical properties, so the microbe populations in the soil and t...

Water is affected by several diffuse and pointwise of contamination sources, which causes variation in water quality. The observation of the biological components in an aquatic ecosystem is one of the best applied method to follow such, changes, because the biological components often regenerate slower than the contaminated material, in the water....
