This article highlights the benefits of guanidinoacetic acid (GAA) supplementation in swine production. GAA, an essential component for efficient energy metabolism, plays a crucial role in pig nutrition. While pigs can produce part of their GAA requirement, the remainder needs to be supplied...

This paper presents the case-study of a school with an acute air pollutant release and unspecific complaints of pupils (existing for a longer period of time). It is shown the handling of the related questions, investigations (laboratory and medically) and further evaluations of the indoor hygiene...

Background: Ambient air pollution from motor vehicle traffic is recognized to pose serious health risks to the population. However, it is important to consider the contributions of the individual pollutants as well as of the mixture as a whole in order to come to the right conclusions and measures. ...

In arable farming areas, groundwater contamination by pesticides is frequently found. To investigate direct causal relationships with individual management measures, the outlets of pipe drainage systems were sampled weekly over seven months at eight different arable fields in...

Perfluorinated and polyfluorinated alkyl substances (PFASs) are found in a large number of chemicals and can be harmful to humans and the environment. With the use of mass spectrometry (HRMS), it has recently been possible to detect about 60 substances that have not been investigated at all or have ...

Aquifer heterogeneity complicates the prediction of plume behaviour. At a representative PAH-contaminated site, we developed a procedure to check the potential of monitored natural attenuation (MNA) in a heterogeneous aquifer with uniform mean velocity. The site is located in an urban district of...

Often, nitrate in groundwater is attributed to agricultural land use with high nitrate concentrations in the soil. Regulatory measures exclusively address the agricultural sector and the application of fertilisers is increasingly regulated. A systematic study of nitrate levels in the soil together...

This article describes the installation and use of photovoltaic cells to harness solar power at the SalzburgMilch Keiserei dairy plant in Lamprechtshausen, Salzburg, Austria. This innovation ensures sustainable and environmentally friendly energy production and use in organic dairy farming systems...

Nutrition inputs into surface waters and groundwater pose a risk for human health. For example, high nitrate levels in groundwater impair drinking water production. High nitrate intake is associated with different negative effects on human health. Pollution of bathing waters with nutrition favor...

Undersupply and oversupply of dairy cows with essential trace elements should be avoided from the point of view of animal health and environmental pollution. The aim of the study was to proof the results faecal analyzes on the nutritional supply situation with essential trace elements in...
