1. Evaluation of microbial health risks associated with the reuse of source-separated humna urine
Abstract : Human excreta contain plant nutrients and have the potentialto be used as a fertiliser in agriculture. Urine contributesthe major proportion of the nutrients (N, P and K) in domesticwastewater whereas faeces contribute a smaller amount andinvolves greater health risks if reused due to the possiblepresence of enteric pathogens.

2. Microbial Risks in Surface Water Sources
Abstract : Microbial risks need to be properly handled for the provision of healthy drinking water. The mitigation of pathogens in the water source lowers the risk for infection associated with nominal and suboptimal drinking water treatment. READ MORE

3. Development of a Risk-Based Decision Model for Prioritizing Microbial Risk Mitigation Measures in Drinking Water Systems
Abstract : Risk management of drinking water systems is crucial since our society relies on these systems to be robust and sustainable to supply safe drinking water now and to future generations. Pathogens may spread in drinking water systems and cause waterborne outbreaks resulting in human suffering and large costs to the society. READ MORE

4. Effects of heavy metal contamination on carbon and nitrogen cycling : An ecological approach to assess risks to soil functions
Abstract : Soil contamination with heavy metals may disrupt soil microorganisms with important roles in carbon (C) and nitrogen (N) cycling. However, there is a lack of understanding on how microorganisms are affected in soil, which may lead to a mismatch when assessing risks of contaminants to field soils. READ MORE

5. Investigations of the microbial diversity and dynamics in activated sludge using molecular methods
Abstract : Wastewater treatment is necessary to reduce the health risks and environmental impacts associated with discharge of untreated wastewater. The most common way to treat wastewater in wastewater treatment plants is through the activated sludge process. READ MORE
