Microbial transformations and biological effects of fungicide-derived benzothiazoles determined in industrial wastewater
Article Abstract:
The degradation of the fungicide 2-(thiocyanomethylthio)benzothiazoles (TCMTB) and the biological effects of its degradation products were investigated in tannery wastewater. The TCMTB degradation products 2-(methylthio)benzothiazole, benzothiazole and 2-mercaptobenzothiazole were incompletely removed by aerobic and anaerobic wastewater treatment. Moreover, they were shown to inhibit nitrification, respiration measured as biological oxygen demand and luminescence in the aquatic organism Vibrio fischeri. Their potential toxicity and biological stability make 2-substituted benzothiazoles important environmental pollutants.

Drinking recycled wastewater
Article Abstract:
The dwindling number of groundwater resources due to unchecked population growth and rapid industrialization has forced researchers to use the artificial groundwater recharge technique. Under this technique, treated city wastewater is injected directly into aquifers or into the ground to infiltrate the surface. However, other researchers believe that this practice could jeopradize public health since only a fraction of the contaminants present in the wastewater can be identified. This argument has led to the filing of lawsuits in places where groundwater recharging is prevalent.

Surface tension of wastewater samples measured by the drop volume method
Article Abstract:
The drop volume technique was used to measure the surface tension of samples of wastewater taken from sewage treatment plants near Zurich, Switzerland. This simple technique produces accurate and reproducible results, as long as wastewater samples are stabilized between sampling and measurement. Other rules that should be followed include chilling the samples near zero degrees Celsius and conducting a preliminary standard method experiment.
