Soil tests that determine fertilizer needs measure nitrate in the soil, but they don
Bacteria can become resistant to antibiotics. And waste water effluent from sewage treatment plants can play a significant role in this process. This is concluded by UK researchers who published their new findings in the Journal of Antimicrobial Chemotherapy.
The researchers took river sediment samples, downstream and upstream of a UK waste water treatment plant in 2009 and 2011. They looked specifically at E. coli bacteria and their resistance against third-generation cephalosporins. This is an important groups of antibiotics, used to treat humans with blood poisoning and brain infections for example.
It was shown that the water after treatment contained seven times more resistant E. coli bacteria than the waste water before it was treated. According to the researchers this is because the sewage treatment plants are a

The OXY Zirconia analysers, from DRM Technic, use modern technical solutions to provide high quality and affordable analysers.
Designed to measure continuous Oxygen in combustion & process applications for environmental reporting,
process control or performance and quality purposes. The standard configuration uses a built-in control panel,
however this can be mounted separately to the probe if required.
OXY analysers utilise the Zirconia cell measurement method that provides the highest quality measurements for combustion processes in Large Combustion Boilers, Furnaces and reference level emissions monitoring.
Features include: a range of 0-25% Oxygen, accuracy of +/- 2% of the range, a maximum working temperature of 600C, and probes up to 2 meters long.
Accesories: Additional Calculating Module for continuous calculation of combustion parameters
(excess air, efficiency, CO2 and process temperature), a Calibration Panel for calibrationing the OXY analysers, with calibration and air reference gas connections, Process Connection Flange Adaptors, Pipe Mounting Flanges and Protection Tubes
