ToxSys_DaphII
Daphnia
Toximeter
|
| The
Daphnia Toximeter continuously records and analyses the movement
of daphnia in the instrument chamber where they are under
the influence of “source” or “test” water.
The instrument's toxicity computation is based upon the statistical
deviation of the various measured Daphnia behavioral parameters
from the (user-defined) norm. This unique instrument has no
counterpart in the world |

|
| The
bbe Daphnia Toximeter assesses behaviour as below: |

| Application |
bbe Toximeters provide a highly sensitive biological system for early
detection of potentially dangerous unknown substances, in a wide variety
of circumstances. These instruments are ideal for detecting water
quality contamination in real-time to protect both plant and animal
life. The Toximeters provide a means to detect (and alert users to)
potentially dangerous circumstances. Based on the alert, the user
may then take appropriate measures including further chemical analysis,
water source diversion, process suspension or further treatment. Expensive
chemical analysis can be targeted to key toxic events with potentially
significant cost savings. Some examples of applications for our Toximeters
include:
- environmental
monitoring, including ports, lakes, reservoirs and dams
- source/ground
water monitoring, supply monitoring and intake monitoring
- surface water
monitoring including rivers and lakes, measuring stations and
early warning systems
- pre-treatment
assessment
- post-treatment
quality control
