Sensitive detection of toxic substances in water via computer-assisted digital image analysis
The bbe DaphTox II observes daphnids, commonly known as “water fleas”, under the influence of constantly running sample water. Based on the Extended Dynamic Daphnia Test, bbe developed a new sensitive method to detect hazardous compounds in water from rivers (source-water protection), plants, distribution systems and production drains to preserve human health and to monitor water.
An instrument for the fast and sensitive detection of toxic substances in water
The bbe Algae Toximeter continuously monitors water for the presence of toxic substances. Standardized algae are mixed with the sample water and the instrument detects the photosynthetic activity of the algae. Damage to the algae, caused e.g. by herbicides, causes a reduction in algae activity and activates an alarm above a pre-defined threshold.
An instrument for chlorophyll and photosynthetic activity measurement in the laboratory
The bbe Fish Toximeter observes the behavior of fish in a tank under the influence of a stream of “sample” water with the aid of a camera and continuous computer-assisted image analysis. This uncomplicated but highly sensitive instrument is designed to detect toxic substances in e.g. rivers, reservoirs, water supply systems, water treatment plant intakes and sewers.
