Biomonitoring Toxicity

Toxicity Monitors On-line and laboratory analysis techniques

Toxicity covers a wide range of possible contaminants, and it is possible for us to measure it with a variety of different techniques. We can use respirometry rates to determine negative effects on life-forms, hence the inclusion of our RespSys system below. bbe-Moldaenke specialise in algal monitors, and have on-line and cuvette systems for algal detection and differentiation.

bbe-Moldaenke also offer specialised Toxicity monitors using live detection by monitoring fish activity, or by monitoring the activity of daphnia. Toxicants of different characteristics such as pesticides, herbicides, chlorinated hydrocarbons, heavy metals etc. can affect a cell’s integrity and membrane function or cell respiration.

Lar Toxicity

A range of biomonitoring toxicity analysers including the NitriTox for detection inhibition to the waste water treatment process and the Tox alarm for drinking and river water applications

bbe Algae Toximeter

The bbe Algae Toximeter provides continuous toxicity measurement because it monitors changes in the fluorescence spectrum and fluorescence kinetics of the algae. Ideally suited to the detection of herbicides and pesticides.

bbe Daphnia Toximeter

Highly sensitive toxicity measurement technique. You can continuously record and analyse the movement of daphnia using Daphnia toxicity monitors. The analyser can be fed with "source" or "test" water. BBE-Moldaenke developed this monitor because daphnia behaviour can be directly linked to toxicity levels and provide an early warning system.

The AlgSys_ALA is a laboratory algal monitor capable of measuring algal activity. As such, you can use it to assess the effects of discharges on the viability of suspended aquatic algae. Ideal for testing potential agrochemical effluents prior to discharge. You can use the cuvette system to allow multiple samples to be collected and analysed as a batch. This might include samples from several sites, or samples from various depths at a single site.

RespSys is a range of respirometers for aerobic or anaerobic applications.
