Solution Overview
Early warning and assessment of sudden water contamination events face challenges due to the complex interactions of pollutants, which may exhibit additive, synergistic, or antagonistic effects. Conventional physicochemical parameter monitoring lacks the capability to evaluate these combined toxic impacts. Comprehensive bio-toxicity testing addresses this gap by detecting the latent toxic effects of unmonitored contaminants, providing critical insights into their holistic risks to human health and ecosystems. This approach plays a vital role in safeguarding water supply security, environmental emergency response, and public health crises. 
In alignment with China’s Guidelines for Ecological Environmental Emergency Monitoring Capacity Building (issued by the Ministry of Ecology and Environment on November 9, 2020), which mandates enhanced emergency monitoring capabilities—including equipment such as bio-toxicity analyzers—to address dual environmental incidents, Huaju Scientific Instruments has developed a tailored solution for rapid on-site toxicity screening.
ShenZhen Huaju Scientific Instruments BM-60 Portable Water Bio-Toxicity Analyzer
Designed for ecological emergency management, water source protection, pollution source screening, and educational demonstrations, the BM-60 surpasses standard bio-toxicity detection requirements with its advanced features:
1. Innovative Detection Principle
Utilizes luminescent bacteria (Photobacterium phosphoreum strains 502 and T3) as bio-sensors.
Healthy bacteria emit 450–490 nm blue-green fluorescence during metabolism. Toxins inhibit this luminescence, with suppression levels correlating to pollutant toxicity.
Dual-optical-path reference detection technology enables dynamic monitoring of toxicity inhibition, capturing real-time reaction kinetics for comprehensive assessment.
2. Key Features
Rapid detection: Results in as fast as 5 minutes.
Broad detection range: Identifies heavy metals, pesticides, organic/inorganic toxins.
Portable design: Includes pre-packaged test tubes, pipettes, reagent kits, and a carry case.
Long battery life: Built-in lithium battery supports >20 hours of field operation.
User-friendly interface: Color LCD displays inhibition rate, luminescence intensity, and kinetic curves; no specialized expertise required.
3. Technical Advantages
High sensitivity and stability: Freeze-dried bacteria ensure reliable, contamination-free performance.
Applications
Environmental agencies: Emergency water quality assessment.
Water supply utilities: Source water and pipeline monitoring.
Pollution control: Rapid on-site screening of industrial discharges.
Academia and research: Educational demonstrations and toxicity studies.
