Waste Toxicity Testing

Waste Toxicity Testing

Hazardous wastes refer to wastes that are toxic, flammable, corrosive, reactive, and (or) infectious, and pose serious hazards to ecological and human health. With the improvement of people's awareness of environmental protection, hazardous waste toxicity testing is becoming a concern, and therefore the analysis of toxic substances in waste is of particular importance.

Soil Nutrient Analysis

Lifeasible uses a variety of technical means to provide leaching toxicity (inorganic elements and compounds, organic pesticides, non-volatile organic compounds, volatile organic compounds), acute toxicity (oral toxicity, skin contact toxicity, inhalation toxicity), and toxic substance content (highly toxic substances, toxic substances, carcinogenic substances, mutagenic substances, reproductive toxic substances, persistent organic pollutants) testing services. The migration characteristics of semi-volatile and volatile organic and inorganic components in waste (solid and multi-phase) can be determined for waste toxicity testing.

Sample pre-treatment methods

Due to the complexity of the nature and composition of the waste, sample pre-treatment requires maximum extraction of toxic substances while considering the interference of complex matrices with the target toxic substances. Lifeasible uses sample pre-treatment techniques such as microwave-assisted acid digestion, alkali digestion, liquid-liquid extraction with a partition funnel, Soxhlet extraction, and Florisil (magnesium silicate carrier) column cleanup to ensure the accuracy of subsequent analysis and detection of the target toxic substances.
