The new method includes both acute and chronic toxicity tests. The test water sample can be either a single substance solution or an actual disinfection water sample. The brine shrimp has high sensitivity and is convenient to hatch and culture. The raw materials are inexpensive and easily available. The requirements for the culture environment are not high, and the toxicity end-point is clear. The new method is simple, sensitive and economical, and therefore, a popularization is feasible in sewage and reuse water plants."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for testing ecotoxicity of disinfection by-products","description":"A method for testing ecotoxicity of disinfection by-products (DBPs) is disclosed, including the following steps: firstly, hatching and culturing a brine shrimp to obtain a second-instar brine shrimp l","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11977068","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
