Two-dimensional code type chemical toxicity information building and searching method

Abstract

The invention discloses a two-dimensional code type chemical toxicity information building and searching method. Biophysical-chemical information and biological toxicity information of chemicals are collected, information introduction is simplified, the chemicals are divided into four types including severe toxicity, high toxicity, middle toxicity and low toxicity, hazard classes of the toxicity of the chemicals to human bodies are calculated by a comprehensive index method according to chemical toxicity classification grades, a simple chemical toxicity information list not exceeding 140 characters is generated according to the biophysical-chemical information and biological toxicity grade information of the chemicals, the simple chemical toxicity information list is converted into two-dimensional codes with different sizes through a two-dimensional code converter, the two-dimensional codes are laminated and pasted on a chemical outer package, an APP (application) is scanned by the two-dimensional codes on handheld wireless mobile terminals such as a smart phone with a scanning function, chemical users rapidly, simply and conveniently acquire, store and spread the toxicity information of the chemicals at low cost, and toxicity warning and health protection functions are achieved.

Description

technical field [0001] The invention belongs to the field of inquiry methods for environmental chemical toxicity information, and in particular relates to a two-dimensional code type chemical toxicity information construction and inquiry method. Background technique [0002] During the transportation and use of hazardous chemicals, proper packaging is required to avoid safety problems and cause heavy property losses and casualties. Adding easily identifiable warning signs to packaging based on chemical classification is a current research hotspot [Zhao Lei, Hazardous Chemical Packaging Safety Issues and Strategies. Science and Technology Innovation and Application, No. 9, 2014]. The international chemical safety label includes chemical number, chemical name, chemical formula, molecular weight, hazard, exposure type, acute hazard / symptom, prevention, first aid / firefighting, spill disposal, storage, packaging and labeling, important data, physical properties, Data and many ot...

Problems solved by technology

[0008] The technical problem to be solved in the present invention is to use two-dimensional code technology to construct physical information (product instructions) of chemicals for the problems that the instructions of quasi-chemicals are too complicated and inconvenient for non-professionals to read, so that users cannot understand their specific toxicity information. digital manual
