Dear Sir,Eye drops(single use)commonly used in clinics do have varying pH values.The use of such drops in the initial management of chemical eye injury may influence the accuracy of pH measurement of the eye,and subsequently influence its management.Chemical eye injury is an ophthalmic emergency,which may be caused by exposure to an acidic(pH【4)or an alkali(pH】10)solution to the eye.Rinsing the eye decreases the concentration of these solutions on ocular surface.The initial management would be copious irrigation with clean or sterile water or Ringer’s solution(pH 7.3-7.4)or its equivalent,of a 展开更多

The development of Persistent Organic Pollutants(POPs) control policy in China in the context of international concerns on POPs was reviewed. The aspects of the Chinese POPs control strategies were analyzed, and compared with those of developed counterparts (e.g. US, EU, Japan). Currently, while the legal framework on POPs management, which complies with international guidelines has been established, it should be improved in the areas of special POPs management, risk assessment, the precautionary principle, life-cycle management and technical support capacity. The analysis of Chinese POPs policy and suggestions for strengthening the science-based decision making capacity are not only useful for Chinese decision-makers, but also a case study for developing world and make a great contribution for the global elimination of POPs to make a toxic-free future. 展开更多

Responding to concerns raised by the Bhopal accident, more and more attention has been paid to local emergency, especially chemical emergency, prevention and planning worldwide, and many chemical emergency response systems for public response personnel have been built. With the successful application of geographical information system (GIS) technology in many fields, GIS can be an efficient tool for effective response to chemical emergencies. The purpose of this paper is to introduce the application of GIS technology in emergency response. Typical GIS technology is simply introduced and some of its existing applications to emergency, mainly natural disaster, response are summarized. Spatial data and spatial analysis requirements for chemical monitoring and emergency response are also discussed in detail. Finally a chemical monitoring and emergency response system under development by combining GIS and expert system for both chemical distribution centers and public response personnel is presented. 展开更多

The combustion of vinyl chloride(VC)after the train derailment accident in Ohio,USA in February,2023 has caused widespread concern around the world.This paper tried to analyze several issues concerning the accident,including the appropriateness of the VC combustion in the emergency response in this accident,the meanings of so-called“controlled combustion”,the potential environmental risks caused by VC and combustion by-products,and follow-up work.In our view,this accident had surely caused environmental and health risks to some extent.Hence,a comprehensive environmental risk assessment is necessary,and then the site with risk should be comprehensively remediated,hazardous waste should be harmlessly treated as soon as possible.Finally,this accident suggests that further efforts should be taken to bridge the gap between chemical safety management and their environmental risk management. 展开更多
