Addressing Gaps in Environmental Emergency Planning: Hazardous Materials Releases during Earthquakes

Hazardous materials, in many forms, are ubiquitous in modern society. They are integrated into communities in the form of manufacturing and commercial establishments, medical facilities and laboratories-'hazmat' also circulates through communities in the transportation process, by rail, truck and pipeline. In areas vulnerable to earthquakes, hazmat releases constitute a secondary disaster that can be triggered by seismic action. This paper points out that little research and management attention have been given to the issue of earthquake-induced hazardous materials releases. The problem and its potential consequences are defined, and the history of hazmat releases in recent earthquakes is reviewed. Existing studies of earthquakeinduced hazardous materials releases are critiqued to identify gaps in knowledge that should be filled as a preface to meaningful efforts at planning for this hazard. Suggestions are outlined for the types of information needed to establish a database from which threat assessments, mitigation measures and emergency response strategies may be derived.     

Environmental hazards and psychopathology: Linking natural disasters with mental health

For some years, social scientists have been unable to agree on the extent to which experiencing a natural disaster is related to the presence of psychopathological symptoms Indeed, social scientists appear to be well-polarized, some arguing that disasters cause severe negative psychological reactions in victims, with others claiming that any psychological effects, if they exist at all, are minor and transient This paper reviews the controversy and identifies numerous conceptual and methodological difficulties associated with the competing positions. It is argued that the preoccupation of researchers with documenting positive or negative instances of psychological effects has lead them to ignore the issue of identifying processes through which disasters might impinge upon an individual's emotional stability. As a first step toward sketching out these processes, an extensive review of the literature on human response to natural disasters is undertaken. Eleven variables—level of community preparedness, scope of impact, duration of impact, destruction of kin and friendship networks, property damage, pre-impact psychological stability, social support, grief reactions, availability of institutional help, and successful coping skills—are identified as important in determining the psychological impact of disasters. These variables are operationalized and arranged into an interpretative framework that postulates the nature and magnitude of the interrelationships among them based upon the existing research literature     

Plans to distribute the next billion computers by 2015 creates lead pollution risk

Major computer and software companies, along with governments and philanthropic organizations have embarked on ambitious plans to put computers in the hands of more than one billion new computer users over the next five to six years in untapped markets in emerging economies. The most frequently proposed solution to overcome the electricity shortfall in communities where new computer users will be located is to use rechargeable lead-acid batteries to provide primary and back-up power for computers. This paper calculates the lead emissions from battery manufacturing and recycling that will result if independent market projections to greatly expand the number, geographic, and socioeconomic distribution of computer users are realized. By examining several possible scenarios, we estimate that between 1250 and 2300 kt of lead – between four and seven times the weight of the Empire State Building – could be released into the environment in the developing world to provide power to computers sold through 2015. Increased lead exposure has a negative impact on children's neurological development as measured by reduced school performance and on standardized tests. In order to realize the educational achievement and economic development benefits of reducing the “digital divide” proponents will need to encourage improvements in lead battery production and recycling in targeted markets.     

The scope and severity of white-nose syndrome on hibernating bats in North America

Assessing the scope and severity of threats is necessary for evaluating impacts on populations to inform conservation planning. Quantitative threat assessment often requires monitoring programs that provide reliable data over relevant spatial and temporal scales, yet such programs can be difficult to justify until there is an apparent stressor. Leveraging efforts of wildlife management agencies to record winter counts of hibernating bats, we collated data for 5 species from over 200 sites across 27 U.S. states and 2 Canadian provinces from 1995 to 2018 to determine the impact of white-nose syndrome (WNS), a deadly disease of hibernating bats. We estimated declines of winter counts of bat colonies at sites where the invasive fungus that causes WNS (Pseudogymnoascus destructans) had been detected to assess the threat impact of WNS. Three species undergoing species status assessment by the U.S. Fish and Wildlife Service (Myotis septentrionalis, Myotis lucifugus, and Perimyotis subflavus) declined by more than 90%, which warrants classifying the severity of the WNS threat as extreme based on criteria used by NatureServe. The scope of the WNS threat as defined by NatureServe criteria was large (36% of Myotis lucifugus range) to pervasive (79% of Myotis septentrionalis range) for these species. Declines for 2 other species (Myotis sodalis and Eptesicus fuscus) were less severe but still qualified as moderate to serious based on NatureServe criteria. Data-sharing across jurisdictions provided a comprehensive evaluation of scope and severity of the threat of WNS and indicated regional differences that can inform response efforts at international, national, and state or provincial jurisdictions. We assessed the threat impact of an emerging infectious disease by uniting monitoring efforts across jurisdictional boundaries and demonstrated the importance of coordinated monitoring programs, such as the North American Bat Monitoring Program (NABat), for data-driven conservation assessments and planning.
