Landslides are among hazards which undermine the social, economic and environmental wellbeing of the vulnerable community. Assessment of landslides vulnerability reveals the damages that could be recorded, the severity of the impact and increases the preparedness, response, recovery and mitigation as well. This study aims to estimate landslides vulnerability for the western province of Rwanda. Field survey and secondary data sources identified 96 landslides used to prepare landslides inventory map. Ten factors: altitude, slope angles, normalized difference vegetation Index, land use, distance to roads, soil texture, rainfall, lithology, population density and possession rate of communication tools were analyzed...

Environmental information is acquired and assessed during the environmental impact assessment process for surface-strip coal mine approval. However, integrating these data and quantifying rehabilitation risk using a holistic multi-disciplinary approach is seldom undertaken. We present a rehabilitation risk assessment integrated network (R2 AIN™) framework, that can be applied using Bayesian networks (BNs), to integrate and quantify such rehabilitation risks. Our framework has seven steps, including key integration of rehabilitation risk sources and the quantification of undesired rehabilitation risk events to the final application of mitigation...

Solid-state drives (SSDs) are used as data storage systems in various electronic devices in place of hard-disk drives (HDDs) due to higher speed and durability and lower noise and power consumption. Although SSDs have these advantages, the environmental consequences of the technology transformation from HDD to SSD need to be examined from resource depletion and toxicity management perspectives because most electronic components and devices contain rare, precious, and toxic metals. Thus, the objective of this study was to assess and compare resource depletion and toxicity potentials from metals in an HDD and an SSD on a same capacity basis...

The Bureau of Ocean Energy Management (BOEM) has sponsored 4 maieam monitoring projects in the Oil and Gas Development Area of the Alaskan Beaufort Sea since the 1980 s, the last being the Arctic Nearshore Impact Monitoring in the Development Area III (ANIMIDA III) Project (2014-2017). These studies were conducted to better understand the physical, chemical, and biological environments and how oil and gas activities may impact them. This paper focuses on monitoring sediment hydrocarbon chemistry. The projects included measuring polycyclic aromatic hydrocarbons (PAHs), n-alkanes and isoprenoids (SHCs), and sterane/triterpene (S/T) geochemical biomarkers and determining their distribution, possible sources, and environmental significance in the sediments of the Beaufort Sea and rivers emptying into it...

Contaminant remediation decisions often focus on sediment-organism relationships, omitting the partitioning between sediment and water that exists across a given site. The present study highlights the importance of incorporating non-sedimentary routes of exposure into a non-equilibrium, steady-state food web bioaccumulation model for predicting polychlorinated biphenyl (PCB) concentrations in benthic invertebrates. Specifically, we examined the proportion of overlying water relative to the sediment porewater respired by benthic invertebrates, which has been used in previous studies to examine contaminant bioaccumulation...

The persistence assessment under REACH relies on compartment-specific degradation half-lives derived from laboratory simulation studies with surface water, aquatic sediment or soil. Although these data are given priority, they are not available for most of the compounds. Therefore, according to the Integrated Assessment and Testing Strategy (ITS) for persistence assessment, results from ready biodegradability tests (RBTs) are used within a persistence screening to decide whether a substance is considered as "not persistent" or "potentially persistent"...

Toxicity data for tropical species are often lacking for deriving water quality guidelines (WQGs) and for conducting ecological risk assessment (ERA). To protect and safeguard valuable natural resources and important biodiversity in tropical freshwater ecosystems, a sound framework should be established to assess and manage the ecological risk of an ever-increasing number of chemicals that occur in the tropics. The present study aims to provide a more up-to-date comparison of the species sensitivity distributions (SSDs) between temperate and tropical freshwater species, by incorporating more acute toxicity data which have been documented...

In the United States, there is an absence of federal guidance related to deriving and applying background concentrations at contaminated sediment sites. This has resulted in significant variability, uncertainty, and disagreement regarding how representative background concentrations of chemicals of concern should be derived for these sites. This article discusses important considerations in the derivation of representative background concentrations to be used in the evaluation of contaminated sediment sites...

Toxicity studies on chemicals registered under REACH are provided as summaries instead of submitting a full study report. Since the registration data are used by regulatory agencies to identify chemicals of concern, the study summaries must accurately reflect the information in studies. A "study summary" should include sufficient information on the objectives, methods, results and conclusions in the full study report to determine the relevance of the study. Sometimes a "robust study summary" is required, which should contain more detailed information to enable an independent assessment of the study...

Since the mid-1970 s, thousands of studies have evaluated the toxicity of various chemicals to aquatic organisms. Results from many of these studies have been used to develop species sensitivity distributions (SSDs) or genus sensitivity distributions (GSDs) for deriving water quality guidelines. Recently, there has been more emphasis on evaluating the toxicity of chemicals to sensitive organisms rather than the entire range of sensitivities. The SSD approach is intended to inform the derivation of guidelines for the protection of all species, not just those that were included in the SSD...

High profile reports of detrimental scientific practices leading to retractions in the scientific literature contribute to lack of trust in scientific experts. While the bulk of these have been in the literature of other disciplines, environmental toxicology and chemistry are not free from problems. While we believe that egregious misconduct such as fraud, fabrication of data, or plagiarism is rare, scientific integrity is much broader than the absence of misconduct. We are more concerned with more commonly encountered and nuanced issues such as poor reliability and bias...

Historic, current, and future oil and natural gas development can affect water quality in streams flowing through developed areas. We compared small stream drainages in a semi-arid landscape with varying amounts of disturbance from oil and natural gas development to examine potential effects of this development on surface water quality. We used physical, chemical, and biological approaches to assess water quality and found several potential avenues of degradation. Surface disturbance likely contributed to elevated suspended sediment concentrations and spill history likely led to elevated stream polycyclic aromatic hydrocarbon concentrations...

A comprehensive critical review was undertaken aiming to compare the intrinsic sensitivity of terrestrial plant species (crop species and non-crop wild species) using published literature and unpublished proprietary data generated for the registration of plant protection products (PPPs), and a database was compiled. Data were assessed in order to answer the question whether crops differ from non-crop plants in their intrinsic sensitivity to PPPs. Endpoints were assessed considering further potentially relevant parameters by means of different methods, including a quotient approach, where overall crop-endpoints were divided by matching wild species endpoints...

The European Commission intends to protect vertebrate wildlife populations by regulating Plant Protection Product (PPP) active substances that have endocrine disrupting properties with a hazard-based approach. In this paper we consider how the Commission's hazard-based Regulation and accompanying Guidance can be operationalised to ensure that a technically robust process is used to distinguish between substances with adverse population level effects and those for which it can be demonstrated that adverse effects observed (typically in the laboratory) do not translate into adverse effects at the population level...

Identifying focal bird species appropriate to the situation in which a plant protection product is used is important for refined risk assessment (EFSA, 2009). We analysed the results of extensive field observations of newly-drilled cereal fields in France in autumn over two seasons to determine real bird focal species. In 2011, birds were observed, before and after drilling, on wheat and barley fields drilled with imidacloprid treated seeds (i.e. 'treatment' fields) or seeds treated with other compounds than imidacloprid (i...
