High resolution mass spectrometry (HRMS) and non-targeted analysis (NTA) are of increasing interest in chemical forensics for the identification of emerging contaminants and chemical signatures of interest. At the US Environmental Protection Agency, our research using HRMS for non-targeted and suspect screening analyses utilizes databases and cheminformatics approaches that are applicable to chemical forensics. The CompTox Chemicals Dashboard is an open chemistry resource and web-based application containing data for ~900,000 substances. Basic functionality for searching through the data is provided through identifier searches, such as systematic name, trade names and CAS Registry Numbers. Advanced Search capabilities supporting mass spectrometry include mass and formula-based searches, combined substructure-mass searches and searching experimental mass spectral data against predicted fragmentation spectra. A specific type of data mapping in the underpinning database, using “MS-Ready” structures, has proven to be a valuable approach for structure identification that links structures that can be identified via HRMS with related substances in the form of salts, and other multi-component mixtures that are available in commerce. These MS-Ready structures have been used as an input set for computational MS-fragmentation to provide a database against which to search experimental data for spectral matching. This presentation will provide an overview of how the CompTox Chemicals Dashboard supports structure identification and non-targeted analysis in chemical forensics.

Non-targeted screening, targeted screening and suspect screening, as well as “Known Unknowns” and “Unknown Unknowns” are now common terms in the field of water analysis. While data processing can be highly automated, the identification of chemicals from extracted masses, formulae or fragmentation utilizes reference spectral libraries or identification and ranking of tentative candidate lists from large structure libraries. The US-EPA CompTox Chemicals Dashboard (https://comptox.epa.gov/dashboard) provides access to data for ~875,000 substances, searchable by mass and formula and then ranked using associated meta-data. Cheminformatics approaches are also utilized to provide mapped relationships between individual substances and their “MS-Ready” (desalted, non-stereospecific) forms. This presentation will review how the freely available Dashboard application can be utilized to support structure identification using mass spectrometry and our efforts to enhance the application using computational spectral fragmentation and access to predicted data such as relative retention time index values and computed collision cross section values to support ion mobility spectrometry.

There is increasing interest in the environmental impact of per- and polyfluoroalkyl substances (PFAS) chemicals and the aggregation of related data provides both agency and public access to support research. The US-EPA’s CompTox Chemicals Dashboard (https://comptox.epa.gov/dashboard) is a publicly accessible website providing access to data for ~875,000 chemical substances, including thousands of PFAS chemicals. The dashboard provides access to a wide array of experimental and predicted physicochemical properties, in vitro bioactivity and in vivo toxicity data, product use information and integrated linkages to a growing list of literature, toxicology, and analytical chemistry websites. The assembly of data has required hundreds of hours of manual curation and data checking to deliver a number of segregated lists of PFAS chemicals. Experimental data extracted from literature articles has allowed the optimization of QSAR models for the prediction of properties such as logP (octanol-water partition) and aqueous solubility. This presentation will provide an overview of the dashboard, the ongoing expansion of the PFAS chemical library, with associated categorization, and new physicochemical property and environmental fate and transport QSAR prediction models being developed for these chemicals. Our progress in the measurement and analysis of bioactivity data for PFAS chemicals will also be reviewed.

Researchers at EPA’s National Center for Computational Toxicology integrate advances in biology, chemistry, and computer science to examine the toxicity of chemicals and help prioritize chemicals for further research based on potential human health risks. The goal of this research program is to quickly evaluate thousands of chemicals, but at a much reduced cost and shorter time frame relative to traditional approaches. The data generated by the Center includes characterization of thousands of chemicals across hundreds of high-throughput screening assays, consumer use and production information, pharmacokinetic properties, literature data, physical-chemical properties as well as the predictive computational modeling of toxicity and exposure. We have developed a number of databases and applications to deliver the data to the public, academic community, industry stakeholders, and regulators. This presentation will provide an overview of our work to develop an architecture that integrates diverse large-scale data from the chemical and biological domains, our approaches to disseminate these data, and the delivery of models supporting predictive computational toxicology. In particular, this presentation will review our new CompTox Chemistry Dashboard and the developing architecture to support real-time property and toxicity endpoint prediction.

Non-targeted analysis (NTA) uses high-resolution mass spectrometry to better understand the identity of a wide variety of chemicals present in environmental samples (and other matrices). However, data processing remains challenging due to the vast number of chemicals detected in samples, software and computational requirements of data processing, and inherent uncertainty in confidently identifying chemicals from candidate lists. Analysis of the resultant mass spectrometry information relies on cheminformatics to identify and rank chemicals and the US EPA has developed functionality within the CompTox Chemicals Dashboard (https://comptox.epa.gov/dashboard) to address challenges related to this analysis. These tools include the generation of “MS-Ready” structures to optimize database searching, retention time prediction for candidate reduction, consensus ranking using chemical metadata, and in silico MS/MS fragmentation prediction for spectral matching. Combining these tools into a comprehensive workflow improves certainty in candidate identification. This presentation will review how the CompTox Chemicals Dashboard via its flexible search capabilities, rich data for ~875,000 chemical substances, and visualization approaches within this open chemistry resource provides a freely available software tool to support structure identification and NTA.

ChemSpider is a free access website for chemists built with the intention of providing a structure centric community for chemists. It was developed to index available sources of chemical structures and their associated data into a single searchable repository and making it available to everybody, at no charge. While there are a large number of databases containing chemical compounds and data available online their inherent quality, accuracy and completeness is severely lacking. ChemSpider has provided a platform so that the chemistry community could contribute to improving the quality of data online and expanding the information to include data such as reaction syntheses, analytical data, experimental properties and linkages to other valuable resources. It has grown into a resource containing over 21 million unique chemical structures from over 200 data sources.
This presentation will provide an overview of ChemSpider and its value to chemists as a search tool, as a public repository of information and how it can become one of the primary foundations of internet-based chemistry. I will also discuss the vision for ChemSpider and some of the lofty goals we are setting for the system moving forward.

ChemSpider is a free access website for chemists built with the vision of providing a structure centric community for chemists. Vision is great…execution is better. ChemSpider is now one of the internet’s primary portals for chemistry offering access to over 23 million unique chemical structures from over 200 data sources and expanding daily. Even though there are tens if not hundreds of chemical structure databases such as literature data, chemical vendor catalogs, molecular properties, environmental data, toxicity data, analytical data etc. there has been no single way to search across them. Despite the fact that there are a large number of databases containing chemical compounds and data available online their inherent quality, accuracy and completeness remains lacking in many regards. With ChemSpider we have provided a platform whereby the chemistry community could contribute to cleaning up the data, improving the quality of data online and expanding the information available to include data such as reaction syntheses, analytical data, experimental properties and linking to other valuable resources.

Scientists commonly find themselves in a state of overwhelm in regards to the availability of information accessible to them. The distribution of resources now includes the entire space of the worldwide web, access to primary databases such as CAS and, commonly, a plethora of internally developed systems. While the web has provided improved access to chemistry-related information there has not been an online central resource allowing integrated chemical structure-searching of chemistry databases, chemistry articles, patents and web pages such as blogs and wikis. ChemSpider has built a structure centric community for chemists by providing free access to an online database and collaboration tool for chemists. The online database offers an environment for curating the data on ChemSpider as well as the deposition of chemical structures, analytical data and associated information and provides a significant knowledge base and resource for chemists working in different domains.

The World Wide Web continues to have an expanding and profound effect on providing access to chemical information. A chemist may wish to know a variety of information about a given chemical compound including physical and chemical properties, molecular structure, spectral data, synthetic methods, known reactions, safety information, and systematic nomenclature and chemical names. In the past, having access to this variety of information required a small library of different reference works, since no one resource contained all this data. This was problematic both in terms of cost and physical space for storage. Now there is a single web site that not only provides all this information for millions of compounds but also is free.

There is an increasing availability of free and open access resources for scientists to use on the internet. Coupled with an increasing number of Open Source software programs we are in the middle of a revolution in data availability and tools to manipulate these data. ChemSpider is a free access website built with the intention of providing a structure centric community for chemists. As an aggregator of chemistry related information from many sources, at present over 21.5 million unique chemical entities from over 190 separate data sources, ChemSpider has taken on the task of both robotically and manually integrating and curating publicly available data sources. ChemSpider has also provided an environment for users to deposit, curate and annotate chemistry-related information. This has allowed the community to enhance ChemSpider by adding analytical data, associating synthetic pathways and publications and connecting to social networking resources. I will discuss how ChemSpider is fast becoming the premier curated platform and centralized hub for resourcing information about chemical entities and how the platform provides the foundation data for services allowing the analysis of analytical data and collaborative science.ChemSpider as a Foundation for Crowdsourcing and Collaborations in Open Chemi...

The internet has provided access to unprecedented quantities of data. In the domain of chemistry specifically over the past decade the web has become populated with tens of millions of chemical structures and related properties of assays together with tens of thousands of spectra and syntheses. The data have, to a large extent, remained disparate and disconnected. In recent years with the wave of Web 2.0 participation any chemist can contribute to both the sharing and validation of chemistry-related data whether it be via Wikipedia, the online encyclopedia, or one of the multiple public compound databases. The presentation will offer a perspective of what is available today, our experiences of building a public compound database to link together the internet and a suggested path forward for enabling even greater integration and connectivity for chemistry data for the masses to both use and participate in developing.

With an intention to provide a free internet resource of chemistry related data for the community, ChemSpider provides an online database of chemical compounds, reaction syntheses and related data. Members of the community can contribute to the database via the deposition of chemical structures, synthesis procedures and analytical data. Data are also aggregated from many other depositors, at present over 400 data sources. The aggregation of data associated with over 25 million chemical compounds does not come without data quality issues. By engaging the community to curate the data the quality continues to improve on a daily basis. The presentation will provide an overview of our ongoing efforts to expand and curate the database. Using a combination of game-based and recognition systems as well as our dependence on societal giveaway by the community ChemSpider continues its path to become a high quality resource and foundation for the semantic web for chemistry.How Community Crowdsourcing and Social Networking is Helping to Build a Quali...

ChemSpider was developed with the intention of aggregating and indexing available sources of chemical structures and their associated information into a single searchable repository and making it available to everybody, at no charge. There are many tens of chemical structure databases such as literature data, chemical vendor catalogs, molecular properties, environmental data, toxicity data, analytical data etc. and no single way to search across them. Despite the diversity of databases available online their inherent quality, accuracy and completeness is lacking in many regards. ChemSpider was established to provide a platform whereby the chemistry community could contribute to cleaning up the data, improving the quality of data online and expanding the information available to include data such as reaction syntheses, analytical data and experimental properties. ChemSpider has now grown into a database of over 20 million chemical substances integrated with over 300 disparate data sources, many of these directly supporting the Life Sciences. This presentation will provide an overview of our efforts to improve the quality of data online, to provide a foundation for the semantic web for chemistry and to provide access to a set online tools and services to support access to these data. I will also discuss how ChemSpider is being used to enhance Semantic Publishing in Chemistry at RSC.
