Perchlorate and chlorate contamination associated with fireworks in Kerala, India
Abstract Firework displays are an integral part of festivals. Kerala is a host of innumerable firework displays. Perchlorate is used as an oxidizer in fireworks. Water samples and soil samples collected after firework display in selected sites of Kerala were analyzed using liquid chromatography–mass spectrometry (LC–MS). Both soil and water samples after the firework display were found to be contaminated with perchlorate. Average perchlorate in soil ranges from below detectable limits to 20451.14 ppb and in water from below detectable limits to 7.23 ppb. Perchlorate in soil was found to be maximum on the third day after the fireworks display. The present study gives an awareness of the perchlorate contamination resulting from the fireworks display in Kerala.
期刊介绍：
Environmental Forensics provides a forum for scientific investigations that address environment contamination, its sources, and the historical reconstruction of its release into the environment. The context for investigations that form the published papers in the journal are often subjects to regulatory or legal proceedings, public scrutiny, and debate. In all contexts, rigorous scientific underpinnings guide the subject investigations.
Specifically, the journal is an international, quarterly, peer-reviewed publication offering scientific studies that explore or are relevant to the source, age, fate, transport, as well as human health and ecological effects of environmental contamination. Journal subject matter encompasses all aspects of contamination mentioned above within the environmental media of air, water, soil, sediments and biota. Data evaluation and analysis approaches are highlighted as well including multivariate statistical methods. Journal focus is on scientific and technical information, data, and critical analysis in the following areas:
-Contaminant Fingerprinting for source identification and/or age-dating, including (but not limited to) chemical, isotopic, chiral, mineralogical/microscopy techniques, DNA and tree-ring fingerprinting
-Specific Evaluative Techniques for source identification and/or age-dating including (but not limited to) historical document and aerial photography review, signature chemicals, atmospheric tracers and markets forensics, background concentration evaluations.
-Statistical Evaluation, Contaminant Modeling and Data Visualization
-Vapor Intrusion including delineating the source and background values of indoor air contamination
-Integrated Case Studies, employing environmental fate techniques
-Legal Considerations, including strategic considerations for environmental fate in litigation and arbitration, and regulatory statutes and actions
