Abstract
Clean water is at the very core of human survival.Aquatic contamination occurs for multiple reasons ranging from taking the water sources for granted, negligence in waste disposal, deliberate contamination, and technological innovations outpacing development of effective guidelines for life-cycle management and regulations to properly recycle/reuse/dispose commercial products, especially prepared using nanoparticles. Elsewhere, we presented potential toxicity of nanosizedparticles of stannum dioxide, cerium dioxide, silver and iron oxide using model of the sea urchin Paracentrotuslividus, Zebra Fish and theiroff springs. Passage through membranous barriers via the digestive tract to the coelomic fluid is the subject of ongoing study using biomarkers, such as coelomic fluid inside coelomocytes (uptake), cholinesterase activity, and using expression of stress-related proteins (HSP70) and Gonads morphological features.A strategic S&T focus of the ICWI is to identify, assess, and recommend revolutionary conceptual Chem.-Bio Defense solutions and provide strategic solution pathways using field-ready technologies. Ongoing research aims to detect, counter, and mitigate potential security threats and is at the core of our current and ongoing investigations. Aquatic (nano)ecotoxicity is arguably the least understood and requires systematic investigation. An outline of dispersion and characterization methodologies of harmful NPs (weaponized NPs)in different aqueous media will be presented along with acute toxicity and risk assessment methodologies. We present our research activities on genotyping and sequencing genetically modified biological systems which are crucial to identify such risks, and trophic transfer and biosecurity implications of NPs and GMOs dispersed intentionally.
