The aquatic risk of 2-sulfonato fatty acid methyl ester sodium salt (MES) used in household detergents was assessed. The environmental exposure assessment expressed as predicted environmental concentration (PEC) was determined on the basis of monitoring results from the seven sites of four rivers in the urban area in Tokyo and Osaka. The 95 percentile as well as geometric mean of the MES concen...

Monitoring important aquatic processes like harmful algal blooms is of increasing interest to public health, ecosystem sustainability, marine biology, and aquaculture industry. This paper presents a novel approach to spatiotemporal aquatic field reconstruction using inexpensive, low-power, mobile sensing platforms called robotic fish. Robotic fish networks are a typical example of Cyber-Physica...

The need for assessment of aquatic ecosystem contamination and of its impact on water dwelling organisms was developed in response to rising aquatic environmental pollution. In this field study, liver enzymes of phase I and phase II of xenobiotic transformation, namely cytochrome P450, ethoxyresorufin-O-deethylase, glutathione-S-transferase and tripeptide glutathione were used to assess the con...

malathion (s-(1, 2-dicarboethoxyethyl) o, o-dimethyl phosphorodithioate) is one of the organophosphate pesticides comprehensively used in agriculture fields throughout the world. in spite of widely used, little information are available about dna damage in aquatic organisms. therefore, the present study carried out to investigation of dna damage induced by malathion in cyprinus carpio (pisces: ...

mercury is one of the most toxic heavy metals present in aquatic systems, exhibiting a complex behaviour in the environment, where it may persist for decades after the source of pollution is stopped. hence, it is important develop new techniques for its removal from the aquatic systems. in this context, a particularly promising line of research is the use of new materials capable of up taking m...

Atrazine is widely used in the agriculture as an herbicide. Due to its high mobility, Atrazine leaks into the groundwaters, surface waters, and drinking water wells. Many physical and chemical methods have been suggested for removing Atrazine from aquatic environments. However, these methods are very costly, have many performance problems, produce a lot of toxic intermediates which are very har...

The eighth edition of the Guide for the Care and Use of Laboratory Animals recognizes the widespread use of aquatic and semiaquatic research animals by including, among other references, an entire section on aquatic animals in its chapter on environment, housing, and management. Recognizing the large number of aquatic and semiaquatic species used in research and the inherent diversity in anima...
