Nanocolloids (Ncs) are highly dispersed mixtures of nanoscale (1–100 nm) heterogeneous systems, which ubiquitous in aquatic environments. Ncs considered a vital pollutant carrier due to their special surface properties and unique hydrodynamic characteristics. They play an essential role the process promoting migration transformation. In recent years, with increase chemicals environment complexi...

Mogpog River is located in the island of Marinduque, Philippines. It used to be a relatively healthy river where local communities dotting its banks from Barangay Taluntunan down to Barangay Janagdong obtained fishes, crustaceans and other aquatic organisms. Harvesting these resources were either for local consumption or for cash. The river also served as a place for bathing, swimming, washing ...

pesticides are one of the most pollutants in aquatic ecosystems. monitoring of aquatic pollution with these compounds is very important. therefore, health status of aquatic animals can be used as a bio-indicator for pollution monitoring in surface waters. diazinon is an organophosphorous pesticide, which is found in the aquatic environment of iran. the concern has arisen over the ability of thi...

Aquatic organisms have played important roles as early warning and monitoring systems for pollutant burdens in our environment. However, they have significant potential to do even more, just as they have in basic biology where preparations like the squid axon have been essential tools in establishing physiological and biochemical mechanisms. This review provides a brief summary of the history o...

Heavy metals that enter marine environment and remain in the water as well as the sediments are accumulated by aquatic organisms, thus becoming highly good indicators to monitor metal accumulation in the long run. Metals are potentially harmful to humans and most organisms at varied levels of exposure and absorption. Northern East Mediterranean Sea is a crucial region as it is an area, shared b...

A recent commentary speaks to a broad range of potential applications for autonomous chemical sensor networks, including systems that monitor the state of the environment in real time.1 However, the authors of the commentary noted that existing sensor networks are “almost entirely restricted to transducers for detecting physical parameters such as temperature, pressure, light or movement”. They...

A portion of all herbicides applied to forests, croplands, road sides, and gardens are inevitably lost to water bodies either directly through runoff or indirectly by leaching through groundwater into ephemeral streams and lakes. Once in the aquatic environment, herbicides may cause stress within aquatic communities and radically alter community structure. Atrazine is one of the most effective ...

This chapter describes the scientific evidence and regulatory debates concerning one of these oestrogens, ethinyloestradiol (EE2), an active ingredient in the birth control pill. First developed in 1938, it is released to the aquatic environment via wastewater treatment plants. Although it is now clear that wildlife species are exposed to and impacted by a cocktail of endocrine disrupting chemi...

The intensive use of chemical substances such as pesticides, drugs, food additives and industrial chemicals has lead to the subsequent detection of these compounds in many countries. With the improper disposal, they enter the aquatic environment primarily by reaching the wastewater systems. About the residues of pharmaceuticals in the environment, especially in water, is being repeatedly report...
