A review of: “METAL IONS IN BIOLOGICAL SYSTEMS, Vol. 20, Concepts on Metal Ion Toxicity. H. Sigel, Ed., Marcel Dekker, New York, 1986, XXIV = 386 pp., $85.00”

Daphniidae (Crustacea, Anomopoda) have often been utilized in toxicological studies and environmental monitoring of aquatic systems for a number of reasons, such as their sensitivity to toxins and their ease of culture, and because they are such important members of the zooplankton in so many lakes. The extensive literature on the use of Daphnia as a bioindicator of environmental pollution with metal ions is critically reviewed. A summary of the data on the toxicity of metal ions in Daphnia is presented. These studies have lead to attempts to standardize the use of the bioindicator, as well as the monitoring of procedures. There have also been efforts to derive a relationship between toxicity data and the actual properties of toxins. Such a relationship would be beneficial for predicting the power of toxicity. To date, however, the efforts to establish this relationship have not been satisfactory. This compilation of metal toxicity data and the presentation of the attempts to establish such relationships was carried out in anticipation that it would be useful in future studies that might lead to a universal theory of the effect of metal ion toxicity on aquatic organisms.Key words: aquatic toxicology, bioindicators, Daphniidae, metal ion toxicity.

Metal Ion Detection

Abstract Metal ions are widely present in biological systems and participate in many critical biochemical processes such as material transportation, energy conversion, information transmission and metabolic regulation, making them indispensable substance in our body. They can cause health problems when deficiency or excess occurs. To understand various metabolic processes and facilitate diseases diagnosis, it is very important to measure the content and monitor the distribution of metal ions in individual cells, tissues and whole organisms. Among the various methods for metal ion detection, fluorescent sensors with organic dyes have attracted tremendous attention due to many advantages such as high fluorescence quantum yield, facile modification approaches and biocompatibility in addition to operation ease, high sensitivity, fast detection speed, and real-time detection. This review summarizes the recent progress on the detection and imaging of the metal ions in biological systems including Na+, K+, Ca2+, Mg2+, Fe2+/Fe3+, Zn2+, and Cu2+ provides an opinion on remaining challenges to be addressed in this field.
