Achieving sustainable use of the planet will require a new paradigm regarding the relationship between human society and the environment and a concomitant paradigm on the responsibility of those now living to provide a quality life for their descendants for an indefinite period of time. Both industrial ecology and natural capitalism provide useful guidelines and case histories on how these two ...

During the past 50 years, the human population has more than doubled and global agricultural production has similarly risen. However, the productive arable area has increased by just 10%; thus the increased use of pesticides has been a consequence of the demands of human population growth, and its impact has reached global significance. Although we often know a pesticide's mode of action in the...

In view of the extensive use of foraminifers for the pollution monitoring especially their unmatched utility in deciphering the temporal variation in the type and concentration of pollutants at a given location, the literature dealing with the application of foraminifers for pollution studies has been reviewed. The pollution monitoring through foraminifers started with attribution of peculiar f...

In the present study, Mercury (Hg) accumulation in different tissues of Yellowfin seabream under different Hg concentrations in the medium were investigated. For this, PurPuse 45 fish specimen of the same size (19.2±1.8cm and 134.0±36.1 g) were caught from Musa Estuary, in northwest of the Persian Gulf and transferred to the laboratory. Fish were divided into five different groups of 9 fish ...

Cholinesterase (ChE) is one of the most employed biomakers in environmental analysis. Among ChEs, potentially the most significant in environmental terms is acetylcholinesterase (AChE), an enzymatic form that terminates the nerve impulse . Because of its physiological role, Ache has long been considered a highly specific biomarker for organisms exposed to anticholinesterasic agents, primarily a...

Bacillus entomopathogens, especially Bacillus thuringiensis, have been used extensively for control of insect pests in crops, forests, and the aquatic environment. Their safety for vertebrates and nontarget invertebrates has been thoroughly documented in a myriad of studies. Their short term effects on nontarget organisms that are unrelated to target insects is negligible. However, the effect o...
