Rapid detection method of ship ballast water biomass based on spectrophotometry

A Rapid Method Based on Uv Spectrophotometry for Quantitative Determination of Allicin in Aqueous Garlic Extracts

Garlic (Allium sativum) is known for its medicinal and health food use. However, garlic extracts are also used in bio-pesticides. This study reports research on the optimisation of a fast and cheap method for assaying allicin, the active constituent of garlic extract, based on UV spectrophotometry. Garlic cloves were extracted using water. The allicin content of the garlic extracts was analysed...

Review of interdisciplinary devices for detecting the quality of ship ballast water

The results of the ship ballast water treatment systems neutralization need to be verified in a transparent and trustful way before the ship enters a port. Some researches and results, explained in this article, confirm a need for a good verification. If there is no good methodology agreed, then it would not be accepted the solution that the BWMC (Ballast Water Management Convention) 2004 did p...

Novel Electrokinetic Microfluidic Detector for Evaluating Effectiveness of Microalgae Disinfection in Ship Ballast Water

Ship ballast water treatment methods face many technical challenges. The effectiveness of every treatment method usually is evaluated by using large scale equipment and a large volume of samples, which involves time-consuming, laborious, and complex operations. This paper reports the development of a novel, simple and fast platform of methodology in evaluating the efficiency and the best parame...

Temporal modelling of ballast water discharge and ship-mediated invasion risk to Australia

Biological invasions have the potential to cause extensive ecological and economic damage. Maritime trade facilitates biological invasions by transferring species in ballast water, and on ships' hulls. With volumes of maritime trade increasing globally, efforts to prevent these biological invasions are of significant importance. Both the International Maritime Organization and the Australian go...
