Evaluation of ballast water risk assessment

Risk Assessment as a Decision Supporting Tool in Ballast Water Management

After almost two decades of intensified research, regulatory and political activities focussed on the prevention of harmful organisms and pathogen transfers around the world, in 2004 the International Convention on the Management of Ships’ Ballast Water and Sediments (BWM Convention) was adopted to provide for a common and globally uniform ballast water management (BWM) approach. Recognising th...

Risk assessment of heterotrophic bacteria from bottled drinking water sold in Indian markets.

One hundred and five samples of bottled drinking water belonging to 30 different brands, collected from six different states of India have been analysed for total heterotrophic bacterial (THB) load and coliforms. Almost all bottlers used multiple treatment procedures such as microfiltration, reverse osmosis and ozonization to treat the water. Around 40% of the samples exceeded the limit of 100 ...

Risk assessment and water management

In order to implement water management in a sustainable way, the related decisionmaking processes have to take the ecological and socio-economic consequences into account. In the Netherlands, policy makers struggle with the question how they can deal with risks associated with flooding.

The Effectiveness of the Ballast Water Exchange Method in Removal of the Heavy Metals in the Ballast Tanks of the Ships, Bushehr Port- Persian Gulf

Ships transport about 80 percent of world trade and transfer approximately three to five billion tons of ballast water internationally every year. Due to the likely presence of pollutants, the ballast water discharged by ships can have negative effects on aquatic ecosystems. This study was conducted on 10 ships that entered the Bushehr port to determine the effectiveness of the ballast water ex...
