Phytoplankton Analysis: What is it? What does it take?

The market in environmental analysis is huge, and set to get bigger, with our water resources needing increasing management to support future sustainability. 

When you hear the term environmental analysis, it probably conjures up images of white-coated scientists, sitting at scientific instruments, streaking various growth media, or swirling beakers.

It’s not a very long drive from the Overlander roadhouse to the old telegraph station of Hamelin Pool, but the dry shrub-like vegetation makes it a rather monotonous one. 412 kata lagi


Risk Assessment and Risk Management of Cyanotoxins

Ibelings BW, Backer LC, Kardinaal WE, Chorus I. Current approaches to cyanotoxin risk assessment and risk management around the globe. Harmful Algae. 2015 Dec;49:63-74.

Toxic cyanobacteria became more widely recognized as a potential health hazard in the 1990s, and in 1998 the World Health Organization (WHO) first published a provisional Guideline Value of 1 μg L-1 for microcystin-LR in drinking-water. 388 kata lagi

Irreversible adaptation of ocean bacteria to climate change

Trichodesmium is a photosynthetic, colony-forming, ocean cyanobacteria that thrives in nutrient-poor parts of the ocean and plays a crucial role in the ocean’s nitrogen cycle. It does so by converting the atmospheric nitrogen into ammonium, which is then easily used up by other organisms in the ocean- from plankton to whales. 472 kata lagi
