Insight into the forms of nutrients that are most readily assimilated by Microcystis and Anabaena species prevalent in Lake Burragorang and other Sydney water supply reservoirs will assist in determining the key drivers to occurrence of blooms of these organisms, particularly when combined with an understanding of the spatial and temporal distribution of the forms of nutrients, the dynamics of transformation between these various forms and the key parameters of light and temperature. In addition, the particular forms in which nutrients are acquired may influence the extent of toxin production. Thus, the findings of the project will also assist in elucidating the conditions under which toxin generation is expected.

深入了解在Burragorang湖和其他悉尼供水水库中普遍存在的微囊藻和水藻物种最容易吸收的营养物质形式，将有助于确定这些生物大量繁殖的关键驱动因素，特别是当结合对营养物质形式的时空分布、这些不同形式之间转化的动态以及光和温度的关键参数的理解时。此外，获取营养物质的特殊形式可能影响毒素产生的程度。因此，该项目的调查结果也将有助于阐明预期产生毒素的条件。
