The aim was to investigate whether nitrates were abundant in effluent discharge from wastewater treatment Riverbanks and water quality in the plants across South-East Queensland, Australia, river Chimehuin • Walter Eduardo Aigo, Patricio and subsequent impacts on Anabaena circinalis Martín Arce & Joaquín Antú Porma growth (species that has toxigenic Harmful Algal blooms). Although nitrate levels exceeded guidelines Riverbank samplings were carried out through for prevention of eutrophication, however, these vegetation transects on five sites of the river levels did not have a significant impact on the Chimehuin from its source to near the mouth. growth of Algae. Re-evaluation of regulated In those places water quality was also analyzed. nitrate levels may thus be needed.
We made Physic-chemical and biological analysis (temperature, pH, oxygen, alkalinity and nitrates) where we used macroinvertebrates as indicators of water quality. In general the river has banks with vegetation along almost its entire course, except for in urban areas where it has been partially modified. In these areas we observed water quality changes. We propose recommendations for restoration and conservation of riverbanks.

Household and biotechnological methods to reduce the pollution of waters by alkyl sulfates • Tatsiana Pasko & Anna Kotikova Domestic waste (for ex. domestic septic tanks) is an important source of alkyl sulfate to the environment. We have developed, tested, and offered a simple way to use soap economically. These methods are easy to use, envi- ronmentally friendly, cost-effective, and take into account savings in both soap and water. Also, we have developed a biotechnological method of microbial purification using our own detected bacteria and developed biological product based on it. Sharing household and biotechnological methods can significantly reduce the environmental pollution by alkyl sulfates of domestic origin.

It is a little lake formed by the confluence of two streams and situated in a very quiet area. We determined the physical and chemical parameters of its water taking monthly measurements for a year; we also identified and catalogued the benthonic organisms, the water-plants, and the vegetation along the banks. The data we collected showed some critical aspects, so we decided to make our results known to the local population and to ask the administrators for some improving actions.
