Summer time
The air here in Brazil gets more moist by the day. The main difference between summer and spring is the dryness. during spring there were multiple fires because of draught almost everywhere, now I'm even having trouble lighting the furnace. You cannot escape the moist, as I am writing this my elbows stick to the desk like glue even though I am not sweating at all.
The project seems to go on quite nicely, currently we have managed to determine the pharmaceuticals that we are going to use in the toxicity assessment together with the methods we are going to use. So, the first method is with the bacteria Aliivibrio Fischeri, the concept is that they will glow when they come in contact with toxic material. We can measure the glow amount with a device called MICROTOX and turn that into a statistic analysis. Secondly we are going to use cucumber seeds to measure the toxicity. We will grow them using water mixed with the pharmaceuticals and look at the state there in after a few days. Finally we use Lemna Minor a.k.a duckweed for the same purpose but Raquel, our supervizor, mentioned that there is a high possibility that the duckweed will perish nontheless but we will see about that. The process of the duckweed is basically the same as the seeds, we look at the growth of the plant. Somewere around the 20th of october, the labs will open after another holiday and we will get started on growing some duckweed!
