Full textThe different compartments of the hydrosphere are major sinks or sources of CO2 and the role of freshwaters in the global carbon cycle has been recently reevaluated as substantial. Freshwaters show variations of the carbonate system variables at hourly time scales and in a large range. A key limitation for the carbonate system studies is the necessity of accurate, in-situ and high frequency measurements that would provide data with suitable spatial and temporal resolutions to enlighten the processes affecting the carbonate system. With the aim of in-situ and high frequency sensor development to assess the freshwaters whole carbonate system with the simultaneous measurement of the pH-Alkalinity couple, spectrophotometric measurement of these parameters is developped. This work focuses mainly on the spectrophotometric alkalinity (Alk) measurement, which is an original contribution. This new method, consists to neutralize all the basic species taken into account in the Alk by a weak acid (formic acid, HFo) mixed with a pH sensitive dye (bromophenol blue, BPB) to measure accurately the pH end point value and thus deduce the Alk of the sample. After a step of laboratory adjustement, the performance of the spectrophotometric methods is assessed in low pH buffer solutions for pH, commercial mineral and spring waters for Alk and natural freshwaters for both, by a comparison to conventional potentiometric measurements and theoretical calculations. PH measurements show a precision of ±0. 005; Alk measurements show a precision of ±7μM. For Alk measurement, the best accuracy is obtained by downplaying the excess acid term and thus its associed uncertainty. Additionnaly, for both pH and Alk, accuracy relies upon the performance of the spectrophotometer, carefully prepared and defined indicator solution and all very controlled and reliable thermodynamic constants with their temperature and ionic strength dependence. After this step that provide strong theoretical basis which precision and accuracy meet the requirements of scientist working on freshwaters systems, the spectrophotometric pH-Alk method was integrated as an in-situ and high frequency sensor. The integration started by a functioning assessment that leads to some modifications on the prototype. Additionnaly, the integration bring to light others optical, mechanical and chemical troubles that were solved before the method validation where previous performances were increased: pH measurements show a precision of ±0. 002 and Alk measurements show a precision of ±3μM. Finally, the prototype sensor was successfully tested on natural freshwaters (a carbonated french lake and the Seine river). These deployment shows the sensor sturdiness but reveal the difficulty of Alk measurement in waters with high turbidity, that necessitate a filtration step before spectrophotometric measurements

Full textThe purification of mediums containing nitrates and heavy metals (Cd, Cu and Mn) has been realised with three freshwater species : two microalgae (Chlorella vulgaris and Selenastrum capricornutum) and a duckweed Spirodela polyrhiza. The optimal growth conditions for all species are obtained with 150 mg/l of N03- for the microalgae and 200 mg/l for the duckweed. The nitrate toxicity threshold is over 800 mg/I for the three studied species. With low nitrate concentration (21 mg/l), the metals toxicity is very important. For high nitrate concentration, the metals toxicity decreases with time and initial NO3- level. These three metals alter nitrates metabolism by decreasing their absorption and their reduction to nitrites. Cd and Cu clearly inhibit nitrate reductase activity. The IC50 of these two metals, evalued by enzymatic inhibition assay, are very closed with those observed by algal assays. L'he nitrates fixation abilities (F. C. ) fluctuate with time and initial N03- medium. They can reach about 3000 mg N03-/algae gramms after 7 days treatment. The efficiency coefficients (EC) also fluctuate with time, nitrates concentration and especially with nutritif compounds concentration. Chlorella vulgaris and Selenastrum capricornutum comportments are very similar and they show a réal capacity to purifying waters with high nitrates concentrations. Spirodela polyrhiza tolerate higher metals concentrations than the two microalgae and shows a better middle and long term purification
