You are interested to investigate the availability of dissolved inorganic nitrogen (as ammonia and nitrate) in coastal waters. Your analyses indicate those concentrations are 0.22 mg NH4+ L-1 and 0.34 mg NO3- L-1 respectively. Based on your data, what is the total concentration of dissolved inorganic nitrogen (as NH4+ + NO3-), in units of μM?

    Dissolved ammonia is a common contaminant in drinking water, streams, and rivers. The dissolved form can cause an unpleasant taste in the water and is toxic to many aquatic life forms. Gaseous ammonia (NH3) has an unpleasant odor that has been described as similar to baby diapers or window cleaner. b. Fish are very sensitive to un-ionized ammonia (NH3) and concentrations as low as I .0 mg/L can be toxic. If you took a sample of water downstream of a...

    7. (10) The total CO2 (TCO,) concentration of seawater is roughly 2,300 umoles/L; you will recall that TCO2 includes the sum of carbonate (CO3), bicarbonate (HC03) and carbon dioxide (CO2). At normal ocean pH (roughly pH 8) bicarbonate is the most abundant inorganic carbon species and carbon dioxide (CO2 per se) is present at a concentration of roughly 15 umoles/L Typical deep water nitrate and phosphate concentrations are 40 and 3 umoles/L, respectively. Is dissolved inorganic carbon a limiting resource...

    10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...

    explaim the mechanisms amd toxological effects if type 1 diabetes in this article Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
