We are requesting a Lachat nutrient analyzer to measure various nitrogen (N) species (NO3-, NH4+, total dissolved nitrogen or total nitrogen) with a high level of precision in both surface and ground waters. Measuring N in freshwaters is of critical importance, since excess N loading to surface and ground waters around the world results in the alteration of the base of the food chain promoting eutrophication as well as the proliferation of toxic species and increases contaminant availability threatening ecosystem and human health. Projects that will be supported through the acquisition of this instrument will consider 1) the ecosystem service trade offs at the food-water nexus; 2) the influence of N pollution on the proliferation of toxic algal and cyanobacterial blooms; 3) the impact of nutrients on transfer of contaminants in the food chain affecting human health; 4) the role of nutrients and N species in altering the biogeochemical cycling of C in the St. Lawrence basin. This request replaces an essential instrument for the success and operations of the Université de Montréal’s Groupe de Recherche en Limnologie et environnement aquatique (GRIL-UdeM) aquatic lab facility. Currently there is no adequate alternative capacity for these measurements for members of this team. The HPQ trained using this instrumentation will be involved in cutting edge, world-class research. Furthermore services provided by our facility will be available to the broader community. Linking the complexities of N cycling to other biogeochemical cycles and ecological processes in freshwaters is a frontier in aquatic science, and this instrument will be essential to develop individual and broader programs in this creative perspective.

我们需要一台Lachat营养物分析仪，以高精度测量地表和地下沃茨中的各种氮（N）物质（NO3-、NH 4+、总溶解氮或总氮）。测量淡水沃茨中的氮是至关重要的，因为世界各地的地表和地下沃茨中过量的氮会导致食物链基础的改变，促进富营养化以及有毒物种的增殖，并增加污染物的可用性，威胁生态系统和人类健康。将通过购买该工具得到支持的项目将考虑：1）食物-水关系中的生态系统服务权衡; 2）氮污染对有毒藻类和蓝藻水华扩散的影响; 3）营养物质对影响人类健康的食物链中污染物转移的影响;（4）营养盐和氮在改变圣劳伦斯盆地碳的地球化学循环中的作用。这一请求取代了蒙特利尔大学湖沼学和水生生物研究小组（GRIL-UdeM）水生实验室设施成功运作的一个重要仪器。目前，该团队成员没有足够的替代能力来进行这些测量。使用这种仪器培训的HPQ将参与尖端的世界级研究。此外，我们的设施提供的服务将提供给更广泛的社区。将N循环的复杂性与淡水中的其他生物地球化学循环和生态过程联系起来是水产科学的前沿，这种仪器对于在这种创造性的视角下开发个人和更广泛的方案至关重要。
