Climate change projections for increases in the frequency and intensity of extreme weather events could have a marked impact on runoff water quality. The objective of this research program is to define the effects of storms and droughts on runoff patterns and chemistry at headwater, forested streams in the acid-sensitive Precambrian Shield region of Ontario.The instrument requested in this grant application will allow the analysis of chemical concentrations in runoff water, including total phosphorus, total nitrogen, nitrate and sulphate.

气候变化对极端天气事件频率和强度增加的预测可能对径流水质产生显著影响。本研究计划的目的是确定暴雨和干旱对径流模式和化学的影响，在源头，森林溪流在酸敏感的前寒武纪盾地区的安大略。在此拨款申请中要求的仪器将允许分析径流水中的化学浓度，包括总磷，总氮，硝酸盐和硫酸盐。
