摘要: The Lake Tahoe Atmospheric Deposition Study (LTADS) was conducted by the California Air Resources Board (CARB) primarily to generate refined estimates of atmospheric deposition nitrogen (N), phosphorous (P), and particulate matter (PM) directly Tahoe, which straddles boundary between states Nevada in United States America. LTADS estimated that approximately 185, 3, 755 metric tons respectively N, P, PM being deposited lake from atmosphere. Various measurements emissions, meteorology, air quality were made within west (typically upwind) Basin better understand pollutant sources contributing deposition. data indicate ammonia (NH3) contributes bulk N loading. Aerosols with diameters greater than 2.5 mm contribute P mass loadings. emission appear be local associated motor vehicles. However, construction, fires, natural also part a much larger research program guide efforts restore remarkable water clarity Tahoe.
