Аннотация: Lake Baikal is the biggest reservoir of fresh water with unique flora and fauna; presentlyit is negatively affected by climate change, water warming, industrial emissions, shipping,touristic activities, and Siberian forest fires. The assessment of air pollution - related Baikal’secosystem damage is an unsolved problem. Ship, based expedition exploring the Baikal atmosphericaerosol loading, was performed over the lake area in July 2018. We combine theaerosol near - water and vertical distributions over the Lake Baikal basin with meteorolog-ical observations and air mass transportation simulations. Lidar sounding of aerosol fieldsin the troposphere assesses the atmospheric background in the pristine areas and the pollutionduring fire-affected periods. Aerosol optical properties (scattering and spectral ab-sorption) converted to the particle number size, black carbon (BC) mass, and AbsorptionAngstrom Exponent (AAE) provide the inside into aerosol characterization. Transport of industrialemissions from Krasnoyarsk and Irkutsk regions, and wildfire plumes from Repub-lic of Yakutia relates the pollution sources to the increased concentrations of fine particlenumbers, PM 10 and BC mass over Southern and Northern/Central Baikal, respectively. Thehighest PM 10 and BC are associated to the harbor and touristic areas of intensive shippingand residential biomass burning. Deposition estimates applied to aerosol data exhibit thepollution fluxes to water surface over the whole Baikal area. AAE marks the impact of coalcombustion, residential biomass burning, and wildfires indicating the high pollution levelof the Lake Baikal ecological system .
