I have been studying impacts of air pollution on plants for about 40 years. During my early work in Poland (1972 – 1981), I developed methodologies for evaluation of environmental pollution using chemical analysis of plants. Together with my colleagues of the Warsaw Botanic Garden, Polish Academy of Sciences, I produced maps of sulfur dioxide, fluorides and heavy metals distribution in Poland based on chemical composition of Scots pine (Pinus sylvestris L.) needles. Later (1981 – 1990) at the Statewide Air Pollution Research Center of the University of California in Riverside I was involved in evaluation of air pollution (ozone, sulfur dioxide, nitrogen oxides) effects on growth, injury development, physiology and biochemistry of various agricultural crops in California. At that time I also started my collaboration with Dr. Paul Miller of the USDA FS Fire Laboratory in Riverside and got involved in evaluation of nitrogenous air pollution and atmospheric nitrogen and sulfur dry deposition to California ecosystems. Still working for UCR, I characterized air pollution and atmospheric dry deposition to the chaparral, mixed conifer forest and subalpine ecosystems of the San Gabriel and San Bernardino Mountains in southern California and the Sierra Nevada Mountains.
Since joining the USDA Forest Service (1990), my work mostly focused on refining methods for determining air pollution status and evaluating atmospheric deposition in remote mountain areas. For that purpose I adapted existing passive sampler methodologies for ozone, ammonia, nitrogen oxides, and sulfur dioxide. I also developed a passive sampler for nitric acid vapor, one of the most important nitrogenous pollutants in the wildland-urban interface of the arid regions. Results from passive sampler determinations have been used for development of geostatistical maps of air pollution distribution at scales of landscapes and regions. In my studies I also used portable, battery operated UV absorption instruments for the real-time measurements of ozone concentrations in complex mountain terrain. Such information is needed for understanding toxic effects of ozone on human health and ecosystem sustainability. I have been involved in various air pollution-related projects in western United States and Central Europe. In collaboration with the USDA FS partners I characterized distribution of ambient ozone and nitrogenous pollutants in the San Bernardino Mountains of southern California and the Sierra Nevada Mountains, including Sequoia National Park and the Lake Tahoe Basin. In 1990s I coordinated several research projects in Central Europe aimed at understanding distribution and effects of ambient ozone on local forests. Together with my European and US colleagues I discovered that ozone levels on that part of Europe were elevated and contributed to deterioration of forest condition in the Carpathian Mountain range. Recently I have been involved in research on understanding impacts of wildland fires on air quality from a perspective of human and ecosystem health.
I have been actively involved in activities of the International Union of Forest Research Organizations (IUFRO). Since 2010, I have been serving as a Coordinator of its Research Group 7.01 "Impacts of Air Pollution and Climate Change on Forest Ecosystems", a Deputy Coordinator of IUFRO Division 7 "Forest Health" and a Member of the IUFRO Enlarged Board. I am also a visiting professor at the Department of Environmental Sciences of the University of California in Riverside.
