Приведены новые результаты анализа удельного содержания свинца в пылевых выбросах в Европе и его связи с загрязнением атмосферного воздуха свинцом для объяснения наблюдаемых различий в трендах выбросов свинца и его содержания в атмосферном воздухе. Приведены новые результаты анализа удельного содержания свинца в пылевых выбросах в Европе и его связи с загрязнением атмосферного воздуха свинцом для объяснения наблюдаемых различий в трендах выбросов свинца и его содержания в атмосферном воздухе. Выявлена тесная связь тренда содержания свинца в атмосферном воздухе с трендом удельного содержания свинца в пылевых выбросах. Предложен показатель удельного содержания свинца в пылевых выбросах (удельный выброс свинца) в качестве индикатора воздействия различных производственных секторов на воздушную среду. Рассчитанное отношение выбросов свинца к валовым выбросам пыли (удельное содержание свинца в пыли) в странах ЕС-28 сократилось с 3014,2 мг/кг в 1990 г. до 1096,5 мг/кг в 2000 г. и 530,5 мг/кг в 2015 г. Показано, что сокращение загрязнения атмосферного воздуха свинцом происходит в основном за счет сокращения загрязнения аэрозолей свинцом. Проанализирован возможный вклад недостаточно полно учитываемых источников в загрязнение атмосферного воздуха свинцом. Показано, что наиболее вероятным среди предполагаемых недостаточно учтенных источников выбросов свинца является истирание тормозов моторных транспортных средств.

New results of the analysis of the specific content of lead in dust emissions in Europe and its connection with air pollution by lead are given to explain the odserved differences in trends of lead emission and its content in ambient air. A close correlation has been revealed between trend in lead content in atmospheric air and trend of the specific content of lead in dust emissions. The relative content of lead in dust emissions (specific lead emission) is proposed as an indicator of the impact of various industrial sectors on the air. The calculated ratio of lead emissions to total dust emissions (specific lead content content in dust) in the EU-28 decreased from 3014.2 mg/kg in 1990 to 1096.5 mg/kg in 2000 and 530.5 mg/kg in 2015. It is concluded that lead pollution in the atmosphere decreased mainly due to the reduction in lead content in aerosols. The possible contribution of insufficiently accounted sources to ambient air pollution by lead has been analyzed. It is shown that the most likely among the expected insufficiently accounted sources of lead emissions is the wear of the brakes of motor vehicles.
