Hourly elemental composition of fine and coarse fraction measured during summer. Improved source apportionment by PMF compared to previous work in London. Sources included marine, soil, traffic, secondary inorganic, construction, Zn-Pb. Regional sources were major contributors to the coarse fraction at both sites. Shipping and industrial emissions have significant impact upon secondary aerosol.
