The response of cotton-topped (CT) or white-lipped (WL) marmosets, inoculated with material containing Epstein-Barr virus (EBV), was studied. Twenty-five marmosets inoculated with 10(6)-10(8) cells from human or simian EBV-carrying lymphoblastoid cell cultures developed no detectable clinical disease. Transitory antibody titres to VCA were detected in sera(More)
A high rate of lead fallout around two secondary lead smelters originated mainly from episodal large-particulate emissions from low-level fugitive sources rather than from stack fumes. The lead content of dustfall, and consequently of soil, vegetation, and outdoor dust, decreased exponentially with distance from the two smelters. Between 13 and 30 percent(More)
I The concentrations of 25 elements were determined instrumentally by 'neutron and photon activation analysis in aerosol samples collected at urban and industrial sites in Toronto. Size distributions for most of these elements were obtained with a five-stage, high-volume Andersen sampler. Many elements associated with larger aerosols (Al, Ca, Fe, La, Mg,(More)
