摘要：

Two programs of work are described involving the measurement of environmental pollution over periods from 2 h to many years. The long period measurements are deduced from neutron activation analysis of whole wood samples taken from individual tree rings for trees grown in various locations, and some results for Cd, Sb and Ge levels are reported. In a 2nd series of experiments the concentration of airborne particulate matter is measured using a moving filter (streak sampler) technique to give a continuous record with 2 h resolution. The filter samples are analyzed by proton induced X-ray emission and preliminary data is presented.
