Organic mercury fungicides were applied to apple trees for many years for controlling fungus-borne diseases of the fruit such as scab. It was of interest to study the magnitude of residues of mercury remaining in such orchard soils long after fungici

Lead arsenate was used for insect control in apple and other fruit orchards for many years. To determine the magnitude and migration of remaining soil residues of arsenic and lead, samples of a clay and a sandy soil were taken at increasing depths at

Heavy metals such as cadmium and lead are typically found at high levels in fly ash from refuse incinerators. In two earlier studies it was found that such heavy metals on grass or tree foliage in the vicinity of old refuse incinerators with relative

There is currently much public opposition to the construction of municipal refuse incinerators in the United States owing to health concerns about emitted toxicants. In this study, 19 elements and polychlorinated biphenyls (PCBs) were determined in g

Santoflex 13, (N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine), is an antiozonant used in the formulation of rubber products. Its application as a dust was shown to offer foliar protection against visible ozone injury when apple seedlings, bean

Visible injury to apple foliage from exposure to ozone includes brown stippling on lower leaf surfaces and a light yellow mosaic on upper surfaces. Histologically, chlorophyll is destroyed and palisade and spongy mesophyll cells collapse following di

Six vegetables and millet were grown on the site of an old orchard which had received heavy applications of lead arsenate and organic mercury fungicides for many years. Carrots and millet absorbed about 7 ppm (dry weight) of lead, the other crops con

A water flux model, which assumes that the dynamic functioning of the soil-plant-atmosphere continuum may be described by a series of steady states, was examined as a means for interpreting leaf water potential measurements in ‘Valencia’ orange t
