Selenium-dependent glutathione peroxidase-4 (GPx4) catalyzes the reduction of phospholipid hydroperoxides. Because a full gpx4 knockout is embryonic lethal, we examined the effect of deletion of one copy of gpx4 on the activities of three selenoperox

Metalaxyl is a fungicide used for control of Pythium spp. diseases in turfgrass. The downward migration of metalaxyl was studied in irrigated lysimeters containing a fine sandy loam soil alone or sand amended with composted brewery waste, composted s

Downward migration of the fungicide, metalaxyl (N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-alanine methyl ester) in irrigated creeping bentgrass (Agrostic palustris Huds) sand lysimeters was studied as a function of two factors: (1) amending sand with

An analytical survey of elements in ashes sampled nationwide from veterinary college incinerators was reported earlier (Thompson et al. 1995). It was of interest to observe the variation in the elemental composition of ashes sampled repeatedly with t

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 pest control in fruit orchards for many years in the United States, and its residues remain in most of these soils. Since arsenic and lead are toxic and only slightly mobile in soils, an analytical survey was conducted in 1

In 1993 municipal sludges from 16 wastewater treatment plants in large American cities were analyzed for asbestos using polarized light microscopy and dispersion staining. Of the 16 sludge samples analyzed, asbestos was found in 13 (81.3%). Sources o

An earlier study showed that fall application of the fungicide, triadimefon to sandy turfgrass lysimeter plots resulted in rapid appearance of the metabolite, triadimenol in collected leachates but only occasional presence of the parent fungicide. In

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

Wastes generated during leather tanning are commonly added to some commercially available organic fertilizers. Since such tannery wastes are typically high in chromium, the possibility of absorption of the metal by crops was of interest. Swiss chard
