Arsenic and Lead Uptake by Vegetable Crops Grown on an Old Orchard Site Amended with Compost.
The potential for lead (Pb) and arsenic (As) transfer into vegetables was studied on old orchard land contaminated by lead arsenate pesticides. Root (carrot), leafy (lettuce), and vegetable fruits (green bean, tomato) were grown on seven "miniplots" with soil concentrations ranging from near background to ≈ 800 and ≈ 200 mg kg-1 of total Pb and As, respectively. Each miniplot was divided into s...
متن کاملAccumulation of Lead and Arsenic by Lettuce Grown on Lead-arsenate Contaminated Orchard Soils
s: Lead-arsenate was used to control codling moth (Cydia pomonella) in apple (Malus sylvestris Mill) orchards from the 1900’s to the1960’s. Lead and arsenic are generally immobile and remain in the surface soil. Some orchard lands are being used for vegetable crop production. There are concerns of lead and arsenic accumulation in vegetables crops grown in these soils. Objectives were to 1) dete...
متن کاملSpatial and temporal variability of arsenic solid-state speciation in historically lead arsenate contaminated soils.
The arsenic (As) solid-state speciation (i.e., oxidation state, precipitates, and adsorption complexes) is one of the most important factors controlling dissolved As concentrations at As contaminated sites. In this case study, two representative subsurface samples (i.e., oxidized and semi-reduced sites) from former lead arsenate contaminated soils in the northeastern United States were chosen t...
متن کاملPhytoremediation of arsenic contaminated paddy soils with Pteris vittata markedly reduces arsenic uptake by rice.
Arsenic (As) accumulation in food crops such as rice is of major concern. To investigate whether phytoremediation can reduce As uptake by rice, the As hyperaccumulator Pteris vittata was grown in five contaminated paddy soils in a pot experiment. Over a 9-month period P. vittata removed 3.5-11.4% of the total soil As, and decreased phosphate-extractable As and soil pore water As by 11-38% and 1...
متن کاملArsenic Accumulation and Translocation in Mangrove (Aegiceras corniculatum L.) Grown in Arsenic Contaminated Soils
Mangrove wetlands serve as both a sink and source for arsenic (As), as mangrove plants are able to uptake and accumulate As. The present study used pot experiments to evaluate As accumulation and translocation in mangrove (Aegiceras corniculatum L.) seedlings grown in As contaminated soils. Results indicated that A. corniculatum seedlings grew normally under As stress with minute growth inhibit...
