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...

15 صفحه اولAssessment of uncertainty and risk in modeling regional heavy-metal accumulation in agricultural soils.
Present agricultural land use and atmospheric deposition may lead to heavy-metal accumulation rates in soils that may violate soil quality standards in the future. To undertake suitable preventive measures against heavy-metal enrichment, flux balances in agroecosystems and their uncertainties have to be assessed. For this reason we developed an empirical stochastic model, PROTERRA-S, that consi...
