为指导正确评价多环芳烃污染农田土壤生态修复效果及环境风险，根据辽宁省农田土壤多环芳烃污染状况、多环芳烃污染农田土壤生态修复技术特点，参考国内外相关标准，应用生态风险模型，建立辽宁省地方标准（DB 21/T 2274-2014）---多环芳烃污染农田土壤生态修复标准，提出了生态修复完成后农田土壤中总多环芳烃浓度和苯并[a]芘环境当量总浓度限值。主要内容为：生态修复完成后农田土壤中总多环芳烃浓度低于2 mg/kg，生态修复完成后农田土壤中苯并[a]芘环境当量总浓度低于0.53 mg/kg。
為指導正確評價多環芳烴汙染農田土壤生態脩複效果及環境風險，根據遼寧省農田土壤多環芳烴汙染狀況、多環芳烴汙染農田土壤生態脩複技術特點，參攷國內外相關標準，應用生態風險模型，建立遼寧省地方標準（DB 21/T 2274-2014）---多環芳烴汙染農田土壤生態脩複標準，提齣瞭生態脩複完成後農田土壤中總多環芳烴濃度和苯併[a]芘環境噹量總濃度限值。主要內容為：生態脩複完成後農田土壤中總多環芳烴濃度低于2 mg/kg，生態脩複完成後農田土壤中苯併[a]芘環境噹量總濃度低于0.53 mg/kg。

To assess the efficiency of ecological remediation of agricultural soils contaminated with polycyclic aromatic hydrocarbons (PAHs) and environmental risks correctly, a study on related standard was carried out. Based on PAH contamination situation of agricultural soil in Liaoning province and technical characteristics of ecological remediation of agricultural soils, a province local standard (DB 21/T 2274-2014) of Liaoning, namely standard for ecological re-mediation of agricultural soils contaminated with PAHs, was setup. In the process of standard formulation, domestic and international similar standards were referenced, and ecological risk model was applied, the limitation values for total PAH concentration and Benz[a]pyrene environmental equivalent concentration in agricultural soil after ecologi-cal remediation were proposed, they should be lower than 2 mg/kg and 0.53 mg/kg, respectively.
