摘要:农田土壤重金属污染问题日益凸显,已成为影响生态农业发展的主要问题之一,越来越受到人们的关注。小尺度范围的农田重金属空间分布特征研究能更为有效地指导土地精准管理。本文对珠海市新马墩村农业园区土壤、灌溉水、典型农作物、主要施用化肥进行采样分析,开展了小尺度农业园区土壤重金属分布特征及风险评价研究。结果表明:研究区表层土壤Cd元素含量较高,其平均值是珠江三角洲土壤背景值0.11 mg/kg的3.7倍,处于中度污染级别、强生态危害程度,与长期大量施用含镉磷肥(磷肥Cd含量均值20.5 mg/kg)有关。Cu、Pb、Zn、Cr、Ni、As、Hg元素含量平均值低于土壤环境质量一级标准值,处于轻微危害程度。4个土壤剖面中8种重金属分布呈现不同特征,主要受土壤质地的不均一性、岩性不连续性影响。灌溉水样品和5种典型农作物可食部分重金属均未超标,白菜、无花果对重金属富集能力较强,青枣、火龙果、天冬富集能力较弱。因此,本研究提出园区应减少磷肥使用量,重视镉潜在生态风险,优先种植对重金属富集能力较弱的品种,以降低土壤中重金属对农产品品质的影响。

Distribution Characteristics and Risk Assessment of Heavy Metals in Soil from an Agricultural Park of Xinmadun Village, Zhuhai City

ABSTRACT

BACKGROUND:

The problem of heavy metal contamination in farmland is more and more serious, and has become one of the main factors that restrict the development of ecological agriculture, which has raised attention.

OBJECTIVES:

To study spatial distribution characteristics of heavy metals in small scale farmland and use it as an effective guide for land management.

METHODS:

Soil, irrigation water, agricultural products and chemical fertilizer from an agricultural park in Xinmadun village, Zhuhai.

RESULTS:

It was revealed that the content of Cd in surface soil was relatively high, with the average value 3.7 times higher than the background value in the Pearl River Delta (0.11 mg/kg), classified as moderate pollution scale and serious potential ecological risk. The Cd pollution was related to the long-term cadmium phosphate fertilizer overuse having a mean cadmium phosphate fertilizer content of 20.5 mg/kg. The average contents of Cu, Pb, Zn, Cr, Ni, As, and Hg in surface soil were lower than the soil environmental standard Ⅰ and was classified as low potential ecological risk. The vertical distribution of 8 heavy metals in four soil profiles presented different characteristics, which was influenced by the heterogeneity and discontinuity of the soil. The concentrations of heavy metals in the irrigation water and edible parts of five agricultural products were in compliance with standards. Bok choy and ficus carica had higher potential in enriching heavy metals, while aspartame, jujube and dragon fruit had lower enrichment potential.

CONCLUSIONS:

It is suggested to reduce the usage of cadmium phosphate fertilizer in the agricultural park, pay attention to the potential ecological hazard of cadmium, and choose breeds of crop that have weaker heavy metal enrichment capacity.

KEY WORDS: agricultural park, soil, heavy metals, risk assessment, agricultural products, phosphate fertilizer

HIGHLIGHTS

(1) The spatial distribution characteristics of heavy metals in small scale farmland were investigated.

(2) The high content of Cd in the surface soil of Xinmadun village, Zhuhai city was related to the long-term overuse of cadmium phosphate fertilizer.

(3) The distribution characteristics of heavy metals in the soil profiles of Xinmadun village, Zhuhai city were significantly influenced by the heterogeneity and discontinuity of the soil.
