Abstract/Contents:"Using simulation experiment and spot monitoring method, the transfer laws of chlorothalonile, cypermethrin and fertilizers on the golf course lawn with water and their residue changes in soil and plants were studied. At high, medium and low concentration, the transfer contents of chlorothalonile and cypermethrin in soil and leaching liquor were below the detection limits. Their residual quantity in lawn plants after medication 7 d were 23.8, 505.0 and 771.5 μg/kg respectively. The total transfer mass of P in water after fertilization 22 d was only 0.45% of fertilization amount. Total transfer mass of three kind nitrogen (NH+4, NO2- and NO3-) with water was 75.2% of fertilization amount. The maximum concentration in water could reach 1 500 times of V-grade water quality standard in GB3838-2002 Water Quality Standards for Surface Water Quality [water quality standards for the surface water quality], indicating that three kinds of nitrogen were potential pollution sources of surface water and ground water on the golf course lawn. The spot monitoring results showed that the nitrogen content of upstream and downstream lake on the golf course had the difference of 0.022 2 mg/L and no great influence on outside. After medication 3 d,pesticide was not detected in surface water, leaching liquor and soil of golf course and the maximum residual quantity in green plant samples reached 1 349 μg/kg."
