By means of a modelling tool an analysis was made of the local variation in the use of pesticides in the province of Utrecht in The Netherlands, and the potential environmental impact of pesticide emissions on the aquatic ecosystems. The aim of this study was to identify and quantify the major sources of pesticide use and environmental impact, taking the regional variation of pesticide use into account. The analysis was targeted at different levels: detailed (individual active substances, individual agricultural crops, civil land-use types, hydrological catchment basins) and globally covering agricultural use, non-agricultural use (some civil sectors) and recreational shipping. The results can be used for the (re)design of environmental monitoring programmes of pesticides in surface waters and for the development of region based policies towards sustainable pesticide use. The analysis tool that was developed is considered to be applicable for other regions as well.

Biodegradation Efficiency

A strain B1 belonging to Pseudomonas aeruginosa with high petroleum-degrading efficiency was isolated from Dagang oil-field wastewater treatment plant. More than 80% petroleum-degrading efficiency was obtained at 32°C, 200 r/min. According to the orthogonal test, the environmental impact factors influencing petroleum-degrading efficiency of the strain were investigated. The optimum environmental conditions for petroleum degradation were as follows: temperature was 40 °C, pH 8.0, oil inoculation 1 mL, nitrogen content 0.05 g. And the biodegradation efficiency of the strain reached 86.1%.
