Canadian Water Quality Guidelines for the Protection of Agricultural Water Uses - Dinoseb
ثبت نشده
چکیده
The rate of volatilization of dinoseb may depend on soil acidity, temperature, surface soil moisture, the method of application, and the type of formulation (Kaufman 1976). Cohen et al. (1984) reported a volatilization half-life of 26 d. The significance of volatilization has been evidenced by the killing of plants by dinoseb vapours (Davis et al. 1954). Photodegradation is a major fate process, with half-life values of <1–30 h for plant and soil surfaces (Matsuo and Casida 1970; Hawkins and Saggers 1974; Dinoseb Task Force 1985). The atmospheric photooxidation half-life of dinoseb was estimated to be between 12.2 and 122 h (Syracuse Research Corp. 1989).

متن کاملSpatial and Temporal Evaluation of Water Quality in the Kashkan River
The Kashkan River basin is one of the most important watersheds in the west of Iran, where major urban, agricultural and livestock regions are located in its catchment area. The aim of the study reported here is to evaluate the spatial and long temporal variations of surface water quality in the Kashkan River by using Water Quality Index, which aggregates different parameters and their dimensio...
متن کاملAssessment of water quality in Blinaja River Basin (Kosovo) using the Canadian Water Quality Index (WQI)
Kosovo has limited natural water resources which should be well managed. This is recently realised through quantitative and qualitative monitoring of both surface and groundwater and by characterizing their quality according to their destination. In this paper, the Water Quality Index (WQI) developed by the Canadian Council of Environment Ministers (CCME WQI) was applied to evaluate the groundw...
متن کاملWater Quality Assessment of Dorudzan Reservoir(Shiraz) for Drinking and Irrigation Uses
Background and Purpose: Today, by increasing different pollutants, the continuous monitoring of surface waters is essential. Dorudzan Dam is one of the main sources of surface water in Fars Province, Iran; hence, the current study investigated the quality of Dorudzan Reservoir for drinking and irrigation consumptions. Materials and Methods: In this study, various physicochemical parame...
متن کاملAssessment of the presence of metals and quality of water used for irrigation in Kwara State, Nigeria
In Nigeria irrigated agriculture is an important tool for economic growth, food security, and poverty reduction during dry periods of rain-fed agriculture. The concentration and composition of dissolved constituents in water determines its quality for irrigation use. Water quality studies strongly suggest that agriculture is a leading source of water quality problems, due to pesticides and othe...
