Pesticides in Greenhouse Runoff, Soil and Plants: A Screening
نویسندگان
چکیده
A research has been undertaken studying pesticide losses from areas with intense agricultural and horticultural productions such as vegetables, cotton, pot plants and flowers, taking grab and composite samples including using passive SPMD samplers in ditches, creeks, rivers and groundwater, in addition to greenhouse and imported products. Pesticides were frequently found, occasionally in high concentrations, both in the products and in the environment. Endosulfan could be detected in the products, in pot soil and in plants, and also in the water samples, even in areas where it has been banned for several decades. Dilute concentrations of endosulfan can be detected by using passive samplers.

Selection of plants for optimization of vegetative filter strips treating runoff from turfgrass.
Runoff from turf environments, such as golf courses, is of increasing concern due to the associated chemical contamination of lakes, reservoirs, rivers, and ground water. Pesticide runoff due to fungicides, herbicides, and insecticides used to maintain golf courses in acceptable playing condition is a particular concern. One possible approach to mitigate such contamination is through the implem...
متن کاملPhotoremediation of Carbamate Residues in Water
Pesticides are extensively world wide used for agriculture and for non-agricultural purposes. The major environmental concern of used pesticides is their ability to leach down to subsoil and contaminate the ground water, or, if they immobile, they could persist on the top soil and become harmful to microorganisms, plants, animal and people (Jha & Mishra 2005; Radivojević et al., 2008). Harmfull...
متن کاملSurface Runoff of Pesticides from a Clay Loam Field in Sweden.
Pesticides stored at or close to the soil surface after field application can be mobilized and transported off the field when surface runoff occurs. The objective of our study was to quantify the potential pesticide losses in surface runoff from a conventionally managed agricultural field in a Swedish climate. This was achieved by measuring surface runoff volumes and concentrations in runoff of...

Sustainable Agriculture satisfies human food and fiber needs, makes the most efficient use of on-farm resources and integrates natural biological cycles, enhances the quality of life for farmers and society as a whole, and sustains the economic viability of farm operations. A farm that is able to produce continuously, yet has negative effects on environmental quality elsewhere, does not support...
متن کاملToxicity persistence in runoff and soil from experimental soybean plots following insecticide applications.
Persistence of toxicity in runoff water and soil was investigated in experimental soybean plots subjected to successive runoff events following pesticide application. Runoff events were produced by irrigation using a sprinkler system. The pesticides applied were cypermethrin and endosulfan, which are widely used in soy production in Argentina. Toxicity tests were performed on two abundant compo...
