Overview. Gastric intubation via the nasal passage (ie, nasogastric route) is a common procedure that provides access to the stomach for diagnostic and therapeutic purposes.
The impact of pesticides consists of the effects of pesticides on non-target species. Pesticides are chemical preparations used to kill fungal or animal pests. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields.
that unite the soilâs chemical and physical properties for âsoil health.â We know a lot about how pesticides influ-ence the target, and even some of the effects on plants and other aboveground organisms that are not the tar-gets of pesticides. But we donât know much about how pesticides interact with soils and soil organisms, and thereâs far greater species diversity belowground than aboveground. The following article is a summary of my understanding on how pesticides affect the soil biota, and how that could affect soil ecosystem function specifi-cally in a no-tillage system. Pesticide Effects on Soil Biology: Part I by Jill Clapperton SCIEnCE Jill Clapperton is a soil ecologist and land resource consultant, based in Montana. 1 Editors: The grouping of organisms into fauna and flora is a bit arbitrary at times, e.g., protozoa somewhat blur the distinction between animal and plant,
