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.
Pesticide toxicity in humans can be classified by the nature of exposure, by the route by which exposure occurs, or by the body function or system affected. Generally, any poison is more toxic if ingested by mouth than if inhaled, and more toxic if inhaled than if by dermal (skin) exposure.
