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.
A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling or mitigating any pest. (Source: EPA) Pesticides often refer to the type of pest they control, e.g. insecticides kill insects and other arthropods; miticides or acaricides kill spider mites. All pesticides are regulated by the Environmental Protection Agency (EPA).
