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 chemicals and their metabolites may be stored or accumulated within an organism or be eliminated as waste. Metabolism can be induced based on exposure. Because pesticide residues may accumulate within organisms, special precautions in harvest or slaughter must be observed with the treated commodities.
