Summary

Nitrapyrin is a nitrification inhibitor that is co-applied with N-fertilizer in agroecosystems. Over the course of one year (March 2016 to June 2017), 192 water samples from seven streams across Iowa and Illinois were analyzed for nitrapyrin, its degradate 6-chloropicolinic acid (6-CPA), and three widely used herbicides acetochlor, atrazine, and metolachlor. Additional environmental samples were collected and analyzed in spring 2017: 63 water samples from eight subsurface drains, and 33 soil samples from a field in Iowa that received direct application of nitrapyrin (only for nitrapyrin and herbicides). Nitrapyrin was detected in all seven streams (56% detection) with concentrations ranging from 4 to 1,200 ng/L; 6-CPA was detected [...]

Purpose

The purpose of the data collection was to document the occurrence and transport of nitrapyrin in soil, subsufrace drains, and streams and to document the temporal conditions under which transport is enhanced. This data set is the first to document transport after both spring and fall applications, and this data set can be used to direct future toxicity and ecological studies focused on nitrapyrin.
