A Review of Sampling Approaches to Off-Target Pesticide Deposition

•Off-target deposition is a major route through which pesticides enter the environment.•A variety of sampling devices are used for pesticide deposition; paper or glass are most common.•Paper based samplers may protect sampled pesticides from degradation.•Air dispersion models tend to under-predict or over-predict pesticide deposition.•Standardised approaches to pesticide deposition are preferable.
