Palabras clave: agroquímicos, exposición pasiva, dispersión de residuos, localidades rurales RESUMENEn diferentes proyectos realizados en Sonora, México, se comprobó la presencia de contaminación por agroquímicos en trabajadores y habitantes de localidades rurales aledañas a campos de cultivo. Para evaluar el peligro que representa para la salud de los habitantes la exposición pasiva de dichos compuestos, se requiere información confiable y actualizada sobre cultivos sembrados y plagas, así como cantidades, dosis y formas de aplicación de los plaguicidas utilizados, especialmente aquellos con potencial de riesgo para la salud. En este trabajo se propone un marco de referencia que permita identificar la información con que se cuenta a nivel local, como lo es el Distrito de Desarrollo Rural (DDR) 144-Hermosillo sobre cultivos y sus plagas, además de la intensidad y frecuencia de aplicación de plaguicidas por aspersión. En el periodo 2010 a 2014, nueve cultivos ocupaban el 80 % de la superficie sembrada en el DDR 144 Hermosillo y podían emplear 24 productos agroquímicos aplicados por aspersión. De éstos, los insecticidas organofosforados y herbicidas llegan a aplicarse de 16 a 211 t en 72 500 ha en una temporada, varios de estos plaguicidas son moderadamente persistentes en el ambiente y se consideran con efectos adversos a la salud por organizaciones nacionales e internacionales. Se concluye que en los predios agrícolas se asperjan suficientes cantidades de plaguicidas peligrosos, que pueden afectar la salud de los habitantes de localidades cercanas.Key words: agrochemicals, passive exposition, residue dispersion, rural communities Rev. Int. Contam. Ambie. 34 (1) 7-21, 2018 DOI: 10.20937/RICA.2018.34.01.01 M.I. Silveira-Gramont et al. 8ABSTRACT Different research projects in Sonora, Mexico, have proven contamination from pesticides in workers and locals living in communities near agricultural fields. To evaluate the health hazards from passive exposition of their inhabitants to such compounds, it is required reliable and updated information on the crops sown, their pests, as well as pesticide amounts, doses and forms of application, especially of agrochemicals that pose health risk potential. This work proposes a reference frame to identify the required information at a local level such as the Rural Development District (RDD) 144 Hermosillo, on crops, pests, besides the intensity and frequency of the application of pesticides by spraying. In the period from 2010 to 2014, nine crops occupied 72 500 ha (80 %) of the sown area in RDD Hermosillo, and could employ 24 most frequent agrochemical products applied by spray. Of those organophosphate insecticides and herbicides, 16 and 211 t were applied over 72 500 ha in one season. Several of these pesticides are moderately persistent in the environment and they are considered with adverse health effects by national and international organizations. It is concluded that in agricultural fields, enough quantities of hazardous pesticides are sprayed, which might possibly af...

“…The USGS state boundaries layer [51] was overlaid with the grid polygon layer to determine specific grids intersecting the U.S. Grids from the preprocessed UV Ery rasters from July 1980, 1990, 2000, and 2010 within the U.S. boundary were input into the segmentation procedure. Segmentation, which uses a watershed delineation method of merging/growing pixels across input bands exhibiting minimal variance [52], was performed on the U.S. grids in IDRISI Selva using the following parameters: window of 3, tolerance of 1 to 10 using intervals of 1, weight mean factor of 0.5, and weight variance factor of 0.5. Based on a visual comparison of resultant segments (polygons) from each year with a priori knowledge of latitude-driven trends in UV Ery , nine regions were created for modeling (Fig.…”

BackgroundUltraviolet B (UV-B) radiation plays a multifaceted role in human health, inducing DNA damage and representing the primary source of vitamin D for most humans; however, current U.S. UV exposure models are limited in spatial, temporal, and/or spectral resolution. Area-to-point (ATP) residual kriging is a geostatistical method that can be used to create a spatiotemporal exposure model by downscaling from an area- to point-level spatial resolution using fine-scale ancillary data.MethodsA stratified ATP residual kriging approach was used to predict average July noon-time erythemal UV (UVEry) (mW/m2) biennially from 1998 to 2012 by downscaling National Aeronautics and Space Administration (NASA) Total Ozone Mapping Spectrometer (TOMS) and Ozone Monitoring Instrument (OMI) gridded remote sensing images to a 1 km spatial resolution. Ancillary data were incorporated in random intercept linear mixed-effects regression models. Modeling was performed separately within nine U.S. regions to satisfy stationarity and account for locally varying associations between UVEry and predictors. Cross-validation was used to compare ATP residual kriging models and NASA grids to UV-B Monitoring and Research Program (UVMRP) measurements (gold standard).ResultsPredictors included in the final regional models included surface albedo, aerosol optical depth (AOD), cloud cover, dew point, elevation, latitude, ozone, surface incoming shortwave flux, sulfur dioxide (SO2), year, and interactions between year and surface albedo, AOD, cloud cover, dew point, elevation, latitude, and SO2. ATP residual kriging models more accurately estimated UVEry at UVMRP monitoring stations on average compared to NASA grids across the contiguous U.S. (average mean absolute error [MAE] for ATP, NASA: 15.8, 20.3; average root mean square error [RMSE]: 21.3, 25.5). ATP residual kriging was associated with positive percent relative improvements in MAE (0.6–31.5%) and RMSE (3.6–29.4%) across all regions compared to NASA grids.ConclusionsATP residual kriging incorporating fine-scale spatial predictors can provide more accurate, high-resolution UVEry estimates compared to using NASA grids and can be used in epidemiologic studies examining the health effects of ambient UV.Electronic supplementary materialThe online version of this article (doi:10.1186/s12940-016-0197-x) contains supplementary material, which is available to authorized users.

“…50 Approaches that incorporate geographical information at a regional scale are now common practice (e.g. [99][100][101][102][103] ). Soil and groundwater models are considered to be less appropriate for generic risk assessments for determining monitoring programmes, as they can be too site specific.…”

Risks from emerging contaminants (ECs) in groundwater to human health and aquatic ecology remain difficult to quantify. The number of ECs potentially found in groundwater presents challenges for regulators and water managers regarding selection for monitoring. This study is the first systematic review of prioritisation approaches for selecting ECs that may pose a risk in groundwater. Online databases were searched for prioritisation approaches relating to ECs in the aquatic environment using standardised key word search combinations. From a total of 672, studies 33 met the eligibility criteria based primarily on the relevance to prioritising ECs in groundwater. The review revealed the lack of a groundwater specific contaminant prioritisation methodology in spite of widely recognised differences between groundwater and surface water environments in regards to pathways to receptors. The findings highlight a lack of adequate evaluation of methodologies for predicting the likelihood of an EC entering groundwater and highlights knowledge gaps regarding the occurrence and fate of ECs in this environment. The review concludes with a proposal for a prioritisation framework for ECs in groundwater monitoring which enables priority lists to be updated as new information becomes available for substances regarding usage, physico-chemical properties and hazards.
