This study aimed at assessing the potential of near infrared reflectance spectroscopy (NIRS) for determining chlordecone content in Andosols, Nitisols and Ferralsols from Martinique. Using partial least square regression, chlordecone content conventionally determined through gas chromatography-mass spectrometry could be correctly predicted by NIRS (Q(2) = 0.75, R-2 = 0.82 for the total set), especially for samples with chlordecone content <12 mg kg(-1) or when the sample set was rather homogeneous (Q(2) = 0.91, R-2 = 0.82 for the Andosols). Conventional measures and NIRS predictions were poorly correlated for chlordecone content >12 mg kg(-1), nevertheless ca. 80% samples were correctly predicted when the set was divided into three or four classes of chlordecone content. Thus NIRS could be considered a time- and cost-effective method for characterising soil contamination by chlordecone. specialized Near infrared reflectance spectroscopy (NIRS) Organochlorine pesticide Chlordecone Soil contamination 068 021 157 11 3120-3125 2009 0269-7491 https://www.documentation.ird.fr/hor/fdi:010048217 10.1016/j.envpol.2009.05.026 0269-7491 [F B010048217] https://www.documentation.ird.fr/hor/fdi:010048217 https://www.documentation.ird.fr/intranet/publi/2009/10/010048217.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-11-09 2023-10-04 fdi:010048217 fre
