“…The impact of these chemicals on the nutritional composition of cereal grains is of great concern. Studies have shown the prevalence of these chemical residues in stored products, affecting the health and nutritional value derived from their consumption [ [23] , [24] , [25] ]. The quality of these chemically stored grains is mainly influenced by the duration and method of storage [ 26 ] .…”

“…Principal Component Analysis (PCA) is a multivariate tool used to interpret and study the pattern of multivariate characteristics (original variables) of several objects using the graphical representation of the projection of this information in two or three axes (latent variable axes) selected to contain maximum information given by the original variables (Da Silva & Camões, 2010). PCA has been widely used to reduce a set of original variables and to extract a small number of latent factors (principal components, PC) for analyzing relationships among the observed variables (Martin et al, 2013).…”

Pesticides are extensively used in the cultivation and postharvest protection of citrus fruits, therefore continuous monitoring and health risk assessments of their residues are required. This study aimed to investigate the occurrence of pesticide residues on citrus fruits and to evaluate the acute and chronic risk for adults and children. The risk ranking of twenty-three detected pesticides was carried out according to a matrix ranking scheme. Multiple residues were detected in 83% of 76 analyzed samples. In addition, 28% contained pesticides at or above maximum residue levels (MRLs). The most frequently detected pesticides were imazalil, azoxystrobin, and dimethomorph. According to the risk ranking method, imazalil was classified in the high-risk group, followed by prochloraz, chlorpyrifos, azinphos-methyl, tebufenpyrad, and fenpiroximate, which were considered to pose a medium risk. The majority of detected pesticides (74%) posed a low risk. The health risk assessment indicated that imazalil and thiabendazole contribute to acute (HQa) and chronic (HQc) dietary risk, respectively. The HQc was negligible for the general population, while the HQa of imazalil and thiabendazole exceeded the acceptable level in the worst-case scenario. Cumulative chronic/acute risk (HIc/HIa) assessment showed that chronic risk was acceptable in all samples for children and adults, while the acute risk was unacceptable in 5.3% of citrus fruits for adults and 26% of citrus fruits for children. Sensitivity analyses indicated that the ingestion rate and individual body weight were the most influential risk factors.
