The situation of chlorpyrifos in Mexico: a case study in environmental samples and aquatic organisms.

Chlorpyrifos (CPF) is one of the most commonly used organophosphate pesticides. Because CPF was described as a toxic compound without safe levels of exposure for children, certain countries in Latin America and the European Union have banned or restricted its use; however, in Mexico it is used very frequently. The aim of this study was to describe the current situation of CPF in Mexico, as well as its use, commercialization, and presence in soil, water, and aquatic organisms in an agricultural region of Mexico.

Hematological indices as indicators of inflammation induced by exposure to pesticides.

Pesticide toxicity, both acute and chronic, is a global public health concern. Pesticides are involved in abnormal inflammatory responses by interfering with the normal physiology and metabolic status of cells. In this regard, inflammatory indices aggregate index of systemic inflammation (AISI), monocyte-to-high-density lipoprotein ratio, monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte platelet ratio (NLPR), neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic immune inflammation index, and systemic inflammation response index (SIRI) have been used as predictive markers of inflammatory status in several diseases and also in acute poisoning events.

Preliminary survey of the occurrence of mycotoxins in cereals and estimated exposure in a northwestern region of Mexico.

Mycotoxins have several toxicological implications. In the present study, we evaluate the presence of aflatoxin B (AFB), ochratoxin A (OTA), and fumonisin (FB) in paddy rice, polished rice, and maize from the fields and markets in Nayarit State (Mexico). The results indicated the presence of AFB in 21.

β-Glucuronidase and Its Relationship With Clinical Parameters and Biomarkers of Pesticide Exposure.

Objective: This study determined β-glucuronidase activity and its relationship with clinical, biochemical, and pesticide-exposure biomarkers in workers occupationally exposed mainly to OP insecticides.

Methods: A cross-sectional study was conducted in pesticide applicators. Three study groups were established: reference group, moderate-exposure group, and high-exposure group.
