Strategic Line II

Oxidative stress

Responsible: Dra. Tania Zenteno Savín

It has been determined that in the region of Northwest Mexico there are biological, chemical and physical factors which represent a risk to environmental health. It's known that this tropical region has one of the highest indexes of UV radiation in the world. Organisms living in Baja California Sur face extreme environmental conditions including salinity, drought, temperature and hypoxia. Baja California Sur is in a zone exposed to naturally-occurring environmental disturbances such as heavy-metal deposits, hurricanes and harmful algal blooms (red tide).

The presence of organochlorate and organophosphate pesticides has been noted, as well as heavy metals, in various coastal zones of Baja California Sur, Nayarit, Sinaloa y Sonora; especially the pesticide lindane, considered among the 17 pesticides most dangerous to human health. Continuing urban development, the growing tourist industry and displacement of endemic and migratory species suggest the introduction of pathogenic microorganisms into zones where they have not been reported. Additionally, on the national level Baja California Sur is in third place for prevalence of metabolic syndrome. Metabolic syndrome, along with cancer, tumoral diseases and cardiovascular pathologies, is among the top causes for morbidity and death in Mexico.

Based on the above and with results from the Strategic Line of Environmental Health and Biomedicine, we will use tools on the physiological, biochemical and molecular levels to determine the effects of those environmental disturbances to the health of marine and terrestrial ecosystems, and organisms including humans.

Research focus:

1. Determination, valuation and effects of naturally-originating environmental disturbances (environmental variability).
Coordination: Dra. Sara Cecilia Díaz Castro

Specific Objectives

  • Evaluate the hydrological resources of the state of Zacatecas, facing climate change.
  • Utilize principal indicators of oxidative stress to evaluate the effects of environmental hypoxia exposure in wild populations of marine organisms.
