Summary
Pollen levels in Monterrey, Mexico, were highest in spring, dominated by tree pollen, particularly ash (Fraxinus spp). Low pollen counts occurred in summer and fall, with grass and weed pollen showing perennial presence.
Area of Science:
- Aerobiology
- Palynology
- Environmental monitoring
Background:
- Limited data exists on airborne pollen prevalence in Mexico.
- Understanding local pollen types and concentrations is crucial for public health, especially for allergy sufferers.
Purpose of the Study:
- To characterize the annual prevalence and identify airborne pollen types in Monterrey, Mexico.
- To establish a baseline for aerobiological data in the region.
Main Methods:
- Atmospheric pollen was collected continuously over 2004 using a Hirst air sampler (10 L/minute airflow).
- Pollen identification and quantification were performed using light microscopy.
- Monthly and total annual pollen counts were calculated.
Main Results:
- The highest pollen concentrations were observed in February and March (289 and 142 grains/m³ per day).
- Tree pollen constituted the majority (72%), with Fraxinus spp. being the most abundant (27.5%).
- Weed and grass pollen (Gramineae/Poaceae) showed perennial presence with seasonal peaks.
Conclusions:
- Monterrey experiences significant seasonal variations in airborne pollen, with a spring peak dominated by tree pollen.
- Fraxinus spp. is a major contributor to the annual pollen load in Monterrey.
- This study provides essential baseline data for aerobiology and allergy management in the region.

00:53Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
01:17Precipitation and Co-precipitation
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
01:18Variation of Atmospheric Pressure
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

01:03Precipitation Gravimetry
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

01:19Precipitation Titration: Endpoint Detection Methods
In argentometric precipitation titrations, endpoints can be detected visually by the Mohr, Volhard, and Fajans methods. In the Mohr method, adding a soluble chromate indicator gives an initial yellow color to the analyte solution. As the titrant is added, the first excess of silver ions forms a red silver chromate precipitate, marking the endpoint. The solution pH should be maintained at about 8 by adding solid CaCO3.
In the Volhard method, a standard excess of AgNO3 is first added to the...

01:24Antiasthma Drugs: Methylxanthines
Theophylline, a member of the methylxanthine class of bronchodilators, has long been used in asthma management. While its exact mechanism of action is not fully understood, it is believed to have multiple effects on various cellular processes.
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...
