Deleterious Substances in Aggregate

Deleterious Substances in Aggregate

Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...

Background:

Secondary lead smelters can release lead into the environment.
Lead contamination in soil poses risks to human health.
Comprehensive environmental monitoring is crucial for assessing exposure.

Purpose of the Study:

To assess lead contamination in soil, dust, and blood near secondary lead smelters.
To map soil lead concentrations using geostatistical methods.
To analyze the distribution of lead in the environment surrounding industrial sites.

Main Methods:

Collection and analysis of over 2700 soil samples, 1000 blood samples, and 840 house dust samples.
Application of geostatistical techniques to soil data for spatial analysis.
Development of isopleths to visualize soil lead concentrations.

Main Results:

Identified spatial patterns and distributions of soil lead concentrations.
Geostatistical analysis provided detailed insights into lead contamination.
Data on lead levels in soil, dust, and blood were collected and analyzed.

Conclusions:

Geostatistics is an effective tool for mapping environmental lead contamination.
The study provided a comprehensive assessment of lead exposure near smelters.
Understanding lead distribution is vital for targeted remediation efforts.
