Meets course-level objective AIM 1 & AIM 2 and weekly objective 1
First, use this video to understand how to use the TCEQ website: https://youtu.be/AmqEEUIhRzI
This video will show you how to search the air monitor called Beaumont Mary.
Then use the reading from the prior week (week 2) to read more about H2S.
In this reading you will see that “People usually can smell hydrogen sulfide at low concentrations in air ranging from 0.0005 to 0.3 parts per million ” (0.3ppm)—this is your threshold.
Next, to answer the below questions visit the TCEQ website to identify if H2S was at or above 0.3ppm in Beaumont, Texas. You might have to covert ppm to ppb. Google has converters.

1. Step 1: Explain in detail (by providing 3 examples) how industry can negatively impact health. Use the content from this week to back up your explanation + Link your explanation to an ACADEMIC journal article + include the reference to the article. (2-3 sentences)
You can also use the following link for background information:
2. Step 2: now your goal is to research how often H2S is at or above 1ppm in Beaumont. You do this by researching the TCEQ air monitors. Using the TCEQ website review the Beaumont Mary air monitor. Pick the month of Feburary 2022 and list the daily H2S rates for the first week of Feb. Next, List which DAY and TIME had the highest H2S rate?
For more information on how to read the air monitor watch the video
Exposure Limits for Hydrogen Sulfide (
NIOSH Recommended Exposure Limit (REL): 10 ppm, 10-minute ceiling
Concentration considered immediately dangerous to life and health (IDLH): 100 ppm
ACGIH® recommends a threshold limit value (TLV®) of 1 ppm as an 8-hour time weighted average (TWA) and a short-term exposure limit (STEL) of 5 ppm.
3. Step 3: Explain in 2-3 sentences what your findings from reading the Beaumont Mary air monitor could possibly mean to environmental health of children and elderly living in the area. Hint- use the power point presentation from week 4. Link your explanation to an ACADEMIC journal article + include the reference to the article.
