Enviroblog: Our old bones release lead into our bloodstreams–a delayed hazard of leaded gas

Seniors worry about decreasing bone density because of increased risks of fractures. A new study suggests that as bones dissolve, they release old lead deposits along with calcium, leading to delayed lead exposure as well.

Well-Water Consumption and Parkinson’s Disease in Rural California.

4 Mar

Why are there no pesticide well water standards? I have spoken to landowners who would rather not have their well water tested for fear that their property values will go down. Aquifers are connected.

Why it is important to read the herbicide label for recommended rate and ‘INACTIVE’ ingredients . . .

29 Feb

How many people read the label before going out and spraying the weeds in their back yards? Home owners are renowned for believing that if some is good, more must be better. Do they use protective gear like long sleeves? “In the summer? Are you kidding? No way!” What about the inactive ingredients? Obviously if they are inactive ingredients they must be less toxic than the active ones, right? WRONG!
A few weeks ago in my Weed Science course at UC Davis (a fabulous class, I recommend it highly), I learned that much suffering could have been averted if only Agent Orange were made more carefully, without as much Dioxin (a very hazardous contaminant that was not needed for defoliation, but was sprayed right along with the defoliants during the Vietnam War).
In a 5 part series, the Chicago Tribune Watchdog column story goes into some depth and interviews victims of this manufacturing oversight.

Check it out. Why is this not taught in history class? We have enough chemistry to understand this in high school. Please give us your 2 cents on this one!!
