Historic treatment of rail ties in the Houston, Texas Fifth Ward and Kashmere Gardens neighborhoods has exposed residents to cancer-causing soil contamination.

It was used as a wood treatment facility. Starting in 1919, the site was contaminated with creosote. Creosotes are a category of carbonaceous chemicals formed by the distillation of various tars and by pyrolysis of plant-derived material, such as wood or fossil fuel. They are typically used as preservatives or antiseptics.
The residue remaining in the autoclave vessel is a dark, syrupy mass called creosote, which is composed mainly of phenolic acid and cresylic acid. The original composition of creolin is a creosote tar oil, caustic soda, soaps, and very little water. It is of low technology and a very powerful disinfectant. [1]

Some plants may cause mild tummy upset and vomiting when ingested. But, unfortunately, others can cause life-threatening symptoms such as heart problems, seizures, or death, says Dr. Wismer.
Researchers using high-tech air monitoring equipment rolled through an industrialized stretch of southeast Louisiana in mobile labs and found levels of a carcinogen in concentrations as much as 20 ...
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
