Phthalates were first introduced in the 1920s and quickly replaced the volatile and odorous camphor. In 1931, the commercial availability of polyvinyl chloride (PVC) and the development of di(2-ethylhexyl) phthalate (DEHP) began the boom of the plasticizer PVC industry.
Polyvinyl chloride is formed in flat sheets in a variety of thicknesses and colors. As flat sheets, PVC is often expanded to create voids in the interior of the material, providing additional thickness without additional weight and minimal extra cost (see closed-cell PVC foamboard ).
PVC and plastic production produces PVC dust [59] [60] with mortality confirmed among vinyl and polyvinyl chloride workers after reanalysis of data [61] and coronary artery disease and cancer death among vinyl chloride exposed workers [62] Rubber chemical manufacturing impacting mortality among these workers.

Multiple cars containing vinyl chloride spilled their contents onto the ground, which is suspected of leading to contamination of the water, and the air after a fire. Studying vinyl chloride's ...
Weight loss medications like Contrave (a combination of naltrexone and bupropion) block the reward pathways that make it tempting to binge eat, but there are side effects.
Between microplastics of polypropylene (PP) and polyvinyl chloride (PVC), PVC demonstrated greater toxicity to Chlorella pyrenoidosa, overall negatively impacting their photosynthetic ability. This effect on photosynthesis is likely due to the 60% reduction of algal chlorophyll a associated with high PVC concentrations found in the same study ...
“With Robbie, you can see the direct results of weight loss.” Dr. Sue Decotiis, a weight loss specialist, told The Mail: “He looks like a totally different person. “He has a longer face ...
Certified products may not contain listed chemicals as intentionally added ingredients above 1000 ppm. According to C2CPII, chemicals are selected for inclusion on the list due to their tendency to accumulate in the biosphere and lead to irreversible negative human health effects. Additionally, several substances were selected due to the ...
