WebPetroleum hydrocarbons (PHs) are also highly toxic environmental pollutants comprising a mixture of several hydrocarbons. From: Microbial Biodegradation and Bioremediation … WebLPG is basically a mix of hydrocarbons with 3 (C3 – propane) and 4 (C4 – butane) carbon atoms, receiving its name from the fact that it can be liquefied by compression at room temperature. This product may be used as domestic fuel for cooking and heating.

WebVolatile pollutants such as hydrocarbons have, during many years, been analysed in small concentrations in air, water, food, pharmaceutical solutions, and human blood and tissues. It has also been shown that such substances have unexpected consequences for cell cultures and scientific experiments. WebAbstract. Polycyclic aromatic hydrocarbons (PAH) comprise the largest class of cancer-causing chemicals and are ranked ninth among chemical compounds threatening to humans. Although interest in PAH has been mainly due to their carcinogenic property, many of these compounds are genotoxic, mutagenic, teratogenic, and carcinogenic.
