A History of Organic Geochemistry [PDF]

Oil & Gas Science and Technology, 2003
Organic geochemistry is the fruit of questions about the origin of petroleum, and for the time being, its development has been closely linked to that of petroleum exploration. It only became an autonomous science shortly after 1960. The years 1965-1985 were extremely productive: during this period, the mechanisms of the formation of oil and natural gas

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, EarlyView.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Preclinical Toxicity Screening of Sodium Dodecanoyloxybenzenesulfonate (LOBS) as a New Alternative Biocide Using In Vitro and In Vivo Models

Environmental Toxicology, EarlyView.
ABSTRACT Sodium hypochlorite is a well‐established biocide extensively used in both living and industrial environments; however, exposure to it or improper handling can harm the human body and the environment. Thus, safer alternatives to sodium hypochlorite are required.

Distribution and Bioconcentration of Polycyclic Aromatic Hydrocarbons in Surface Water and Fishes

The Scientific World Journal, 2012
To examine spatial distribution and bioconcentration of PAHs, water and fish samples were collected from Pearl River Delta in summer and spring, respectively. Particulate organic carbon, dissolved organic carbon, biodegradable DOC (BDOC), and chlorophyll
