Environmental transmission of diarrheal pathogens in low and middle income countries

Globally more than half a million children die every year from diarrheal diseases. This Perspective suggests that reductions in diarrheal disease transmission in LMICs can be achieved by accounting for site-specific factors when designing environmental interventions. This is discussed in the context of the characteristics of the most important diarrheal diseases as well as environmental reservoirs.

A review of stereochemical implications in the generation of secondary organic aerosol from isoprene oxidation

The atmospheric reactions leading to the generation of secondary organic aerosol (SOA) from the oxidation of isoprene are generally assumed to produce only racemic mixtures, but aspects of the chemical reactions suggest this may not be the case.

Aqueous singlet oxygen reaction kinetics of furfuryl alcohol: effect of temperature, pH, and salt content

The rate constant for the reaction between furfuryl alcohol (FFA) and singlet oxygen (1O2) in aqueous solution was measured as a function of temperature, pH and salt content employing both steady-state photolysis (β value determination) and time-resolved singlet oxygen phosphorescence methods.

A strategic screening approach to identify transformation products of organic micropollutants formed in natural waters

Many transformation products (TPs) from organic micropollutants are not included in routine environmental monitoring programs due to limited knowledge of their occurrence and fate.

Methylmercury production in a chronically sulfate-impacted sub-boreal wetland

Net methylmercury (MeHg) accumulation in a chronically sulfate-impacted sub-boreal wetland is not higher than a nearby unimpacted wetland. MeHg accumulation in peat appears to be related to sulfur, but accumulation is decoupled from short-term methylation rates.

Phototransformation of pesticides in prairie potholes: effect of dissolved organic matter in triplet-induced oxidation

Despite the fact that triplet excited state dissolved organic matter (DOM) enhances phototransformation of pesticides by acting as a photosensitizer, it may also decrease the overall phototransformation rate through various mechanisms.
